The tap in the Bosch dishwasher is on

For what reasons does the “faucet” on the panel light up or blink?

In the article “Dishwasher Indicators and Icons,” we described their meaning in detail.

If the “faucet” light on the control panel comes on (next to the water supply button), and the dishwasher is working normally, everything is fine. This means that water for washing has begun to flow into the car.
If you notice that the water supply indicator is on or flashing, while the machine beeps, and water does not enter the hopper, there are problems.

The explanation of this problem in the instructions sounds like this: there is no water supply. What could be the reason:

The inlet filter is clogged.
There were problems with the fill valve (broken, clogged).
Incorrect connection of the drain system. Self-draining occurs.
The water sprayer in the chamber is faulty.

All of the above signs may be indicated by code E15. If error E15 is on the PMM display and a tap is shown, there may be a problem with the Aquastop leak protection.

In various models of Bosch dishwashers, it can be full or partial.

Due to the leak, water enters the pan of the machine. With full protection, there is a float sensor that is triggered. As a result, a fault code is displayed on the display.

When the protection is partial, there is an absorbent sponge in the inlet hose. As soon as a leak occurs, the sponge is saturated with water and blocks access to the system. Read more about “Aquastop” for the dishwasher in a separate article.

Important! A large amount of foam can lead to leakage and tripping. Control the amount of detergent.

The faucet indicator on the Bosch dishwasher is on or blinking, what should I do?

Don’t immediately panic and rush to call the service center technicians.

If the indicator lights up brightly and the dishwasher is functioning normally, water has begun to fill.
If the operation of the equipment has stopped, characteristic sound signals in the form of a squeak are heard, the indicator lights up brightly or flashes - specialist intervention is necessary.

The “faucet” is located next to the water supply button. When the light signal goes off, it means there is a problem with the water supply. This malfunction may occur due to:

intake valve clogged;
failure of the filling valve (clogged, broken, etc.);
incorrect connection of the drainage system
Leakage in the dishwasher tray.

The error code displayed on the dashboard – E15 – can also indicate the above problems. The code and flashing indicator can warn the owner of household appliances about problems that have arisen in the Aquastop leakage protection system. If there is a leak in the system, water flows into the pan. The float sensor gives a signal to the system and an error code appears on the display.

You can try to fix the problem yourself, but this will require certain knowledge and skills. Wrong actions can only make the problem worse.

Water in the pan. Unplug the dishwasher. Tilt the body of the equipment so that the float is in its normal position. Drain the water from the pan. Leave the equipment for a while so that the accumulated moisture can dry out.
Problems with water supply. turn off the water supply. To do this, you will need to close the fill valve. Check the filters in the system for blockages. Check the inlet hose for kinks and blockages. If necessary, disconnect it from the system and wash it with water. Check the inlet valve.
Spray. Open the container door and remove the trays. Remove the upper and lower spray arms and wash them.
Leak sensor. A faulty sensor may provide the system with incorrect data and the control module does not start flooding. The failed sensor will need to be replaced.
Self-draining In the Norm, the drain hose is located from the floor at a level of 45 cm. Compliance with this standard and the correct bending of the hose will minimize the risk of self-draining water into the sewer during flooding.

How to troubleshoot a Bosch dishwasher

Start by checking “Aquastop” - it happens that the sensor simply sticks in the pan. Inspect the housing and hose connections for leaks. If everything is ok, do this:

Pull out the PMM plug from the socket.
Tilt the equipment from side to side until the float returns to its normal position.
Drain any water that has entered the pan.
Let the car dry.

Also inspect the hose. If you are convinced that the mechanical protection has activated, the inlet hose must be completely replaced.

Water supply problems

The error sign has disappeared, but the faucet is still on? Then you need to check the filling system.

Shut off the water supply by turning the inlet valve.
If you installed an in-line filter, remove it and check for blockages.
Disconnect the inlet hose from the housing. Rinse it under running water.
Take out the filter mesh. It often becomes clogged with rust and scale. If dirt cannot be removed with plain water, place the filter in a solution of water and citric acid.

The last thing to check is the intake valve. In Bosch dishwashers it is often located in the lower part of the housing.

Unscrew the fastening screws and remove the decorative panel from below - there is a valve behind it. Disconnect the wiring connectors.

Checking the electronic part of the valve is done with a multimeter. Connect its probes to the contacts of the part and measure the resistance. The working device should show from 500 to 1500 Ohms.

To check the mechanical part, apply operating voltage (220 V) to the valve and see whether the membrane opens or not. In case of any malfunctions, the element must be replaced. Unscrew the fastening screw, remove the old part and install the new one.

When purchasing an inlet hose, make sure that the markings match the old model. Otherwise, you may select an inappropriate element.

