Dirty water backs up into Kemore Dishwasher

rsmith0399 · 12-14-2011, 04:05 PM

We have a Kenmore dishwasher, model 665.16462300.

It washes dishes fine. And if we use it every day it works fine.

But if it sets a few days we find about 1/2" of water in the bottom that has a bad smell.

The dishwasher drain has a high loop under the sind and then empties into the garbage disposal. I have run the disposal with the water in the sink running full blast and it does not cause it to back up into the dishwasher.

I replaced the little flapper valve by the food grinder in the dishwasher but it did not make a difference. Is ther another check valve somewhere?

Thanks!
Ron

I don't think it is backing up I think it isn't draining properly to begin with. Somewhere there there should be a screen on the discharge to be cleaned I think. Not really sure. I've had that problem before and could always clear it by cleaning something somewhere.

It's empty after a wash cycle.

I don't see any screens or check valves in the parts list.

what do you call a high loop? How much higher than the disposal outlet is it?

6 to 8" higher than the disposal inlet.
About 2.5" from the top rim of the sink.

Yeah, sounds like it's coming from sink. does your sink drain slow or do you fill it to the top for some reason-either could cause this...usually on that d/w there's a check valve [rubber flapper] built into the hose that connects to the hose from the d/w drain port-see if that's ok....another possibilty is; it's fresh water [from a weeping inlet valve] and your d/w is loaded with crud [happens to the best of familys] so the two mix...to check that;turn water off for a few days and see what happens.
