GDU4KV-CN Maytag Dishwasher - Instructions

removed the door gasket by just pulling it out and pushing the new one in its place. very easy, took five minutes at most. Then removed the 7 screws holding the inside of the door in place, removed the dispenser assembly, held by two drive screws and replaced the dispenser door latch grommet. Finally, removed the insulation foam gasket. Had to scrape the old adhesive from the door as the old a\gasket had disintegrated. This took the most time. Then just pressed the new foam gasket in place. Reading the comments from others was a big help. Don't think I would have replaced the dispenser grommet had I not been warned about it. I'm sure it was part of the problem. All is well now, no leaks.

Took off old part. Modified new roller w'knife. Found a nut and bolt in scrap pile. Attached.

This ended up to be a (2) phase project. The first repair was to replace the door seal and inner door foam. Thanks to earlier online comments this part was really easy, but we still had a small leak. When I had removed the interior face of the door panel to replace the inner door foam, I had noticed the insulation was wet and deducted that the 'soap cup door latch gasket' was the real culprit so I had to place a second order (Phase 2). The order came quickly and in time for next Saturdays to to list. My advice is to replace all 4 items at the same time and save on mailing cost and repair time; reservoir O-ring, soap cup door latch gasket, inner foam gasket and door gasket. net repair time, about an hour start to finish.

The initial repair was more involved due to figuring out how to get at the problem. A foam sealer strip located at the bottom of the inner door had lost it's seal. I first sent off for one and it was of relatively thin material. It was carefully installed but still leaked. I ordered another one from Part Select and it had thicker foam. It was installed right over the previously installed strip and made a tight seal. (knock on wood)

I first removed 7 Torx screws holding the plastic housing to the door. Then removed two hex screws holding the
dispenser in place. At first I thought that the wax motor was broken, but measuring it with an ohm meter, it had the same resistance as a new wax motor (about 2-3 kOhms). Examining the release mechanism it looked like the stem at the back of the latch was a bit bent. I replaced both the latch and the slider. However, I probably only needed to replace the slider. After reassembling the pieces, the soap dispenser now works. By the way, as another poster noted, you can only test the mechanism when the dispenser door is closed and the latch is
displaced from its normal position.

The wax motor seemed to work.
At first I thought something was broken and I tried to figure out the "theory of operation" Working the actuator of the wax motor, I COULD NOT GE THE LATCH TO MOVE THE WAY I THOUGHT IT SHOULD. I ASSUMED EITHER IT WAS BROKEN IN SOME WAY I COULD NOT DETECT OR THERE WAS A FLAW IN ITS DESIGN!

It took a long time to figure out the latch would not be worked open unless it was actually holding the lid- this positions the latch at "half mast" and allows the mechanism to "pick it up from there" and open the rest of the way. So once I figured that out, I concluded the failure was really just worn out parts that were out of tolerance for how this "half mast" position and opening was supposed to work. So I ordered all fresh pieces just to be sure, assembled it (very easy) and put it in (easy). It all works fine now.

First I called a repairman. He saw it was a certain model Maytag and would not fix it. It washed, but would not drain, so rather than buy another I took about an hour to carefully remove the washer and the motor / bowl unit from the body. Then it was easy to see what was wrong. The problem was a broken lifter arm in the bottom of the bowl. This caused the drain solenoid piston to "travel" too far and actually dislodge from the solenoid during use. You have to remove the lower spray arm, drain grate and then the lifter is a little black plastic "arm" on a metal rod that is actuated by the solenoid under the washer. The lifter fits over the rod and is held with a snap ring. Re-assembly was easy.

Whoever manufactures this part, hope they read this and strenthen this part. The very thin legs break very easily.

I removed the threaded broken-off part from the extension thing. The spay arm came off, since nothing was holding it on any more. I pried the cover off below that - 4 tangs.
Then I used needle nose pliers to unto the strange pointed nut that holds the spray arm support in place. Then removed the borken support, replaced with the new and reassembled in the reverse order of disassembly. Really pretty easy.

float was missing palnut and letting the float slide up too much causing small leak around the float

After performing some maintenance to get the water flowing properly through the system (that's another story) the door was leaking very badly during any test run of the dishwasher.

We thought it was the gasket because the old one was calcified and dried out from years of harder water.

We ordered the new one and in minutes after receiving the new gasket we had a firm seal and our dishwasher was back in action.

