14 posts in this topic

Check valves have been replaced, no clogs but dishwasher continues to drain through wash cycle and because of lack of water, does not clean dishes. Ideas?

The check valve in the drain pump is bad and needs replacing.

Believe he said he already replace the check flap...this is to keep water from back flowing from the drain, not to the drain.

what is the situation with the drain hose? Does it leave the drain pump and then go thru the floor and connect in the basement/crawlspa@e?

if so, this is the problem. Tub is siphoning out.

Two check valves were replace and I believe it is attached under the kitchen sink pipe to drain (that was where appliance repair man was looking). He said he has never seen this before nor had 3 others he called.

Needs to be attached above the S-trap (upstream,sinkside) so that air can enter hose once drain is complete, otherwise water will continue to siphon out

GE specialist is here. It is definitely attached well above S-trap. Continues to drain and to such a degree that the middle and top arms aren't spinning. He is perplexed and said " This is a weird one."

Update: Even when drain pump is shut off, it continues to drain. Any suggestions out there for something else to look for?

Yup - definitely siphoning, Drain hose needs to be raised in a loop and the connected into the drain as mentioned so that it can "breathe"

It has the loop. Currently checking to see if washer arms might be clogged- suggested by GE tech support.

Fill the unit with water and get it washing, then initiate a drain cycle - while it's draining open the door and watch it - if the water continues to drain out on it's own, you have a siphoning drain issue

Thanks for all the suggestions and sticking with this especially Kdog. Ends up the problem is clogged spray arms (top and middle) and clogged mesh screen at the bottom. Poked holes in the mesh screen (which will be replaced) and got the top spray arm unclogged and the draining stopped. Will replace the mesh screen and middle spray arm. Too much water coming in without anyplace to go caused it to drain. GE tech support said it was rare but it does happen. Might it be because we are on well water?

I hope this thread helps someone else someday.
