GMB939JC119 General Electric Dishwasher - Instructions

The replacement of the motor and pump assembly went smoothly and without difficulty however this did not fix the problem. It then appeared that the inlet water valve was not operating properly, so this part was ordered and instlled, a very simple proceedure that could be done witrhout removving fthe dishwasher from its cabinet. -- Again failure to run -- the timer assembly and electronic panel were then removed and examined. The control panel had no visible defects, so the timer assemblyand its cover was removed and examined . Uing a variable power supply the drive motor for the timer was energized and tested. As the motor ran properly the electrical switching contacts were then carfully checked, it was discovered that one contact set was heavily pitted and burned. These contacts were carefully cleaned and pollished with 1000 grit sanding paper. The actuator leaves were examined and two sets were found to be slightly out of alignment. The leaves on these sets were bent slightly to insure they were in line with the rest of the leaf serts. It was then noted that the rotating leaf('s) actuator had a home position indicated by a molded depression at one location and the motor was energized using approximately 5 volts ( a nine volt battery could also be used as a poer supply) observing prolper polarity to run the rotator until the home position was established and the actuator rods paul dropped into this depression. The assembly was then replaced in the diswasher using care to make sure that the actuation arm and spring were positioned properly weith the arrow end of the arm located in the recesss of of the rotating timer disk use care in placing the assembly and do not lose the sping which attaches to a mounting post and the arm. You may want to take a picture of the spring and arm locations when you rwmove the timer assembly to properly re-assemble all components, the repaired unit was placed back in its cabinet and a full cycle run to establish proper operation. And unit checked ok! Some of these proceedures are not for the weak of heart. I am a retired engineer who has been repairing my own equipment since graduation. .

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!

after I let the unit rest on its side to expose the bottom part, I took a picture just in case for reference; I marked all electrical connections, so it would go to right place into the new unit; removed the old pump unit by loosening the rubber clamps, for the inlet and outlet; detached the support sling for the motor unit; installed the new pump unit; it fits like a charm and it was wonderful; I had some bad experiences of replacement parts from other suppliers, on many things that I fix , that won't really fit like the original, but this one fits like a charm; I made my first test run with just water with out the detergent and after one cycle I used the necessary dishwasher detergent and it works just like brand new; Thank you, PartSelect, I will be ordering any of my part needs from you. - G.V.

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!

Remove wooden top and pulled out hose from spray arm. Removed spray arm. Installed top hose fitting using a bit of silicone grease for ease of installation. Reinstall spray arm. Stuff hose in same position as old hose. Lay dishwasher on it's back and remove old hose from pump by removing clamp. Replace new hose in same position and reclamp. Stand dishwasher back up and reinstall top. Wife is now happy! I could do this again in half of the time.

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

Removed filter/screen by unscrewing 2 screws with a nut driver and then unscrewed the old Piston and Nut assembly and simply screwed in the new part. Problem solved and my dishes are much cleaner and the water is draining out completely. Easy fix for this frustrating problem.

Opened the box the new silverware basket came in and replaced the broken one.m

Removed filter screen with the socket set, removed the piston and nut assembly with pliers, and installed the new piston and nut assembly. Put filter screen back in with hex head screws. During the process, I opened the float regulator and cleaned it out too. Water backup problems solved.

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.

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.

Basically, I told my girlfriend, hey, if you are board, this box has the parts to fix the dishwasher in it. When I got home from work, I had to connect one wire, and tighten a couple of screws. The kit has great, easy to follow directions. Thanks!!

Not really difficult to do. First remove the washer from the counter and flip it over. Carefully determine the correct drawing in the instructions which matches your machine. Follow insructions and double check everything. Took about an hour - and I saved about $350.00 by fixing it myself rather than buying a new one!

Unscrewed unit from counter and loosened legs using adjustable supports under dishwasher. After switching off water under sink and power at circuit breaker, removed motor and pump assembly and replaced with repair kit.

Turn water off and unplug unit first. I remove the 2 retaining screws under counter, pulled out dishwasher. I laid it on it's side to get to pump, loosen up Hose clamps on inlet and outlet ports on pump. You may need a towel or rags to soak up a small amount of water from hoses and old pump. Removed the two hoses on the side, note the lowest one is the drain hose. Un plug all wire connections and loosen support bracket. Removed old pump and installed new one in reverse order. I had to use the 90* adapter hose and the white adapter for my drain hose.The kit contains all adapters and it all fits perfect. Reinstalled and tested unit worked great!!!
