Small / slow leak at bottom corner of dishwasher door.

  • Customer: Adam from Acworth GA
  • Difficulty: Really easy

  • Tools Required: Screw drivers

After examining the door and main seal around the dishwasher I thought everything looked okay. I looked online to order a new seal anyway and discovered from others that the leak was probably the insulation strip inside the door rather than the seal around the dishwasher. I ordered an insulation strip and it arrived a couple days later. I removed the seven screws of the interior door cover and disconnected the electrical. After removing the old insulation strip and installig the new one I reconnected the electrical wiring/plugs, put the door cover back on, and reinstalled the screws. Total time was about 15-20 minutes and the leak stopped. It was very easy and saved the cost of a repairman or a new dishwasher. I'm very glad that I "listened" to others and went with the new insulation strip.

Dishwasher would stop in the middle of a wash cycle

Our dishwasher got to the point where it would not complete a wash cycle. I found that by jiggling the door latch, the dishwasher would whir back to life. For awhile, if I put a clothespin on the door latch, somehow enough pressure would be put on the switch to keep the dishwasher going. Finally, the dishwasher refused to cooperate...so I ordered a replacement switch.

The repair was easy. I only had to remove the interior door panel, unscrew the metal bar at the top of the door and underneath the door panel, then remove the black plastic shield. After that, it was just a matter of wiggling the old switch out and wiggling the new switch.

CAUTION: Be very sure that the power to the dishwasher is turned off. I got a scare because I thought the circuit breaker was off, but I had flipped the wrong one and suddenly, with my fingers very close to the bare connectors, the dishwasher came back to life briefly. I ran downstairs and found the correct circuit breaker and all was fine after that.

Water dripping from right corner of door

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!

Tub was mysteriously slowly filling with water.

Figured out that the only thing that could be causing this was a bad inlet valve. Repair was really easy. Didn't even have to pull machine out from under cabinet. First removed kick plate. Then placed towel under the old valve. Undid the power connections and water lines (in and out). removed the to screws holding the valve to the body of the washer. With the valve free, removed the brass elbow and installed it on the new valve. Reinstalled the valve and all connections. Works like a charm.

First I did the top - getting the ends off the track is simple, flip the ends "open" like a book on each side, and remove the caps. Pull out the rack, replace with the new one and replace the caps. Bottom rack was easier once I figured out how to remove the spray tower. Grab it firmly and twist. Place it in the new rack, and roll it into the DW. I'm a fairly handy woman, and this was quite easy.

Removed two lower panels using nutdriver. Ran washer through a rinse cycle, to determine for sure where leak was coming from (under door on left). Examined the door gasket and observed buildup of lime deposits and a general depression of the gasket through years of use, especially in lower portions. Removed the old gasket observing how installed. Cleaned out groove with Lime-away and toothbrush. Washed clean using water in a squirt bottle. Dried things out using paper towels, and then pressed new gasket into place, starting at lower left. Readjusted the gasket to fit precisely end to end. Shut door and ran a drip free load.

Neither the Soap or Wax dispensors worked for years and there was water leaking from the front of the machine.

Actual i missed diagnosed the leak and ordered a very expensive door gasket. The leak was coming from shrinage of the wax resevoire o rig and the tab seal for the soap dispensor. I missed the trees the forest got in the way. The leak was dripping alond the front panel well away from the main door seal.

I cleans a the plastic surfaces and noticed a lip around the opening for the reservoire and used 150 sandpaper to remove it. Replaced the O ring, tab seal and bothe selonoids and cleaned everything. Put it back together. Works find lasts along time

Took the replacment rack out of the box and found that it was the proper one. Had to rotate out the water director tower from the orignal rack and install it in new rack which took a few seconds to figure out . it was time to discard the ailing rack! Apparently the dish soap can attack the rack materia if there is any metal exposed and rot it out like rust so when this happens time for a new one. Otherwise there are no pins to support the bowls and plates in the lower section.

I removed the seven screws from the back panel of the door (special tool) and seperated the back panel from the front. My wife held the back up and I removed the two wax motors (detergent cup and rinse aid), which were clipped in place. I had turned off power to the dishwasher, so I simply unplugged each wax motor from the wiring harness, plugged the wax motors in and clipped them in place, making sure that the wiring harness was put back in the same place. Then I put the back panel back on the door, turned the power on and tested the repair. The dishwasher worked perfectly. Thanks to PartSelect for helping me solve the problem. The parts arrived in two days!

the soap dispenser door broke off, I lost the pins and the spring.

The repair is fairly simple except that the diagram on the web site has an error - it reverses the positions of the long hinge pin and the short pin. I kept trying to do it as the diagram showed and of course it didn't work. Then I followed my instincts! The only other difficult part was figuring out which way to insert the spring but there are only a few options so trial and error was the simplest way.

Water leaking around the Inlet injector on side of dishwasher.

  • Customer: Juli from Grangeville ID

My original order was for the "Motor Gasket" in the bottom of the tub that just looked nasty. Not leaking. Replacing that was a little more complicated, but used another customer's recommendations and worked great. Ran an empty load to check for leaks and thats when we discovered that we had a leak on the side of the darn thing. So we ordered the "Injector Seal Ring. Got it in about 5 days and after installing, (2 seconds), we still had a leak! Soooo, ordered the "Water Inlet Injector". 5 days later, we have NO MORE LEAKS!!! I would STRONGLY suggest that anyone who has a leak at the Water Inlet, order a new Injector right along with the Seal Ring. The shipping and handling was WAY more than the price of the parts. I'm happy to say that my 10 year old dishwasher is running like a champ. Thank You.

After I figured out how to remove the spray arms, and filter guard (that was the hardest part) it was a piece of cake. Just a matter of snapping the spray arm into the filter guard, and replacing it the dishwasher, and tightening it with the screw in retainer. Upper arm was also easy to replace after removing the top rack.
