Penguin45.

That might explain something, it’s been a while since I was working on the machine. I replaced the seal and bearings. Maybe I messed something up when I reassembled it. It didn’t sound right when it started to wash.

Since then I have aquired a couple more dud washing machines so I may be able to salvage one.

IRF840 is a N Mosfet 500V 8A 125W.
My little book of tricks tells me a MTP 8N50, 2SK555, 2SK894, 2SK1496.
Any of the above MAY work.. But you will HAVE to look up their datasheets and verify this against the IRF840’s data.

Cheers.. 😯

OH>>> Don’t forget to check the diodes that are between the S-G pins… These protect the transistors and probably will have taken a bashing too!..

Thanks for that. My question was asking for the transistors which drive the IRF840’s

Thanks
