Do-It-Yourself Story

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.
