Standing water in dishwasher after final rinse cycle

Disconnect the dishwasher power supply and water connector.Then disconnect the drain hose.Take off the hose from the pump and on the plastic valve is the black valve flapper.Mine was swollen twice the size of the new one.Replace with the new one.You have to pull the dishwasher out and turn it over to do this.
The check valve was totally worn out.You must turn the dishwasher back to it's in use position and open up the door.Inside the lower rear wall is a plastic cover with 4 screws remove these and the cover.Then unscrew the piston and nut assembly and remove the check valve.Simply replace with the new parts and reinstall the cover.
I replaced the gasket before I reinstalled the check valve even though it looked ok.To do this you need to turn the dishwasher over again and remove the 4 screws dolding the resevoir the check vave is in.Replace the old gasket with the new one and reinstall the new gasket.Do this after removing the old check valve and before intalling the new one.
On the bottom inside the dishwasher I noticed the large white gasket on the floor was falling apart so I replaced that also.I'm glad I did because below this assembly there is a reusable plastic filter that was totally plugged that I cleaned and reinstalled before relacing the filter gasket assembly.To do this you must remove the plastic water jet.With a screw driver there are 2 plastic tabs that must be carefully pulled out so you can pull out the water jet.Remove the 2 screws and plastic cover on top off the gasket assembly.Retain the 2 screws but you will not need the cover it is part of the new gasket assembly.There are two clips you need to carefully pry off.Then lift out the old gasket assembly and replace with the new one.Reinstall the 2 screws that held the old cover before and If reinstall the old clips if not damaged.You can purchase new ones but usually not needed.Then gently snap the water jet in place.
Put the dishwasher back under the counter and reconnect the power,water line and drain hose.

Dishwasher would not drain.

I removed the four screws of the filter frame exposing the check valve (piston and nut assembly) . I unscrewed the old check valve and replaced it with the new one.

Dishes were coming out with nasty film and chunks - gross!

Read about somebody else with the same problem and ordered the check valve. 4 screws off, twist out old valve, twist in new valve, 4 screws back in. Now dishes are see-yourself clean.

Dishwasher not draining

Found great information on this site describing the problem. My 9 year old GE Triton dishwasher has not been draining. I thought at first it was something stuck in float somewhere or perhaps a bad pump, but after searching around, I found this site and other stories similar to mine. Most of the reports suggested a worn check valve in the floor of the dishwasher tub, apparently a common issue with some GE models. I removed the strainer located at the back of the tub (4 screws removed w/ 1/4" nutdriver), then unscrewed the check valve to inspect it. Saw that the valve seat was very worn. Ordered the replacement part, received it 4 days later and installed in less than 10 minutes. The best part was I didn't have to remove the dishwasher or crawl underneath to complete the repair. Well worth the $20 for parts & shipping.

CustomerThomas from Tallahassee, FL

Dishwasher was retaining water after completed wash cycle.

Changed check valve and valve flapper. Had to pull dishwasher out of cabinet to get to the backside. Removed check valve and replaced valve from inside dishwasher ( all the way at the back, large nut holds in)but had to remove lower assembly from rear in order to change out the gasket. Removed large black flexible tube and replaced flapper valve. Just be carefull sliding hose back over section containing flapper valve. Fairly easy switch out. Took care of problem.
