I have a problem with my Beko wma1512w in so much that the drum won't turn during the wash cycle. The machine fills, the programmer moves on, the heater can be heard heating the water, the pump is pumping, but the drum is not moving, or even attempting to move. I've moved the motor by hand and it is free, as is the drum. Any ideas before I start taking it to bits - could it be the control circuitry for the motor or something? Thanks in advance.
