40410148 General Electric Dishwasher - Instructions

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 corner baffles by lifting up and out. Cleaned the area and pushed new replacements in position.

Removed door seal by pulling on the end.
Press new seal in to the slot. Work in to slot a tree ound door.

Removed the white end of the top track. Pulled off the remnants of the rack roller. Slide the rack roller wheel into the track and popped the other end on the top rack (looked at the other rack rollers to see how it fit.) After that, I put the end back on the track.... Note what is the top and what is the bottom of the track end. Realizing that there is a wider area on the track to slide part of the white track end through to get it on without much effort.

I looked at your web sight and saw how to repair dishwasher.

Fiddled with the rollers until figuring out how to remove them. Hardest part was getting the stops off the ends of the roller guides. Replaced rollers, replaced rack, replaced ends of roller guides. Voila

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.

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.

I removed the 4 screws that hold the mesh drain cover in place . I used pliers to loosen the check valve piston and nut assembly at the rear of the appliance . I screwed in the new piece by hand . While I had the dish racks out , I put a new set of wheels and rollers on them .
I was 5 minutes away from buying a new dishwasher , but this website saved me HUNDREDS of dollars .
My dishwasher is as good as new now .

Removed screen bottom rear andfound a plunger type part, unscrewed plunger and found it was distressed around it and did not close of a tight seal. Placed new part into location and dishwasher now proforms perfect...

Removed stops on top rack. Removed rack, removed all rollers, replaced with the new ones. replace rack in machine replaced stops.

I just had to play around with it to attach the new cap without breaking it.....never did this before but eureka! it worked.

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!

took the front pieces off the front of each bar and placed the new rollers in place. Put the front cover peices back. ....that's it! The only thing i used the screwdriver for was to help remove the pieces, one was more difficult than the other.

First, end caps were removed from support rails to free the washer rack. This is a little tricky - flexible rear finger of cap is bent back, then rotated inboard to permit end cap to slide out. Ten top wash rack is rolled out of washer. Old roller support assembies are pried loose and then snapped off their clamp locations on the upper wash rack, one at a time. Then the new rollers are snapped on in same way, except no tools are required.
Two of the old rack rollers were clearly worn out from nearly 10 years of normal operation, where plastic shaft is a bearing surface.
