Error H2 in the washing machine Indexit

The washing machine of this brand can not draw water due to such reasons:

  • The impossibility of getting water into the machine: the faucet, which supplies water, is turned off, there is no water in the riser. It may be that there is water, but the sieve, which cleans the water from hardness, is clogged or the inlet valve is defective.
  • Such an error can also occur in Indesit washing machines when water enters the drum, but immediately drains out. Usually water flows into the drain, but it may be that the machine has a serious leak.

If there is a question of what to do with error H20 in the washing machine Indesit, you need to find out why the water immediately drains. Most often this happens because the drain hose lies low on the floor. In order to avoid problems in the future, it is necessary to attach the drain hose to the fixture, which is located on the back of the machine.

Error code H20 in the washing machine Indesit

Collect and load all the dirty laundry in the drum of your indispensable helper in the household, then select and run the desired washing program. And as a result the display shows error H20. Such a failure can be displayed, regardless of the selected program, stop at all, not even starting to pump water, or try to get the amount of water that does not match the selected program, to pump much more than required, or to pump, then immediately without starting the washing process to pump it out.

In very rare cases, this failure may be displayed at the start of the rinse mode, but this action and stops.

In addition, the specified malfunction most often occurs without a certain pattern of its display. You should know that only the H20 malfunction can both safely spin and drain water without stopping.

Pay your attention! Suddenly you find that your Indesit machine displays several faults in combination with H20, then the cause of the failure of your device to work, you need to look for another fault.

Error codes of washing machines Ariston and Indesit with control system EVO-II

As you know, most modern washing machines have a diagnostic system that captures the failures that occurred during operation and displays them in the form of error codes on the control panel. In addition, this system allows you to perform an autotest program, with which you can test the performance of SM in various modes. The diagnostic system makes it easier to search for and eliminate possible defects in the SM arising during the operation of these machines.

This system is also available in modern washing machines with electronic control systems made by INDESIT COMPANY (formerly called MERLONI).

In all this company’s automatic washing machines with the outdated EVO-I control system, the error codes were determined by the number of flashes of the LED indicator (in the series). For example, if the indicator flashes 5 times at short intervals, and after a pause the cycle of flashes repeats, it corresponds to error code F05. Deciphering an error code is no longer difficult, for example, for F05 it is a problem with the water drain (pump, clogging in the drainage circuit, pressostat).

Usually, when an error occurred in these SMs, the knob of the command device started to rotate and the execution of the current washing program stopped. Detailed description of EVO-I electronic modules is given in another article.

error, washing, machine

In SM, based on the EVO-II control system, the situation is somewhat more complicated. Since these machines differ both by the set of functions performed and by the design (for example, different control panels), on some low-cost SMs (without display, for example, in models of AVL series, etc.) it is possible to read the error codes of the control panel.) Many repairmen have troubles with the order of reading the error codes. Codes in them are determined by a combination of light of certain LED indicators. The easiest way to read the error codes is on display models (e.g. AVD bay controllers, etc.).). They are displayed directly on the indicator.

Error codes on INDESIT and ARISTON EVO-I/II series also can be calculated with special diagnostic key (SAT), which is connected to the service socket of LG. The key also makes it possible to test the CM in different modes: both autonomous and under the control of an external personal computer.

Let’s take a closer look at the process of reading error codes in INDESIT, ARISTON EVO-II CMs without using a diagnostic key.

Fault codes and how to read them

As it was noted above, in the EVO-II SMs with display (AVD linear series) error codes are displayed on LCD display 1

Fig. 1 Front panel of the EVO-II CM with display (AVD line)

In Fig. 2 front panel of AVL line SM.

In this case, the error codes are read by the DISPLAY indicator (LED 4) and the lighting of buttons DISPLAY TIMER (KN 1), SUPER WASH (KN 2), SOFT WASH (KN 3) and RINSE RINSE (KN 4).

In fact, the “secret” of identifying fault codes on EVO-II control panels with an LED display is quite simple. Each indicator is a digit of a binary error code. The very process of calculating the error code number is to match specific indicators to specific digits of the binary code and translate that code into decimal notation.

In this case. KH 4 is the first digit of the binary code, KH 3 is the second, KH 2 is the third, KH 1 is the fourth and LED 4 is the fifth.

If we return to the error code F05 as an example, the digit 5 in the binary code will look like: 00101 (5 digits, indicators KH 2 and KH 4 are lit).

