How to turn on a washing machine without UBL

Until the brain of the machine receives a signal that the hatch is closed, the cycle will not start. Water will not begin to fill the tank if the system is leaking. However, some craftsmen still manage to deceive the control module and turn on the wash even with a broken UBL, the main thing is that the blocker contacts are intact. Let's figure out how to start a washing machine without UBL. To be more precise, with it, only with a faulty one. We'll tell you how to proceed.

How to remove the machine lock?

Of course, the surest way is to immediately replace the UBL when a breakdown is detected. If you can’t buy a new lock yet, you can go another way - slightly fake a non-working lock.

There are different ways to remove the blocker. Some craftsmen remove the hatch cuff and then dismantle the lock. The risk of this method is that the average person, due to inexperience, will then find it difficult to return the sealing gum to its place. Therefore, an easier option is to get the UBL through the top of the automatic machine. The algorithm of actions will be as follows:

  • Turn off the power to the washing machine,
  • Open the hatch door wide,

  • Find the hole where the tongue of the lock goes,
  • Unscrew the two bolts located next to the hole for the hook,

  • Remove the top panel of the case by unscrewing the two screws holding it,
  • Use your hand to reach the UBL through the top of the machine and carefully remove the chip with wires,

  • Slowly pull the lock out of the housing.

Next you will have to work with the contacts of the broken lock. Let's figure out what to do with the dismantled blocker and how to turn on the washing machine.

Simulating enabled UBL

To start the machine with a broken lock, you will have to convince the control module that the lock is in absolute working order. You can deceive the intelligence of an automatic machine if you close the UBL contacts in the locking position. To do this, you need to understand how the mechanism works.

The standard blocker has 3 contacts - N, L, C. The first two are supplied with voltage. Due to this, the thermal coil heats up, which heats up the bimetallic plate. The hot plate then closes pins L and C together.

Closing the two outer contacts is a signal to the smart module that the hatch door is tightly closed. After this, the “brain” activates the inlet valve and water begins to flow into the tank.

Having returned the converted blocker to its place, try starting the cycle. The machine may “think” for a few minutes, but in most cases the wash will start. There is no need to yank the door to see if it is securely closed. The locking device does not work, so opening the hatch will be very simple.

This trick will not work with the most modern machines. They have a protective algorithm, so closing the contacts with a jumper will only result in an error code being displayed on the display. Such technology is rare today, so you can try to “deceive” the electronic module.
