Whirlpool D/W DU1055XTPQ3, Clean light will not stop flashing

A new cycle cannot be initiated because the Clean light will not stop flashing at the end of the cycle after opening the door.......even if the power is turned off and then back on. I found that one heater leg had a leak, which burnt off the connection...so I filed the end of the heater tab, repaired the leak, and installed a new wire-connector. The heater reads 10 ohms so I assume it is OK. Repairing the heater connection did not resolve the problem. When testing the functions, the Cancel/drain function still works when its button is pushed, but the Clean light never does stop flashing.I tested both door switches and they are OK, so I ordered and installed a new board. The new board did not help. Now I am stumped. Can you help me?

    I have received a reply asking if I need a service manual. No, I need the advice of someone who has seen this problem before and can advise me which part of the circuit to troubleshoot next. I am a journeyman service tech with 39 years experience and just want to expedite the repair as fast and inexpensively as possible for my customer!

  • Marit Jan 01, 2009

    This problem did occur after a major power failure lasting about 6 hours. However, the voltage (125V) has been proven again and again to be nominal, and the fault is not going away even after turning the power on and off many times, i.e., it will not cancel off even after the Cancel/drain button is pushed and the door has been opened and closed many times.thanks anyone for your input.

  • Marit Jan 01, 2009

    There is no error message, all that I see is a Clean light flashing, which indicates that the wash cycle is over...but then the Clean light will not remove itself and allow initiation of a new wash cycle.In other words the board seems to be frozen on Clean, and will not advance to a new cycle no matter what is attempted...very frustrating. Again...new board no help. Thanks for any input.

    Happy New Year everyone! I only have a few days left before I am obliged to order a service manual for the dishwasher, with no guarantee then that the problem will be resolved, or I will have to tell my customer to buy a new dishwasher (the problem machine is 5 years old).......I would not order another new board for it unless one of you experts tell me it must be the board (again?!) Please see previous posts. Any input is appreciated.

  • Marit Jan 02, 2009

    I have been advised to air-dry the dishwasher sump. I fail to see the connection between a flashing Clean warning light, and a damp sump. There is no excessive water in the dishwasher because as I mentioned, the Cancel/Drain button still works when pushed, (i.e. the 2-minute cancel/drain cycle is activated OK), and if water is manually added to the tub it drains fine. The original problem is that the flashing "Clean" light will not go out. Ever. And so a new wash cycle cannot be initiated. A new board did not resolve the problem. Any input will be appreciated.

  • Marit Jan 02, 2009

    I have been advised on this site to replace the heater, or to expect that the problem is in the heater circuit. This has been my instinct for a while, and was hoping to get confirmation..........thank you. (Although I tested the heater at 10 ohms early-on in the diagnosis, one of the heater connections was burnt off and I did repair it). I have ordered a heater, which should arrive early next week, and will let you all know if this resolves the problem. Any further input will be appreciated.

  • Marit Jan 19, 2009

    This problem was resolved by Dipu007.
    The Clean light was flashing because a heater connection had failed, and the dishwasher had gone into Diagnostic Mode. Once the heater connection was repaired and the Diagnostic Mode was cancelled using the correct button sequence, the machine returned to normal operation. Thank you Dipu007!

A clean indicator that flashes/blinks 7 times and then repeats, indicates a problem in the dishwasher which should be investigated and not just the control 'reset'! That is why the control will not let the dishwasher start once such a condition is detected.
If the dishwasher's electronic control doesn't detect a water temperature increase during the main wash cycle, that symptom can occur. No water temperature increase could be caused by a problem in the heater element, its in-line thermostat, the related wiring or a problem in the electronic control.
It is also possible just the washer not spraying properly (possibly from blockage in the filter or problem in the pump), the dishwasher not filling sufficiently or draining prematurely or even a problem in the door latching mechanism's switch(es) could cause it.

error display may have to be cleared from the control manually. That can usually be done by putting the unit into diagnostic mode by pressing the key sequence 'Heated Dry, Normal, Heated Dry, Normal' and then pressing cancel.

