• Works with the control to provide zone/alternating spray for efficient cleaning
• Failure can cause poor cleaning on one rack or water spraying from only one arm
• May produce repeated clicking/grinding from the sump area or extended cycles while indexing

• Disconnect power and shut off water supply before servicing; expect some residual water
• Access the diverter at the sump/pump area; follow your model's service procedures
• Ensure seals/O-rings are properly seated and parts are aligned before tightening
• Run a short test cycle to check for leaks and confirm both racks receive spray
