Beko PCB keeps burning out - Advice needed

[Alex Davies]

Hi, I have a Beko WI1573 washing machine and I have had three instances where the circuit board which contains the LED fails. The screen suddenly doesnt display anything during a cycle.

I have replaced this board andthe machine works as normal again. The first time i did this it lasted months, the second time it only lasted a 2.5wks.

I have attached images of the last 2x circuit boards. 

Has anyone had this before? Does it suggestthere is a problem elsewhere that is frying the boards or that I am just being sent faulty spare parts (each time they were bought from espares so they are new).

Thanks

Hi there’s another topic on here about Beko PCBs where display goes dead. Have a look in case it’s the same issue.

This is it

Thanks for the reply.

Unfortunately not, I checked this post previously and my issue doesnt seem the same. The PCB appears burnt out and I cannot find the same diode on my PCB board.

It's definitely burnt out is it? PCBs and modules often get black sootlike deposits on them that wipes away, and many people mistake it for burning. I can't be sure from the photos.

If it keeps burning out something is badly wrong, or they are complete rubbish. It's hard to suggest what to do though apart from checking all connections. If it's blown, and there's damage to the components and printed circuit, then another part or a low insulation issue could cause it. Though it could be something internal in the pcbs at fault. You'd need to understand which part of the circuit has blown and what that section controls, i.e is it the section that gives power to the motor, or the heater, pump etc. But information on pcbs is not available.