Hi, I see that you have problems..! I have seen this problem before in some whirlpool dishwashers. I see you have replaced the main P.C.B. and still no luck! I use to work for whirlpool uk and remember a few things you could try! If the heater meggers ok then i dont really see a problem other than if it goes open circuit during the wash programe but i can see yours is not even reaching the wash cycle. I take it you have tested the heater for insulation?? Does the wash pump look ok? Is there a over fill float switch in the bottom of the diswasher? If this is activated then the new programme will not start as it will think that is has over filled and the base is full of water!?!? Very common problem.) I would also check the wiring harness in the door panel as these have a very good way of breaking and you not finding them. I would first check the over fill switch in the bottom of the dishwasher first as this indicates this kind of problem..
Good luck.....................

After the power outage, the power came back on and the machine got hit with a surge. The surge welded the contacts closed on the door interlock switch so the clean light is staying on because it doesn't "think" the door has been opened and the clean dishes unloaded. Pull a lead off of the door switch (switches if it has two) and see if that clears it out. You should be able to run a cycle after doing that but only once before the same thing happens again until you replace the door switch

If the Clean light is flashing non-stop with no evident #, it is the heater or heater circuit that has failed.

Hi and welcome to FixYa,

Initially, on most washers, clean would refer to the drain system normally found at the very bottom accessible through the removal of the bottom plate / kick panel. Pls try:

  • cleaning the drain system which would include the filter, sump/bowl, impeller, pump and the hose (check also for kinks). Not that difficult but messy;
  • additionally, you may want to force dry the bottom area with a can of compressed air, a compressor, a hair dryer, a ventilator/electric fan.
This should of course be done including the drying with the unit unplug from the mains.

Good luck and Thank you for using FixYa. Happy New Year.

    Forced/Air drying would not cost any compared to "A new board did not resolve the problem". And it would eliminate just one possibility. Even if it has no positive results, you were able to eliminate that as a probable fault.

    Cheers and Happy New Year.

Hi
The Maytag diagnostic tips manuals says: 

During Automatic Function Test, if a fault has been detected, the test will abort and 2 LED's will begin to flash. The CLEAN LED and: 

Keypad 2 LED ("light wash") - Motor - low current. 

I'd have someone check the voltage on the circuit your dishwasher is attached to make sure it is a at 120volts. Sounds like you have a brown-out voltage issue. Good Luck!

Kenmore: Whirlpool
All serial codes.


Whirlpool has issued a service bulletin on this problem. Seems the heater fault-detection circuit is buggy. The condition can also apply to a dishwasher that has had the electronic control replaced.
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.


GORY DETAILS:
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.
The detection described above is ignored if the temperature is out of the normal temperature range of 64°F to 160°F during this heat period. This thermistor temperature test is not done to increase water temperature for better washability, but to only assure that the heater is functioning.
Proper incoming water temperatures should be between 120°F to 140°F.


CORRECTIVE ACTION:
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.

Clean light is flashing 7 times, stops and flashes again. Can't make it started anymore.


my whirlpool is doing the same thing. I'm trying to find a wiring diagram with not much luck. A work around I use is to turn the breaker on the fuse box off for 5 seconds then back on. The dishwasher then works for one cycle.

The "clean" light blinks


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.

This is flashing due to a fault with the water heating. Here is a link to instructions on how to reset the control so you can use the dishwasher and what may have caused the failure. Let me know if it was helpful.

The "clean" button is flashing & none of the other cycles work.


heated dry and high temp wash
toggle till all the lights light up

you should be able to turn dishwasher back on
you probably have a bad heater

Clean light flashes 7 times


try doing button setting change from "Hi-Temp Wash - Normal - Hi-Temp Wash - Normal" sequence of button selections. This must occur within 6 seconds and initiates an internal diagnosis of the machine.
The process runs for about 19 min. and shuts off
During the process several LED's light up and several funtions start and stop.
If the machine has no broken systems, you should be able to open the door add some soap and the usual dirty dishes and carry on with normal operation. this is the method to reset the machine.
Most likely is that there were suds in the last cycle or the door doesn't close smoothly.

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.

Light flashing


There was a problem with the heating cycle , the seven flashes indicates the temp never reached the setting. You can try running a service cycle that will reset the control, then try running a normal cycle if it stops agin will have to find the part causing the trouble believe they actually came out with a revised heating element on this. to run service cycle press heated dry , normal, heated dry, normal within six sec then the d/w should step through a service cycle.
