Call an electrician and have your electrical in your house checked out or disconnect the power in the unit and run an extension cord from another room and circuit from your panel in the house and hook it up to the black and white and green wires inside the junction box under the unit. If you run it off the power from another part of the house and it completes the cycle and works good then you know it's an electrical problem in your dishwasher circuit in your walls or breaker......and if it has the same problem plugged into somewhere else then you know it's the machine...........and do not hook up your dishwasher to a GFCI circuit alot of idiots do that and the motor trips the GFCI from amp draw. Also try and make sure your dishwasher is on its own circuit if you can if you have an old house with very little breakers and a non dedicated circuit your running something else that's causing the circuit to blow or have interference with the machine. Good luck
