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: Noisy dishwasher

SOME DETERGENT DISPENSERS ARE ACTIVATED BY A SOLENOID THAT IS ELECTRICALLY CHARGED. IT WOULD BE POSSIBLE THAT IS WHERE THE NOISE IS COMING FROM. IF YOU WANTED TO CHECK, REMOVE THE DOOR PANEL AND SEE IF THERE IS A ROUND ITEM AT THE DISPENSER ASSEMBLY WITH TWO WIRES ATTACHED TO IT. PUT THE DISHWASHER INTO A CYCLE AND WHEN THE NOISE APPEARS, GENTLY PRESS ON THE SOLENOID TO SEE IF THAT IS WHERE THE NOISE IS COMING FROM. REPLACE THE SOLENOID TO SOLVE THE ISSUE.

BE SURE ALL RETAINING SCREWS ARE TIGHT.

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: LG dishwasher is whistling a high pitch tune

It is difficult to be specific without knowing the model number of your LG dishwasher.

On newer LG models, the most common cause of noises is from debris stuck in the lower filter assembly area. Recommend you remove the lower spray arm and the screws that holds the filter sub-assembly in. After removing the assembly, inspect with a flashlight to search for any debris that is jammed in that area. Also rinse out the filter as best possible to remove any thing you see in there. Reassemble and test.

High pitched sound during spin cycle


That machine doesn't have a belt. It is more likely that you have a bearing going bad. You may also have a tub seal starting to go which then leaks water onto the bearing, damaging it.

LG makes a high pitched sound during water add cycle


Hello.
The high pitched sound is a definite sign that the water valve in use is failing. The squeal is from a restricted water flow through the valve because it is not opening all the way. You will need to choose cold or hot to narrow down which valve is bad and replace that one.

High pitched buzz/whine during wash cycle only, spin fine


1) Make sure valve is open all the way 2) some machines have a screen inside of the hose hook up which could be clogged. 3) last check to see if it is the hot or cold by switch your selector switch on your machine to hot then cold. If one of these positions eliminate the noise then the valve in the machine is bad.

Kenmore washer Model #16852 make high pitch sound while spinning.


Is the high pitched sound that you hear during the spin cycle or just all the time during the wash? If it's during the spin cycle it's probably your transmission and the only way to fix it is to replace the transmission. It's only going to get worse with time and soon enough it will just seize up on you and nothing will work. A transmission for a Kenmore runs anywhere between 150 to 250 dollars. 150 if you can find a refurbished one. You can find them at any appliance repair shop. Kenmore transmissions are fairly common as it's a big name. I hope this helps you and if you have any other questions or need help with installing it let me know. I can give you an easy step by step walk through on how to install it. It doesn't take too long. Good luck to you.
