Re: whirlpool gu2400 clean light is blinking 7 times
Yes this is a heater fault detection error. The unit may not be heating the water resulting in unsanitary dishes so the unit shuts down in this fault. Also the door may not have completely shut resulting in the heater not working, but everything else does (the heater common line is broken at the door switch. Clear the fault by entering diagnostics with this key dance heated dry, normal, heated dry, normal. All the leds will light, you can then press cancel and try another wash cycle. If fault occurs again, you must repair heater problem.

If the clean light blinks four times and then pauses and then blinks four times again and repeats, the problem is your pump motor. If there is water under the DW the pump clamp has probably failed and sprayed water onto and inside the motor. Call a certified Kitchen Aid repair service.
Can be caused by detection of a heater circuit problem. You can reset by running the diagnostic cycle. To turn of the diagnostic cycle, press: HEATED DRY button, then NORMAL button, HEATED DRY button again, then NORMAL button. The cycle runsfor ~22 mins. When it completes, the blinking light should go out. You can then try running the dishwasher again. If the problem comes back, the heater element or Thermister may need to be replaced
Control is programmed to stop
running and not allow any
further cycles if it detects a
water heating problem (no
temperature increase detected
in heated Main Wash on
3 consecutive cycles). Control
blinks the Clean LED 7 times
repeatedly and disables the
Start/Resume key until
Running Diagnostics clears the
control and allows it to operate
again. The water heating problem
must be fixed or the control will
stop running again. See potential
Heater circuit problem:
■ Open in heater.
■ Open connection or
component in heater circuit.
■ Faulty heater drive circuit on
1. Check operation of heater in
2. Unplug dishwasher or disconnect
3. Check resistance of heater and all
components and connections in the
water heating circuit or heat dry
The same thing happened to our Mr. Coffee this week! I followed the instructions about running vinegar through, then rinsing several times with water. However, the light would not stop blinking. We did by-pass the light by setting the timer for delayed brewing and it worked. However, that blinking light came on again. Then, my husband tired the vinegar wash again but instead of doing it one time, he ran the same vinegar through 6 times until the light went out! Then he proceeded with the water rinse. Our Mr. Coffee is working again!
is the cean light blinking 7 times and then repaeating?? If so this is a water heating fault and means that the computer sensed that the water temp didnt rise just 3deg in the last main wash cycle. If its not blinking 7times then repeat, it sounds like the user interface (membrane switches) have failed. Let me know more and i can help.
