Bosch dishwasher error codes: decoding

Many dishwashers have a self-diagnostic function. It not only detects errors in the operation of the machine, but also displays them in the form of codes, and in some cases turns off the dishwasher. Bosch dishwasher errors are displayed by codes consisting of the letters E or F along with numbers. Let's take a closer look at the error codes that light up on the screen and their decoding.

Bosch dishwashers

For many buyers, the criterion for choosing a reliable dishwasher is the country of manufacture and brand. Models from the German company Bosch come first on this list. And this is no coincidence. Their reliability is assessed by consumers according to the following indicators:

1. Bosch build quality.

The German company Bosch has long been considered a world leader in the production of household appliances. All its products are of high quality, in addition, they are convenient and practical.

German-assembled dishwashers are in demand not only in Germany, but also in other countries, including Russia. It is difficult to argue with German quality, because with proper use the models last for decades.

2. Quality of components.

Most components are made from reliable materials. For example, Bosch uses stainless steel to make dish baskets. The filter and sprinkler are also made of metal.

3. Contacting service centers.

Statistics from service centers for the repair of household appliances show that only 6% of calls are related to breakdowns of Bosch dishwashers.

Starting a test cycle

Bosch dishwashers have a test mode that can be run as a troubleshooting measure.
The method to run this test process is similar across the Bosch range, so if your machine's functions seem to differ from those described below, it's worth experimenting as the process is similar with only minor differences. To start the test mode, hold down the POWER SCRUB PLUS and REGULAR WASH buttons. Holding down the ON/OFF button may also help. The indicator above them should blink.

You can now check the status of each program by clicking a button, or you can run a full testing period.

Press the Power SCRUB PLUS and REGULAR WASH buttons. The electronic device will start and when the selected mode has ended, if you do not have a display, the indicator on your dishwasher model will light up if a fault has been detected.

Bosch dishwasher heating error codes

Possible errors in Bosch dishwashers related to heating are reflected in the following block of codes:

1. Code E01 (F01) - lights up on the screen if the heating element (heating element) malfunctions, or if its circuit is broken. It is possible that the electronic module of the element that controls the heating element may fail.

How to fix the error:

• The heating element is checked. Zero resistance or a breakdown to the housing may be detected. The heating element cannot be repaired, but is completely replaced;
• the safety thermostat is checked;
• The temperature sensor is checked.

2. Code E2 (F2) - appears on the display in case of malfunction of the sensor that controls the water temperature. This error usually alternates with code E01 (F01). The temperature sensor should turn off the heating element after heating the water. In the event that it fails, the heating element overheats the water.

How to fix the error:

• the resistance of the sensor is measured at the contacts;
• if the resistance value is low, the sensor must be replaced.

3. Code E09 (F09) - lights up on the screen in case of malfunction of the flow heater built into the circulation pump.

How to fix the error:

• The device checks for breakage of the heating element;
• at zero resistance the heating element changes.

4. Code E11 (F11) - appears on the display if the heater is turned off. As a rule, in this case, the control signal does not arrive at the temperature sensor, or there is no supply voltage to the sensor.

To identify and eliminate errors, check:

• internal resistance of the temperature sensor;
• internal resistance of the control module;
• condition of the temperature sensor wiring.

5. Code E12 (F12) - lights up on the screen if there is an increase in scale or dirt on the heating element.

How to fix the error:

• The condition of the heating element is checked. If after a reboot the code E09 (F09) is displayed, then there is a lot of scale;
• the heating element is removed, cleaned and reinstalled.

How to check the pump:

• Disconnect the device from the network and communications.
• Lay a towel on the floor.
• Turn the PMM body over on its side.
• Remove the bottom panel.
• In Bosch dishwashers, the pump is assembled with a heating block.

To identify and eliminate the error, check:

• presence of water in the water supply;
• inlet filter condition;
• serviceability of the intake valve;
• the serviceability of the sensor that determines the water level.

If the above checks do not produce results, then the functionality of the pump is checked.

2. Code E5 (F5) - appears on the display when the tank is overfilled with water. First of all, this is due to the operation of the sensor that determines the water level.

