What should I do if the Atlant washing machine door does not lock? In this case, the washing does not start, and the display shows the error F10.
Error F10 stands for a UBL malfunction: a locking device that locks the door electronically.
In SM Atlant models without a screen, the first and third indicators are lit.
Let’s take a closer look at what the fault code means.
What does the error mean: causes and signs of failure
The Atlant washing machine gives an F10 error, which indicates problems with closing the door. How to independently understand that a breakdown has occurred?
When the electricity supply is cut off, the bollard plates return to shape. The door can be opened.
If the electronic lock breaks down, the door will not open until you de-energize SM Atlant. Even when the machine is turned off with the button on the panel, current is constantly supplied to the UBL.
Another reason when the error code F10 is on the CMA Atlant display is a short circuit. The thermoelement of the lock breaks through, after which it stops heating. It is clear that when the door is open, the washing will not start.
How to fix the situation and remove the F10 error? The locking device needs to be checked.
Types of locks and the reasons for their failure
Atlant automated washing machines are equipped with an electronic lock – the blocker allows you to hermetically close the door. It also serves as protection against inadvertent opening.
A malfunction of the hatch blocking device causes an F10 error on the display: until the hatch is closed, washing will not start.
Types of UBL
To understand how to fix the breakdown, you need to test the blocker. To do this, we will understand the principles of operation of two types of UBL:
- Thermal lock. It is based on two bimetallic plates – when electricity is applied, the plates expand and put pressure on the lever. The hatch door is securely fixed. The reason for the breakdown of thermal locks is the wear of the plates. The photo shows the principle of operation:
- The electromagnetic lock is used by the manufacturer less and less. The device works only when there is electricity. If the electricity goes out during washing, the hatch will not open until the current begins to flow to the lock.
Checking and replacing the lock
Breakage can occur both with the door open and with the door closed. If the hatch is locked in the closed position, you will not be able to reach the UBL.
Let’s figure out how to open the hatch and solve the problem. What do we have to do:
- Unplug the plug from the outlet, de-energizing the Atlant washer.
- With the CM tilted 45 degrees, run your hand through the bottom of the machine to the door (you may need outside help).
- Try to release the latch and open the hatch.
The same can be done through the top of the machine. To do this, unscrew the screws that fix the top panel and remove it. Run your hand between the drum and the body. Unlock the door.
Now about how to remove UBL:
- Open the hatch, unscrew the three screws holding the blocker.
- Bending the cuff, you will notice a metal collar. Using a screwdriver, remove it from the washing machine.
- Bending the cuff, pull out the UBL.
- Remove the cover from the device by opening the latches.
- Unclench and remove the harnesses.
In front of you is a hatch blocking device.
To check, use a multimeter in resistance mode. Connect probes to neutral and phase contacts. If the display shows a number of 3 digits, then the lock is working. Then move the probes to neutral and common. In the event of a fault, 0 or 1 will appear.
If you have found out the cause of the F10 error in the Atlant washing machine, install a new lock in the reverse order. Now start washing and look at the result.
In order for the UBL and the mechanical lock on SM Atlant to last as long as possible, follow the simple rules:
- Do not let children randomly press the buttons on the panel.
- Do not try to force open the hatch after washing until the UBL is unlocked.
