How to fix it

  1. Clean the dispenser cup and lid with a damp cloth and verify the lid swings freely.
  2. Power off, remove the inner door panel screws, and locate the dispenser assembly.
  3. Reseat the harness at the back of the dispenser.
  4. Test the wax motor — apply 120VAC for ~30 seconds (per tech sheet) and watch for the actuator to extend.
  5. Replace the detergent dispenser assembly if the wax motor does not actuate.
