Hello David,
I have the same problem with my washing machine.
I followed all the instructions suggessted and tested the D7 and getting readings one way only.
I tested all others and getting readings as well but the D6 giving readings both ways but the other way only for a short period.
any help will be much appreciated.

thats a different board and the D6 reading is probably a capacitor charging

have you got a reading across R1 ?

Dave

Hi David,
thank you for the quick reply.
The R1 reading both ways as in the pictures.

well if it was me i would change U1 and see what happens

please be aware when this board is live there is 300v DC on one of the capacitors

Hi Dave,
thank you very much for your suggestion.
This is what’s written on the IC:
LNK564PN
8t035n
I tried to Google it and found the one in this link:

https://www.digikey.co.uk/product-detail/en/power-integrations/LNK564PN/596-1039-5-ND/865315
do you think it’s the same?
​​​​​​​many thanks

I was wondering if anyone can help me with my issue. My elderly mother has the same washer dryer. Just under 2 years old. 5 months or so ago the machine kept cycling through the spin settings in the display as if the button for spin speed was stuck. I messed around with and seemed to get it working without doing much. It was fine for a while but now it is having problems with powering up. It will work sometimes and other times you need to press the power button several times to get it to go on.

Is this fault likely to be D7 related or potentially the front PCB where the power and spin function buttons are located? Any advice would be welcome.

[electrofix]

if D7 fails machime would be completly dead

Clean the front panel to make sure its not contamination causing the problem

Thanks Dave I was thinking something like that. Its just when I read on here about D7 issues I wondered if you could get intermittent D7 problems.
