GMB930JB119 General Electric Dishwasher - Instructions

First I opened the package and screwed the new dispenser cap into place.

Just put the part on.

Turn off power at breaker box.
Remove lower covers and 2 screws into counter top.
Verify sufficient length on water and electrical connection to allow sliding dishwasher out approx. 2/3. I disconnected the electrical at the j box on the dishwasher. If you must disconnect the water line, shut off supply, usually located under nearby sink, and provide a rag or sponge for small amounts of water left in supply line.
Carefully pull back the insulation to expose two screws on top where water line runs into the center.
Pull the top tray part way out and reach in to hold the spray arm while removing the screws. The spray arm will easily drop out.
Hold the new spray arm in place making sure the raised screw posts push into the holes, then reinstall the two screws. Done. Pull insulation back into place, retape if necessary. Reconnect electrical and water if necessary.
Slide unit back in, checking alinement. Rescrew to counter top and reinstall lower covers. Task complete. 15 mins if prepared. 30 mins if both elect. & water are disconnected and you are somewhat hesitant.

Went to repair parts on troubleshooting and found check valve assembly to be most common problem. Went to parts diagram to locate assembly and found it somewhat confusing as to exact location. Ordered part(s) on percentage as the problem. Received part next day (great)! Pulled dishwasher out and found I did NOT need to do so to replace check valve which is replaced without having to remove dishwasher. The gasket replacement was not necessary as it seals sump area from bottom of dishwasher and not the valve as it appears on the parts diagram. It took about 2 minutes to replace valve itself and it was the cause of the problem.

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.

Simply screwed in new cap

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

Put on a new cap.

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.

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.

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 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.

Shut off water, disconnect power,remove
Faulty valve,install replacement part.
