Tip & How-To about Maytag MDB8959AW Builtin Dishwasher
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.
