Thank you for your question.
I am sorry you are having a problem with the dishwasher. The clean light flashing fault code indicates that the control board did not detect a 2 degree F increase in the water temperature if the initial inlet water temperature was greater than 90 degrees. It will also trip if a 4 degree increase is not detected when initial inlet water temperature is less than 90 degrees.
Possible causes that can keep the water from properly heating include:
Heating element is bad.
Wiring to the heating circuit is loose or broken.
Thermostat (thermistor) is bad. Wiring to the thermistor is bad.
Neutral side of the door switch is bad.
Water not coming in or a lack of water.
Siphoning of water during filling due to improper drain hose installation.
You can reset the control by running the diagnostic test cycle. Start this cycle by pressing the following buttons in this order: HEATED DRY, NORMAL WASH, HEATED DRY, NORMAL WASH. The buttons must be pushed within 5 seconds. After pushing these buttons, all the control lights will turn on and then the dishwasher will complete a short test cycle. After the test cycle, the control will be reset.
You can start a new cycle and crack the door to stop the cycle after the filling is complete and before the spray starts. Open the door and check the water level in the tub. The water should be within a 1/4 inch to just touching the bottom of the heater element.
Check the heater element. If it is not heating, disconnect electrical power and check the wiring. If the heater element is bad, it will need to be replaced. If not, your clean light fault code will return.
If you reset the control and the fault does not repeat, you should be able to continue to use the dishwasher. Monitor the water fill and the heating circuit for problems.
Please let me know if you need further assistance on the repair of the dishwasher.
