Grant I Lombard , IL March 14, 2017 Appliance: Maytag Dishwasher MDB6000AWB Maytag Dishwasher Mdb6000awb: Upper spray arm fell off!. How to replace Upper Spray Arm/Retainer. Found the retaining clip on the parts list. Watched the videos to figure out how the upper arm attaches. Tried cleaning out the terribly clogged upper arm. Then looked at the lower wash arm--WOW! Talk about ugly clogs! Watched second video to see how that lower arm comes off. Got the lower arm off and realized all the gunk I was able to poke out of the holes would just come back, so replaced both spray arms. YES, the upper arm includes the retaining clip!! Parts arrived in 1.5 days. Installation was a snap. BUT--now the increased spray action reactivated a semi-dormant door leak. Ended up replacing the door gasket, which stopped the leak. YAY! DW back to like new!! Thanks to APPros.com!! 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
