David K Sacramento , CA March 29, 2021 Appliance: Bosch Dishwasher SHE3ARF6UC/21 Bosch Dishwasher She3arf6uc/21: Dishwasher would stop mid cycle. How to replace Middle Spray Arm. Repair man suggested replacing the lock. Your video was helpful but my model had front controls and a two piece front door cover. Removed both sections and followed the video instructions. Also replaced the mid level spray arm - was a snap! Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