I simply ordered new rack assembly for the upper and lower rack units. Removed the old racks and slid in the new ones. I gotta say, Part Select saved me $50 for these racks compared to everywhere else I looked and called.

Thank you Part Select !!!

The real cause of the leak had nothing to do with the foam strip. The latch for the front loading door at the top needed to be adjusted to hold the door in tighter to the rubber door seal. This simple adjustment stopped the leak but since the foam seal was all encrusted with dried detergent from probably years of absorbing the leak, I replaced it with your new foam strip. I used a screw driver with torx bit and removed the stainless screws holding the inner door to the outer door. Once these were separated I removed the old foam strip using a putty knife and lacquer thinner. Placing the new strip onto these cleaned surfaces was the easiest part of the whole repair.

The dishwasher is well engineered to perform this work.

Remove the bottom two panels to provide access and visibility to base of pump motor.

Locate plastic pump locking lever and push toward rear of DW to unlock pump from DW.

Inside the DW remove basketsand spray arms. Revove screws holding cover over pump motor and remove cover.

From below raise pump motor and support with block (piece of 2x4 worked well).

insde DW, removre old gasket, clean well around pump and botom of DW, install new gasket.

From below remove block to drop pump motro back into place, and re-tighten locking lever by pull toward you.

re-assemble inside componets, run through a rinse cycle to test for leaks and replace bottom panels.

First, the problem was the little rubber gromet on the soap door operator lever. It was not the door gasket. I had to use a torx driver to remove the 6 screws that hold inside door panel on. After separating the inside door panel from the metal door I was able to see the soap door operating mech. I then removed 2 hex head screws from the soap door operator. I was then able to remove the operators plastic lever along with the rubber gasket. I then slid the new rubber gromet over the operator lever and put the mech. back in place. I put a little silcone grease on the plastic slide bar that operates the plastic release lever of the soap door. I then made sure everything worked properly. I then put the inside door panel back on.
No more inside door leakes when the dishwasher is running.

Thanks to repair stories about door leaks on partselect.com I ordered parts for the detergent/rinse dispenser in addition to the door gasket. The installation of the door gasket is really easy, simply remove the old gasket starting at one end. I needed a small screwdriver to get the old gasket end out of its channel, then pulled the entire gasket out. I cleaned the channel with water and simply pushed the new one into the channel, starting at the left bottom and continuing around. It is important not to stretch the gasket and also to have it equal length on both sides of the tub. Total time less than 10 minutes.

The replacement of the detergent grommet requires removal of the inner door panel. I removed the seven torx-head screws along the edge of the plastic panel and lifted the panel away from the outer metal door. There are wires attached to the detergent cup motor. I tried to remove them but found it was easier to simply snap the motor out of it's retaining clip, leaving the wires attached. The inner door panel can now be removed. The detergent/ rinse aid module is removed by taking out two hex-head screws. It lifted away from the door and the grommet is right on the front, surrounding the detergent cup latch. I removed the old grommet, cleaned the residue of old detergent and water hardness from the latch and the backside of the inner door. and placed the new grommet over the latch. I used a little water on the new one to make it slide on easier. I then reattached the module to the inner door. Be sure the grommet is centered in the square hole and evenly tighten the two hex-head screws. Re attach the soap motor by snapping it in place being careful to align its plunger correctly with the soap module. There is a groove in the plunger that fits into the plastic arm of the module. Re assemble the inner door and tighten the torx-head screws evenly. This job took about 30 minutes and completely solved the leak problem.

The broken spring linkage requires partial removal of the dishwasher. First, I turned off the power and water as a precaution. I removed the undercounter philips head screws, removed the lower access panel and kick plate using a nut driver. To access the door spring mechanism, the dishwasher must be pulled out from the cabinet about 10 inches. I had flexible electric and water lines so they didn't need to be disconnected. If the water and electric are rigid, then they have to be disconnected. This may require a professional. The replacement of the door springs and linkages is very easy once the dishwasher is pulled out. Keeping the door closed and locked, simply hook one end of the spring on the linkage, attach the other end of the linkage to the door and attach the other end of the spring to the hole in the dishwasher base where the old spring was attached. It is a good idea to replace both springs and both linkages to keep equal tension on both sides of the door. Slide the dishwasher back to it's original position and replace the undercounter screws and the lower access panels. Total time less than 15 minutes.
