As long as the house wiring is of the proper size to handle the power required to run the dishwasher (which usually draws 12 to 14 amps) then I would be suspicious of the circuit breaker. Each time a breaker is tripped it becomes just a bit more sensitive to the power draw going through, which means that it will trip a bit sooner each time. Try a new breaker and see if it remedies the problem.
