Bosch 00668102 Sump Assembly OEM Part

Leak was slow but becoming gradually worse. Pulled dishwasher out from under counter then visually inspected sump while it ran. As soon as the water got very hot, I could see the sump leaking where it meets the stainless pan. Searched for the correct sump gasket without success. Turns out that the gasket is built into the sump for this model. The built-in gasket is very narrow (under-engineered IMHO which is probably why it developed a leak). Thanks to Simon's excellent videos at appliancepartspros.com I was able to pull the sump, remove all the critical parts (diverter, circulation pump, drain pump and aqua-sensor) and then "rebuild" the sump system. The most perplexing part was figuring out how to remove/install the water diverter since my internet searches were unsuccessful. You need to locate the locking latch on the perimeter of the circular diverter housing. Make a mark on the housing and the sump so you remember the correct orientation. Now, while you release the locking latch push down on the circular housing while you turn it counter-clockwise (?) and pull the entire diverter assembly from the sump. Installation is just the reverse except you need to make sure that you properly orient the diverter into the sump housing before turning clockwise and hear the locking latch click into place. Also you have to be very patient as you figure out how to disconnect all of the plugs on the wiring harness as to not damage any of them. Finally, just follow Simon's video on replacing the circulation pump to get everything put back together again and cross-your fingers that everything works upon testing. Only special tool needed is the Torx T-20 screwdriver.

To diagnose the problem I pulled out the dishwasher from the counter and ran it until E15 code appeared while looking underneath for source of leaking water. The water was leaking around the sump where it mates up to the bottom of the dishwasher. The youtube video provided an excellent tutorial on how to replace the sump, so I went ahead and ordered the replacement from AppliancePartsPros.com and followed the instructions in the video. The project was very doable with a little bit of time. The dishwasher is working fine now with no more leaking or error codes. Thanks for the quick delivery (2 days) of the replacement part and for excellent youtube video instructions!

I ordered the twirly thing first and put in it still didn’t hold. So then I ordered the part that the twirly thing attached to I believe it was the sump I put that in definitely not as easy as the twirly thing but no problem note though have a phone or something to take pics of the wiring cause a few of them can go in the wrong slots!!

1) Large o-ring gasket between sump unit and underside of the tub, stopped leaking for a few weeks, then began dripping from another location. 2) Replaced sump housing, has fixed leak so far. AppliancePartsPros video was extremely helpful, followed it step by step. Not a simple job. Three hours+ from pulling the dishwasher out to fully reinstalled and ready to run. DIYers do need to keep in mind that professionally made technician repair videos, while very helpful, always portray best case scenarios and feature technicians that know what they are doing every step of the way, so it will invariably look easier than the real-deal DIY experience.

I found a small amount of water leaking between the bottom of the metal basin and the sump. The gasket was failing. I bought the sump assembly, it came with a gasket. I had to take my time, it was involved. I watched the how to video first, then again when I did the repair. I put everything back together, tried the dishwasher, no leaks. I forgot to connect one electrical connector, and had to pull the dishwasher back out and connect wire harness. All is good now. It took me 3 hours. It would’ve been 2 1/2 if I hadn’t made the one mistake. I’m pleased.
