Water Leak Lower Left, Bottom Of Door
Removed the old gasket. It was easy to "pop out" the parts that held the gasket in place with a regular flat blade screwdriver. Becareful not to chip the porclien (sp). Any of the tabs that broke off I just pushed them through and can take them out if I ever need to remove the front of the door. Works fine and no leaks. Clean the area of the old gasket so the new gasket will have a good seal. End of story.

Both outside door handles turned very beige
Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you

my wife said no water coming to dishwasher!
i took off the kick plate and found the water valve. its the piece that water comes to from under the sink to connect to the dishwaser. it has a plug with 2 wires. i turned off the water supply, disconnected the wires(probably should have flipped the breaker but didnt) took out the 5/16 mounting screws, had to use a little end wrench on 1 because it was behind the water line and a nut driver on the other. i put some thread gook on the connection and put the new one in the way it was and it works great. i am writing this because thats where i got the info to diagnose in the first place and saved me $$$!

Detergent Cup did not work
I would recommend getting the entire unit. I could have replaced the electrical component only, but the other parts were deteriorating.

I removed the 4 screws in the lower side of the door and removed the front.

I lossened the 6 screws holding the detergent cup. This was done with a small hex wrench.

I replaced the dispenser and connected the wires back onto the electrical sensor.

I put the front back on the door and tested the repair. Worked fine

I will be replacing the door gasket next. I found evidence of leakage when I removed the front of the door to replace the detergent cup.

No water flow to upper wash tray
The cap.nozzle is critical in transferring water to the
upper wash tray in the "heavy wash" cycle only. If this part is defective, simply unscrew it by hand and install the new one by hand in seconds. This
part is inactive in the "light wash" cycle.

Look for deteriation in the black rubber area of the
cap. nozzle.

Ordering and tracking the shipment was a breeze,
everything was very easy to do !!!!

dishwasher was leaking through the door.
All I had to do was take apart the door by removing a few screws. Then ripped the old gasket off. I then lined all the tabs up to make sure it was going to fit and then started pulling them through with needle nose pliers. When the door was reassembled I checked the plastic piece where the gasket ends in the tub and found some loose screws that needed to be tightened. After that I ran a few cycles and it does not leak any more.

the door gasket was leaking
Easy to change. Just pull firmly on old gasket, clean surface with soapy water. Align tabs on new gasket, push into place a tap firmly with handle of a screwdriver and taps pop into place. Was done in about 40 minutes.

Upper Spray Arm broken off
It was so easy , I first put one side of the clamp on the little rack area in the center of the upper rack then pushed the other side on. It took less than five minutes. No tools needed. Julia

The detergent cup would not latch closed
The repair was fairly simple. The hardest part was figuring out if this was the part I needed or not. After studying the inerds of the dishwasher door and the detergent cup mechanism, it seemed like this part would do the trick.

Here's how the mechanism works . . . the plastic stopper at the end of the bi-metallic strip latches the detergent cup in place. If these strips are bent away from the spring mechanism / plastic cam enough, the stopper will not latch on the cam (as was the case with mine). So, I needed to replace the bi-metallic strip. This part comes along with a new cam and spring.

The actual replacement of the parts is simple. The parts come with pretty good installation instructions.

Good luck . . .

intake water valve was stuttering causing water hammer
First I shut off the water intake. Then disconnected it from the valve assembly. Then disconnected the hose on the other side of the valve assembly. Then removed and replaced the valve assembly, disconnecting and re-connecting the 4 wires attached to the 2 solenoids. Then re-connected the water intake and hose. Then turned the water back on.

Then, noticing it leaking slightly, had to do it all over and include a small amount of teflon tape on the brass fitting that screwed into the valve assembly.

Phew.

the motor would not run.
i determined that the impeller was not free. ordered and installed an impeller kit which included a new bushing, which was the culprit. it was a fairly simple fix, needing only to remove the pump housing from the back of the motor. access to the impeller was by removing the screw-in, x shaped connection on the back side of the impeller housing. runs like new again. the fix was far less expensive than a new washer.
