Hi.

There is no pressure valve that directly controls spray pressure, the only pressure switch in the dishwasher is used to detect the water level.

The groaning noise is usually given by a clogged or malfunctioning impeller pump.
The repair is done inspecting the hose connected to the pump, and then replacing the pump, which is usually responsible.

Before replacing the pump ensure that noise is not coming by spray arms rubbing on the baskets (that noise is not high pitched).

LG washer high pitch noise when water enters at beginning of cycle


Two possibilities: the water is coming in under pressure through a solenoid valve that is not fully open or the pressure pump is whining on its bearings.

Noise


Check if ADEQUATE water is present during the wash. (open the door and observe the level midway in the wash)

Also verify water is coming in for the rinse. Problem here only would likely be with the timer.

Check that the spray bar is free to rotate. Too high a load can keep bar from turning.

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.

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.

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.

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.

Dishwasher Making Loud High Pitched 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.
