wma44 hotpoint. Could see electrical arcs under the machine. Didn't know what was causing it as it only happened when the drum turned. It did eventually get worse and went bang and the control board was destroyed. Changed control board and brushes and when I put it on, again when the drum turned it just went bang and another control board was destroyed. Have now changed motor and have put in another control board but I'm still seeing the electrical activity going on when I look under the machine but only when the drum turns anticlockwise. Any ideas? I'm cracking up!!
