HI. the wash impeller is damaged. this will cause much noise during the wash and it will affect the nature of the wash dramatically. this impeller is attached to the circulation motor under the sump. it should be replaced asap, if possible.

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.

Problem is with the main pump motor bearing. Water leaking from the face seal enters the front bearing. After some time, the bearing wears out bringing on the loud noise. The motor is easy to remove but the bearing requires some time to remove. I did not have access to a press so I ground off the bearing an replaced it with a shielded 8mmx22mm type. Grainger p/n 1L001. The part is only $9 compared to over $200 for a replacement motor. It takes some time and disassembly of the dishwasher can be difficult but take your time and be ginger with the parts. The root of the problem seems to be the impeller. It screws onto the motor shaft and seems to work loose after time. Since its tightness compresses the face seal, when it loosens water can seep. No way to lock it in place after tightening. Weak design point.

A loud high pitch whine while running the dishwasher means that there is something caught in the chopper assembly. To get to the chopper assembly you need to take the racks out and take the pump apart from the inside of the dishwasher. The chopper assembly looks like a metal grate with holes in it. And it might not even be stuck in the grate but somewhere in the pump area due to the water being pumped out, so the best idea is to take the whole thing apart and clean everywhere. However I do not recommend doing this unless you are completely certain you will remember where the screws and gaskets go, otherwise you risk damaging your pump or house from a leak or improper installation. You have been warned.

SOURCE: 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.

Hi you probably have something in the sump drain assembly (this is a common problem with Nautilus DW's) there's a screen on the right side of the spray arm with 2 screws remove them and take screen off use your fingers to probe the cavity be careful it could be glass.

If it does not correct the problem

!.You may have an electric pump . and it could be pump without water . so i would say a bad pump....but since you say everything is draining well...then I doubt the later...HOWEVER...you did say it ran forever...which is absolutely typical of something in the sump...drain area...which will make the drain cycle run because it believes something to be in the drain.....there is also a check valve...that the drain hose attaches to...(it comes right off of the motor assembly) when you take the hose off there is a check valve that screws into the hose or the motor assembly...(it could have debris in the hose that is not being drained all the way out and it is finding it's way back to the check valve) ...shop-vac the drain line...or the valve is screwed into the motor assembly where the hose disconnects...and there may be something stuck in the valve...unscrew it and check that the valve is in good shape...and free of debris......reassemble...and run through cycle....if you need any of these parts...or any specific instructions on replacement of these parts...here is a great site...Quality for less and quick delivery.

I hope this helps...I believe it will....Good luck and good day....thank you for your rating my effort....The Fang.

Starting the dishwashing cycle, extreme loud noise when dishwasher starts pumping water. Loud noise stays during pumping cycle. Dishes are clean and dry and no water in tub when cycle finishes.


If your unit is a Kenmore or Whirlpool (there are several other brands that use many of the same parts) and is less than 6 years old then it may pay to first check and clean out the chopper assembly for hard debris. If that doesn't do it then you may want to consider replacing the motor and circulation pump as a complete unit for between $160 and $200. Not too difficult a task for a moderately handy guy with some tools. Maybe 2 hrs. The bearing itself is not serviceable I understand, and would be considerably more difficult. Over six years old then you can buy a great quality machine for about $500.

A hard object has entered the wash module (on some models).
When the object is ground up, the sound should stop. If the
noise persists after a complete cycle, call for service.

I had the same problem. The motor had to be replaced. For as much as we paid for this it has not lived up to the Bosch name. It's never been as quiet as other people talk about, and then the motor went out! It's only 2 years old.
