proline PDW041 cuts power on empty cycle?

how can i fix my proline pdw041 dishwasher machine. every time i put it on, on the empty cycle it cuts the electric off at the mains and it can take me up to 10 goes to get the electric back on to move the switch. it also leaks at the front right underneath the machine and i don't know why.
if someone out there can give me some answers that would be great
