Re: wma31
Helped a friend out recently he had fitted a new drum on a wma31 and then found the same problem.
Fitted a new module to find the same. washing, but on a spin it turned once and continued to distribute.
Problem, he had reversed the two wires on the relay r.hand side (on the board) One insulated the other non insulated terminal.
One side pressure switch the other heater. many years ago I did the same after fitting a new drum. A quick check in the manual put me right. 😳
