Dishwaher I have a whirlpool dishwasher and after i used it the last time the light on the panel flashes on air dry (control lock) When i try to clear it 2 or 3 of thelights flash at once.

It sounds like you just need to reset the controller. This is done by running (or partially running) a diagnostic cycle, which will clear the error. Here's how to do it: Depending on the model, and the keys you have, press the following sequence of keys quickly (with less that 1 second between key presses:
Heated Dry - Normal - Heated Dry - Normal; or
High Temp - Air Dry - High Temp - Air Dry; or
Hi Temp Scrub, Energy Saver Dry, Hi Temp Scrub, Energy Saver Dry; or
High Temp Wash, Heated Dry, High Temp Wash, Heated Dry.
You will know that you have entered the diagnostic cycle when all the lights light up. Let it run for a few minutes, and then press Cancel to stop the diagnostic cycle and clear the error.

Note: On some of the newer Whirlpool, Kenmore, KitchenAid dishwashers, you start the diagnostic cycle by rapidly pressing the 3 left-most keys in the following sequence: 1 2 3, 1 2 3, 1 2 3.

Not sure which particular model you have got. If turning off the mains power off and on is not helping then you will need to reset the controller. "press your "Normal" button then your "Heated Dry" button alternatively several times (quickly). This should reset the control panel and allow you to resume normal functioning."

Heating Element

If lights are flashing on the control panel, the heating element might have burned out. The heating element heats the water up to operating temperature. After a set amount of time if the temperature isn't reached a light on the control panel might start flashing. The heating element can be checked for continuity with an Ohm meter.

Check Fault Codes

If the display lights are flashing and there is an error code in the display window, check the wiring diagram and tech sheet in the dishwasher that will provide information on the fault.

Drain Pump

If lights are flashing on the control panel, the drain pump might not be working properly. For two-wire drain pump motors check them for continuity using an Ohm meter. If it's defective You'll need to replace it. Drain pumps are not repairable.

Touchpad and Control Panel

If the lights are flashing on the display the entire touchpad and control panel assembly might be defective. If the display works but the dishwasher functions are all out of synch, or some of the buttons don't respond properly the entire touchpad and control panel might need to be replaced.

Touchpad

If the display lights are flickering for no reason, the touchpad might need to be replaced. Sometimes when the touchpad is defective the display lights are flashing randomly.

Hi


Thanks for using FixYa. If the clean light flashes, pauses, and then repeats. When the dishwasher doesn't sense a water temperature increase, it stops working and locks the functions (clean light flashes, 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



Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

Make sure the control panel is not locked. If you press any pad while your dishwasher is locked, the light flashes 3 times and the selection is ignored. If the lock symbol is lit, press and hold HEATED DRY for 4 seconds. The light turns off.

If the control panel is not locked and the problem still occurs press the Cancel/Drain button to drain all water and clear all indicators. (It might take 2 minutes to complete this action.)

It's probably the touchpad - commonly used buttons quit working after a while. If not, then it's the electronic control board.

that is the fault code indicating the button is stuck. the touchpad must be replaced. the lock light indicated two or more buttons activated at same time

holding the button for four seconds will not do it, you have to hold it until the light stops blinking and
will go back to normal, normall takes more than four seconds to unlock the unit, this is something
the sears repair techs know becouse the are trained on all this things but, they will not share this things, becouse thats how they make money

Actually, the button order to put it in a diagnostic cycle and clear the blinking clean light on the gu2500 is HEATED DRY, NORMAL, HEATED DRY, NORMAL not the other way around as Iden had posted.

I too had Flashing Clean light and only responded to Cancel light by trying to drain. Whirlpool Model DU1145. I too got problem to clear by pushing High temp,Heated dry, High temp and Heated dry. All lights on display lit up then it went through sequences of all cycles.
