  • Restores proper sealing after disassembly for service or part replacement
What's included: One O-ring seal Install notes:
  • Disconnect power and shut off the water supply before servicing
  • Remove surrounding components carefully to avoid damaging the seal seat
  • Inspect the mating surfaces for debris or damage; clean before installing new O-ring
  • Lubricate with a compatible, appliance-safe lubricant; do not use petroleum-based products unless specified
