Error i50 on Electrolux dishwasher

Error i50 on Electrolux dishwasher Modern household appliances can sometimes be understood even without experience and knowledge, because the equipment always clearly reports its current state. For example, a very common error i50 appears in a situation where the triac on the control module responsible for the circulation pump breaks down. If the model does not have a display, then the equipment reports this problem with an indication that repeats five times. Moreover, in addition to the triac, the problem can also be caused by a failure of the circulation pump itself. We will carry out a full diagnosis and restoration of the machine at home.

We will inspect and repair the control board

Error i50 in an Electrolux dishwasher is almost guaranteed to inform the user that damage to the PMM control board has been detected. However, this is not yet a reason to start disassembling the device and inspecting the electronic module, because a banal system failure could have occurred with the device. What should I do to check this?

Turn off Home Assistant using the power button.
Wait about three minutes, and then unplug the equipment.
When the equipment is de-energized, do not touch it for at least half an hour, and then reconnect it to the power supply.
Wait about ten minutes more and then start the Electrolux dishwasher.

The described manipulations should be repeated several times - if in this case the error code does not disappear, then you will have to move on to further tests.

A one-time failure is a common cause of the i50 error, but if a reboot does not help, you will have to partially disassemble the equipment. This should only be done in a situation where the warranty period has passed, otherwise disassembly will void the warranty.How to get to the control board that is installed in the door of an Electrolux dishwasher?

Disconnect the equipment from all communications.
Remove the narrow bezel mounted under the door, which is secured with latches.
If your appliances are built into the kitchen unit, then carefully remove the decorative facade from the door.
Open the wash chamber door and remove the screws on both sides securing the inside and front of the door.
Open the door to reveal the elements hidden inside.
Locate the dishwasher control board where the wiring is connected.
Carefully examine the part for damage - burnt triacs, broken wires and much more.

If a part needs to be removed for repair, be sure to take several photographs of the correct connection of the wires - an example will be needed during reassembly of the PMM.

If the triac is really burnt out, it will be visible to the naked eye. In this case, you can fix the problem, but you will have to carefully remove the burnt element, buy an analogue and place it in the place of the damaged one. For such repairs you need a pin with a thin tip and a wealth of experience in such work. The triac of the circulation pump burned out

If you are not confident in your abilities, or if the problem could not be visually detected, then it is better to call a repairman to restore the “brain” of the Electrolux dishwasher. This will help you avoid getting into an unpleasant situation in which you accidentally damage the board even more, making repairs even more expensive.

Let's check and change the circulation pump

Another reason for the i50 error to appear is the circulation pump, which could have failed. What should I do to check it?

Disconnect household appliances from the water supply and electrical network.
Remove all hoses from it.
Remove it from the kitchen unit or move it away from the wall to make it easier to interact with the machine.
Open the washing chamber door, from where you need to remove all the dish baskets and the garbage filter.
Unscrew the screws along the edges of the filter, remove the grille, and then the gasket installed under it, also secured with screws.
Close the hopper door and unscrew the fasteners holding the side walls in place to remove them.
Turn your Electrolux dishwasher upside down and then remove any soundproofing material from the sides.
A device for smooth opening of the door, consisting of a cable, springs and plastic blocks, is attached to the side walls. Carefully secure the springs while holding the door so that it does not fall off and become damaged.
Using a screwdriver, unlock the tray fasteners installed at the corners of the body.
At the very base of the tray, which contains the hoses, there are other fasteners that also need to be unlocked.
In the same place there are plugs and wires that must be carefully removed.
When all the fasteners have been removed, carefully lift the pan and secure the inlet pipe, which will require force, as it can be difficult to disconnect.

The most difficult task is over, because the device is disassembled, the tray is removed, and you have free access to the key components of the Electrolux dishwasher. Take a closer look at the center of the case - this is where the circulation pump is installed - the largest element, to which large bundles of wires go. circulation pump repair

At this stage you need to check the pump coil, which can be done with a regular multimeter. Connect the probes of the tester, previously set to ohmmeter mode, to the contacts of the part to evaluate the resistance. Normally it should be about 50 ohms. If you don’t have an ohmmeter at home, or you can’t disassemble the “home assistant,” you’ll have to call a service center specialist.

If the problem is in the circulation pump, then resetting the i50 error is very simple - you need to purchase a new part and install it in place of the failed one. The procedure is as follows:

disconnect all the chips with wires from the pump, fixing the correct location of all bundles;
remove the small metal clamp installed directly at the base of the pump, which can be conveniently done using a flat screwdriver, which can be used to pick it up and separate it into pieces;
under the clamp the pump is connected to a rubber pipe that needs to be disconnected;
remove the pump from the distribution block located nearby;
All that remains is to remove the pump from the suspension and install a new element in its place.

Installation of the unit is carried out according to the described instructions in reverse order. Try to buy original spare parts that will last longer than their Chinese counterparts. Once you are done, be sure to run a test cycle without any utensils to ensure that the water circulation problem has been resolved.
