Well, I had a real shocker. Our 4 year old washing machine, made in NZ (or is it Australia?), bit the dust with a nasty burnt electronics smell. service guy comes, figures out its the motor controller. cost? 380 $US!!! hooo-leee-sh*t. I coughed up the cash as it was cheaper than buying a new one but I'm royally p----d. machine seems good as new with the replacement.
So, I kept the dead one and opened it up expecting to find something burned but nope. it looks clean. I know the fault is within because the new one made the washer work. my goal is to figure out the problem and fix it for a spare. It turns out it's more than just a motor controller - its the power supply, motor controller (lots of FETs), sensor interface and there appears to be a 40 pin microcontroller (house marked, of course). Oddly enough, its a single sided board with a mix of TH and SMDs.
anyway, before I go and figure out the schematic (at least parts of it), I was wondering if anyone has experience with this unit? Or maybe some one can point me in the right direction. Maybe some of you aussies or kiwis? It's from a Fisher-Paykel clothes washer GWL-11, I believe.
