Water dripping from right corner of door

  • Customer: Tim from Ringgold GA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver

Took out about 7 torx screws to remove the inner door liner. Discovered evidence of leak coming from the sop dispenser latch, and noticed the grommet had turned soft and was torn. The grommet is only about 1" square. Used nut driver to remove two screws to remove latch assembly. Slipped old grommet off and put new one on, and reattached the latch. The foam seal at the bottom of the door looked worn, so we replaced it with weatherstripping from home improvement store. The main door seal was brittle, so we replaced it too - just grab an end and pull the old one out. The new one was installed by starting at one end and we just pushed it in place. We used a nut-driver to push it in - we were afraid a screwdriver might damage it. The new door seal required us to latch the door to get it to stay closed the fist couple of days, but now it has loosened up a bit and works as expected. And NO MORE LEAKS. Cost is much less than a new unit!

Using the pliers, my husband pulled out the old gasket to get it started. He then pushed the new gasket in with his fingers and used a screwdriver to press in the ends. That's it. Pretty easy. I ran the dishwasher a couple of hours after he installed it and there were no leaks. Still not leaking. Seems a bit quieter since the seal
is better.

I was secretly hoping for a new dishwasher eventually. But it makes much more sense to shell out $43 for the gasket rather than spend the $600 or better for a new dishwasher!

I found the website very easy to use as well. Everything shipped quickly and there were no problems at all. I will bookmark this in favorites should I need it again!

Water leaking below door

  • Difficulty: Easy

I originally thought the door gasket was leaking so I went to partselect on line to order the gasket. After seeing the repair story results, I also decided to order the soap dispenser grommet also. I first relaced the door gasket as that takes about 5 minutes (take the easy way first right,) I was wrong as it still leaked. I then took the 7 torx head screws off from the door and the inside section just lifts off exposing the underside and the real problem. The soap latch had been leaking and was obvious from the dried soap/water trail. You have to remove two small screws and the whole unit comes out very simply. I took the extra time to clean off the build up of soap and hard water before replacing the seal and remounting the soap dispensing latch assembly. Ran another load and no more leaks! Thanks for the advise and the really simple but accurate way to order parts. I will use this site if I ever need any other parts. Very helpful and quick deliver as well as reasonably priced.

Observed the way gasket was installed including slight overhang on each side.
I simply pulled out the old gasket, starting at one end. I then wiped down the area with a dampened rag and pressed in the new gasket exactly the way the old one came out. It is important not to stretch it, just push it into place ending up with the same overhang on both sides.
Total time less than 5 minutes with no tools.

Roller disconnected from upper rack, due to a cracked clip

Once I figured out how to get the endcap off the roller track (allow several minutes, because it was designed by some dork), I slipped the old roller off the track, put the new roller on, and clipped it to the rack. Then I put the track cap back on (really easy once you've figured out how to get it off) and it was good as new.

As for how the cap comes off, it's difficult to describe. But it may help you to know that the cap, despite what it looks like at first, is actually surprisingly long and folded on top of itself. Pulling it directly out doesn't work; you have to unfold it before there's any chance of getting it out.

dishwasher door leaks

I ordered and replaced both the door gasket (easy) and inner door seal (difficult) to try and correct a leak during operation. The door gasket was easily replaced. However, the inner door seal was a bit more trouble. After removing the inner door I found that the old inner seal needed to be removed and surfaces thoroughly cleaned of old build-up of dishwasher soap residue, in order to allow the sticky back tape side of door seal to properly stick to the door. There also was a plastic cover over the wire bundle that needed to be cleaned. The inner door seal was the exact length, so proper positioning of the sticky back was very important.
Upon reassemly the leak still existed and I was unable to correct the leak. Further inspection indicated that the basic tub/body of the dishwasher might be slightly distorted due to age and may not create seal with door seal as originally designed.
I guess I need to find a new dishwasher, at this point.
A word to the wise: Check to see if the tub/body is still in good condition.

