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.

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

Leaks out and below the front door
First of all, rather then spending the 44 dollars on the main door seal simply cut yours in halve and trim a quarter of an inch from the disintegrated ends and use superglue and glue these ends together. this glued end will now be up top and in the middle and new clean ends will be down in the corners. next I removed the plastic door panel using a torxhead screwdriver, I just stuck the new inner foam pad on the old one. Then I glued rubber washers to the inner frame about 1/8 thick in the top 2 corners only. Finally I reattached the plastic door being careful not to tighten the torx head bolts just tight enough. It's dry and working good.

Drain hose leaked
First I had to unhook the electric, water line and drain hose. Then slide out the dishwasher. Took several days to find the drain hose - local stores only carried a 6 ft hose and I needed a 7 ft. Once I found it online, purchased it and recieved it I put it all back together and all is good.

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 . . .
