My zanussi jetsystem, goes through its cycle, water goes in and drains again, but the drum doesn't turn. The belt is on the drum, the threading is good however when the cycle time is due to spin it doesn't. HELP!
If the drum does not move at any point throughout the wash/spin cycle you could find yourself in need of motor brushes, that is, if the model you have (with which I am not familiar) utilizes a motor which uses brushes. If it's a brushless type you'd be better off calling out an engineer.
Unplug if you are gong to investigate further yourself.