To identify and eliminate errors, check:

• condition of the sensor tube for the absence of dirt;
• serviceability of contacts and supply wires of the sensor;
• the fill valve is in good working order to ensure there is no blockage due to which the water is not completely shut off.

3. Code E8 (F8) - appears on the display when the water level in the pan is low. If there is a lack of water, the circulation pump stops.

To eliminate the error, use the E3 (F3) code recommendations described earlier.

4. Code E16 (F16) - lights up on the screen when the tank is filled with water unauthorized. Most often this is due to a malfunction of the intake valve. For example, there is a blockage with debris, so it does not completely block the flow of water.

To identify and eliminate the error, check:

• intake valve condition;
• serviceability of the sensor that determines the water level;
• no increased amount of cleaning foam.

5. Code E17 (F17) - appears on the display if there are problems with water supply. First of all, this is due to increased water pressure in the water supply. In this case, the normal operation of the valve that admits water is disrupted.

How to fix the error:

• if the increase in pressure is due to water hammer, then the dishwasher simply reboots;
• The water pressure level at the machine inlet is checked. The pressure is reduced by the valve on the riser;
• The functionality of the flow sensor is checked.

4. Code E21 (F21) - lights up on the screen when the drain pump stops. In this case, control commands are sent to it, but there is no drain.

Main causes of typical malfunctions

Even such reliable equipment as Bosch can fail for completely banal, everyday reasons, for example, due to loading excessively dirty dishes into the washing chamber. Residues of food washed away by the flow of water will clog the filter and cause clogging.

If the loaded dishes are too dirty and greasy, the unit will not be able to rinse them efficiently, and the housewife will have to additionally rinse the plates and cups by hand

To avoid this situation, it is better to first clean the food left on the plates before placing them in the machine.

An incorrect connection to the electrical network and a faulty socket have a bad effect on the dishwasher. A drain hose that is too long or poorly secured in the water supply area can also create problems, so installation and installation should be entrusted to professionals.

If the home master wants to do this himself, it is necessary to strictly follow the installation instructions and strictly comply with the requirements prescribed by the manufacturer in the passport supplied with the unit.

Dishwasher detergent must have a normal shelf life. It is recommended to buy it in a specialized store where the rules for storing household chemicals are observed.

A lot of inconveniences, and subsequently problems, are caused by improper loading of dishes into the washing chamber. Many users do not pay attention to this point and then encounter various problems.

In order for the washing process to proceed normally, the dishes in the sections must be placed compactly. Then it will not interfere with the rotation of the irrigation rockers, the timely opening of the dispenser, the free passage and uniform flow of water

Before loading plates, cups and cutlery, you must carefully study the instructions for loading dishes and take into account all the wishes put forward by the manufacturer of the equipment.

Dishes placed correctly will be perfectly washed and will not require any additional action from the housewife. In this case, the machine will not feel overload and will serve well throughout the entire operational period.

We recommend that you familiarize yourself with the operating instructions for your Bosch dishwasher in order to avoid problems in the future due to their violation.

In general, it should be noted that self-monitoring significantly increases the reliability of the Bosch dishwasher. Simple breakdowns can easily be fixed on your own after deciphering the codes. But in case of serious damage, it is better to contact specialists.

There is a current leak

When a machine gives an electric shock, it is extremely dangerous for all the inhabitants of the apartment and the first signal is that somewhere inside there is broken wiring insulation or there is a malfunction of the heating device. Therefore, a short circuit to the housing occurs - a thorough check of the entire electrical system is necessary. We have already written about how to ring an element; at the same time, you need to check all the wiring and other electrical components in the same way.

Do-it-yourself repair of Bosch dishwashers will cost users much less than calling a service center specialist, which costs from 500 to 1.5 thousand rubles.

Statistics say that Bosch machines occupy a strong leading position in the world in terms of repair costs, and spare parts have astronomical prices. By doing all the work yourself, you can save a decent amount and spend it on something more pleasant in all respects. And this video will help you do everything right.
