Question about LG LDF6810ST Stainless Steel Built-in Dishwasher
Our LG dishwasher started making a very high pitched whistle about 6 months after we got it. The noise seems to be coming from the bottom of the dishwasher. I have pulled out the arms and cleaned them thoroughly (there was nothing in them) and have inspected the seals and they look good. Any ideas?
Top rack must be pushed firmly in so rotating sprayer is mated to the back and sealed otherwise water during rinse cycle will leak causing a high pitched whistle. Also check to make sure there is no food debris between seals. This solved my problem.

First a suggestion...try this guys solution with the impeller blade or ordering a different part. http://forum.appliancepartspros.com/dishwasher-repair/318842-high-pitched-squel.html
Now the rant...NEVER BUYING AN LG ANYTHING AGAIN!!!! Just talked to LG customer service they are worthless. I have the LDS5811 with the same problem. If you aren't going to man up and back your product when there are major flaws I don't want to buy from you. I have spent 250 bucks servicing this unit and it is only 4 years old RIDICULOUS. LG you better get your act together. I am not going to buy another LG appliance unless they start owning up to their faulty manufacturing. This dishwasher was not cheap when I bought it and has been nothing but a head ache. First the wiring harness got loose and shorted the board, because they embedded the wiring in the insulation in the door. Now this stupid noise that tortures any animal within a mile. My home warranty won't fix it "till it breaks." Back into ear purgatory my family goes till I can get this part.

The spindle on the motor passes through a rubber seal. This seal just needs a bit of grease (I used white lithium grease). See video here for motor removal on older models (with chopper blade). You will see the rubber seal the motor spindle passes through. The impeller mounts on this spindle. Newer models with the filter inside the bottom of the dishwasher are a bit more difficult and I can't find any videos. However, the problem is the same - lack of grease on the seal. I have done this with two models (one with chopper blade and one with filter) and problem was solved).
