O-Ring (Seal), 1
Genuine Whirlpool part
By: Whirlpool
Part Number: WP99002003

This O-ring creates a watertight seal in your dishwasher's wash or drain system, helping prevent leaks and maintain proper water pressure. Replace a brittle, flattened, or damaged ring to restore a reliable, leak-free connection.

  • Provides a watertight seal between mating parts such as pump housings, fittings, or hose joints
  • Helps stop drips and seepage caused by a worn or deformed seal
  • Common symptoms: water under the unit, moisture around pump/tubing connections, or leaks after reassembly
  • Replace if the old ring is cracked, cut, flattened, or hardened
What's included: 1 O-ring Install notes:
  • Disconnect power and turn off the water supply before servicing
  • Place a towel or shallow pan to catch residual water
  • Clean the groove and mating surfaces; lightly moisten or use a manufacturer-approved lubricant to help the ring seat without pinching
  • Seat evenly, reassemble without overtightening, and run a short test cycle to check for leaks
