Bosch dishwasher errors: how to fix

The heater contacts are out of order, or the heating element is burned out. If this is confirmed as a result of the check, the heating element must be changed.

Check the temperature sensor together with the heater.

The error may alternate with the previous one.

E2 means a breakdown of the temperature sensor. A failure causes the heater to work poorly because the thermistor does not report water temperature information.

To confirm the breakdown, check the contacts of the temperature sensor with a tester. If the resistance is about 50 kOhm – the element is working, if there are deviations, it needs to be replaced.

Fault codes E09 or F09 report problems with the flow heater. The E09 code appears in those PMMs in which the heating element is located in the circulation pump.

To eliminate the breakdown, replace the heating element. Before making repairs, check the part with a tester.

What does the code E11 mean? He reports that the dishwasher’s temperature sensor is not powered. Second value: the circuit between the electronic board and the temperature sensor is broken.

An error can be caused by a “wagon” of factors, so the following need to be checked: the contacts of the temperature sensor, the wiring between the sensor and the board.

The code is typical for Bosch dishwashers, in which hard water has accumulated on the heater.

If you rebooted the machine, and E12 appeared after the E09 code, it’s a matter of scale. Sometimes you can do without replacing parts – you need to remove and clean the heating element.

With code E3, the dishwasher stops working because the selected program did not draw enough water in the allotted time. At F3, water is automatically drained from the system.

If your dishwasher is more than 7-10 years old, its behavior may be different: the machine will give an error and wait until the required amount of water is collected.

Need to check:

Is there water in the tap?

Whether there is a blockage in the filter on the intake hose and at its inlet to the machine;

Is the water inlet valve working?

What is the condition of the level sensor?

Is the drain pump running?

Breakdown codes indicate that the Bosch PMM tank is completely filled. This happens if the machine takes on excess water, and the level sensor fails to control and stop the process.

The reason is the sensor. Check needed:

· his tubes for blockage;

contacts and wiring element;

filling valve (maybe it does not close completely, which is why water flows into the system without stopping);

control system (a rare case, the verification of which is better to entrust the master).

These codes are displayed when the dishwasher does not block the access of water to the tank – it begins to flow in an uncontrolled amount. The failure is caused by a clogged intake valve.

Looking for:

· checking and cleaning the valve;

checking the level sensor;

Checking if there is excessive foam from the detergent (in the case when an error occurs during the operation of the machine).

Combinations E17 or F17 are displayed on the dishwasher display when there is a problem with water filling. Very “narrow” error – means that the valve closes with difficulty or its overlap is completely blocked.

If water hammer is to blame for the failure, then a reboot will help. And if there is constantly increased pressure in the water supply system, a partial shutoff of the water in the riser is required. At the same time, check the level sensor.

These codes indicate problems with the drain pump when it does not pump water. It is relevant if there is no break in the power circuit, and the pump interacts with all sensors and the board, but does not work.

Reasons for failure:

The impeller of the pump is jammed due to blockage or debris wrapped around it;

the rotor sticks to the bushing wall – in this case, in addition to E21, the code E22 is likely;

The pump is worn out and needs to be replaced.

In most cases, the cause of the error is a blockage in the drain pump nozzle (near the base). The pump cannot push water into the drain, the sensors report this to the board, and it blocks the operation of the machine and issues the E25 code.

Cleaning the pipe and the water drain hose, checking the impeller will help.

The error is typical for modern models with the AquaStop system, it appears when a leak occurs. To eliminate the code, inspect the pan and hoses, make sure there is a leak.

If you do not find traces, inspect other elements of the system.

Code E01 indicates problems with the electrical or electronic component of the device. Before restarting the machine, make sure that the display shows E01 and not another code.

Did the repeated reboot help? Turn off the machine and contact the service.
