Kenmore dishwasher - Cycle doesn't END

11 posts in this topic

I have a Kenmore dishwasher that seems to be "stuck" in the washing mode.  The dishwasher has the washing and sensing lights on, but doesn't move from there.   ANY IDEAS WHAT COULD BE CAUSING THIS PROBLEM?

Need the model number since this could be any brand, Sears makes nothing, and need to know exactly which cycle or cycles this is happening in.  Which lights are on.  And make sure you are have  heated dry on or the dishwasher will never advance if the water cannot heat in the pots and pans cycle if the heating element is turned off.  If this is on sounds like you might have a bad tub thermostat that reads the temperature of the water and cuts the power to the timer until the water reaches the thermostat temperature.

the model number is 66516512200.  I normally use the "SMART WASH" cycle with "AIR DRY."  The lights that remain on are the "washing" and "sensing".    Let me know if this helps.

This is a Whirlpool dishwasher with the Kenmore name on it.  Try it without the air dry because the water cannot heat with the heater turned off.  This has to heat the water to probably around 140 to 160 degrees and the unit will never advance till the water reaches the temperature of the tub thermostat.  If this does not solve the problem, you might have a defective thermostat, but turn the heater on and try again.

The problem persists even after turning off the air dry.  Is there a way to find out whether its definately the thermostat?

You could check this with an ohm meter to see if it is bad, is usually on the bottom of the tub toward the front of the unit behind the toe panel.  With the power off to the d/w that is.

Wallstreet,  you are going to have to remove the bottom panel.   The thermostat that Pegi is talking about is mounted to the bottom of the tub on the right side.   It's normally closed and will open at around 175 degrees.  So if you ohm it out,  it should show continuity on the meter.  I suggest that you also check the thermistor on this unit,  it's located on the  bottom of the sump on the right side as you look at it from the front.  Usually in the case that you described,  this thermistor is the culprit.  You can ohm this out too,   usually reading 48 to 52K at room temp.  Should this check good you could have an issue of the board not reading the thermistor.  Checking this can get invovled.  Hope this helps...Sears don't make anything,  but man they sure sell a lot of stuff....Ron

Just a lowly grasshopper, but shouldn't mrwallstreet verify that the heating element is actually heating the water?  I believe he would get the same  indication (stuck in cycle) if the water just didn't reach the temp required by the thermostat.  Three days ago I had a teflon cooking spoon escape from its confines and melted to the element. I removed the element and tried to clean it. No hope. So I put it back, did not connect the wires, turned off the water heating option, ran the d/w on normal cycle and got as far as the final rinse which automatically heats the water. At which point it stuck just rinsing and rinsing and rinsing. I went fast forward to the quick rinse cycle which sensed a full tub and drained it. This is while the new element is on order. Just an observation.

Yes, this is a good point, when the dishwasher is running, open the door and see if you can tell if the heating element on the bottom of the tub is in fact heating. If not, this could very well be your problem.  How old is this unit??  There are service bulletins out that address a defective element issue, but we have no way to cross a Sears badged unit to Whhirlpool since there is no cross over.
