Hi everybody,
While the washing machine was running, about 10 minutes before the end of the program, the washing machine stopped suddenly. There was nothing on the screen. After disconnecting the power and restarting it, the screen did not light up. There was only a relay sound. I did not notice anything blowing on the board. I disconnected everything from the board except the power line. The main thing is the same, the screen does not light up and only the relay sounds
Any idea,,,
Thanks in advance

 

You begin by telling us the brand name and model of the machine.

Hi,
Does your machine have an Offline regulator?
Something like; Power Integrations | LNK304PN - Datasheet PDF & Tech Specs (datasheets.com)
Good luck......

Yes, but it's number is 5A464d /SK732

Hi,
Looking at the 10 ohm resistor, (bottom left) I would think your regulator is OK.
Have you looked for any soldered in fuses.
Good luck............

10 ohm resistor is OK, and I didn't find any blown FUSES.
What you think about the root cause of no power and just the relay sound.
Thanks for your help,,,,

 

This is the circuit diagram from the datasheet, see if you can check anything that is similar.
