Ken K The Colony , TX January 17, 2016 Spray not working on ge dishwasher I typed in the serial # of dishwasher, found pic of the part and ordered on Wednesday. Part arrived on Thursday afternoon [ standard shipping] and it took maybe 5 minutes to unscrew the old spray arm and install the new one. Easy peasy. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
