GE Profile Dishwasher, Model Number gsd5940d00ss, does not drain completely

Question: My GE Profile Dishwasher, Model Number gsd5940d00ss, has 2 inches of water left in the bottom of the dishwasher at the end of the dishwasher cycle. What is causing this?

Answer: If the drain line isn’t clogged or kinked the Piston & Nut Assembly is most likely the dishwasher part causing your problem. The piston and nut assembly is for a check valve. It is used on General Electric, Hotpoint, and other brands.

To check it, remove the screen/filter in the back of the tub. Once done you will see the Piston & Nut Assembly. Remove it by simply unscrewing it.  This part has a plunger on a spring. When you press up on the plunger it should completely stop up the hole in the top of the part. Sometimes the rubber top part of the Piston & Nut deteriorates and the part needs to be replaced.

Other causes of water not draining from your dishwasher can be:

  • Restriction in the pump
  • Leak or kink in the drain hose or a loose connection in the drain hose under the sink

  1. Our Whirlpool dishwasher bought from LOWES is new and will not drain. We installed a new disposal and removed the both plugs / stopper. We also checked for kinks in the drain hose. This should’ve quickly solved the problem but didn’t. We had the same problem with the last dishwasher before giving up and buying this new one. HELP!!!! Thanks Mark from Detroit.

  2. You are correct these changes should have solved the problem. Have you checked that the dishwasher is level? You may need a service technician to take a look at this.
