Washing machine trips my electricity as its about to spin,

There is almost certain to be a small leak which could be from a variety of things. The water sounds like it has found its way onto your motor windings. Once it starts burning,carbon is left behind on motor.The decision to replace motor and possibly hole in drum is the question.Need to weigh up if a new purchase is possibly the right way to go. Remove covers to see if the source of the leak is visible.