And yet, in order not to bore the readers with the translation of numbers from one number system to another, here is a universal table (tab. 1) To determine the error codes.

And now let’s stop in details on error codes given in the table. 1, that is, let’s find the causes of faults and ways to eliminate them (washing machine). In fact, all this information is summarized in Tab. 3.

Table 3 Description of SM EVO-II error codes (AVD and AVL series)

Skin errors Possible causes and remedies Note
F01 Short circuit (triac) in supply line of driving motor Check possible water leakage on connector J9 Check connection block of driving motor (possible cause of problem). Check drive motor terminal block (possible cause of the problem: chemical corrosion of the terminal block). Replace electronic module In 90% of such malfunctions are caused by a defect in the drive motor. If the motor is good. See. left column. The EEPROM has absolutely nothing to do with the firmware
F02 Drive motor is not running, tachogenerator circuit is short-circuited or interrupted. Check reliability of contacts on J9 connector of the electronic module. Check electrical resistance of the tachometer (about 115. 170 0м). Resistance is measured between pins 1 and 2 of connector J9. In case of a short circuit in this circuit, disconnect J9 and check the wiring on the tacho sensor side. If the SM is equipped with an asynchronous servo motor, check whether pins 6 and 7 of connector J9 are electrically connected to the transducer. Replace motor Replace electronic module The tachometer may be frothy, or there may be a loose connection in the socket. If this sensor is shorted. Look for burnt-out tracks on the electronic module and 2-3 burnt-out resistors. This has nothing to do with flashing of non-volatile EEPROM
F03 The NTC temperature sensor circuit is shorted or open, or the heating element relay is stuck Check the contact reliability of J8 connector. Check the temperature sensor, taking into consideration that its resistance at ambient temperature (20°C) is 20 kOhm (this can be measured on pins 11 and 12 of J8 connector). If the result is different, check the integrity of the wiring from the module to the sensor. Replace the NTC temperature sensor. Replace the electronic module If the actions in the left column do not find the faulty element, re-flash the contents of the non-volatile memory EEPROM
F04 Level sensor generates signals Empty tank and overflow simultaneously The reason of this defect is that the contact group “Empty tank” in the sensor “stuck”, in this case the SM pours the water up to the overflow level. The drain pump starts automatically when this water level is reached. Check the quality of the connections of J3 connector on the electronic module. Check the status of the level sensor (on the pins of the connector and):. contacts 2-4 closed. Empty tank level;. contacts 2-3 closed. level “FULL BAT”;. contacts 2-1 closed. the “overflow” level (at least half the level of the boot lid glass). Replace level sensor. Replace electronic module EEPROM firmware has absolutely nothing to do with it
F05 Drain pump is blocked (does not work) or level sensor generates “empty tank” signal after finishing draining. Check reliability of connections in the connector J9. At the moment when the pump is supposed to work, you can check whether there is 220V AC voltage between pins 8,9 of connector J9. Check the filter and drain hose. Replace drain pump. Check voltage between pins 8,9 of connector J9 often such defect is caused by foreign particles in the pump. Efficiency of the drain pump can be checked by connecting it to 220V AC voltage. The EEPROM firmware has absolutely nothing to do with it
F06 Not used in the AVD and AVL series.
F07 If there is no water in the tank after the filling operation, the heating element will not be energized. This is a safety feature because without water the heating element can burn out. Possible causes:. There is no water in the water supply or the water pressure is too low;. The water inlet valve is defective;. Blockage in the water intake pipe;. The level sensor is defective. After refilling (if any) the level sensor contact group Empty tank must be open. Its state is controlled, for example, on contacts 2 and 3 of connector J3 of the electronic module. Otherwise replace level sensor and electronic module in series The EEPROM firmware has absolutely nothing to do with it
