My 13 month old dishwasher beeps repeatedly after about 20 mins of any program. Upon opening the door the start button flashes three times continuously. There is no evidence of any heating at all. I also believe that the house breaker unit tripped when the dishwasher was on. (maybe coincidence), but as a man of logic believe it is a heater problem.
I would appreciate where to look and how to rectify it.
