We have had this problem with the circuit going out for a long time. The dishwasher is kitchenaid KUD1230B. The breaker is rated for 20 amp the unit says it draws max 12.5. When you get to the rinse and hold cycle it throws the breaker. Not sure if it is the unit or electric supply. And way to confirm before proceeding? You hit the circuit breaker after it throws it and you reset there is usually not any other problem. Could it be when it goes to rinse and hold I'm coming to the problem? What would be probable causes. I'm thinking when it goes to next cycle something is not right? Don't have a clue other than info given.

My guess is there is a transfer at this point but I don't know how to pin point problem area.
