Common Symptoms

  • Upper or lower spray arm receives little or no wash water
  • Dishwasher cleans poorly when the diverter disc is worn, damaged, or slipping
  • Water may be routed incorrectly between wash circuits

Check Before Replacing

  • Inspect the diverter disc for visible cracking, damage, or evidence that it is slipping on the diverter-motor shaft.
  • Check whether the diverter motor operates while the dishwasher alternates wash-water routing.
  • Confirm the complete dishwasher model number before ordering, because compatibility is model-specific.

Pro Tip

Inspect the diverter motor and disc together if water routing remains incorrect after replacement.
