Error E57 in a Bosch washing machine

The E57 code may appear on the display of modern Bosch washing machines equipped with an inverter motor. This error indicates a problem with the direct drive. This issue should be addressed immediately. Let's explore what this code means and how to restore your machine to its previous functionality.

Origin of the cipher

What should you do if you see this code on your home assistant's display? Determine the cause and fix it as soon as possible. Error E57 on a typewriter Bosch reports a failure of inverter motor components. But what can cause damage to the motor?

The cause of failure is usually simple power surges. They can go unnoticed, and from the outside, they appear harmless: the control panel indicator dims slightly, then brightens again a second later. However, even brief power outages have a significant impact on the washing machine's electronics. After one or more such surges, individual electronic components burn out, and the machine stops working.

Most washing machines do not have built-in surge protection, so their electronics are quite vulnerable.

While stabilizers are not necessary in European countries, power surges are common in Russian homes. Even a momentary power outage can cause problems with an inverter motor.

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

• failure of the power module;
• "burnout" of the inverter module;
• weakening of contacts between them.

To repair the machine, you'll need to check all the weak points of the inverter motor. You don't necessarily need to call a technician; you can try to fix the problem yourself. Let's look at how to repair a Bosch washing machine in this case.

We are calling the power and inverter modules

What should you do first? Naturally, unplug the machine and turn off the shutoff valve. If the E57 error occurs, you'll need to use a multimeter to test the power and inverter modules. It's recommended to start with the latter, as it's considered more vulnerable.

The algorithm of actions will be as follows:

• Remove the top and rear panels to gain clear access to the direct drive system;
• Find the inverter module. It's a board with connectors attached to it;
• take a photo of the wiring diagram;
• remove the element from the housing.

Next, you need to grab a multimeter and check the power supply circuit. In half the cases, the cause of the problem is a burned-out starting resistor, so it's recommended to start with that. If it's truly faulty, you'll have to replace the element. This is tens of times cheaper than buying a new module entirely.

By following the instructions, you can replace the starting resistor yourself. You just need to make sure it's faulty, remove it, and solder a new one. However, if you're new to electronics, it's best to avoid taking risks and entrust the repair to professionals.

Getting rid of code

Once the cause of the error has been eliminated, it will not be possible to start the automatic machine immediately. 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 appears on the screen, and do the following:

• return the selector handle to 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 Speed" 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 machine's "brain" will forget about the malfunction and run your selected wash program without any problems. You may not be able to reset the error code the first time. Repeat the steps, following the instructions provided.

   Andrey:

   Hello!
   I can't find a way to reset the error on my Bosch WVH 284420E Series 6 EcoSilenceDrive washer-dryer. Please help!
   It throws error e58, e78!
