Beko WMB91242LB

Good morning all, I have a problem with my Beko washing machine. I was watching T.V last night when the RCD for the kitchen tripped, the washing machine had finished it cycle and I loaded into the dryer. This morning I have checked the fuse's and they are ok. The control panel is dead and I am unable to find any schematics for the machine. I did some googling and it returned that this part (p/n 2817690101) is responsible for the DC voltage (Panel and such I suspect.) Can anybody please confirm this. I get 30v on the left 2 pins of KN12 and nothing on the right 2 pins of KN12.

 

Any advice would be great before I go buying components I may not need.

Regards

Jay

Hello there Jay. I would strongly recommend against guessing at parts. I constantly hear from people who have wasted lots of money buying various parts. No part should ever be replaced unless you know it is faulty. If you happen to be an appliance engineer with a van load of parts then it's not such a problem to speculatively swap one out to see if it fixes the fault. But if you have to order and pay for one, and then will be unable to send it back then it is a big gamble. If the washing machine tripped the electrics then the first thing an engineer would need to do is to test the washing machine with an insulation test meter. This would put 500 V DC through all of the parts and wiring in the machine to detect if there is any leakage to earth. Without such a meter, and it's a specialist meter, then you are unable to assess what has caused the washing machine to trip the electrics (Washing Machine Tripping or Fusing Electrics).

It's always possible for the electrics to trip and then once reset everything appears to be all right. But if yours has been reset and now something is not working properly this implies that some part has failed or been damaged. It is possible that the PCB you show has failed. But it is also possible that another part on the washing machine such as the motor, or the heating element, or even a wire rubbing on the casing somewhere has caused electrical damage to it. In such a case a new PCB could also get damaged.
