Squealing noise My Bosch SHU4326UC dishwasher has just started making a squealing noise during the normal cycle. Seems to happen at least 3 times throughout the cycle.

    It was squealing, not it won't turn on. I think the bearings are ceased.

    I have a similar problem ... unit squeals at various intervals however, the dishwasher is only a year old.  I would expect a longer life out of major mechanical parts such as motors, pumps, etc.

Had same squealing problem.... had machine checked over. NOTHING WRONG.
Repair people ran it a few times with just water and no squealing at all. they also ran it with detergent capsule [Fairy] No squealing. Have got it back to monitor it. Used Fairy capsules for a few washes and no problems. As soon as I used the Waitrose Essential concentrated dishwasher liquid, the squeak was back with a vengeance.
The moral of my story is TRY NOT USING LIQUID DISHWASHER DETERGENT

The pump motor is beginning to seize up. You may be able to take the dishwasher apart and lubricate the bearings and keep it going for a while, but at some point you will likely have to replace the pump motor assembly.

I confirm what Dot Milton found: switching from liquid detergent to powder fixed the problem for me.

    My dishwasher died after a year of the squealing!

    i think Selwyn Schultz is right suggesting the pump motor is seizing up.

Makes squealing noise


Good Morning Sherry, this is JK. I understand that your dishwasher makes a squealing noise. A screeching noise may simply mean that the pulley cables need to be soaped or greased. If this suggestions pans out and the problem still persists, think about what may have happened prior to this occurrence. For instance, did you notice any error codes, odors, or other strange functions prior to this issue? If you are still having these issues and can think of anything in particular, please feel free to reconnect. Hope this helps!

Squealing noise


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.

Usually this is the drying time of the cycle. I would have a professional look into the blower assembly and heating elements of the unit.

Bosch dishwasher buzzing at bottom


Hello

A vibrating noise indicates that your Bosch dishwasher is not level. Adjust the leveling legs until the dishwasher is level. Use a carpenter's level to assist you with this process. If the floor is uneven or unstable, fix the flooring. Or, place wood shims or a 3/4 inch piece of plywood under the dishwasher.


The motor has a plastic disc connected to it, which can break off if it wears out. You must replace the whole motor since this component is difficult to fix. Check the motor bearings, which can make noise if they get wet. If the bearings are wet, your tub seal is compromised. Pry it out with a crowbar, and install a new one. A squealing noise usually indicates that the heater fan is warped or rusted. Order a new one since you can't usually repair this part.

Kenmore 587-1519 dishwasher 5 years old just started making a squealing noise during certain times on any wash cycle. Noise is coming from under the tub.


Sounds like something is stuck in the pump. Your pump propeller may be going out causing strain on the windings of the pump. If you have anymore questions please comment me back.

Dish washer is seldom used , maybe twice a year. Notice during a drain cycle that the pump makes a squaling noise.This happens only after the load of the water has pass through the pump. The dishwasher is...


The pump impeller is probably plastic -- if so, dry rot is out.

Most likely the pump shaft is just dry from lack of use. More use will probably wet it enough to stop the squeal.
