FIXED Clean light flashes 7 times.

[Neil Wright]

also...what is the "rapid advance cycle"?

cycle JUST ended, with "clean" light on and "sanitized" light blinking (all normal, right?). heat and some remaining steam came out upon opening the door. everything looks nice and clean. i touched the heating element and it was NOT hot and parts of it were still wet (indicating the element isn't heating?)

ok...here's the recap:
1. i had the "clean light 7x flashing" problem, which resulted in not-very-clean dishes.
2. i did NOT check the heating element as it looks fine (i.e. no ash or grey coloring), and the interior of the machine was always very warm upon ending a cycle.
3. replaced the control board. machine worked fine for a few cycles, then the flashing clean light problem came back.
4. reset unit as instructed and machine again worked fine for a few cycles, only for flashing clean light to resurface.
5. i got used to simply resetting every time i used the machine, which worked out, until the touch panel started lighting up strangely and i couldn't even reset it any longer.
6. replaced the touch panel and reset the machine. all lights on touch panel work fine.
7. we are back to square one: the machine works fine for a few cylces then reverts to the flashing clean light and dirty dishes.
8. any ideas? desperation is setting in...

i just saw this from the service notice related to the "clean light 7x flashing" problem:
"Once a heater fault is detected and the condition resolved
the electronic control must be reset by initiating a service
diagnostic cycle. NOTE: Using the RAPID ADVANCE
CYCLE will cause the blinking LED condition to reoccur
because there is insufficient time to heat the water.
Check the product Tech Sheet for the correct cycle
sequence.

the $64,000 question: what is the "service diagnostic cycle"? maybe i haven't reset the unit properly after having installed either the control panel or the touch pad? HEEEELLLLLPPPPP!

Your tech. data sheet will show you the keypads to press in sequence to enter the diagnostics cycle, did you find your tech. data sheet? Its located behind the bottom access panel.

DEPENDING UPON YOUR KEYPAD OPTION BUTTONS, push this key button sequence: HIGH TEMP SCRUB > AIR DRY > HIGH TEMP SCRUB > AIR DRY OR SANI RINSE> AIR DRY> SANI RINSE> AIR DRY. Let it run all the way through!

rapid advance cycle just quickly advances the diagnostics cycle, you DON'T want to do that. Just let it run the complete diagnostics cycle till it ends on its own.

Like I mentioned in post#31 of this thread:

You would need a multimeter to ohm the heating element first, as the 7 clean lights blinking is caused by a heating circuit failure. Make sure your breaker to the dishwasher is off and stays off when removing you dishwasher and ohm testing the heating element.

Here's the heating element for your model you can order if needed:
Heating Element WPW10082892


You'll need to pull the dishwasher out first.

If the heating element ohm tests good, The only other possibly could be the pump motor assembly not circulating the water properly, thus making it do the 7 clean light flashes.

Check your chopper screen, it may be clogged, and your check valve too.

Watch this video first:

Here's the chopper blade screen assembly for your model:
Food Chopper Assembly W10083957V


Here's the video to check/change it:

Here's the check valve for your model:
Check Valve WP8268375

Checking all this will keep you up most of the night, make a pot of coffee and go at it.

OR start fresh in the morning.

thanks jake! i'll run the sequence first. when i first started on this project, i also cleaned out the drain. chopper, etc., so that step is taken care of. so basically, there are only five possible causes at this time:
1. bad control panel...fixed.
2. bad touchpad...fixed.
3. clogged drain/chopper...clean.
4. bad heating element...on the list to check with ohm meter
5. diagnostic service cycle never implemented correctly...will do now with fingers crossed.

i'll let you know how it goes. thanks again!!!

 

[Jake]

Ok Neil, yes let us know what you find.

after finally removing the unit, it was pretty obvious why my heating element wasn't heating. not sure why this happened, i only know that it did! by the way...GREAT packaging on the replacement heating element (and with biodedegadable packing no less (none of that popcorn cr*p)!

 

[Jake]

Yup, seen that many times, new heating element time, and you'll need to cut the bad spot off that burnt wire and re-splice it with a new female electrical terminal.

The most reason why this happens is that female electrical terminal is loose and starts arcing over time, so make sure the new female electrical terminal is very tight and snug on the male heating element electrical terminal.

I have KitchenAid Dishwasher Model KUDP01FLSS6. It has experienced 7 clean blinking lights. I reset the control panel by pressing High Temp-Sani Rinse twice and follow by Clean. However the problem always come back. I have replaced the heating element, the thermistor, and the hi limit thermostat, run it again, and the clean light blinking always come up after less than 10 min run. What could be the problem? Do I need to replace the controller board? What other things I need to check? The dishwasher is about 13 years old but it's in good condition other than the clean blinking light problem.

Note: the old thermistor, thermostat and the heating element were all good. I measured the resistance of the thermistor and the heating element before replaced them with the new one.
