Hi-

This is for an LG LDF6810WW. Similar to this one: http://136.166.4.200/contents/Dishwasher/LDS5811/LDS5811_Service_Manual.pdf

For the last week when the pump was running it sounded like there were little pieces of glass tumbling around in the water tray. Kinda like when there's loose change in the dryer, maybe not so loud.

Now the pump isn't draining the water. So far I;

- Vacuumed the water out of the drain hose. This confirms there's no blockage.
- Took the bottom cover off the pump "flywheel" (thing that moves the water) and checked for debris. Nothing there, and the flywheel (or whatever its proper name) turns fine.

Is it possible the noise I heard was a failing pump? Could that sound have been related to it? I probably need to move on to pump diagnostics, just wanted to check here first.

TIA,
Kevin

Ok, was searching around some more on this site and found this video; me thinks this is the same sound. http://fixitnow.com/wp/2010/09/02/appliance-war-story-whirlpool-kitchenaid-and-some-kenmores-dishwasher-not-draining-bad-drain-pump/

If it were my money, I'd blow through the drain hose with my own sweet lips before I bought a drain pump motor.

Ha ha. So using the vacuum to suck the water out *via the drain hose* doesn't confirm the hose isn't clogged?

Thanks....and btw been a lurker here for years, just joined today, love the forum/site.

Thank you My. Samurai. This site is very helpful! I did as you said and confirmed there was no blockage. Next, took off the drain pump and..........guess what, there was a piece of glass in there!@&$^@#

The impeller was chewed up a bit, but put it back together and in works now. The glass was about the size of an m&m, maybe a bit bigger.
