Question about Kenmore Dishwashers

1 Answer

My Kenmore Ultra Wash dishwasher (665.16879) Is not filling completely. The water does not reach the heating element. The float is not stuck. The upper arm does not rotate and only dribbles water. No water comes out of the outlet at the top of the washer tub. HISTORY: A month ago I disassembled everything I could on the inside of the tub because it wasn't cleaning well and I noticed the same problem with the arms. At the time I did not check if the water level was low as it is now. It may have been, and I just didn't notice. Turns out the chopper assembly was completely plugged. After cleaning and reassembly the washer worked like new for a month.

    Thanks for getting back to me cmmiuser01. The water does not drain as you mentioned above. It simply is not fully filling. The check valve is seated properly. I removed it and it looks like new. I also noticed that the chopper was plugged up again.

  • kjdupuis Nov 16, 2010

    Also, I tested the electrical contacts on the fill valve for continuity. The test was negative

  • kjdupuis Nov 16, 2010

    I put it all back together and again, like last month, the upper arm now turns and water comes out of the upper port. I also added water to the tub (after it stopped filling) and it took 3 pints to trip the anti-overflow switch / float. Am I right to assume that when functioning normally the dishwasher fills until this switch is tripped?

    Anyway, I still don't know what's wrong.

    Looking forward to your reply.

    ok, thanks

    So it seems to me that the washer IS filling properly. The water comes to just under the heating element. My research tells me that the element is not normally submerged and that the water is heated as it cascades over the element during the cycle. I had made the wrong assumption that it was meant to be submerged. Since the chopper was fully plugged after only a month, is it possible that the chopper blade needs replacing? Do these normally wear out? Would a plugged chopper cause these problems?

  • kjdupuis Nov 19, 2010

    I will continue to run it. If the problem arises again and the chopper is clogged again, I will change it.

There are two things to check - is it filling first but loosing part of the water through the drain during wash or is not filling up fully at all? Do you hear the drain motor running as well during the wash cycle. (any noises in the drain on sink side?)

Firstly I would suggest you inspect the check valve (item 5) on this diagram. Open the diagram in new window or print for better view by clicking on the selection at the bottom of it.

if the check valve is not sitting properly or is broken then you can have water not being pumped up adequately by the wash pump.

Please post a comment to confirm what you see.

    I have read your comments and will need to understand the sequence of steps involved before getting back to you. I am on the road at the moment and will respond in about 8 hours.

    1. The float circuit is only for protection. As soon as the float lifts it triggers a microswitch which is constantly sensed by the controller and it shuts off the inlet valve and starts the drain motor and shuts off the dishwasher. It has no role to play in filling up the dishwasher normally.

    2. Keep in mind your dishwasher is very smart and it senses the soil in the wash water and adjust wash cycle and water quantity required accordingly. Refer page 7 of the user manual which gives an explanation of the smart wash.

    3. My view is that if the water is not filling adequately the soil sensor is faulty and tricking the controller into stopping water intake early. Alternatively, if the incoming water pressure is not adequate that may reduce the water coming in. I am assuming you are using the hot water connection. Is you hot water system ok?

    4. I am still not sure where the soil sensor is located. It should look something like this. It could be item 46 in the diagram of the tub assembly. You will have to check this out.



    So there are still some possibilities of the water not filling - provided you are sure the hot water system has adequate pressure and the inlet hose is not kinked anywhere.

  • Sam Nov 19, 2010

    I am unclear at this stage if you still have a problem with the dishwasher. I thought I read in one of your recent comments that once you opened and cleaned the chopper a few days back, the water was getting to the top arm.



    If that is the case then I would not be replacing anything. But if the pressure is not there to get the water to the upper arms then the wash pump may be the problem. The chopper is a problem if it is frequently creating a blockage which prevents the water from getting through. In that case you should change it.

