I just fixed a similar sounding problem on my WFL2000. First check the belt is intact and in place. If so, next find the wiring loom to the motor from underneath. Carefully cut the cable tie holding the wires and plastic protective sheet. Remove and re-seat the wiring multiplug and the earth spade connector on the motor. I didn't use any contact cleaner, just pulled the connector out and pushed it back in. Now the motor works.
