Stuck motor? A piece of *something* has jammed my dishwasher. It will fill/empty but the sprayer/grinder motor won't run. There is just a buzzing noise. How can I open up the motor and extract whatever is jamming it? Thanks

    Well, I followed your excellent advice and found the shaft of the grinder had snapped and a pit was lodged under the blade. I replaced the grinder and put everything back together but the problem persists. I am still hearing a humming noise when the wash cycle should be running (after the water has filled). Are there any further ideas about what might be wrong? Is there something that needs to be "reset"? Is there a fuse that is blown? Is the motor broken? Any further ideas would be greatly appreciated. Thank you!

I got a screw stuck in the bigger of the two holes behind the chopper blade. When I look down in the hole I can see the screw but cannot reach it with anything. IT looks like there is a second chopper blade in the housing and the screw is wedged between that and the housing. How do I get the entire assembly out like you did in the picture?

Catriver, Great advise and excellent instructions. I had the exact same problem. Once I removed the chopper housing, I noticed the chipper rotated a little snug then got tougher. A couple turns clockwise and counter clockwise and free as a bird.Maybe somenting gooey was stuck.

One thing I did notice after the repair, when motor started, it was growling but quickly stopped. Could this mean the motor assembly is starting to wear??? Is this an easy fix?? What parts are needed and any idea on the approximate expense???

Considering all I have read on the poor service of the Kenmore, I'll look elsewhere next time. 2 years 2 months and I have this problem. Go figure. Thanks for all your help!!!!

Bert, to get to the sump and chopper assy. First remove the lower spray arm by holding the top tab and turning the spray arm off. Next grab a hold of the rear feed and turn it to the right until it unsnaps from the rear feed assy. Now you remove the filter and accumulator assy. It has torq screws, remove and lift off. Now the chopper cover will be on the left, one torq screw and it will lift off exposing the chopper blade. This is probably where it's jammed. Look at the attached pics. It will help you. Catriver.

    Take your time and observe what you are doing so you can reverse the steps, this will go real easy. Clean the chopper screen to get good water flow to the upper spray arms.

    bert, first check to see if both wires are on the capacitor. The capacitor is mounted to the motor toward the back side. If one of the wires came off, your motor won't run. You may have to pull the dishwasher out. The chopper blade should should rotate with moderate force. If it is difficult to rotate you may need a pump motor assy. The fact that you are hearing the humming tells me that you are getting power to the motor. You can ohm the motor windings. Run windings should ohm at 3 to 7 ohms. Have the capacitor leads disconnected when ohming the motor windings. That chopper screen fits into grooves in that inlet cover, make sure you have that set in right. When all said and done bert, without being there, sounds like the motor is fried. Catriver.

What is the float switch


I have no real experience with float switches on dishwashers, but have with some in humidifiers. It's a piece of styrofoam on a narrow metal stick that lifts when the appliance fills with water & lowers when the water empties. If this gets stuck on something, like a dishwasher rack, the unit won't fill or empty the water & the cycles won't work properly. Take a look & see if there is such a thing hung up somewhere in the dishwasher. If you can loosen it, your dishwasher should work again.

Why is my dishwasher making a buzzing noise? It is almost 2 years old and is a GE brand we got from Sears. It is still cleaning and filling and emptying properly, but the buzzing noise is driving me...


Sounds like a noisy circulation pump motor. As an Engineer, I would treat any abnormal noise seriously; the motor may require examination and possibly a new start capacitor fitting? or it may be loose or have a problem with its impeller, etc. Or it could possibly be a relay for the heating element is noisy. Either way, abnormal noises are unusual, and dishwashers need to be 100% reliable as they are often used unattended or overnight and any problem might indicate a possible fire risk. Sorry to be so heavy - is the machine subject to any guarantees or extended insurance etc? Some have 5 year guarantees. Whatever, I would call an engineer out to have it checked over.

Kenmore Ultrawash Quiet Guard 5 making buzzing/grinding noise


I have a very similar dishwasher, with a very similar problem. I fixed it by removing debris from the water evacuator pump located towards the front of the bottom of the machine (the last motor before the drain hose. In my case, grape stems had clogged it up. Once emptied, it purrs once again. NOTE: don't disassemble the motor, just flush it out, there is an o-ring gasket that is a bear to re-install.

WASHER DOES NOT TURN


Sounds like the motor has frozen. Try to work the drum loose from the bottom (empty and unplugged) it just might be jammed from a pen or similar item lodged inside (someone not emptying their pockets). Since its buzzing (its the motor TRYING to move the drum) it has to be jammed from something. Rarely it could be a bearing locked up in either the drum or the motor itself though its unlikely.

It may sound loud and like something is terrably wrong - but when we researched and took the pieces of the sprayer arm out all the way down to the drain - we found 2 small pieces of nut shells - that's it ! They were making the dishwasher sound as if it had something really wrong with it. We removed the nut shells - put all the parts back together - it runs perfect!! Just remember to place the parts and screws in the order they came out - so you put it back together correctly