F08 Heater relay on the module was permanently turned on (“stuck” contact set) or level sensor generates signals Empty and FULL tank simultaneously Check level sensor. see. error F04. Heating element control relay on the module should be checked by replacing. Check wires connection from L socket to level sensor. Check the connection of the heating element to the module (see “Connection of the heating element to the module” on page 31). pin 5 and 6 of connector ^3). Check operability of heating element. Replace level gauge. Replace electronic module The EEPROM firmware has absolutely nothing to do with it
F09 Error (failure) of EEPROM content, SETUP SM In many modules the EEPROM chip is soldered on the module’s board. The best option is if the chip is mounted on the adapter strip. In this case, the chip is easily removed and installed without soldering, when installing it on the module, pay attention to the coincidence of the setting keys (on the board and chip). If the EEPROM chip is good, replace the module as a whole (pay attention to the fact that the memory chip installed on it has the firmware intended for the particular SM model) Re-flash the content of the non-volatile EEPROM memory. Naturally, for this you need a programmer and the corresponding firmware file. Before re-flashing the memory chip, read its content and save it as a separate file so that the original firmware can always be recovered
F10 After the beginning of the water filling process (within the allotted time) the level sensor does not generate the signal FULL LAKE (provided that the signal Empty LAKE is passive, i.e. there is already water in the tank). Check level sensor. see. Check error F04. Check the electrical connection between the plug J3 on the electronic module and the level sensor. Replace the level sensor. Replace electronic module Most often such error can be caused by low water pressure when pouring water into the tank (the inlet pipe can be clogged, the inlet valve does not work correctly, etc.).). The EEPROM firmware has absolutely nothing to do with it
F11 No feedback signal on the discharge pump functionality (pump power supply circuit is broken or pump winding is broken). Check reliability of drain pump connection to electronic module. Check the drain pump winding resistance on connector J15, pins 1 and 2 (in case the product is equipped with Easy Door) or on connector J9, pins 8 and 9. Drain pump winding resistance should be about 170 ohms. Change drain pump. Replace electronic module The firmware of the non-volatile EEPROM has nothing to do with it
F12 No communication between the display module and the electronic module. Check that there are firm electrical connections between the J11 connector on the main electronic module and the display module. Replace basic electronic module. Replace display module In this case the choice is very small: either the indication module or the basic module is defective. In rare cases, the pad on the side of the display module is shifted. Also check the analogous block on the main module. Based on the experience gained in operating similar DMs, the EEPROM nonvolatile memory has not caused this type of defect
F13 Drying temperature sensor circuit open or short-circuited (drying oven only) Same procedure as for error F0Ç, but the drying temperature sensor circuit is different
F14 Dryer heating element does not work (only for SM with dryer). Check the supply circuit of the dryer heating element, as well as the heating element itself
F15 Dryer heating element relay not contact (only for SMD with dryer). Check dryer heating element power supply circuit, as well as heating element itself
F16 Drum blocked (only in upright loader). Check the blockage of the drum (power supply circuit of the blockage solenoid)
F17 The hatch door is not locked (or the door is open (for SM with Easy Door function)). Check 220V voltage on pins 3 and 4 of connector J4 (only not in the “STANDBY” mode), as well as between pins 3 and 5 of the door locking switch. Check activation of micro-switch for door lock feedback (with door closed and machine off) on pins 1 and 2 of electronic module connector J4. Check reliability of wiring from socket M to the hatch locking. Check if the lock clicks reliably. Replace the door lock. Replace electronic module. If the SM without the Easy Door function, carry out the same actions (see Fig.2). only check 220V voltage on pins 2, 3 of connector J4 and on pins 1, 3 of the door locking switch. The microswitch will not be tested in this case. because it is missing The firmware of the non-volatile EEPROM has absolutely nothing to do with it
F18 Communication error between the controller chips and the DSP (asynchronous motor control processor) on the main electronic module. Replacing the main electronic module Such an error is extremely rare, in any case, the author has not met it

