GSC3400Z01BL General Electric Dishwasher - Instructions

Simply opened the dishwasher door, removed the gasket insert located in the middle inside of the door and replaced with new. Also went ahead and replaced the seal on the inner edge of the inside dishwasher door. Found very simple instructions on Google on how to do make this repair. Very easy!

Ordered motor and pump and replaced. Motor pump kit also comes with a drain solinoid so if that was the problem the kit repaired it. One issue is the size of the hanger to ensure the pump does not just hang on its mount. The directions were not very clear and after some trial and error I got it to work to.

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

Remove shield in rear. Unscrew valve using hand. Screw new valve in place.

Remove the back filter to access check valve assembly. Twist check valve assembly to remove, not significant deterioration of rubber cap. Install new assembly. Re-install filter. Super-easy and effective!

remove the screen at the back bottom of dishwaser. (4 screws). Unthread piston and and nut assembly for check valve....thread in new one.
Problem solved....no more water $10 part....no repair person !!!

Followed the simple instructions to unscrew the old unit and replace with the new one. The unit was easily located on a diagram on the internet and the website instructions for removal were spot on.

Used Phillips screwdriver to undo brackets that keep dishwasher in place. Pulled out dishwasher from underneath the counter. Placed hinge arm in spring, hooked spring onto clip, placed hinge arm in clip. Put back dishwasher under the counter and screwed in place. Took all of 15 minutes. Saved 185.00 for service call.

I Just Open Door And Put Fill Cap In And Turn That It

removed screen at back of dishwasher from the inside. Twisted piston & nut assembly out by hand and replaced with new one. Very, very simple. Dishwasher works perfectly now.

A no brainer, replaced old fill cap with new fill cap. Delighted I was able to order the part, website is user friendly.

Unscrewed bottom of spray arm support assembly counterclockwise by hand for removal. Inserted new part and screwed it in clockwise by hand for installation. Worked perfectly. Video was helpful.
