Re: Hotpoint WM51
First things first, most faults on these boards are caused by other component failure, door locks and motor faults two likely candidates. Have these been checked/replaced/repaired?
When you say he has blue, black & green wires, I assume you do not mean wires but connector blocks.
There are only two separate wires on these timers that fit at the very front lower edge of the board, all the other connections are via connector blocks.
If you can trace the wires from each block to its destination I may be able to help.
Please make sure the plug is removed.
