How to Troubleshoot & Replace Bosch AP4339548 / 00668385 Middle Spray Arm

The installation of the parts was easy, especially after watching the videos that accompanied the parts description section on your website. They were very helpful. 

I pulled the spray arms and noticed that both the spray holes and the jets were clogged with minerals. Even after cleaning, the minerals would reappear as the spray arms were filled with deposits. I matched the model number of the dishwasher and found the part numbers, ordered them and they arrived 2 days later. The old parts popped right off and I was able to replace them quite easily. 

Installed the new parts- problem resolved. 

I followed the videos provided on the website. It was pretty easy to do, disconnecting the power and undoing the wires to pull out the dishwasher. I replaced both the Inlet Valve and Spray Arm. It took 2hrs. Everything is now running perfectly. I bought a water pump and heater from AppliancePartsPros.com years ago and those still are working perfectly to this day. 

New part arrived on time. Excellent service from AppliancePartsPros.com. 

Replaced, used your video, and BAM! 

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! 

We replaced both spray arms and the filter basket. Our dishes sparkle now. 

Bought a new sprayer arm 

Ordered replacement part, snapped into place, piece o cake!!