Kenmore ultra wash dishwasher gets stuck at 42 on the control panel


Be aware that all (well, almost all) dishwashers have a "thermal hold" period in their cycles. This is the point in the main wash cycle where the heater is turned on to heat the water to the optimum wash temperature (about 150 to 160 deg F), and during this time, the timer will stop advancing. Once the water has reached the desired temperature, the cycle will continue. IF it does not, then you have a water heating problem. This could be caused by a bad heating element, a bad controller, a bad thermostat or temperature sensor.

Float in dishwasher not recognizing water level


Hi. The float sensor is just a fail safe device to prevent the DW from overflowing. I would first check the incoming water pressure and also check the input water valve to make sure that the screen is not clogged. Try running it without the water pre-heat feature also. BTW, it should be connected to the Hot water line.Temp. sensors will cause erratic problems in this case. Hope this helps.

No water is coming in the dishwasher. I can hear the water running, but the water is not coming into the dishwasher


If you can hear the water running - but it's not filling, you most likely have a drain problem, which is being stuck open. Usually the motor kicks in and either pumps the water through the wash arms (during wash cycle) or through the drain (during drain cycle) the switch that/or flap could be stuck on the drain and it is pumping it out the drain all the time instead of the wash arms.

Larry,
The float is generally for overflow conditions and will interrupt power to the fill valve solenoid.
If you are not filling completely in the time allowed by the timer, it is most likely a flow restriction in the water supply. Barring other obvious restrictions, the fill valve has filter screens on the inlet side of the fill valve, which is generally the cause of your symptoms. Be careful if you attempt to clean the screens, as the fill valves are very sensitive to debris, and can become stuck open if sediment gets past the screen. I usually replace the fill valve to avoid future problems.
Hope this helps.

It starts then stops. never completes the cycle. it shuts down. it will drain thats it.


If the cycle didnt complete check the following:

Water-heating cycle
Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

* On some units, the pause is timed and the unit continues after the allotted time.
* On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.


Timer
Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place doing one function continuously the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

Heating element may have burned out. Check water temp during wash--should read between 130 to 140 F.

· Bad wiring to thermistor F4 Fault with water fill (only on machines with level-controlled fill)

Note: Lights blinking, pump running and controls dead indicates an over fill fault 1. Disconnect the power to the unit

2. Remove the lower access panels and check the tray under the dishwasher (you will probably find it is full of water)

3. Use a towel or a sponge to remove the water

4. There is a float that should stop the operation of the dishwasher and run the pump if water is in this tray. Check this pump to see if it is functional

5. Test the dishwasher

6. If there are no leaks from the dishwasher into the pan, check the drain hose under the sink

7. THE DRAIN HOSE MUST RUN UP TO THE TOP OF THE UNDERSIDE OF THE COUNTERTOP THEN DOWN TO THE DRAIN. (If the hose is not set up like this, water from the sink drain will flow into the dishwasher and overfill the tray

*Faults may vary by model. Use this as a general guide.
i think these details would definitely help you.....thank you...

Smelly dishes from Kenmore Ultra Wash


If you post the model number of your dishwasher plus its approximate age (in years) I can help more.

But the most common cause is a weakening pump motor. On many dishwashers, the wash pump motor is also the drain motor. Replacing that motor / pump assembly will solve the problem. While you are replacing the pump, check the heating element to confirm that it is not shorted out or broken.

For now, add a cap full of bleach to the water _after_ the initial dishwasher fill cycle ends and the wash cycle begins. White vinegar would also work, but this will not fix your problem.

Good Luck!

I'm just wondering how much water should be in the dishwasher for proper cleaning? Should it cover the heating element?


Water level can depend on the model and manufacturer. The water will fill to the level of the float switch. This is a plastic looking thing near the front of the dishwasher along the tub bottom that looks like and upside down cup. The water level reaches a point to where the float lifts and activates a cut-off switch which will stop the water from filling, followed by the wash cycle beginning. Now, depending on where the heating element is located, the water level is usually just touching the element and not necessarilty covering it. Does this help you? If you still have questions, let me know.
