I HAVE A GU3200XTP AND LIGHT BLINKS 7 TIMES AND IT WILL NOT START AND CLEAN WHY

SOURCE: 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.

SOURCE: light flashing

reset the dishwasher by touching heated dry and normal let it run through that cycle then through a normal cycle got the error blink again. Reset dishwasher by touching heated dry and normal, ran the test cycle, next ran a normal cycle but turned off the heated dry. This allowed the dishwasher to run through a complete cycle did not get the error blink and confirmed that the heating element was out.

SOURCE: not working

Solution #3 is good, but you need to hit "High Temp Wash" and then "Heated Dry" back and forth 3x to reset the computer.

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 cleared. 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 causes below. Heater circuit problem: ■ Open in heater. ■ Open connection or component in heater circuit. ■ Faulty heater drive circuit on control. 1. Check operation of heater in Diagnostics cycle. 2. Unplug dishwasher or disconnect power. 3. Check resistance of heater and all components and connections in the water heating circuit or heat dry circuit.

Hi

Thanks for using FixYa. If the clean light flashes 7 times, pauses, then repeats...

When the dishwasher doesn't sense a water temperature increase, it stops working and locks the functions (clean light flashes 7 times, all buttons are non responsive). It does this as a safety in case the element is broken and feeding electrical current into the water.

To resolve this you will have to reset the console. Do this by closing the door and press these buttons in sequence...

-high temp wash
-heated dry
-high temp wash
-heated dry

...all the lights will turn on briefly and the machine will start a diagnostic cycle. You can press cancel or let the diagnostic cyle finish (1-2 minutes).
You should now be able to run the dishwasher as normal.

If the issue returns, you could have a problem with the heating circuit (ie. element, thermostat or wiring).
It rarely happens but it could also be the door switch not engaging properly when the door is closed (slightly bend the door latch down making sure it doesn't hit the door when you close it).

Please do rate the solution and revert for further assistance.


Thanks
