We covered how to tell if the voltage, is real or not.  Using a wiggy with LOW impedance will not show the 116 volts at drain pump 2 an1.

Has any one else seen this, and did a new control board fix the problem.

I isolated, disconnected all external outputs, water solenoids, lid switch, shifter and motor.

I think the ghost voltage is being induced to the neutral wire , because K-7 relay was open.

Do we have anybody here that is a board fixer, that might be able to give a answer.

Not sure if customer even went and got a new board.

I just want to know for sure, and get closure on the how and why it happens.

I had this on my father in laws cabrio,  different washer, but pretty similar problem,  it would send power to the pump, however the neutral return through the board had somehow failed.  if you tested for continuity through the board to the plug you'd get nothing for the drain pump. on the cabrio though their is a circulation pump that plugs in next to the drain pump, I checked that and found that oddly enough the neutral from that pump was fine, tied the two neutrals together so that the drain pump used other neutral and it works.   still going strong after 2 years.   

probably worth noting that again, this was my father in laws washer in an unfinished concrete basement...  and I explained it was either try this or a new board...   on a normal customers washer I would likely quote for a new board rather than take on the liability of rewiring experiments...
