keep getting a F01 fault and the circulation fan runs continuosly. I contacted kitchen aid and they had indicated that the sensor was probably the problem and there s only one sensor so I ordered it and replaced it , but stil keep getting the reoccurrung fault after a day ot two of operation. any idea's . all i would need is a troble shooting manual but kitchen aid say's there is noy one and i need to call for service. Ya right It can't br that difficult.
