Sean S Chicago , IL November 23, 2014 Appliance: Bosch SHX46A05 UC/14 (FD 8211-) The upper spray arm on my ten year old bosch dishwasher had stopped spinning After trying to clear all the holes on the original arm, the problem was not fixed. I ordered the new arm, took out the top rack and turned it upside down. The arm simply clicked in and out. The problem was solved in five minutes.