Additionally check the nozzles:

Open the hopper door.
Pull out the baskets.
Remove the upper and lower spray arms from their place.
Rinse under the tap. The injectors can be cleaned with a toothpick.

Sometimes the cause of such problems can be a leakage sensor. It may have failed or is sending incorrect signals to the module. Then you need to carry out diagnostics and, if necessary, replace the sensor.

Self-draining

Is the faucet indicator flashing? Then check that the dishwasher is connected to the drain correctly:

The drain hose should be located at a distance of 45 cm from the floor.
It is necessary to create the correct bend to avoid self-draining into the sewer.

The control board recognizes the problem as insufficient water level in the tank. That is, in the allotted time the machine was unable to collect enough water. How to properly connect a dishwasher, read a separate article. Monitor and care for your equipment. Read about how to clean your dishwasher.

Most users prefer to use a dishwasher without worrying about indicator symbols. Errors and other subtleties. As long as the dishwasher works properly and performs its function.

Bosch dishwashers are equipped with a self-diagnosis system. If any problems or deviations in operation are detected. Lights or errors may appear on the dishwasher display. One of these indicators. Faucet icon.

Let's note right away. Which depends on the error and generation of the Bosch dishwasher. The faucet indicator may either light up or flash. If there is a digital display. The faucet may flash, and a malfunction error will appear on the digital display.

Causes of faucet fires

This problem is given little attention in the user manual, so we decided to devote this section of our website to a detailed study of all the important points related to the occurrence of the error.

According to the instructions, the decoding is as follows: “Tap” lights up (or blinks) if water intake is not fully ensured. The explanation is too sparse, without even explaining the user’s actions in this case, right? But you need not only to diagnose the breakdown, but also to fix it. We list the breakdowns that activate the indicator on the PMM control panel:

The filter located at the inlet valve is clogged.
The filler valve is broken.
The drain hose is connected incorrectly, which causes back drainage.
The AquaStop leakage protection system has activated.

If you have problems recognizing icons and codes in a Bosch dishwasher, read a separate article with a breakdown of the symbols.

In all of the above situations, the water supply indicator may behave differently:

if the inlet filter is clogged and the liquid does not penetrate into the device or enters there slowly enough, the light may light and flash;
if the intake valve does not operate, then the sign simply lights up;
if self-draining occurs, the faucet blinks;
The light bulb behaves in approximately the same way if “Aqua Stop” is activated.

Reasons for error E 24 in a Bosch dishwasher

The E24 icon on the display can appear due to both minor failures and serious malfunctions. Most often the problem is caused by:

clogged filters - if the system is clogged with debris and grease, the water drains too slowly or stops altogether, and the dishwasher gives an error;
twisting of the drain hose; when using the machine for a long time, it can break or bend in some places, which impairs the quality of liquid drainage;
the pump is clogged, deposits can accumulate on the impeller blades, and hair often gets wrapped around it;
electronic failure, even if the dishwasher is in full working order, its control unit may produce random errors.

Error E24 is an indicator of problems with drainage. Important! In rare cases, error E24 appears in a Bosch dishwasher due to complete failure of the electronic system. But before you send the unit for service, in any case, you can try to fix it yourself.

Water supply problems

If the error code sign has disappeared on the display, but the “faucet” is still on, you need to make sure that the filling system is working properly.

Close the inlet valve, first turning off the water supply;
If a flow filter is installed on the device, remove and clean it from dirt;
Detach the inlet hose from the dishwasher body. Rinse the blockage with running water;
Remove the mesh filter; it becomes clogged with scale and becomes rusty. Contaminants can be removed using a solution of water and citric acid;
Don't forget to check the intake valve. In Bosch dishwashers it is located at the bottom of the housing. You should unscrew the fastening screws and remove the decorative panel from below, you will find the valve there. Disconnect the wiring connectors.
In order to make sure that the electronic part of the valve is working properly, you need to use a multimeter. Take its probes and connect them to the contacts of the part, so you will find out its resistance. It should be from 500 to 1500 Ohms.

The mechanical part of the drain hose may also become unusable. Its condition can be checked by applying power from the electrical network to the valve, after which the membrane should open. If you find any malfunction, the part should be replaced with a new one. When purchasing a new part, check the markings with the previous sample.

The problem with water supply may also include the following nuances:

sprayers. They may be dirty. To clean them, remove the hopper door, pull out the baskets, and disconnect the upper and lower sprinklers. The injectors are cleaned with a toothpick.
leakage sensor. Failure of this part or transmission of incorrect signals to the control module can lead to problems with water supply. In this case, it is necessary to diagnose and replace the sensor.
