How to Troubleshoot & Replace Bosch AP2802376 / 00167085 Circulation Pump Repair Kit

Our Bosch suddenly quit washing the dishes properly after 15 years of faithful service. I observed that there was no pressure coming from the sprayers, and determined it to be the circulating pump. I could reach into the pump from inside the dishwasher and could feel that something was loose in there - the impeller moved when pumping, but I could stop it with my finger. When I took the pump out and disassembled it, the impeller was in two pieces (the front and back pieces that are supposed to be fused together). I also saw that part of the rear pump housing was broken off (the thinnest part where the water enters the pump). I ordered the repair kit and the rear housing and rebuilt the pump. This is not a difficult process - AppliancePartPros has excellent tutorial videos for both the repair kit and replacing the pump. Please note: The wiring colors shown in the video may be different than your model. TAKE PICTURES of all wiring before you disconnect any wiring. Do not follow the video wiring instruction - just document your wiring, disconnect it, and make sure you reconnect it the same way. You will need to disconnect and reconnect the wiring at the same places they show in the video, it's just the colors and terminal positions that may be different. All other instructions in the video are spot on. NOTE: You should probably remove the pump drain cover (which is attached with one screw at the bottom of the pump, just to make sure there are no blockages. This was not my problem, but I did find that the drain was about 60% blocked, and partially by a silicone rubber stick-on foot that had apparently fallen off of a cutting board. CAUTION - When you remove the sump from the bottom of the dishwasher, that stainless lip is VERY SHARP! You can cut yourself badly if not careful. There are sharp metal edges on the stainless parts under the dishwasher, so please use caution. This is not a difficult repair job. Bosch has done an excellent job designing this dishwasher. Every removable screw is a T20 Torx screw, so that is the only bit you'll need. You will need a 2" worm clamp to replace the OEM clamp on the pump - that one has to be pried off and cannot be reused. You will need an adjustable wrench and probably a socket set to disconnect the dishwasher's supply and drain lines, and you will probably need a Philips screwdriver to remove the under-counter screws holding the dishwasher in place. This repair cost about $100, which is way cheaper than buying a new dishwasher. If you are handy around the house, do not be intimidated about doing this yourself. If you can install a ceiling fan, I'd say you can do this repair. Thanks to AppliancePartPros for their help as well. Their online chat is a great service to us DIY'ers. 

First... You Guys Are Awesome... I cannot give you a better Qudo than this!! I am Steve, Janet's' husband and the fixer geek around the house.. We had troubles with our Bosch Dishwasher... (not a new one by any chance)... and parts in our City (Denver) were non-existent. So referring to your website.. I found your video on "Repairing the Circulator Pump on a Bosch Dishwasher" and you guys nailed it!! The video took me step by step though the disassembly and repair in the most complete video I think I have ever seen. (and I take trucks apart for a hobby) It showed everything from the removal and disassembly...right down to replacing the parts. We ordered a Circulator Impeller repair kits with the impeller, o-rings, and seals... everything fit just like the old. The old impeller was worn out and separating and simply no long pumping water. The video.... so well done.. took us through the re-assembly.. and the dishwasher runs like new. I ordered the parts... you had them "IN-STOCK and I went ahead and got them overnight... and got my wife's kitchen back in order in no time at all. QUDOS to all on your team. We need more companies like yours that take time to help us Do-it yourselfers out here get things done. Yes... if we had to pay a repair firm that changed $80-$100/hr. it would have been cheaper to replace the dishwasher entirely....as it took me maybe 4 hrs total... and a lot of that was learning curve...but with your video... it was great. Your parts prices were 40% lower than ordering them in town and waiting 5 days... Janet has a dishwasher that will last another 15 years and it cleans fantastic again. Thanks for all your help... keep up the great website!! 

I could see that the circulation pump was running, but no water was spraying. I ordered the repair kit and followed the video I found on YouTube carefully. I am generally pretty handy and this was a moderate job, it wasn't too hard at all; it just took a long time because you really have to almost completely disassemble the dishwasher. The only problem I had was that the plastic fill tube/hose was so brittle that it cracked when I removed it as part of the disassembly. When I reassembled the dishwasher it leaked. So I had to wait an extra day for that replacement hose to arrive before I could button everything up and use the washer. 

The impeller seemed the likely failure so I Googled my product number and found videos on how to access the impeller. I disassembled the dishwasher before ordering any parts in case other parts failed during the process as the dishwasher is 10+ years old. The impeller is a two piece construction and it had separated inside its housing. I ordered the repair kit for my model on Monday and it arrived Tuesday morning. Back washing dishes that afternoon. 

I researched the internet on the symptom, and AppliancePartsPros.com advised the most common problem was the Circulation Pump...seals and broken impeller. It was only by watching AppliancePartsPros.com's repair video, that I was able to accomplish the actual fix. It took about an hour to get to the old circulation pump, and once I had it apart, it was quite obvious the impeller and the bushing seals were toasted. I replaced all the circulation pump parts, replaced the water inlet valve for good measure, and the lower spray arm for as my original was cracked, and the unit is now performing just like it did when we purchased it 10 years ago. 

Watched AppliancePartsPros video, disassembled the dishwasher and replace impeller and seals. 

I did it myself. I replaced the impeller. It took me about three hours to do it 

After ordering this part I realized that that probably wasn't the problem, so I ordered another part from you (water inlet valve) which solved the problem and was a much simpler repair, I hope you don't mind but I am sending this unused part back. Thank you 

Bought replacement detergent lid and circulation pump impeller online. The detergent lid was easy with the online video. The impeller was much harder, I never would have been able to do it without the video. It took a long time, much of which was related to peculiarities in the way my dishwasher was installed. But even apart from that, you really have to take the thing apart to do this job. I'd recommend marking any wires you disconnect because mine didn't correspond exactly to what was on the video. All in all, though, the fact that this company has the exact right parts and detailed videos makes for a very effective way to do business and I highly recommend using it. 

I serviced the circulation pump on our Bosch dishwasher using the circulation pump repair kit. While I had it apart I also replaced the lower door seal that I had wanted to do before. I should have ordered the non-return valve at the same time and just planned to replace that too (since it is such a cheap part). The housing that the repair kit goes into was a bit worn away but I swapped in the new parts and it seems to be pumping/working correctly. Great customer service. Fast shipping.