EVO-II modules and their peripherals

It is known that the EVO-II washing machines have many modifications. They differ not only in functionality and appearance (only their control panels have several variants), but also in their electronic “stuffing. Let’s look at the main varieties of EVO-II modules. We must say right away that the external appearance of the indication modules (with LCD and LED indicators) is not presented in the figures. Actually it makes no sense, because the indication modules are quite simple and have only two connectors: one is intended for communication with the main module, and the second one is connected to the program selector.

H2O error in Indesit washing machine

H2O error appears on the display in the washing machine when there are problems with water.

The H2O code, if you recall your chemistry classes, is similar to the formula for water. Only if in chemistry H2O means an oxygen atom and two hydrogen atoms, then in the washing machine everything is simpler. it is a signal of a problem.

Error H2O in the washing machine Indesit means that for the allotted time water is not enough for washing or rinsing.

The error code H2O in Indesit brand washing machines can mean not only under- or over-discharge. If the drum receives more water than necessary for the washing or rinsing process, you also need to eliminate the cause.

The rarest reasons why the machine flashes

If the Indesit does not turn on, then it is worth considering even rare causes that can lead to a breakdown. They should be paid special attention to, because many people ignore them and as a result they cannot deal with the machine by themselves.

It is important to accurately determine the breakdown. It is necessary to check the following points:

    Unintentional water drainage, which leads to failure.

Once again, note that if the washing machine does not work, the indicators will certainly flash accordingly. That’s why you do not need to guess, just look at the indicators.

It is important to note that the heating element over the years can be covered with limescale. That is why its wear and tear increases significantly. The electric motor is able to break down for the reason that the condition of the brushes deteriorates significantly. Also, fur and hair could become wound up, which is especially characteristic of apartments where animals live. In this case, the control module can fail less often. Burned contacts can lead to such a situation, and such a situation is quite rare.

It is necessary to be guided by the Indesit instructions when checking the error codes. The most important thing is to accurately diagnose a breakdown, so that you can then carry out full repair work. If you identify the cause incorrectly, to fix the problem may require a lot of money. It is better to do everything right away, so that you don’t have to suffer later because of the problem.

Repair of indesit washing machine error h20

Error H20 indicates that the washing machine for a set time does not get the amount of water necessary for washing. The main types of causes are two. The first is when the water for objective reasons does not come into the machine: the water faucet is closed or even there is no water in the riser, or there is water pressure, but the screen of coarse water treatment is clogged which is located before the fill valve, or the fill valve itself is faulty washing machine.

On the photo is one of the most common types of filling valves. The second type of causes of error H20 is when the water into the machine, but at the same time out of it drains. As a rule, water goes down the drain, but we can assume that your washing machine has a serious leak? The main reason is trivial, the drain hose comes out of the bottom of the machine, lies on the floor and the point of entry of the drain hose into the sewer is also not high above the floor. In this way, there is nothing to prevent the water from going down the drain immediately after filling it up, thanks to the communicating vessel principle. To prevent this from happening, it is sufficient to fix the drain hose to the fixings provided for this purpose on the back of the washing machine, so that the highest point of fixing the hose is almost at the top of the machine. It is possible that with this attachment, the length of the drain hose is not long enough in order to properly fix it to the sewer, in this case you will need to extend it by buying a hose, adapter and two clamps.

Another possible option in this case is described in this article. Sometimes a faulty electronic control module can turn on the inlet valve and the drain pump at the same time.

Washing machine error code H20 | by Hotpoint

Deciphering and description of symptoms

Error h20 in the washing machine Ariston informs the user about the failure in the water intake system. If you read the number zero as the letter O, you get the formula for water. Manufacturers took this formula to make it easier to remember this error, which can occur with any program. In most cases, the washer hangs up before the rinse cycle.

See also  How to remove the tray in an indesit washing machine

The important peculiarity of error H20 consists in the fact, that if you start some modes “Drain” or “Spin”, the machine works normally, there is no error.

In addition, it is worth listing the symptoms that occur before the machine stops washing:

  • No water is poured into the tank at all;
  • too little water is coming in;
  • there is too much water in the tank;
  • water entering the tank is immediately discharged (self-drain).

Causes of appearance

Why does the system report this error? There are several reasons for this.

  • The main reason is related to the filling valve. Most often it is clogged with particles of debris and rust, which enter the machine with the water. Valve contacts or the valve itself may be faulty. Do not forget to check whether the water faucet is open and what is the pressure of the water in the water supply line. In this case you don’t have to look for a malfunction in the washing machine.
  • If self-draining water, the cause is the wrong connection of the drain hose to the sewer.
  • If there is little or a lot of water, then the cause should be sought in the fault of the pressostat.
  • The most common cause of error H20 is a faulty electronic module.

Pay attention if after error H20 code F01 appears, the error in the machine is more likely to be connected with the second error.

Fill valve

The problem with the fill valve is the main with this error, let’s describe it in more detail, let’s understand how to fix it. This part is located right behind the fill hose. Therefore, turn off the water and unscrew the fill hose, you will immediately see the strainer-filter of the fill valve. Carefully with a pair of pliers, pull out the mesh on itself, rinse in water. If the grid is rusty and very dirty, soak it in a solution of citric acid for 20 minutes, then rinse and return it to its place.