The Soap Dispenser would not open duirng wash cycle

I suspected that the wax motor had gone bad based on reviews I had read. The repair requires a TORX bit to remove seven screws holding the plastic cover on the inside of the door. I sat in a chair with the door resting on my knees and took the screws out. Once open, the two wax motors are under the cover and easily accessible. You simply pull the wax motors out and detach two wire plugs. You should note how the wires are attached. The wire plugs were a little difficult to pull off but with a little effort they came straight off. Once new wax motors were installed, the soap dispenser opened.

I was also using a gel dishwasher detergent and was told that, for some reason, it might have begun to act like glue and this might also have prevented the soap dispenser from opening. I switched to powder and that did not solve the problem leading me to replace the wax motors. The soap dispenser spring seems a little weak so I have continued using powder.

Water under the dishwasher

  • Customer: Kurt from North Ogden UT
  • Difficulty: Easy
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers, Wrench(Adjustable)
  • 25 of 26 people found this instruction helpful
1. I removed the covers below the door and watched during a wash cycle to see where the water was leaking. There was a small pinhole on the rubber connector at the end of what turned out to be the "top shower hose". I was hoping I could just replace that rubber connector, but apparently it is permanantly attached to the entire "top shower hose" assembly.
2. To remove the top shower hose I first turned of the circuit breaker to the dishwasher.
3. I needed to slide the dishwasher about half way out of the cabinet, requiring removal of two screws at the top of the dishwasher attaching it to the counter.
4. I also had to turn off the water and disconnect the water supply hose (at supply valve, not inside the washer) because it had no slack to allow the dishwasher to slide out of the cabinet.
5. I removed the hose clamp at the bottom of the dishwasher.
6. I removed the top dish rack (there are clips on the ends of the rails that can be opened to allow the rack to come out).
7. I popped off the upper washer arm by fiddling with the clip mechanism. Then I removed the threaded "nut" holding the hose in place.
8. As others mentioned, it is good to remember to save and re-use the hose clamp and rubber washer.
9. Removed the old hose.
10. Ordered new hose, waited for delivery. Kids washed dishes by hand for a few days.
11. Installed the new hose. Replaced the rubber washer at the top end and fastened with the "nut." Replaced the washer arm and top dish rack.
12. Connected the bottom end of hose, re-using the hose clamp.
13. Positioned dishwasher back under cabinet and replaced screws.
14. Re-connected the water supply hose.
15. Turned circuit breaker back on.
16. Began using dishwasher again. Observed a few wash cycles to ensure no leaks.
17. Re-attached the covers below the door.
18. Done.

Dishwasher leaks water

  • Customer: Andrew from Northfield OH
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver, Screw drivers
  • 22 of 26 people found this instruction helpful
I removed the two plates located below the dishwasher door to expose the float switch. I removed the two screws holding float switch, I removed screw holding switch actuator, then I removed float assembly.
Installed new float assembly, but could not use the float palnut, it had too small of a hole, I substituted a larger one that fit the float better. Note I fitted the palnut to the float (the nut cuts it's own threads in the float) before installing the float. This made installation easier. Next I transferred the two wires from the old float switch to the new float switch in the same positions as the existing switch wires. Then I installed the float switch. Finally, I cleaned up the float switch actuator and screw so that the actuator moves freely on the screw. I then installed the float switch actuator and ran the dishwasher to check for proper operation. Note: this float and switch control the water level in the dishwasher. If the actuator sticks, the dishwasher will fill with too much water and leak. If the float has collected dirt inside, it will weigh more and the water level will be too high, causing the dishwasher will fill with too much water and leak. If the switch sticks or fails the water level will be too high, causing the dishwasher will fill with too much water and leak. That is why I relaced the parts: float and switch. I don't want to go back and work on this again.
Lastly, after a few days of proper operation, I installed the two plates located below the dishwasher door. Job done!
