Tip & How-To about Maytag MDB8959AW Builtin Dishwasher

Flashing or blinking green clean light 7 times?

This dishwasher looks for a temperature rise of the water during a heating cycle if it fails to see this rise for multiple cycles it may shut down and blink the clean light 7 times.

The failure can be wide ranging here are a few things to check before resetting the control.

-The unit not being level so both door switches do not make contact

- The sump plugged up so water is not pumping across the heater (see sump clean out below)

- Not enough water filling the dishwasher

- The heat element is not working

To reset the control use this key dance within 5 seconds press:

HEATED DRY, NORMAL, HEATED DRY, NORMAL

This will cause you to enter the diagnosis cycle once this is finished or you hit cancel the control should be unlocked and ready to use.

CLEAN LIGHT IS FLASHING SEQ OF 7 FLASHES THE LAST TIME TECH CAME OUT AND RESETUNIT, WE TRIED TO RESET AGAIN BUT NO HELP. ANY IDEAS


The cause of the problem is an insufficient rise in water temperature during a pre-set time period. The heater fault-detection program that was added to the electronic control is designed to shut down the dishwasher if the board-test for proper water temperature rise is not sufficient.

You will need to identify possible causes of insufficient temperature rise. These causes may include checking the wiring to/failure of the control, the heating element, the thermistor, the inlet valve, door switch, motor or capacitor. Make sure that water is not siphoning during fill. Once the heater fault detection is triggered and the condition resolved, the electronic control must be reset by initiating a special diagnostic cycle. Use the Product Tech Sheet shipped with each dishwasher — you’ll find it behind the kickplates — to identify the correct cycle sequence. The rapid advance cycle will not properly reset the electronic control.

hi...
The cause of the problem is an insufficient rise in water temperature during a pre-set time period. The heater fault-detection program that was added to the electronic control is designed to shut down the dishwasher if the board-test for proper water temperature rise is not sufficient.
The dishwasher run cycle was modified to add 8 minutes 45 seconds of heat at the beginning of the main wash cycle. If the inlet water at the thermistor is below 110°F, the thermistor looks for a water rise of 4°F. If the inlet water is over 110°F, the test is for an increase of 2°F. If the temperature rise is below specifications, the unit will drain and the clean light will blink seven times.
