Flapper valve located in check valve body is distorted and warped. Diagram does not show this particular flapper valve. Only shows the one in the pump housing. Is this flapper valve necessary and if so where can one be found? Thanks

It is the same as the one you see on the diagram, order that one and you'll be fine.

I did, and it is slightly larger in diameter than the one in the check valve body.

What problem are you having with the D/W

[ptm526]

Does not completely drain after final rinse cycle. Probably not completely draining after other cycles either because dishes are not getting as clean as they should. Replaced the discharge pump and in doing so, discovered the small flapper valve in the check valve body distorted. It is approximately 1 1/16" in diameter and the other flapper valve in the pump discharge is approximately 1 1/8" in diameter and has a marking that says "out" on one side of the flapper. Checked all areas for clogs and pipes for kinks and found none. Is it possible to operate the washer without the small flapper valve?

You can run it without the check valve, but water will run back in from the drain hose. Did you check the piston and nut assembly?

[ptm526]

I assume you are talking about the piece that unscrews inside the tub with a spring and plunger. The bottom looks fine but there is a white rubber cone type washer at the top that looks pretty bad. Is that white piece at the top suppose to seal the hole at the top of the part? If so, it ain't doing it.

[abadfish66]

Bingo, there's your problem. That rubber piece needs to seal the hole, if there is any gap, it will not drain properly. During drain, water forces the plunger up and that rubber cone seals the hole, when it is not sealed water circulates back through the D/W instead of out the drain hose.

Thank you very much. Now if I can figure out what to do about that little flapper valve, it should be good to go. Wish I had checked that valve first but -----live and learn. Thanks again.

I'll see if I can find the part# for you.
