✓ Installation Tips

Disconnect power to the dishwasher before servicing. Remove the lower rack to access the spray arm. The spray arm typically snaps or screws onto the center hub — note the attachment style before removing the old part. Rinse the new spray arm before installing. Restore power and run a short cycle to confirm even water distribution.
