Helpful people,

I have taken the motor / pump assembly off of my Hotpoint HDA3400G00BB in an attempt to diagnose why the water does not drain out during the cycle.  Here's what I have diagnosed so far:
  • All other functions of the dishwasher seem to be functioning.  The dishes even come out clean, but the water does not drain out of the tub.
  • A trickle of water does come out of the tube connected to the garbage disposal under the sink during the drain sequence.
  • The solenoid that actuates the gate valve is working. It opens and closes the gate at the appropriate times.
  • From looking at the gate valve, it looks like it does not seal the path that leads water to the tub.
Here's a video that shows what I'm seeing:



If you have problems seeing the video in the post, here's a link: CLICK HERE

I have two questions:
  1. Does my gate valve look broken or normal?
  2. What would be the appropriate part number to fix the broken part?  I looked at the schematic for the motor / pump assembly on GE's website, but it appears they don't have a part # for the valve. CLICK HERE to see the schematic.
Thanks in advance,

Nate Oleson

Hello, my undrained friend. You would be well-advised to make a visual assessment of the drain check valve. Our turgid host has prepared a page on this especially for you. Come with me and let's have a look together:

Here is the part link for the check valve:

If the outer rim of the plunger gasket appears to be worn off and not large enough in diameter to make a correct seal, then you can be certain that you have found the problem.

Moostafa,

While I was waiting for someone to reply, I kept searching for more solutions and I stumbled upon directions that encouraged me to look at the drain check valve (aka "Piston and Nut assembly")..

You are spot on with your diagnosis however.  The seal had somehow been worn away to almost nothing. Replacing the assembly has fixed the problem.

Thank you for your help.
