Dishwasher seems to run normally but timer clicks down to 1 minute and continues to run. I can cancel and drain. Rinse and hold runs fine, fills, runs and drains. But short-wash does not drain nor stop -- runs down to 1 minute and continues to run ---- and run times have increased from avg 29 mintues to 39 - 43 minutes. Incoming water temp is 128 degrees. Red heater wire from control module puts out 120 volts after a few minutes and continues throughout the cycle. Amp meter on the red wire reads initially 4+ amps but drops to below 2 amps in a few minutes throughout cycle. Bypassing the heater wire (made up a 'y' fitting to provide power to black/grey wire connector to module and continuous 120 volts to red wire) --- amp reading to heater red wire is still just below 2 amps. Ending water temp in washer is about 106 degrees. Do I have a bad control module, heater or ?
ANSWER John, You most likely have an issue with the water heater and or sensor, based on your post. If the water temp. is low, or doesn't increase during the wash cycle, the control will act irratic, and at the end of the cycle will have water and "stall" with 1 minute in the display, while the ontrol attempts to check and re calibrate itself. The easiest way to check for this is to start a cycle and wait 3 to 5 minutes, and check the water temp. the temperature should increase by two(2) degrees per minute, so you'll need to do several checks or use a multimeter with a temperature probe. If the temperature doesn't increase properly, replace the heater assembly 00480317.
