Part Number: OEM18018621
Manufacturer Part Number: WP22001186

This washer injector (lower) forms the bottom half of the fill injector assembly, channeling incoming water cleanly into the tub. A damaged injector can cause leaks or spray at the tub ring during fill. What it does:

  • Directs fill water into the tub through the injector assembly
  • Seals with the upper injector to prevent splashback
  • Common symptoms: leaking or spraying during fill, water on floor near the top/front during fill, visible cracks/warping on the injector
  • Restores a clear, sealed water path for proper filling
What's included:
  • One lower injector
Install notes:
  • Disconnect power and shut off water supply before servicing
  • Access may require lifting the top or removing the cabinet to reach the injector at the tub ring
  • Transfer any reusable clamps/retainers; align with the upper injector for a proper seal
  • Run a short fill and inspect for leaks after installation
