Whirlpool WDT730PAHZ0 Tripping breaker

[mrmfwilson]

When I try and run the dishwasher it trips the breaker.  To try a brief test, I set the wash cycle to one hour wash.  This doesn't use the sani-sense or the heated dry.  The washer turns on and seems to try and start a couple of times then starts and blows the breaker.  From what I have read about different models it sounds like the inline heater or the pump may be bad.  How do you test the heater and pump?
