Bosch 11064386 Water Inlet 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.

It finally gave E15 code, then after drying out the E15 code came back within 5 minutes of running. I dried out the base then I ran the dishwasher and observed water coming down the overflow chute after running only 5 minutes.There is a water inlet (clear water chamber on the side of the machine). It had some gunk inside that was stopping a black float shut-off from moving. I replaced the water inlet chamber. I also suspected the non return valve (also called a check valve). From the parts diagram I could see the valve is inside the hose connection inside the sump. This is criminal because previous Bosch models and most other brands have the non return valve accessible after removing the filter. There is usually a cover that allows you to remove and replace the rubber diaphragm from inside the tub. I almost think this is planned obsolescence!! They know this is a service part at least once in the life of a machine. Anyway, this Bosch model requires you to remove the whole bottom of the machine because the hose is captured by a "U" shaped protrusion that is part of the base. There is a ridge in the hose and then the hose sits down in the "U" so the hose doesn't slide out. Instead of removing the machine base, I cut off the left side of the "U" at about the 9:30 position and wiggled the hose out easily. The check valve is clicked inside the sump by a slight ride inside the sump outlet. They make it very difficult to remove without damaging the inside of the outlet. The check valve needs to be spun counterclockwise about 1/4 turn releasing it from the ridges. This will be a bit of a fight with tools you may have on hand, Be careful not to scratch the inside of the sump outlet since the O ring on the hose needs to seal to this surface. After removing the non return valve I drilled a 1/4" hole in the U shaped protrusion in the 4:30 position (relative to the hose), to allow a zip tie to pass through. The new nonreturn valve has a straight rib on the inside of the valve. This rib will point down to the 6:00 position when the valve is installed correctly.Be sure to install the new valve with the rubber flap toward the sump. I installed the valve so the rib was pointed down to the 6:00 position. I then used a small flat screw driver on the edge of the valve to pop the valve past the ridges inside the sump outlet. The ridges are really small. If you see one ride peeking out past the valve you have pushed it in far enough. I installed a new hose using silicone grease inside the sump outlet. You can get silicone grease at a scuba supply store or on Amazon. Use the grease on all hose connections that have an O ring connection. Since replacing the water inlet chamber and the check valve the machine has worked fine. I noticed the rubber diagram-flap on the old non return valve was bent inwards so I suspect at times it was not closing.

First, let me say that Bosch's tech support line told me my replacement of the water inlet distributor wouldn't fix the problem. I ordered this part from another supplier and it came without the flow meter sensor. Bosch says that there isn't a different part with or without the flow sensor, however their original part did use and connect electronically to the flow meter sensor. This sensor tells the dishwasher how much water has flowed through this part. Because of the missing flow sensor I came to the Appliance Parts Pro's and ordered the exact same part number as the other place. However this time the part from Appliance Parts Pros DID come with the flow sensor. It was a very simple replacement, one big nut that holds this part to the side of the appliance, two drain hoses and a fill water hose, plus a simple push on electrical connection to the flow meter. Took about 10 minutes, taking my time to make sure everything was tight before I tested water through it. Ran a cycle in it and it ran perfectly. Bosch is wrong on their own part, this part does have an impact on the water draining OUT of the unit. Thankfully I didn't call a repair service as this same process would of cost me a couple hundred dollars in trip fees alone, much more by adding their troubleshooting time. It's easy fixes like this, which Appliance Parts Pros help support with replacement parts that makes me feel like I am capable of performing my own repairs for a LOT less money!!! Thanks Appliance Parts Pros!!!

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.

I watched the AppliancePartsPros videos that were extremely helpful. I studied the problem and then order the parts. They were easy to identify in the explosion drawings and ordering was a breeze. I paid for fast shipping and the parts showed up one and half days later. Repair was a breeze because I had watched the video. Parts were a bit cheaper on a different site but I honor the value of the videos and definitively the fast shipment. This is not the first order and I will always come back!
