I believe this is caused by sediment in the water line. Clean it out or you can possibly solve this by running a delimer through your system. If this has been occurring a real long time, you may have to replace the water line itself.

Whistling sound


Kind of hard to tell without hearing it. Also when does it occur? During the fill portion of the cycle? During the main wash period? Or during the drain portion of the cycle? Also how old is this dishwasher?
If I had to guess (and I do, since I don't have the answers to the above questions), I would think that the bearings of the main wash motor were going bad; especially if the dishwasher is more than 7 or 8 years of age.

Why does my Kenmore QuietGuard Dishwasher Whistle?


Is it during the wash cycle? That is air getting past the drain flapper. If you install a trap in the drain line it should go away.

Our LG LDF7920st dishwasher (6 months old)makes a whistling noise


Hey, consider the float assembly!

We bought this dishwasher and ran it for the last 1 1/2 months and it made a grinding and whistling sound from day one (it's supposed to be nearly silent in its operation). Turns out the drain pump was cutting in while the machine was still filling, thereby emptying the wash tub of any water. Then, when the cycle proceeded to wash, the dumb thing had no water and made a horrible noise. So I had to pitch in at least 2-3 litres of hot water, and then it worked quietly! Had to do this every time there was new water intake.

After working with the repairmen - four visits later, we isolated the float assembly as the problem and they set about replacing the part. Turns out the two parts were markedly different. LG HAD INSTALLED an older model float assembly at the factory and it was the problem. The replacement part was the correct float assembly and things worked perfectly after that - thank goodness. No more babysitting the dishwasher.

Don't let anyone tell you the motor assembly needs replacement. I have seen that cop-out 'fix' all over the web. But use deductive reasoning to find out where the problem is in the cycle, and explore this option first - it's a quicker and cheaper fix than replacing the whole motor assembly.

'Mr. Float' as he is now called works like this:
-expels any residual water in the tub from the last wash
-intakes water for the wash or rinse
-whirs 2-3 times prepping for the cycle
-begins to wash, quietly
-expels at the end of the wash or rinse.

He used to:
-expel residual water
-intake new water for wash or rinse
---drain pump would cut in WHILE still filling
-machine would whir once, realize it didn't have enough water
-perform a brief top-up intake shot
-begin to wash and whistle and GRIND (this is where I would have to add the water)
-expels water from wash or rinse, and start all over again.

It's a good dishwasher and it will work, but the right model parts have to be in place!

Dishwasher doesn't drain


Greg, if the model number ends in GO1, your dishwasher has a piston nut assy. thats problably giving you the grief. If this assy. goes bad you will have water left in the tub at the end of the wash. A common GE problem. It's located under the filter screen in the back and just unscrews out. Part number is wd24x199. It's an easy fix. Look up the part on the net to get an idea of what it looks like. Catriver..post back.
