Jeffrey M San Francisco , CA May 13, 2015 Appliance: Model BOSCH SHX46B05UC/14 I noticed that dishes in the top rack weren't getting as clean as they should and as they used to i also noticed the sprayer arm woud often be stuck in the same position and didn't spin freely I ordered a center arm sprayer. It snapped in in seconds, less time than it takes to unload the dishwasher, It's cleaning like new again. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
