How can I tell if the control module is defective?
To see if the control module is bad you would want to check for voltage going into the dishwasher module and for voltage out. If there is voltage to the module but there is no voltage coming out of the module then the module is faulty and would need to be replaced.
My Gaggenau dishwasher starts at 29 (normal cycle) and the counter goes down to 1 and stays there. What could be wrong?
Answer Caroline, The 1 minute in the display usually indicates and issue in the water heating circuit. It is usually due to a failed relay on the control board 00266746 in the door panel. But could also be due to an open heater element or thermostat in the heater assembly.
How many amps is the heater relay? 10 or 12?
Answer Hello D.V.,
I'm sorry, but the manufacturer has not provided this information to us on this part.
When I turn the dishwasher on in any setting, except for rinse and hold, the timer stays on 2H. I'm thinking control module. Could it be something else?
Answer Dan, This may be "normal" "2H –Last wash cycle too long (> 99 minutes). Can be cold inlet water or heating system fault (heater, Hi-Limit, flow switch, NTC, control module heater relay)." Make sure the water temperature in the tub on the first fill is at least 120 dgrs. at the start of the cycle. The control will display 2H whenever, the cycle takes or took more than 99 minutes.
