My Fridgidaire dishwasher washes, dries, and then goes to "clean". All is fine until it reaches clean as it does not turn off. "Clean" is lit and the light does not go out unless I reset the circuit breaker. If I don't reset I can not use the dishwasher. Dishwasher is not that old and was manufactured in 4/08. Model is FOB105OREB2. Any thoughts as to the problem and how to fix it?
