SEL error in the Atlant washing machine

The SEL error occurs in the Atlant washing machine rarely, but accurately: the equipment stops, completely paralyzing the wash. Vending machines without screens give an “SOS” signal by turning off all indicators and malfunctioning the selector. You cannot do nothing - you need to urgently diagnose the malfunction and repair the washing machine. How to do this without outside help?

Let's decipher the code

If the Atlant washing machine system throws an error, then the interface module has failed. It is responsible for recognizing programs and, in the event of a malfunction, stops sending a cycle signal to the control board. The washing machine loses control over the washing process and, for safety reasons, turns off on its own. To bring the machine back to life, you will have to check the control panel for functionality.

The Atlant washing machine shows the “Sel” code due to an interface module error.

If the indicators on the dashboard do not light up, then there is a high probability that the reason is due to a number of unpleasant problems.

1. Wear of buttons due to the long life of the machine. This also includes keys sticking due to detergent or dust getting under them.
2. Faulty gear selector. The rotating mechanism is clogged or damaged.
3. A problem with electronic controller.

In this case, the first thing to do is to follow safety precautions. Sticking keys and blinking indicators on Atlant machines are alarming symptoms that require immediately disconnecting the washing machine from the power supply. Otherwise, the owner of the machine will experience a short circuit and fire. The next step should be consistent diagnostics or calling a professional repairman.

We are trying to fix the problem

To fix the “Sel” error on Atlant washing machines, you need to act consistently. First, we reboot the machine by disconnecting the machine from the electricity for 15-20 minutes. If a system failure was the culprit, then restarting will clear the error. Otherwise, we continue to look for the cause of the malfunction. The problem area is identified by checking a number of machine parts.

• Wiring, contacts and connectors connected to the dashboard from the control board. Carefully remove the top cover and visually assess the condition of the cords. If we detect a burning smell, darkened or damaged insulation, or loose terminals, replace the old one with a new one.
• Control board and selector. It is not possible to visually assess the performance of these elements. A thorough diagnosis is required, for which the parts must first be removed from the housing.

The control board requires careful handling, since the replacement part is very expensive.

To assess the condition of the selector and board and begin repairs, you will have to take them out. We proceed like this:

• disconnect the Atlant machine from electricity;
• pay attention to the powder receptacle, find a latch in the middle of the tray, by pressing which you can disconnect the dispenser from the body and remove it;
• release the bolts located behind the tray;
• remove the front panel.

It is recommended to photograph all the connectors and wires attached to the panel so that during reassembly you do not confuse their location. Next, remove the wiring, disconnect the bolts holding the module and take out the board. Similarly, we free the selector. Next, we replace all spare parts with new ones.

Control board diagnostics

A new selector and board are not cheap, so it is often cheaper to fix faulty systems.To do this, we inspect the board, clean the burnt tracks, ring the contacts and solder if necessary.

It is not difficult for an experienced electrician to solve the situation with the displayed “Sel”, but without practice and knowledge it is better not to experiment with the parts. Ideally, you should contact a service center for advice. It is likely that it is cheaper to buy a new machine.
