single phase induction motor judder!

    I have a dishwasher that has a fault!

    The pump that recirculates the water has started to run slowly and has a severe vibration, it appears to be a simple induction motor, the type with a single "C" laminated core and a pair of coils on the legs of the "C".

    The rotor sits between the ends of the "C".

    The rotor is magnetised! which is something I didn't expect as I believe it's a squirrel cage type motor.

    Should the core be magnetised like this, the magnetism appears to be preventing the roter from turning, the magnet locks the roter every 180Deg of rotation.

    Any suggestions?
