Error E40 in the Electrolux washing machine

If the Electrolux washing machine does not start washing and a few seconds after turning off it displays error E40, then you need to urgently look for the reason. Otherwise, the machine will not turn on. We will tell you in detail why error E40 appears in an Electrolux washing machine and how to fix it.

Explanation of the error and its causes

Error E40 is a common error that is caused by a breakdown of the door locking device. This error can be clarified by entering the control board diagnostic mode. On washing machines without a software selector, this can be done as follows:

1. Simultaneously press the two buttons on the right, indicated by number 1 in the figure below.
2. Turn on the machine by pressing the button number 2, continuing to hold the buttons until all the indicators flash.

For your information! On washing machines with a program selector, to enter the diagnostic mode you need to hold down the two buttons on the far right.

After entering test mode, error code E40 will disappear and one of the following codes will appear:

• E41 - informs that the hatch door is not tightly closed;
• E42 - indicates a breakdown of the hatch locking device;
• E43 – the triac responsible for the UBL is faulty;
• E44 – drum door opening sensor is broken;
• E45 - the electrical circuit between the triac and the UBL is faulty.

Replacing the door lock

So, if the washing machine produces error E40, do not rush to enter test mode. Try to press the hatch door tighter by gently pressing it with your knee. If this does not help, then you will have to clarify the error as described above or manually check all possible causes of this malfunction one by one.

Start with the hatch locking device, namely the lock, you need:

• remove the clamp from the rubber cuff;
• Unscrew the bolts holding the lock in the machine body;
• remove the lock from the space between the tank and the front wall of the housing;
• check contacts;
  

  Important! Contacts 3 and 4 should be closed, and contacts 4 and 5 should be open.

• disconnect the lock from the wires and install a new one;
• return the lock and clamp to their place;
• run a test wash.

Other faults

Sometimes the cause of the breakdown is a malfunction of the electrical wires between the control board and the door lock system. In order to detect a damaged wire, take a multimeter and ring each of them in turn.

It is much more difficult to repair the control board on which the door lock control triac is located. To find this triac, you need to have a good understanding of electronic circuits. In addition, in the event of a malfunction, you will have to resolder the part, and this also requires certain skills and dexterity.

The figure below shows an example of an EWM200 control board. At the bottom right is a triac, which affects the operation of the lock. Perhaps this will help you solve the problem. But, if you have never encountered such work, contact a specialist who will do everything correctly and quickly.

Keep in mind that the appearance of error E40 can be simultaneously caused by a burnout of the triac on the controller and a breakdown of the lock. Therefore, you will have to check everything related to the door closing and opening system. You will learn about other typical breakdowns of this equipment from the article Electrolux washing machine repair. Good luck!
