How to disable UBL washing machine

Sometimes it is not possible to immediately replace the UBL: the store does not have the right part or it is too expensive. The Internet does not help either - the order is usually delivered in 7-14 days. You have to either live this time without a washing machine, or try to bypass the electronic lock. A temporary solution will be to start the machine with the blocker turned off. Let's figure out how to turn off the UBL of the washing machine and "cheat" the system.

Getting access to the castle

Turning off the UBL means closing its contacts - then you can start the washer without a blocker. But first, the device must be dismantled. The easiest way to do this is through the top cover. We act like this:

• Disconnect the washing machine from the mains,
• Open the hatch door,

• We look at the keyhole - the hole in which the door hook is fixed,
• We find two screws next to the well and unscrew them,

• Unscrew the screws holding the top cover from the back panel,
• We push the cover away from us and, having lifted and squeezed the latches, we disconnect it from the case,

• We tilt the washer back so that the edge of the drum “unsticks” from the front wall,
• We put our hand into the formed gap to the blocker,

• We unhook the wires from the ubl and, pulling it towards ourselves, we take it out.

There is another option for dismantling the UBL - through the hatch door. It is necessary to open the drum, remove the cuff with the clamps fixing it, and then get to the device through the gap between the body and the tank. It's easier and faster, but more risky. The point is the sealing gum: it is very difficult to pull it back correctly. The slightest mistake will lead to a leak.

We create a chain without UBL

Dismantling the UBL is the first step. After that, you should make sure that the “brains” of the washing machine think that the lock is working and activated. To fool the control module, it is necessary to close certain contacts on the socket of the device . Then the board will record that the lock is on and give permission to start washing.

To understand where to close, you should understand the UBL contacts:

• When starting the cycle, the washing machine supplies voltage to the contacts N and L,
• Under voltage, the thermal coil heats up, and with it the bimetallic plate,
• The plate bends, closing relays L and C,
• The board reads the signal and starts washing.

The closure of relays L and C is a signal for the control board about the triggered electronic blocking. Accordingly, in order to turn off the UBL, it is necessary to first “connect” the mentioned contacts. For these purposes, any proportional jumper will do.

After forced closing, a new cycle does not start immediately. A few minutes after turning on the start button, the board “thinks”, but in the end gives the go-ahead for washing.

Some modern machines cannot be deceived by manual closing. A special protective algorithm is programmed in their system, for which only a short circuit is not enough. When trying to manually “tune”, the sensor will detect a malfunction and display an error code. But most washers do not notice the "extra" jumper and start up.
