Hotpoint aquarius1100 electrical prob.

my machine has just been moved from one house to another 4th floor flat today,and upon using it it seemed to work fine then it tripped the switch on that circuit ,it then seemed to work fine to just spin if i put it on that part of the cycle.now about half hour later it trips off immediately that i turn the power on,first time it happened it actually had time and i could hear it start filling then it tripped after 2 minutes or so. Each time i tried after it got shorter and shorter till noe it just shorts out.
