Jason H Fort Wayne , IN February 24, 2016 Making a mechanical noise and not pumping any water 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. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
