Error E57 in a Bosch washing machine

Code E57 may appear on the display of modern Bosch washing machines equipped with an inverter engine. This error indicates a problem with the direct drive. The problem should be resolved immediately. Let's figure out what is hidden behind this code and how to return the machine to its previous performance.

Origin of the cipher

What should you do if you notice this code on the “home assistant” display? Find out the cause and eliminate it as soon as possible. Error E57 on a typewriter Bosch informs you about the failure of the inverter motor components. But what can cause damage to the motor?

The cause of the failure is usually trivial voltage drops. You may not notice them, from the outside everything looks quite harmless: the indication on the control panel goes out slightly, and after a second lights up brightly again. However, even short-term interruptions in the power supply have a strong impact on the electronics of the washing machine. After one or several such jumps, individual electronic units burn out and the machine stops working.

Most washing machines are not equipped with a built-in surge protection system, so their electronics are quite vulnerable.

If in European countries there is no need for a stabilizer, then in Russian houses voltage drops are a common phenomenon. Even a momentary power failure can lead to problems with the inverter motor.

Error code E57 may indicate the following problems with the inverter:

• failure of the power module;
• “burning out” of the inverter module;
• weakening of contacts between them.

To fix the machine, you will have to check all the weak points of the inverter engine.It is not necessary to call a specialist; you can try to deal with the breakdown yourself. Let's look at how a Bosch washing machine is repaired in this case.

“Calling” the power and inverter modules

What to do first? Of course, unplug the machine and close the shut-off valve. If error E57 occurs, you will have to “ring” the power and inverter modules using a multimeter. It is recommended to start with the latter, it is considered more vulnerable.

The algorithm of actions will be as follows:

• remove the top and rear panels to gain easy access to the direct drive system;
• find the inverter module. It is a board, chips with contacts are connected to it;
• take a photo of the wiring diagram;
• remove the element from the housing.

Then you need to arm yourself with a multimeter and check the power circuit with the device. In half of the cases, the cause of the problem is a burnt-out starting resistor, so it is recommended to start there. If it really doesn't work, you'll have to replace the element. This is ten times cheaper than purchasing a new module entirely.

By following the instructions, you can replace the starting resistor yourself. You just need to make sure that it is faulty, remove and solder a new element. However, for people who have never worked with electronics, it is better not to take risks, but to entrust the repair to specialists.

Getting rid of code

When the cause of the error is eliminated, it will not be possible to immediately start the automatic machine. After repairing or replacing the inverter module, all that remains is to reset the fault code by rebooting the intelligence. You should turn on the washing machine, wait until E57 is displayed on the screen, and do the following:

• put the selector knob in its original position (Off);
• switch to “Spin”;
• hold down the “Drum Speed” button (located on the control panel) and at the same time switch the programmer to the “Drain” mode;
• count to 3 and release the “Drum revolutions” key;
• sharply turn the selector to the “Super Fast 15” program;
• wait a couple of seconds and turn off the washing machine.

After these steps, the “brain” of the machine will forget about the malfunction and launch the washing program you have chosen without any problems. You may not be able to reset the error code the first time. Repeat the manipulations following the instructions provided.

   Andrey:

   Hello!
   On the Bosch WVH 284420E Series 6 EcoSilenceDrive washer-dryer I can’t find anywhere how to reset the error. Help me please!
   It throws error e58, e78!
