Diagnosing the problem, i.e. finding the source of the leak, was the hardest part. The best clue was the leak only occurred well into the cycle when the water was hot and steam was coming out the vent. I then assumed there was a bad seal and steam & condensed water was leaking down into the door. I replaced the vent duct & seal, a broken drip cover (an internal part in the door), and replaced a missing rinse aid cap. This stopped the leak.

The plastic disc which sprays the jet has snapped off. This is the disk with swirl pattern on the back face.

1) Removed the two white clips from the left and righ hand side of the top tray roller rail. this allows the tray to be completely removed and ease access to the washer assembly. The clipe looks like the letter "k", so you will need to close the "k" to almost straight line in order to get it through the hole.

2) Put a sheet or a towel at the bottom of the machine, just incase you drop the two small cross head screws. This prevents the screws from falling to the bottom of the machine.

3) Remove the screws. At this time the washer assembly will/should slip out very easily. very little force is required to pull the assmbely out.

4) Slip on the new washer assembly and put the screws back in place. Tighten screws, Be careful not over tighten the screw as you may crack the plastic flange.

Note: My machine is an older model, so the washer assembly had two screw fixing. The new assembly only had one hole. Although one fixing appeared to be sufficient, I decided to drill a hole on the other side and this worked fine.

5) Replace the top tray, taking some care to ensure rollers are correctly located within the rails. Then replace the clips and job's complete.

Old valve failed and started to leak.

  • Customer: Adam from Minneapolis MN
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers, Wrench(Adjustable)

Pulled off the old valve using a crescent wrench and screw driver. The replacement part was a 100% exact match. Slapped on the new valve and that baby was water tight. $50 on a new valve is a lot better than $500 for a new washer.

Partselect.com was so easy to use and find the right part. Way more helpful than whirlpool's site, but that's not surprising seeing as they have an "authorized repair technician" page.

Thanks Partselect.com!

first i picked out the old seal, use a screwdriver to get it started. Then I pushed the new one in after cleaning the seal channel. I fixed it during a commercial while watching my favorite tv show.

Lower spray arm wobble - poor cleaning

  • Customer: Howard from Catlett VA
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver, Screw drivers
  • 3 of 3 people found this instruction helpful
Removed the lower spray arm assembly thumb screw and lifted off the spray arm assembly. The lower seal had disintigrated - couldn't even find any pieces in the filter. After reassembly with the new seal and bearing I turned the spray arm by hand to ensure it was not binding. There was still was, what I would consider, some excessive wobble. I fashioned a shim washer out of some plastic from a Folgers coffee can lid and installed it on the thumbscrew threaded shaft and tightened it all down finger tight - it works very well and now, and no wobble.
I relaced the upper spray arm seal while I was doing the job (both the upper and lower seals are the same part #). I figured it would go out on me eventually, so I might as well replace it while I was doing the lower arm work. Kept the old upper arm seal as an emergency replacement.

Cleaned the filter screen of all debris (it is amazing what collects there over time). Cleaned the stainless tub with some spray Greased Lightning, ran the rinse cycle, and then put a few tablespoons of citric acid crystals in the soap dispenser and ran the dishwasher on NORMAL WASH with temperature boost.
Looks new inside; cleans the dishes, glasses and utensils well (no water spotting); and is nice and quite (like when it was new).

Washer was not agitating

  • Customer: Rod from Sisters OR
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver, Pliers, Screw drivers

Removed the washer from the cabinet, although the repair kit could have been replaced without this step. However, it still made it easier. Removed the spray arm assembly and the top cover to the motor. I had to block the motor to keep it from turning while I unscrewed part number 11. The rest was very self explanatory. The "impeller" was seized onto the motor shaft (20 years old) so I had to use a chisel to break what remained off, then clean some corrosion from the shaft. The repair kit worked and the pictorial parts diagram that came with the kit was very clear. Bottom line: "Easy peasy, lemon squeezy!" Great web site for diagnosis and parts diagrams!

I had a broken spray arm on the dishwasher and though i would have to spend $450-$500 on a new dish washer, i ordered parts from part select(even though i was not 100% sure if it will work), the parts were shipped super fast and arrived in 2 days, i was able to replace the broken part and fix the lower spray arm. Part select saved me a lot of money.

I first removed the old part. when i removed the old part i could not get the conector piece off when i when to get a new one they told me i should replace the copper tubing with the more flexable tubing because the copper tubing can kink up and possibly break from the kinking. so i screwed the inlet valve on i put teflon tape on the all the threads of the conector piece screwed it into the new inlet valve with and adjustable wrench then i conected the new tubing, and tightend it down with the wrench i slowly turned the water back on to cheak for leaks. When i saw there were no leaks i turned the water on the rest of the way pushed the dishwasher back in and screwed it into place an i was done.

First I removed the plastic bolt that holds the wash arm in place This exposed the upper ring that was worn out . I then lifted the arm off which exposed the larger ring. I replaced that ring, and then I put the arm back on and replaced the upper ring. I put the plastic bolt back in place and the repair was complete.-- Really Easy plus the dishwasher gets the dishes clean now
