Chosen Solution
What caused the problem: chlorine bleach solution dripped into the motor control board. When the machine was turned on, it sparked and audibly fused and ceased to function. What I have done: I extracted the control board from the washing machine. See photo of the board.
The only visible damage is the two fused SMD resistors seen in the photograph next to the two capacitors. The visible value of the two blown SMD resistors was destroyed in the short. What I want to find out: I want to know their resistance-value so I can replace them. There appears to be no other damage to the printed circuit board. Any advice about this problem will be gratefully received, especially knowledge of the resistance-value. I can then replace the resistors and reinsert the board and test for other possible damage. The Fisher and Paykel upright washing machine Model is WA75T65GW1 The Motor Control Panel board says: SD P7CP Ver 48 11:40:49 11/03/10 421389NAP (062525)
Hi @annakilligrew , Just thought you’d like to know that searching online using the board number only, (421389NAP) gives plenty of results for the board and I was hoping that there would be one shown without the protective plastic cage so that the board itself and possibly the resistors could be seen. Unfortunately this is not the case. You may have better luck using this method. Sometimes you may be lucky at metal recyclers that they have your model washer and will let you look at or even take the part. It never hurts to ask ;-) You may even be luckier still and find one on the kerb at the next kerbside hardware pickup in your area. If you have this of course. The board is considered disposable by F&P and that seems to be the reason why there are no schematics available (none that I could find out about anyway). If you decide to replace the board with a replacement (plenty available online) be aware of the Note contained in this link Good Luck!
