Common Symptoms

  • Detergent remains in the dispenser after the cycle
  • Dispenser cover does not close or latch
  • Dispenser cover does not open during the wash cycle
  • Dishwasher may not clean properly when detergent is not released

Check Before Replacing

  • Inspect the cover for cracks, broken hinge areas, or damage.
  • Confirm that the cover closes and latches securely.
  • After a completed cycle, check whether detergent remains trapped in the dispenser.
  • Check that the cover spring and hinge area are present and positioned correctly; the cover alone may not correct a failed spring or latch.

Pro Tip

WP3378138 is the lid only; the hinge pin, spring, and latch may need separate replacement if they are damaged.
