  • Disconnect power and shut off the water supply before servicing
  • Open the dishwasher; remove the upper rack if needed for access
  • Release or unthread the retainer and pull the old arm straight off; clear debris from the hub/feed port
  • Seat the new arm and secure the retainer hand-tight; ensure the arm spins freely and run a test cycle
