Common Symptoms

  • Dishwasher does not clean dishes properly
  • Fine food particles or debris reappear on dishes
  • Drain adapter is cracked or leaking
  • Internal flapper is warped and no longer seals properly

Check Before Replacing

  • Inspect the adapter for visible cracks or leakage.
  • Inspect the internal rubber flapper for warping, damage, or failure to close.
  • Check for debris that may obstruct the adapter or prevent the flapper from sealing.
