Kenmore portable dishwasher making loud grinding noise

I bought a Kenmore portable dishwasher used. I have no idea how old it is or where to find the model number on it. It recently started making a loud grinding noise after the top wash arm fell off during a cycle. We reattatched the arm and cleaned out the filter. We tried getting to the pump to check and see if anything is caught in it but we can't figure out how to get to it and what it looks like. The motor appears to be working properly, it spins easily by hand. Other than the noise it seems to be working right. What do you think the problem is, can we fix it ourselves, and how much will it cost if we have to replace anything?

    I also have a portable kenmore that is making the same noise. It will let the water in and pump it out, but does not pump the water to wash.

SOURCE: Diswasher motor making noise during wash cycle

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.

We've had a similar problem. A banshee screaming noise that's makes the skin crawl. Since our machine is well out of warranty I took the insides apart and found only a few cherry pits. (Lesson learned, always scrape your dishes before loading.) We covered out ears for a few minutes and the bad, bad noise went away. But the noise came back, it didn't stay away.. So here's what I found with more tinkering.

1. Problem: Small hard things can get lodged in the food mill/grinder assembly at the bottom of the dishwasher tub. It's there to cut up the big chus of organic matter I presume.Today I found a thin piece of plastic about an 1" long that got caught and was resisting being ground(even though we know resistance is futile) by the grinder thing. Anyway, I took the offending piece out, put it back together and the machine is working fine. I have a hunch that the first instance may have been one of those stray cherry pits that broke up enough to get caught.

2. Solution: take apart inside assemblies to get down to the "foodmill" like thingie and see if there's something hard organic or unorganic causing the noise. Discard. Put back together and hope that solves it. (It did for our machine)

3. What's needed? Good knees or a decent knee pad and a few simple tools as follows:
A. 1- medium flat blade screwdriver
B. 2- TORX screwdrivers, # T-15 and T-20, or equivalent bits for a portable electric drill/screwdriver.
C. Small pair of regular pliers or simialr tool.
D. Muttering under your breath like Fred Flintstone, or not.

4. Process:
Take out the water jet assembly. It is held by a clip at the back and top. Use the screwdriver to pry the tabs away from the clips, then pull the assembly out at the bottom where it connects. It's a simple slide in/out fit. The bottom whirlygig water jet is fastened with a threaded cap that can be removed with the pliers. (BTW, this can get clogged with gunk. while you have it of check for gunk. Then, keeping track, remove the remaining hardware with the TORX #T-20 screwdriver until you get to a round black piece. The black piece has to come off before you can remove the piece with the filter and grinding screen. Use the #T-15 bit for removal of the black piece. Then remove the rest 'till you see a "blade". Hopefully in that process, whatever was causing "the noise" will fall out and you can discard it. Observe how gross it is in there, shudder, and begin the process in reverse.

I do have some pictures of the process in stages if you want. E-mail me at: gpfn47atyahoo.ca (note: please use the "@" symbol to replace the "at")
Well, that's it. I hope it helps someone.
Have a Blessed New Year!

SOURCE: the top water spinner arm fell off, how to get it

This just happened to me. The spinner arm fell off. It left behind two pieces of plastic attached to the roof of the machine: a grey sunburst shape, and within that, a white circle with two prongs. It looks like the spinner arm should snap onto the white circle with prongs . . . but you can't just press it back on, because there is no resistance on the other side and the white circle just becomes displaced instead of snapping together.

But the good news is that the grey sunburst screws on and off! Unscrew it until it comes free from the roof of your machine. Now snap the white circle and the spinner arm together, with the grey sunburst between them. Give it a test spin to make sure it's all together and working, and then screw the whole assembly back onto the roof of your dishwasher.

Apologies for the lack of pictures . . . this must sound crazy to anyone who's not looking at what I'm looking at--but it worked!

When washer is started make loud grinding noise


Very likely the bearings in the motor have begun to fail. You can replace the motor, but for a 15 year old DW, sometimes it makes better sense to just buy a new one. Depends on the features the old DW has, vs new, vs motor replacement cost.

Reply back and we can you more.

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.

Kenmore Elite 137889, grinding noise


If the noise is like a shaking of rattling , like coins being shaked , then it is an object trapped inside the tub.

If instead the noise is a loud grinding , that may get louder on high speed, then it is usually a bad drum bearing.

The drum bearing is replaced by accessing the bottom side of the washer, and is a not a simple repair.

Load grinding noise, like the engine is working too hard.


Most likely the motor/pump assembly is worn out and grinding. If the machine is less than five years old it is under warranty. If over five years old, the repair part alone is about $150 not including labor.

Dishwasher making loud noise


Newer washers are designed with a food grinder inside to help grind up large pieces of food. What you are hearing is the grinder doing its job. You do not need to worry about the noise. It should go away after a while as the food particle is ground up.

Kenmore elite dishwasher noise


I had the same problem where rubber gasket that seals the motor bearings leaked water into the bearing and rusted out the bearing.

I scrapped the motor into every little pieces and extracted the bearing and just replace it. Now it is quiet as a mouse.

You need a bearing puller to get the bearing out for about $20 and the bearing is $6.
During the repair i slightly bent the shaft and i didn't straightened it properly so it wobbles a bit. But it works and if really quiet.
