SOURCE: Dishwasher Making Loud High Pitched Noise.

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.

SOURCE: Dishwasher Making Loud High Pitched Noise.

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.

SOURCE: kenmore elite dishwasher making loud buzzing sound when washing

I had the same problem with by Kemore Ultrawash after two years. The motor bearing went bad because the seal went out and dish water got to the bearing. If you are handy, this motor comes out after taking the dishwasher out. I was surprised how easily the motor came apart from the dishwasher, a good design. The motor has three screws that holds it together, I took them out and took the motor apart.
I took the old beaing off the shaft with a grinder, careful not to groove the motor shaft. I did, but just put some high temp silicone caulk in the groove before I put the new bearing on the shaft. I bought a new bearing on the internet, it is a 22mm x 8mm x 7mm. I bought one that went in a small engine, a quality one. I placed it on the shaft, put the motor back together and put the dishwasher back together. It has run quiet and great for many weeks now. I expect the dishwasher may last many years now, because the bearing I took out was a cheap aftermarket one, and the new one is vastly superior in quality.

Good luck and fire away with any questions. I love this dishwasher and am glad I could fix it for 19$ and some of my time.

SOURCE: Whirlpool Gold Dishwasher makes a very loud noise when running

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.

SOURCE: dishwasher is 1.5 years old and makes loud noise

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.

If it ismaking a steady noise, the motor that runs the defrost timer may be making noise. I f the timer motor is making a loud noise, then you should replace the timer.Vibration noises are often caused by dishes or containers vibrate on a shelf inside.

Frigidaire dishwasher model GLD2445RFCO is making noise


I have the same problem with my dishwasher. If you remove the kick plate while it is running, There is an electric motor underneath. If you push up and pull forward on the electric motor, the noise will stop. I used a block to prop it up and the noise stopped. You may want to try it.

Making loud noises when washing, nothing is obstructing the top and bottom wash arms and the dishes are clean when the cycle is over.


Is there a chance the dishes are moving when the machine is on? Cound the water jets(spraying the door and sides) be the cause of the noise. Is the sound insulating blanket on the outside of the machine? Try running empty on a shor cycle to help diagnose the problem.

Doesnt clean dishes, seems to be no water coming into machine


There should be about 2 inches of water in the bottom of the DW.  If it is filling but not washing the pump may be bad.  That might explain the loud noise (motor bearing).  I assume that the detergent cover is opening but no water is being sprayed to dissolve it.
