Bosch 00751456 Fill Hose 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.

I found a slow drip coming from the water inlet valve. This was the source of the E-15 message. The water collected around the styrofoam disk, which then tripped the leak sensor. It was easy to replace the valve, following the video instructions. At the same time, I decided to replace the two door seals, due to periodic leaking in the front of the dishwasher. The lower door seal replacement procedure was long, but the video was very helpful and thorough. The larger, upper door seal was very quick to replace, but there was one problem. The video did was not clear as to the proper orientation of the blade seal with respect to the seal taper. I first installed the seal with the taper pointing outwards. The result was leakage and noisy operation. I found a second source that specified a definite orientation of the seal; that the taper should be pointing inwards. After turning the seal around, the leaking stopped and the dishwasher ran quiet. Success! I suggest that you update your installation video for the upper door seal to make this more clear. Thanks.

Pulled out dishwasher, inspected, found water sensor doing its job sending E15 code. Found leaking water inlet valve. Replace valve, hose to side housing and the side housing itself due to clogging. It took 30 minutes to replace everything and works like new. Everything fit and couldn't ask for more.

Replaced leaking inlet, pump outlet, and drain hoses that were damaged by a rodent. Ugh

Removed the existing valve and hose, replaced the 2 wires, and installed new hose and valve exactly as I removed the old one. Unit worked perfectly afterwards.
