John P Lawrence , KS June 09, 2017 Bits of food were stuck in the upper spray arm clogging some of the spray holes which left some upper rack dishes dirty Snapped out old part; snapped in new one. Was incredibly easy once i figured right way to get old arm out (one online video gave the wrong advice: you don't need to depress the "manifold tab" to get the old arm off; just shift it a bit to free the two hooks from the basket wires). 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
