Bosch 00611320 Check Valve OEM Part

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.

It took several weeks to find the very slow leak. Was getting E15 error code & water trap error once a week. I would remove water from bottom case to clear the E15 code. Then about a week later the E15 code would trigger. I discovered a leak between the circulation pump and the sump assembly housing. I replaced the circulation pump heater assembly. Also replaced the check valve while I had dishwasher apart. The repair time was 2 hours. Thanks, Dave in CT.

Ordered and replaced sump pump, backflow preventer valve and turbidity sensor on Bosch dishwasher. The latter two parts were recommended when ordering the sump pump and did need replacing. The videos showing how to remove and replace each part are great. The project went well and the dishwasher is fixed for less than 1/4 of what it would cost to get a repairman out here. In all fairness we do live in a remote location and do not have any local appliance repairmen. This is the third project I have completed using Appliance Parts Pros. Fixed Bosch dishwasher, Samsung clothes dryer, and Samsung fridge in the past year or so. All are around 8 years old. I started more DIY after being charged a ridiculous sum (over $400) by a major chain for a refrigerator sensor replacement that lasted less than 30 days. They charged $80 for the incorrect part. I bought the correct one from Appliance Parts Pros for around $30. I have been retired for some time and am able and willing to pay for competent help but looks like I will have to DIY more than I planned. I rather enjoy it sometimes. I wrote several emails to family and friends after this latest repair highly recommending Appliance Parts Pros.

First, let me say that appliancepartspros.com is AWESOME! The pricing, diagrams, videos, and ordering process are top-notch. So, the problem didn't turn out to be either the drain pump or check valve, though the videos provided by APP made changing them out a breeze. The problem was the drain pump cover. That part was not seated firmly and the small tab on the cover wasn't engaged in the sump wall. The video provided by APP for the drain pump cover shows the technician using a flathead screwdriver to press down on the cover firmly and 'snap' it into place. Now I have a new drain pump and check valve installed, the pump cover correctly installed, and we're washing, draining, and sanitizing our dishes once again! I don't want my appliances to fail, but when they do, I'll be returning here before calling in a repair technician to the house!

Wow! Appliance Parts Pros is fantastic! I first had to replace the drain pump on my Bosch dishwasher. The first one, delivered quickly, arrived with a small broken part, but Appliance Part Pros sent another one overnight express. Later, when drain problems appeared again, I looked at videos and recommendations on their parts site and realized I should also have replaced the Turbidity Sensor and the Check Valve. Another easy order, quick shipping, and clear videos on how to easily replace the parts. Three months later my dishwasher is still working like new. A Bosch service call would have cost me hundreds of dollars. I will happily use Appliance Parts Pros whenever I have trouble with any of my appliances.
