dishasher Soap/Rinse Dispenser

  • Customer: George from Fond Du Lac WI
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 11 of 17 people found this instruction helpful
The latch on the soap dispenser got worn out over the past few years on the dishwasher. I tried just puting the detergent into it and running it as usual. The detergent was added Immediatley.. missing the proper timing that would normally dispense it properly. As a result the dishes were not coming out clean and lacked the shiny clean quality we were accustomed to . I ordered the right part, got it quickly and put it in..and were back to doing dishes and having them come out the right way...spotless and clean like they should.

Heater Element Covered in Mineral Deposits

  • Customer: Chad from Cypress TX
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers
  • 10 of 14 people found this instruction helpful
Our dishwasher sat in a warehouse for a year after our move from CA to TX. When I finally installed it, there was some sort of white mineral deposit that had built up on the heater element. I didn't notice it back in CA. I tried to get as much as possible off but it kept building. So I purchased a new heater element. It's been in for a few weeks and my wife thinks the build up is happening again.
To Repair;
Unscrew the dishwasher from the counter. They'll be one or two screws attaching the dishwasher on the underside of the counter.
Pull the washer out carefully.
Remove any dishes and the bottom rack.
Tilt washer on it's side.
Remove wire connections to heater element (They slide right off but make sure to remember which one goes where)
Unscrew the nuts that are holding the element on. I used some pliers. It wasn't difficult.
Remove old element and replace with new.
Reverse order.

With the door wide open and lower dishtray out, I pulled the old gasket out of its channel. I cleaned the channel with a rag and replaced it with the new gasket. It needed to be trimmed about an inch in order to get the door to close properly. Took me about 5 minutes. Then I removed the old bottom door gasket. Just grasped the plastic edge showing while the door is completely open. Pull outward with fingers moving toward the heating element. Cleaned this area also. Took the new gasket with notch on the right hand side of the dishwasher and pushed it into place. If you get down and look closely, you can see where the notch hooks up. The rest of the piece just slides in after that. Hasn't leaked since! No leaks AND no service call fee. Parts came super fast! So glad I found this website. I'm a housewife, you can do this!

Broke nubs off of stem when cleaning

  • Customer: Glen from Chicago IL
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers

I took the bottom parts out. This can basically be done without tools. You need a phillips to unscrew 3 screws to remove the stem. Then easily replace with the new one. Putting the spiny washing part was kinda weird because I was afraid to break the nubs off again. I took the whole bottom carriage out so I could see better, pushed down kinda hard and twisted the right way (figure out which way needs to be twisted before hand by looking through the bottom of the stem).

This was too easy. I pulled out the bottom rack, spread apart the two clips which are at the bottom of the spray arm with my fingers and pulled out the old broken spray arm. The damage was visible. Then I took the new spray arm ( which looked different but still fit nicely) and gently pushed it into place. Done!

Unplugged dishwasher and slid it out from cabinet area (be sure to turn off and disconnect water supply)

Followed delivery tube up side of dishwasher to top of tub and noticed reminents of where water ran down side of tub.

Loosened delivery tube by plastic nut inside of tube and removed. Noticed gasket was partially depleted.

Ordered new gasket, replaced and put everything back together. (Be sure to use teflon tape on water source fitting and tighten firmly). No leaks

Removed the bottom panel on the unit (2 screws hold it on) and pulled the dishwasher out about 4"--after turning off electricity to the unit. Removed the broken spring and the old linkage and replaced them with the new parts. Pushed the diswasher back into place, and replaced the bottom panel. Turned on the electricity and the diswasher door is "good as new." This is quite simple to do; just takes patience.

dishwasher racks had become old and plastic coating came off.

All I had to do was take out old racks and replace with new ones. However the top rack did require taking off the part where the water runs through, it was easy though.

I would like to comment on how quickly and efficiently the parts arrived. I placed my order on a monday morning and am pleased to report by tuesday afternoon they arrived, much to my delight.

No Water Circulating in Wash or Rinse Cycle

  • Customer: Rod from Bandon OR

  • Tools Required: Pliers, Screw drivers, Wrench(Adjustable)
  • 6 of 7 people found this instruction helpful
Removed the dishwasher from under the counter, and ran to diagnose the problem. Drain pump ran, but circulating motor did not. Ordered the replacement circ pump / motor assy, and slid the washer back in its hole.
When the new motor arrived, I slid it back out, disconnected everything, and drained the water from the bottom. Then I tipped the washer on its side, removed the old motor and installed the new one following included instructions. I did have to use the new wiring harness, and found the new one had only two leads where the original had three. I connected the blue and white leads, and left the original green loose.
All in all, it was an easy repair that could be done by anyone with a basic set of skills.
