Question about Kenmore 16973 Stainless Steel Dishwasher

Dishwasher makes a humming sound, but does not flow water to jets

Problem Statement - Dishwasher makes a humming sound, but does not flow water through the wash jets.


1. Dishwasher control panel functions - Entire dishwasher cycle will run.

2. Dishwasher fills - float works.

3. Dishwasher empties and fills during cycles.

4. Dishwasher heats at end.

5. Dishes are dry and soap remains in tray - Hence - my original problem statement description.

Investigations Round 1:

1 a. I disassembled and reassembled the interior wash assembly to check for damage or debris. None found. Screens are in good shape.

1b. It was hot and I needed to get the manuals - I stopped. Washed dishes by hand for 3 weeks (Yuck) - tonight new investigations:

Investigations Round 2:

2.a Removed dishwasher from counter enclosure - Uh oh it appears that I have a mouse that likes fried chicken bones - might be a country mouse.... note to self, get a trap and a bone for it.

2b. After some study, I think I have a good idea of the things underneath.

2c. disconnected the drainage line - no debris or plastic - felt into the pump area... no obvious damage, can spin whatever you call a pump's little blades on spindle thingy.

2d. Took off the motor and with it the white assembly embedded into it. Removed (pump well?) screen. No debris.

2e. The little transmission like gear at bottom of well is not damaged, appears to turn fine without any resistance. (maybe it shouldn't?).

2f. Looking at motor assembly - do not see damage that is obvious - but I'm clueless - doesn't smell burnt.

2g. Looking at the white pump wheel assembly thing... it turns, a little resistance... not sure if I felt a little grinding at the beginning - may have but wasn't sure what it should feel like. Tried to remove this part... couldn't and didn't want to force it.

I stopped here - re-assembled everything - gave the motor a light "technical tap" with my hammer. - re-installed in counter. Tested... still same problem (so much for the tap).

My questions / thoughts - is it likely that the motor is just broken? If so, is the white pump assembly thing embedded within the motor a removable thing? or does all come together? - Maybe white pump assembly wheel shouldn't spin freely... not sure about that.

How can I fix this without buying parts that are the wrong ones.

Hopefully one of you very smart guys can help me out. If so, it will be very very much appreciated.

Sincerely,

Michelle

SOURCE: Kenmore dishwasher 58715142400 fills but doesn't wash

Motor has gone out..just like mine...Make sure u have voltage going to the motor, (disconnect the plug from the motor) and use an electric meter to make sure you have voltage going to the motor. If so the motor has either gone out or has been blocked by something! If no noise except clicking then motor has gone out. Looking at about $150 for motor.

SOURCE: Kenmore Elite dishwasher will not dissolve soap or wash well.

Temperature should be 140F. and the units heater should energize during fill to achieve this.

I bougt a kenmore 18" dishwasher, the dishwasher


Hello,
Sounds like the water is either off or a flood safe hose is being used. The valve is energized and water is not flowing in, that is what the humming noise is.

Dishwasher does not fill with water. It hums as if it is trying to work.


If there is water in your inlet and on switch of program there is water coming into the washer, it is possible that the Hum you are hearing is the inlet valve/pressure pump that is not activating.
It might be getting warm if humming for a while and you can check this out. Remove the unit and checkit out onthe table by applying voltage for the water flow or pumping. Dirt accumulation can make it stuck and if not replace .

Water not flowing


Be sure that the water supply valve is turned on. If it is and the water line to the dishwasher is not obstructed, the water inlet valve on the dishwasher is bad.

No water


Check the incoming water to the dishwasher. If the filter is clogged clean it and re fix. Strainer is located on the machine inlet junction where the hose is fitted.

The humming sound is due to motor running without water. When you rectify the inlet flow fault, pour additional water manually into the wash chamber and run the cycle. This to remove trapped air in the pump due to dry run.

Kenmore elite not washing dishes


Sounds like the motor is stuck. If your careful you can unplug the dishwasher or turn the breaker off, take the bottom panel off and reach in with your finger and spin the motor assembly.

Dishwasher motor makes like a grinding noise on start up


Hi. This grinding or hum can be associated with internal electric motor failure. the grinding and humming sounds are warning signs that will ultimately, lead to total failure.The actual term we in the industry use is A.C. hum. This will occur when the internal electric motor windings begin to break apart from the center housing inside the motor casing. this will disrupt the current flow, causing over heating. the grinding is because of the alignment that has been disturbed as well. The solution is to prepare for the replacement of the electrical motor or, you can repair it.

please rate and have a great day.

Dishwasher not moving past sensing cycle


humming noise sounds like a solenoid is not snapping in, this is not something that the average or even above average homeowner can fix. Solenoids go bad, they are a moving part that are activated by electricity, can be dangerous to mess with as water and electricity don't mix. Get a repairman or get a new one.

My dishwasher is making a humming sound and does not rinse?


A humming sound can be a failing wash motor (that drives the water pump) or it can be as simple as a blockage in the the pump area beneath the lower spray arm, under the filter.
Remove the spray arm and the filter top (screws will need to be removed)
Use a flashlight and inspect all over the sump area for debris that is blocking/jamming the impeller area. Reasemble and test with a short cycle.
If the dishwasher continues to make the same humming, it is time to replace the wash pump.
Good Luck! Post back here if you would like more guidance.