If it’s not a clog, move on to checking the part itself:

  • Remove the top cover of the washer-dryer to allow access to the unit;
  • Check the valve contacts using a multimeter;
  • Test the fill valve itself;
  • In case of a breakdown, disconnect the fill valve from the electrical,
  • Unscrew it from the housing;
  • Install a new part.

Pressostat and drain system

The water level sensor “monitors” the water in the washing machine, which signals to the module how much water has been drawn. If the sensor is faulty, too much or too little water may be flowing into the tank. Check this part yourself is not difficult. You will need to:

  • Remove the top cover from your Ariston washing machine.
  • Find the pressostat on top of the machine.
  • Check the tightness of the pressure tube connection. It could be loose or clogged, which will definitely affect the operation of the part. In addition, the tube may have burst, in which case it must be replaced.
  • Next, using a multimeter, check the sensor contacts and wires going to the pressostat.
  • If all of the above elements are intact, then most likely the sensor itself is broken, which is not very common.
  • Take a similar part on the washing machine Ariston and install in place of the faulty.

In the case of a self-draining water drain, immediately start checking the drain hose. If the drain point is below the allowable, then the water will start to flow out of the tank. This can happen if you initially incorrectly connect the washing machine to the drain, as well as in the case where the drain hose fell out of the latch on the back wall, which held it in an upright position. All about the drainage system and connection, read the article How to make a drain for a washing machine.

error, washing, machine

Electronic board

If after checking the valve and pressostat, the machine still displays an error, then it is worth thinking about the control board. Mainly a burned out triac or a track that controls the water inlet valve can be the cause. In this case, there is a chance to repair the module. You need a new element, a soldering iron and patience. However, in most cases, we recommend to entrust this work to a master. Don’t think we’re trying to talk you out of it.

In the rarest cases, the washing machine Ariston may freeze due to a failure in the firmware of the electronic board. Try to disconnect the equipment from the network for about 20 minutes and then restart the washing, maybe a reset of “brain” will help to solve the problem. Otherwise you have to re-flash or replace the board with a new one, which will cost a lot of money.

Thus, error H20 can lead you to the failure of various nodes. But in most cases the problem is solved on the spot, that is at home. You can do the repair yourself, following the instructions, but if you don’t want to do it, call a technician. Good luck!

  • 09.11.2017 at 22:30 Andrew: If the machine pours the water, then gives an error H2O, and begins to drain, then after drain stand a little and then begins to fill again, and so on to infinity? At the same time with flashing error H2O rinse, spin, drain in manual mode works. I understand it is the pressostat that needs to be checked?
  • 21.12.2017 at 20:54 Alexei: Ariston 605 takes on water (the truth in my opinion not enough water) washed in all modes 12-13 minutes. After that the error h20 came on. What’s the reason?
  • 16.05.2018 at 15:19 Sanja: The machine did not draw water at all, it immediately seemed that it was at the software level. But in the end cleaning the valve helped, it looked clogged and not so bad. Thanks.
  • 04.04.2020 at 11:58 Eugene: I just had the same error, on the cycle poured, drained about two hours. Lowered the drain hose. Immediately the water was filled to the end and continued washing.

Signs of error H20

Error h20 washing machine “Ariston” or “Indesit” appears most often. It appears about five minutes after the washing has started. And, the program can be any. In this case, the washing machine:

  • The liquid does not accumulate at all;
  • It takes a small amount of liquid, which will not be enough for washing;
  • Too much water is being drawn in;
  • Too much water; Too much liquid constantly comes in and goes out;
  • In some cases, the machine may stop during the rinse process, the spinning does not occur.

Important! It is possible chaotic appearance and disappearance of error h20 in different programs. But if you start the drain or wring separately, they work as they should without failure. If the error h20 in the washing machine “Indesit” or “Ariston” appears first, and after it displays another code, most likely the cause of the failure is the second error.

Call a master

In those cases when it is impossible to correct the faulty situation on your own, you should contact a company engaged in repair of Indesit washing machines. You can find a company on the Internet by searching for your city.

Many companies indicate the for the work right on their website. Also there is contact information, which allows you to contact the dispatcher service and make a request for a call to the masters.

  • replacement of the filling valve. from 1 500;
  • Pressostat cleaning/replacement. from 1 600;
  • electric circuit repair. from 1 500;
  • control board repair. 2,000 or more and t.д.

After the repair is completed, the technician tests the performance of the washing machine and gives a warranty on the work performed.
