you said you check the pressure switch and blown out the airdome hose. Good. You also need to rule out the possibility of a hole in the airdome hose.
next remove one of the rear drum baffles and look down into the sump boot area(careful sharp edge)...I found alot of slime and gookus down in there. This also happens to be where the airdome hose connects and a glob of slime was periodically finding its way into the end of my airdome hose, fooling the unit into overfilling...drove me nuts. Clean as much of that crap out as you can and blow it out from the top again.
it is worth mentioning that you need to make sure the water valve is not sticking open. When it is overfilling, unplugging it should make the water stop...if not bad valve.

... I am back on the Neptune at the moment. I have gone through and ohmed out all the water valves, switches, etc and second time just to make sure I didn't miss something. No luck yet. But, did take some pictures of the old control board and the damage to the P7 connectors traces (Excuse my quick repair).
The 3 traces that burned go to wires 7, 9, 15 Hot Water Valve, Cold Water Valve, Timer.
As I said I don't know that I may have caused this as at one point I held down the start button
and rotated the timer trying to get the washer to work
(Doesn't sound like as much of a good idea now as it did then).
But, ohm out the valves. I want to say they were 1020-1030 or so according to my fluke meter.
I looked carefully at the wiring and connector for signs of damaged but don't see anything.
I am a bit lost, I am about to pack the thing up and take it in but I hate being beaten by it.
I can usually fix most things and it kills me not to be able to figure this out. Any help is very much appreciated.
