GMC920X*127 General Electric Dishwasher - Instructions

I just plugged in the model number and a screen came up that showed all the part numbers that made up the model. picked out the parts that we needed and ordered it and within 2 day we had the new basket that we needed for our dish washer.
the service and ease was better that going to the appliance store and picking up the basket.
I was very happy the the service.

Unscrewed old one and installed the new one.

Looked up possible causes on your website. Website stated that more than 50% of time the cause was the piston and nut assembly. Removed the piston and nut assembly in bottom of unit behind screen on rear wall and saw that the gasket seal was completely gone . Ordered the part. took less than 10 minutes to install. Tested the unit and it drained completely. Thank you as i was looking at a more difficult repair if the pump had to be replaced.Repair cost less than $20.00.Before changing piston and nut assembly I cleaned the strainer and sump. disconnected drain hose and checked for blockage . i than checked your website that listed the piston assembly as the culprit more than 50% of the time. Thanks again

Turned off electical and water - took fillter screen out of inside, unscrewed cap took out valve and replaced it

Pulled unit out of cabinet took two top screws out of spinner spray arm and put back together.Old sprayer was plugged up not letting wash go through.Thanks for helping me fix and not replace unit.Saved at least 400.

As suggested. Pull washer, remove screws from top and replace with new part. Very simple and easy if you follow steps furnished by this site.

Removed old basket, put new one in. New basket fits but it is larger then the old one so it takes up more room leaving less room for dishes. My dishwasher is apartment size.

Service from PartsSelect was very prompt.

Removed screws on the drain pump filter screens at the back of the dishwasher, unscrewed the check valve, screwed in the replacement unit, and re-affixed the filter screens.

I lived with the drain problem for 6 months and reviewed on line trouble shooting which all pointed me to a pump or solenoid valve problem. I pulled the unit and disassembled everything before noticing that the rubber washer/stopper at the top of the check valve had erroded away and was not preventing water from pumping back into the cabinet when the drain pump kicked on. Always check the condition of this check valve first if you dishwasher is not draining properly. It was so easy once I found the bad part.

Without any specific directions with the part (which would had been nice. If it wasn't for my husband I wouldn't have known where to start.) I had to carfully pull the dishwasher out of the cabinet (it wasn't heavy) to unplug the power supply. Then we unscrewed 2 screws on the top and the upper arm connection came off. We replaced it with the new one, screwed it back on, reconnected the power supply and pushed the dishwasher back where it belonged. It worked out very well.
Also I want to say I am very happy with the length of time it took to get my part to me. (1 day) I was washing dishes it no time.

Thank You

Put on a new cap.

Took out old one and put in the new one. Not hard at all. Thanks

Open door, remove lower wash rack, remove 4 screws holding screen in rear of inside tub with 1/4 inch socket. Unscrew piston and nut assy for checkvalve, sounds like a mouthful but it is only 1 part. Checkvalve has 2 small ears on it which allow you to twist it out, it has treads on it. Flapper on check valve flapper rots away and water pumps back into tub instead of being routed to drain line to garbage disposal. Part with shipping was just over $20.

Removed the 4 screws holding the filter screen assembly in the back of the tub. This exposed the Piston and Nut assembly which unscrewed fairly easily.
Replaced with the new part, put the filter screen assembly back in place ran the machine. The machine still stops with the blocked arm message - just not as frequently. The web researched fix with the piston and nut assembly replacement was obviously not the final answer. I am now out of options I believe except to bite the bullet and get a new machine. Any other suggestions are welcomed.

After two repair people were unable to solve the problem, I read similar stories in your forum and decided to replace the check value as a last ditch effort. Looking at your diagrams it seemed like an easy repair. Removed four screws with nutdriver and replaced value by hand. Ran washer three times and water drained completely. Still puzzled that this wasn't the first thing a repair person would check.
Websight very helpful.

took out 4 screws pulled piston out and changed put back together. very easy and inexpensive!! thanks
