LG Dishwasher, Whistling, whirring sound

4 posts in this topic

LG Mod LDF6920.  Any time the pump is running there is an annoying whistleing sound.  It is quite loud ( can be heard from adjacent room ) sometimes and other times it is just barely audible.  I have seen from some brief web surfing that this is a common problem with various models being affected.  Lots of varying opinions as to what causes/fixes it so I am here to get some expert advise...  Can you help?

***********

 

During the WASH cycle---not the DRAIN MODE---correct?

 

All LDF6920 dishwashers have a flawed CHOPPER (also known as Macerator).

 

The CHOPPER has tips on it that are too much like an indian arrowhead tip---which causes noise during the Wash cycle.

 

A replacement CHOPPER corrects this.

 

Part Number---> 5832DD4001B

 

To replace the Chopper:

 

Remove both racks

 

Lift/remove the Lower Wash Arm (snaps out)

 

Remove the *Water Tower/Tube* that runs/routes from the Filter Housing---up the back of the dishwasher---and to the top of the dishwasher.

 

This done by removing the Phillips screw on the Filter Housing---which has a small stainless steel tab on it.

 

Then unsnap the mounting tabs (with your fingers or flat screwdriver) of the Water Tube at both---the top/center of the dishwasher and the back/center of the dishwasher.

 

Pull the Water Tower towards the front slightly---and twist/turn to the right---until it comes out of the Filter Housing.

 

Use a drill to remove all of the Filter Assy screws

 

Lift off the Filter Assy

 

At the rear of the Sump Assy---there will be a round/white Valve---pull it off (re-install the black o-ring if it has come off).

 

Remove the IMPELLER screw (reverse-thread) and pull.

 

Remove the Impeller Housing (lift off)

 

Remove the original CHOPPER and install the new one.

 

Re-assemble in reverse order (verify that the black gasket is correctly seated before carefully installing the Filter Housing).
