When such a signal appears on the CMA display before the washing process begins, the machine does not perform any operations - no water is drawn in, the drum does not rotate. Error E40 on an Electrolux washing machine usually appears after closing the loading hatch and activating the program. In this case, you should not despair; failure may occur for simple reasons, which can be eliminated within a few minutes.
Let's not hide the fact that sometimes you have to tinker much longer. If all attempts to reset error E40 were unsuccessful and the machine did not return to working condition, we recommend inviting an experienced specialist to help.
Meaning of error code E40
In each model Electrolux washing machine A letter and number combination such as E40 indicates problems with the loading door lock. The code has a general concept. To specify the culprit of the malfunction, you should enter the mode. The master copes with this task perfectly, but the general algorithm of actions looks like this:
- simultaneously press two buttons located on the right side of the control panel;
- While continuing to hold them, you need to press the large orange button located on the side. Continue pressing until the indicator lights light up.
Ultimately, the screen will display the updated fault code E40:
- E41 – loading hatch is not closed tightly enough;
- E42 – lock failed;
- E43 – the part responsible for blocking has broken in the control module;
- E44 – door sensor malfunction;
- E45 – problems have arisen in the wiring connecting the UBL and the control unit.
When is it possible to resolve error E40 on your own?
We found out what error E40 means. It remains to figure out how to fix the problem that has appeared.
If the hatch is skewed, the hinges are inspected. It happens that the screws in the hinges become loose, and this causes the door to not close tightly. This problem can be easily resolved - take a screwdriver and tighten the screws until they stop.
What else should I do to eliminate error E40 on SMA Electrolux? We activate the operating mode, press the door with our knee or hand, hold it for several minutes until we hear a characteristic click. At the same time, an icon will light up on the screen indicating that the hatch is locked.
Experienced technicians advise trying to disconnect the machine from the electrical network, wait about ten minutes and try to turn on the unit again.If the reason was hidden in a small module failure (due to a power surge), then such actions will help the machine to reboot.
The hinge overhangs fail due to excessive pressure on them from above. The lock breaks if attempts are made to open the hatch during the washing process. A power surge entails the failure of the microcircuits. We do not exclude the wear of the machine itself - any Electrolux part can be used for no more than five to eight years in an intensive mode. Checking the UBL
This type of breakdown, such as a lock failure on an Electrolux washing machine, is the most common. The reasons may be power surges, irregularities in use, wear of the element. Many Electrolux models use special "thermo" locks. To make sure they are working, it is necessary to check them with a tester, for which the lock is removed from the machine body. We act in this way:
if the E40 error is triggered, the washing machine must be de-energized,
- dismantle the cuff made of rubber material, for which the unit is slightly tilted back; unscrew the screws that secure the lock. You will find them immediately after removing the seal. Now the lock blocking the hatch can be easily removed;
- disconnect all the wires connected to the lock;
- using a tester, the lock is checked for operability. The device is turned on, the probes are applied to the contacts one by one. When checking the phase and neutral contact of the lock, a three-digit number will appear on the device screen - normal. But when the "ringing" of the neutral and common contacts gives "0" or "1", then your lock is out of order. In the case when the contact check does not reveal anything, the cause of the failure may be hidden inside the lock itself.If the reason was hidden in a small module failure (due to a voltage drop), then such actions will help the machine reboot.
- Loop overhangs fail due to excessive pressure on them from above. The lock breaks if steps are taken during the washing process.
. Voltage drop leads to failure of microcircuits. We do not exclude wear and tear of the machine itself - any Electrolux part can be used for no more than five to eight years in intensive mode.
