James D New Market , AL November 12, 2017 Bosch dishwasher made grinding noise early in the cycle. Cause was a broken circulation pump impeller. Needed to verify that the probable cause of the noise was the actual failure, so followed the disassembly phase of your outstanding video on how to replace the impeller. Confirmed that, yes, the impeller was indeed worn out and had separated. Ordered replacement parts from your website, made easier by all the pictures provided. All of the parts arrived in three days as promised. Completed the repair by following the video step-by-step. Could not have completed this project without your excellent catalog of parts and videos. Thanks for helping me save nearly $1000 in replacement costs. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
