My dishwasher runs 2 cycles and quits. The clean light flashes 7 times. I've run the diagnostics to reset program. Rerun Dishwasher, same thing, washer quits after second cycle. Replaced circuit board, no help. Checked fuse and door latch switches for continuity, OK. Water temp in washer tub checks 120F +. Replaced control panel for mechanical reasons only. I'm out of fixes.
Hope you might have a fix for this problem.
Note dishwasher 8 yrs old.
ANSWER Hello Bud,
The clean light blinking 7 times is a fault code for the water heating circuit on board the unit. If the control doesn't see a predetermined increase of temperature in a set amount of time, the code will flash. First off, be sure you always run the hot water at the sink before starting a cycle to shorten the wash cycle. The most probable cause of this fault code is the heating element going open. Other possible causes are the door switch 8269209, the control board 8564543, the Hi-limit thermostat 661566, and the wiring harness. Of course the first thing I would recommend is to visually inspect the heating element Heating element kit- This dishwasher heating element is for stainless steel tubs only. Includes a new computer board that needs to be replaced along with the element. For plastic tubs use W10518394. Part Number: 8194200 . If it has burned in to of course it will need replacement. If there is a white place, or much lighter place present it will need to be tested to ensure your not replacing a good part. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html . The wiring diagram should be found behind the kick panel and will guide you to the fore-mentioned components which you may need to test. After repair you will also have to place the unit into the diagnostic mode to reset the control so it can run through cycles again. This procedure is as follows: On the control panel....heated dry,normal,heated dry,normal - OR - High temp,air dry,high temp,air dry. These keys must be pressed within 10 seconds to set the control into diagnostics. At this point you can allow it to go all the way through the self-diagnostic cycle or you can press cancel. Sure hope this helps you solve your problem!
