..which indicates a heating problem. I've ran hot water before starting the dishwasher. I've reset using the keypad dance sequence. Still trips over to the flashing clean light. After I've reset the machine & opened the door, the dishes appear to be wet - and the water appears to be only warm/borderline hot - not as hot as I'd like to think would be necessary to clean dishes.
I'm not sure what to test first.. I'm guessing the heating element - but I'm not sure where it's at or what to do to test it. After browsing the net, I've seen various Kenmore model 665 owners reporting the same problem with several of the repairs ending up being with their motors or with their keypads, which is worrisome to say the least.

Re: Whirlpool DU1050 / Clean light flashes 7 times
Cmattson, This problem has been a real pain for owners of this model as well as us techs who repair them. There are a lot of things to check to get to the right problem. First, the water entering the dishwasher should be no less than 120 degrees. During the first 8 minutes of the initial wash cycle, the heater should be on. You can check this by dropping the toe panel and doing some tests. The element will be in the rear, so it can be difficult to get at unless you can pull the unit out some. Make sure the wires to the heating element are on. With a meter, you should be able to verify that the heater is receiving 120V during the first 8 minutes. The main board monitors the thermistor to see if there has been a rise of 4 degrees with water that enters below 110 degrees and 2 degrees with water that enters above 110 degrees. If it does not see this, it will drain and flash the clean light. The element itself should ohm out at 10 to 35 ohms. Other things you might have to check; The heater runs on the nuetral side of the door switch so you want to make sure the d/w is level and the door is closing properly. If the left door switch is not making contact, the element will not heat. Make sure all the harnesses are on tight on the control board. I have found in most of my calls on this problem it was a faulty heater. I've only had one case of a faulty thermistor. Best of luck on this..

The clean light flashing 7 times is an error code indicating an issue with the wash temperature. If the control does not detect a 4*F temperature rise in the main wash cycle, it will display the fault as the clean light flashing 7 times. There are several things that could cause the water not to heat, including the water being too hot coming in, an open door switch, or a faulty component in the heater circuit. The most common cause is the door switch not closing properly. This can be due to a loading issue or a latch issue. If upon visual inspection of the heating element no obvious defects are found, I would recommend resetting the control and running another cycle, paying close attention to door closure. If the light begins flashing again, you likely have a component failure. The heat circuit consists of several components including the element, control, door switch and tub thermostat(s). Reset the control by pressing teh following buttons within 5 seconds.

for using FixYa. If the clean light flashes 7 times, pauses, and then repeats this occurs 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
temp wash -heated
do rate the solution if the issue is resolved or post a comment for further
assistance. Thanks Rylee

ok well usually it is not sensing a temperature change in the water or
not getting hot enough. so you can reset the dishwasher and try running
the hot water in the sink before starting the dishwasher. if it fails
again there is a heating element and control board kit that would need to be installed. you can reset the dishwasher by pushing "high temp wash" and "heated dry" back and forth until all the lights light up then you can hit the cancel and drain button twice.. put detergent in and run it.
That means the control sensed that the heater in the d/w did not operate 3 times in a row. so the unit locks out. First remove the kick plate and you may have to pull the unit out from under the cab, but check your heater. use a meter to see if it reads open, if so order a heater assy it will come with a new control replace it to. If your heater checks good press in sequence normal wash , heat dry ,normal wash,heat dry , normal wash , heat dry three times within 6 sec all the lights will come on then hit cancel. What that did is reset the control and clear that fault. Keep in mind that d/w does not heat it's own water your incoming water temp should be 120. the d/w will maintain that temp. when starting your d/w first turn on your hot water till it gets hot then start your d/w this insures your unit fills with hot water and not cold
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.
A blinking clean light that flashes 7 times and cannot be reset, occurs when the electronic control does not detect a water temperature increase during the main wash. This could be an indication of a failed heating element, in line thermostat, electronic control board and/or wiring. This problem can also occur if the main wash pump becomes clogged and it not spraying sufficiently. I hope this helps you.
PS A faulty door latch can also cause this error code.
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 eletronic 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.
*Some actual investigation should be undertaken to isolate and correct the cause of the symptom.*
Once corrected, the 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.
