sounds like the motor carbon brushes have worn down.remove and inspect ,should be about 10cm long,it could also be a fault on the motor if its started tripping out the main consumer unit.it almost certainly motor related from the description you have given. when you drained the machine did you get any electrical devices wet?if you have then you have created another issue and will have to wait for the components to dry out .
