Bosch 12008381 Circulation Motor And Heater Assembly OEM Part

This was to address an E:09 fault code on a Bosch dishwasher. I swapped out the Circulation motor and heater assembly. The video given on APP.com was for a different model, but more or less the same. The video gave me confidence enough to order the part and attempt it. The significant difference was that in the video, the assembly is easily accessible from the bottom of the unit. On my unit, however, the bottom is a closed plastic pan that isn't easily removable, likely requiring removal of the door and it's counter-weight springs and cables. It took a lot of study before determining that the motor could still be swapped out without major disassembly to remove the bottom pan. We used a flashlight and the phone's camera to take several pictures before we had confidence on where everything was located (especially the hose clamp) and if they were reachable. The dishwasher is set on the right side to reach and break the factory hose clamp, then on the left side to finish. The plastic box that holds the control board assembly needs to be popped out, but not disconnected, then the connections to the Circulation Motor and Heater Assembly can be removed, and the pump pulled off of the hoses. It can be difficult to get hands, light and tools in there and water still in the dishwasher will leak out, so have towels ready, both for water and to avoid scratching the floor or the appliance. Positioning the new hose clamp properly was a concern, as well as having confidence that both the inlet and outlet were connected and water-tight. The screw for the hose clamp could be better designed, perhaps if it took a nut driver instead of an eye-glass hinge sized screwdriver. If there were a way to test for function and leaks that before putting the unit back under the counter to connect the hoses, that would be helpful.

The part arrived quickly and I got right to work. I had to buy a T20 tool to get the door front off, but had all other needed tools. Getting the dishwasher out of my cabinet was hard but that had more to do with how tightly it was fitted and some layers of uneven flooring that got stuck as we tried to pull it out. Once we had it out I realized we didn’t have the same easy access to the circulation/heat pump as in the video on this listing. Ours was in the middle of the bottom of the dishwasher and required a 15 step process to remove the bottom of the dishwasher before the part could be replaced. I was about to give up since I had no idea how to take the bottom off until I found another video with nearly my exact dishwasher (on Appliance Parts Pros) that showed the steps to take everything apart and put it back together. Once I got to the actual part, which took minutes to switch out, it was super easy. Putting the dishwasher back together was a bit more challenging — the cords for the door springs fell off during repair but I found another appliance parts pros video that showed me how to put those back on— but luckily everything eventually came back together and thankfully the part replacement fixed my issue. Unfortunately now the ancient water shut off valve for the dishwasher that’s in my basement is leaking and needs to be replaced, but that’s life! I saved enough money repairing the dishwasher myself so I have some leftover to call a plumber. Highly recommend ordering parts from this company. Their how to fix videos are fantastic and I couldn’t have fixed my dishwasher without them! My husband is impressed and now thinks I can fix anything that breaks!

Ordered the Bosch circulation motor and circulation element (120008381) from Appliance Parts Pro to remedy issue. Part arrived within two days. Watched the video on website but quickly found that the Bosch 800 Series has a solid plastic base that requires it to be removed in order to access the circulation motor/heating element. After turning off power and water and disconnecting water and discharge pipes and removing kick plate in front, I disconnected bottom of dishwasher by removing two screws on back, removing metal plate on front bottom (retained by two screws), disconnected door cables on either side by pulling on spring and lifting cable off door hinge latch hook (no need to remove door). I also removed power cord from back of base. Then I removed door cable guides to access metal tab behind them and pushed them in slightly to allow metal frame to lift up from base. Then, with dishwasher on its side, I gently separated the base from upper metal frame, removing discharge hoses from base retainers (they just slide out) and also slide power module out of base to allow separation of base from upper frame (note: I did not completely remove base, just pulled it out far enough to access circulation motor/heating element). Removal and installation of circulation motor/heating element same as shown in video (I.e., remove clamp, remove the three electrical connectors, twist out motor while disconnecting rubber bushing, install new one in reverse). Then reassemble upper frame and base by bending front tabs slightly outward to lock in when pushed back into base (put small flat blade screwdriver into small slot on tab to bend out) and placing power module, hoses put back into retaining clips in base during reassembly. Once upper frame and base aligned and pushed into place, Reinstall two screws in back, reinstall front bottom plate with two screws, reinstall door cable guides and attach door cables by pulling on springs and hook in in door latch hooks (ensure cables properly route around guides). Snap in power cable, put in cabinet and reattach water/discharge hoses. Sounds more complicated than it was, did in all in less than 40 minutes. Works great.

After researching the error code, which told me the heating element was at fault, I ordered the part overnight from Appliance Parts Pros. We received the heating element the next day. I watched a couple of YouTube videos showing how to replace the heating element. Then went to work, it took about 2 hours to install which was the length of time said in the YouTube videos. Some time could have been saved by not removing the door, as shown in the YouTube videos. I still can not figure out why they took the door off. Overall, I was happy with the service from Appliance Parts Pros and would not hesitate to use them again.

I had to replace the heat pump. Pull the dishwasher out of cabinet and pulled the pump out from the side. Helpful videos online to show you how.
