Why is the light on?
If you find that the Bosch dishwasher panel indicator with the tap symbol lights up, but the dishwasher is working in the usual mode, it means that water has started to flow into the machine, and the alarm is false. If the dishwasher is making weird squeaking noises when the indicator light is flashing, but there’s no water in the hopper, it means the part is out of order or there’s a malfunction.
It is worth understanding that the sign “tap” means no water supply, the cause of such behavior may be the following factors:
- clogged intake filter;
- The inlet valve malfunctions because it is broken or clogged;
- Incorrect connection of the drainage system, which causes it to occur on its own;
- the water dispenser is malfunctioning.
All these signs of failure of the washing machine “Bosch” fit into a short error code E15. In addition, the faucet can mean a failure in the leak protection mode “Aquastop”. It is often the case that you are responsible for a leakage and the leakage protection kicks in. It is important to control the amount of detergent you add to the socket.
Depending on the model “Bosch” leak protection can be full or partial. The tray of the machine is filled, and the sensor, which controls the water level, is triggered. As a result, you see an error code on the display. If the protection is partial, when a large amount of water is formed, the absorbent sponge becomes saturated with liquid and closes the access.
Variety of errors on devices without digital display
This type of errors is not standardized, so this section will look at some options for displaying them on different panels. In order to know the way to eliminate them, at the end will be given a numerical code (for example, E4), which will be deciphered in the following section. Remember, don’t forget to put your Bosch dishwasher into service mode.
Panel, which will display up to three digits:
- – no problem;
- 1. faulty water supply indicator (E6);
- 2. error in the water heating system (E01);
- 4. tank not filled (E3);
- 8. broken thermometer (E2);
- 16. faulty flow regulator (E4).
- S3. no problem detected;
- A or B. error of receiving data from aqua-sensor (E6);
- E. no signal from the flow switch (E4);
- F. water is not entering the working cavity (E3);
- G. flow switch does not stop (E5);
- H. there is a problem with the heating element (E01);
- K. short circuit or faulty wiring (E2).
Dishwasher choice: types, functions, modes
Dishwashing is a messy business. luckily, the dishwashing function has long been taken over by automatic dishwashing machines. The only thing left to do is to make the right choice of dishwasher. and you can forget about washing up by hand for good.

There are many factors to consider when choosing a dishwasher. Not just the size, but also the functions and modes of dishwashers.
Dishwasher types
The main parameter, by which dishwashers are compared, is the number of “sets of dishes” the machine cleans in one cycle. A “set” includes three plates, as many spoons, a knife, fork and cup and saucer. Of course, this concept is relative, and is used precisely in order to be able to compare the performance of different dishwashers.
According to dimensions the division is carried out into:
The first type is the most compact. Its width and length are no more than 55 cm, and its height is 45 cm. It can be placed on the table or hidden under the sink if there is not enough space for a large dishwasher. Such variant is suitable for a small family, as it cleans not more than five sets of dishes in one cycle.
