Dishwasher would not drain

Took off the back screen, 4screws. Unscrewed old piston assembly. Put in new piston assembly, put screen back on. That was all there was to it. Now it drains just fine. I also added 2wheels to the front lower tray.

Wash cycle leaving water in the dishwasher

Looked online for a general cause. ABout 60 to 80 percent, the cause was the piston and nut assembly located in the back of the dishwasher. Ordered the part and installed in nothing flat. Only four nut screws to remove the take the filter off and unscrew the piston and nut assembly. Next cycle, no water and the drying cycle seemed to be better. Guess because no water in the bottom of the dishwasher. Good input and fast turn around on the part.

Dishwasher leaving dishes dirty.

Removed the 4 1/4" screws holding the rear screen to the bottom of the inside of dishwasher. "Piston & Nut" assembly was badly corroded- to the point that no dirty water was leaving the dishwasher. Because the appliance is at least 10 yrs old and there was nothing happening during the rinse cycle, I initially assumed the worst- that the pump was bad. After reading the other descriptions of the problem here, I said, "what the hell?, if a $20 part fixes it, I'll be amazed- if not, I'm out $20 and looking at another $300 for a new dishwasher!" The $20 part (inc. shipping) did the trick. Thank you, and your website is on my "highly recommended" list! One note- the piston & nut assembly did offer some resistance as you might expect after being "gunked" in place for 10 years. However, the top has some lugs or ears built into it, so a few taps with a hammer on my largest straight-blade screwdriver loosened it right up...

Dishwasher not draining at end of cycle.

I put on my rubber gloves, removed the lower wash rack, removed four screws from the drain guard. I unscrewed the defective part, installed the new assembly and hand tightened. Replaced the cover and installed the screws removed earlier. Re installed the lower tray, and ran the rinse and drain cycle. It has been working beautifully ever since.

Significant amount of water at bottom of dishwasher

After running a test cycle and realizing the pump was working but not pumping all the water out, I checked the troubleshooting guide and parts list.
I found there was a check valve at the back of the machine and when I removed it I saw it was split causing the water to return into the unit. I ordered and replaced the check valve and the unit is back in perfect operation.

CustomerJoseph from Spartanburg SC

Dishwasher had would not drain completely at the end of a washing cycle

First I removed the four screws from the screen/cover located at the back of the dishwasher. You will notice a mesh screen in the center of this cover. The check valve is under this cover midway between the sides. The check valve is unscrewed counter clockwise. I had to use a pair of pliers to start turning the valve. There are two "ears" on the top of the valve. You will see a rubber cone shaped piece that should completely cover the opening when the plunger is depressed. In my case the rubber was almost completely gone allowing water in the drain hose to return to the dishwasher after the drain pump stopped. The new check valve threads back into the opening and should be finger tightened. Replace the cover/screen and you should be good to go.

Dishwasher would not fully drain

After researching for a few minutes on this site I was pretty confident that the problem I was having was a faulty check valve. I removed the 4 screws holding the cover in place at the back of the dishwasher tub, twisted out the check valve and saw it was obviously shot. I ordered the correct part and 2 days later I had the dishwasher working like new. Installation was a simple as could be....twist in the new valve and reinstall the 4 screws.
