GSD4112Z02AA General Electric Dishwasher - Instructions

See GE web site for repair instructions. Take out screws at top of door. Slide unit out there is a spring on each side of the door just look at the good one for details. Easy fix. About 30 minutes.

i unscrewed old part and replaced with new one. Didn't know how to do it but figured it our quickly.

I removed the two screw at the top holding the dishwasher to the counter top; pulled on the unit - but found it stuck on something.
Of course the hot water feed and the drain hose were still connected and would not let the unit move out any further as there was no slack.
If I had thought about it - I would have disconnected these from under the adjacent sink. But I ended up lying on the floor trying to disconnect them from underneath the unit. It was a bit difficult as there was very little room to move the wrench and the screwdriver.
Once done, the unit came out very easily.
When tipped over I disconnected the old motor and replaced with the new. It was a very different design but fitted in very easily. The hanger took a bit of working out as the diagrams are not very clear.
The wires and clips went together easily. Once I had cleaned everything around the motor and the gunge that cames from years or washing dishes, it went back the way it came out. Albeit with the same difficulty with feed and drain hose.
We ran the unit with no dishes for a couple of times to clear our the muck left in the pipes when the system was down.
Now we have a fully functioning dishwasher again. Cost $250 for the pump and motor as opposed to the $800+ unit my wife was looking at!

Removed screws from back of door, a few more inside retaining the control panel (and a couple more from a small obstructing part located over a corner of the control panel). Then release/pull out the harness wires and tilt out the control from its retaining clips. Biggest problem was figuring out that the control panel was still being retained only by a stubborn clip that hung up in a slot on the control panel. Pliers were needed to pull out on the clip while tilting out the control panel. Replacement part then snapped in easily after its tabs on the bottom are inserted in the slots. Didn't have any trouble with the latch - - do not sure what the other entry means about being careful with the latch.

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.

Bulk of time was spent in diagnosis, eliminating other possible causes for the problem, such as wall switch and door switch and timer -- done with multi-meter.

Replacement of the control module was relatively easy, but **IMPORTANT TIP** Be sure to pull the specific model jumper wire from the old control module and re-attach it to the new replacement module. Otherwise, you'll just get a continuous blinking "clean" light and the dishwasher will not operate at all.

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.

took end caps off (one broke) slid in new disk rack and put caps back on.

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...

This was one of those wonderful repairs where anything went right.
The part arrived overnight as ordered and even though I was abit leary of it fitting, since it was described as a replacement/new design, it fit perfectly! As mentioned in another post here, draining the water out of the unit so I could tip it over to do the replacement was the hardest part!
I'm sure I saved over $100 doing it myself. Thanks PartSelect!

repair kit was complete and directions were easy to follow. my model of dishwasher disnt even require any of the adapters. really only required removing a couple of clamps and replacing everything as a single unit

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

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.

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 !!!

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