Error E91 in an Electrolux washing machine

Error E91 in an Electrolux washing machine Many experts note that Electrolux equipment has one of the best troubleshooting systems. You will be able to understand this yourself if error E91 appears on your Electrolux washing machine one day. The fact is that this error informs the user about the loss of communication between the main control board and the display board. At the same time, in household appliances of other brands, housewives receive only vague information about the problem that has occurred, and not an exact indication of the damaged unit. Thus, the Electrolux user does not need time to find the problem, but only to restore it, which we will now do.

Do you need diagnostics?

If you find fault code E91, then first of all you need to determine what exactly caused the error. It may appear due to damage to the cable or one of the conductors, or it may occur after a complete failure of the control module or display board.

It is difficult to accurately localize the fault with your own hands without a multimeter, so it is much easier to call a service center specialist. In this situation, it is not necessary to pay for repairs, because if the board cannot be repaired, then you can replace it yourself, and only pay the technician for diagnostics. Let's check the Electrolux module

This will significantly save the family budget, because if it is almost impossible to repair the control module without extensive experience and knowledge, then anyone who has detailed instructions at hand can cope with the replacement. Therefore, if the expert indicated the need to replace the element, or you are confident that you yourself can determine the extent of damage to the board, then proceed to the next paragraph of the article.

Remove the old board and install a new one

Electrolux “home assistants” are distinguished by the fact that their control board is installed immediately behind the front panel. The exact location depends on the type of loading, but you won’t be able to miss the module given the large size of the part. What should I do to remove the part with my own hands?

Disconnect household appliances from all communications.
Remove the top cover of the CM by unscrewing the fixing bolts, then sliding the panel back and pulling it up.
Remove the powder receptacle.
Unscrew the screws holding the dispenser.
Remove the bolts securing the control panel.
Carefully disconnect the wires from the panel and then remove it.

It is better to record each stage of work with a camera or smartphone, so that when reassembling you have an example of the correct connection of wiring and other elements at hand.

Unscrew the screws that secure the control module in the machine body and remove it.

Now you need to carefully examine the control board for problems. Pay special attention to the presence of burning, rust, and mechanical damage. In rare cases, at home, you can restore the operation of the control module after replacing the capacitor or soldering the tracks, but most often you will need to call a technician to repair the board. In any case, do not attempt to repair the module yourself if the manufacturer's warranty is not yet complete, otherwise it will void it.

When you have a new or restored control module in your hands, you need to install it in the seat according to the instructions in the reverse order. First of all, you need to fix the board in the case, connect the wiring to it, and then install all the other components.

Be sure to run a test work cycle to verify the repairs made. Do not move far from household appliances during operation in order to promptly respond to possible emergency situations. If the wash is completed without incident, the replacement is successful.
