Dishes Coming Out Dirty? Replace Your Broken Lower Spray Arm — WPW10491331

OEM Part# WPW10491331 Replaces W10491331 Whirlpool · Maytag · KitchenAid · Amana · Jenn-Air

A cracked, clogged, or seized lower spray arm is the #1 cause of dishes coming out with food residue still stuck on them — even after a full wash cycle. The WPW10491331 is the genuine OEM lower spray arm for Whirlpool-platform dishwashers, directly replacing the superseded W10491331. It restores full 360° water coverage to the lower rack so every load comes out clean on the first run.

⚠️ Symptoms of a Failed Lower Spray Arm

  • Dishes on the bottom rack still have food residue after a full cycle
  • Spray arm is cracked, broken, or won't spin freely
  • Spray holes are blocked and can't be cleared by cleaning
  • Dishwasher runs but water pressure sounds weak or uneven
  • Standing water pooling under the lower rack after the cycle

✓ Part Details

  • OEM Part Number: WPW10491331
  • Supersedes / Cross-Reference: W10491331
  • Part Type: Lower Spray Arm
  • Compatible Brands: Whirlpool, Maytag, KitchenAid, Amana, Jenn-Air, Ikea (Whirlpool-platform)
  • Condition: New OEM or Used (select variant above)
  • OEM Manufacturer: Whirlpool Corporation
💡 Pro Tip — Check the Spray Arm Mount & Filter While You're In There:
If the spray arm failed due to debris impact, the lower spray arm mounting collar (WPW10498900) may also be cracked or stripped. Replacing both at the same time eliminates a second service call. Also inspect and clean the dishwasher filter assembly — a clogged filter reduces water pressure to the spray arm and will cause the same dirty-dish symptoms even with a brand new arm installed.

⚙️ Installation Notes

  • Skill Level: Beginner — no tools required for most models
  • Disconnect power to the dishwasher before servicing
  • Remove the lower dish rack fully to access the spray arm
  • Twist the spray arm counterclockwise to unlock from the mounting collar, then lift off
  • Snap the new WPW10491331 onto the collar and rotate clockwise until it locks — confirm it spins freely before reassembling
  • Do not overtighten the mounting collar nut if your model uses one — hand-tight is sufficient
  • Run a short rinse cycle and verify even water distribution before loading dishes
