Error E40 in the washing machine Electrolux

If the Electrolux washing machine does not start washing and a few seconds after shutting down gives an E40 error, then you need to urgently look for the cause. Otherwise, the machine will not turn on. Why does the e40 error appear in the Electrolux washing machine and how to fix it, we will tell you in detail.

Deciphering the error and its causes

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

1. Press the two buttons on the right at the same time, indicated by the number 1 in the figure below.
2. Turn on the machine by pressing the button under the number 2, while continuing to hold the buttons until all indicators blink.

Note! On washing machines with a program selector, to enter the diagnostic mode, you need to hold two extremely buttons on the right.

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

• E41 - informs that the hatch door is closed leaky;
• E42 - indicates a breakdown of the hatch lock device;
• E43 - faulty triac responsible for UBL;
• E44 - the sensor for opening the drum door is broken;
• E45 - a faulty electrical circuit between the triac and UBL.

Door Lock Replacement

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

Start with a hatch lock device, namely with a 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! 3 and 4 contacts should be closed, and 4 and 5 contacts should be open.

• disconnect the lock from the wires and put a new one;
• return the lock and clamp to the place;
• start test wash.

Other malfunctions

Sometimes the cause of the breakdown becomes 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 alternately ring each of them.

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 be well versed in electronic circuits. In addition, in the event of a malfunction, you will have to re-solder the part, and these are also certain skills and dexterity.

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

Keep in mind that the appearance of the E40 error can be simultaneously caused by the burnout of the triac on the controller and the breakage of the lock. Therefore, you will have to check everything related to the system of closing and opening the door. You will learn about other typical breakdowns of this technique from the article.
