How to fix it

  1. Ensure no towel, trim, or magnetic strip is on the front of the dishwasher.
  2. Verify the cabinet opening clears the door by at least an inch above the unit.
  3. Open the door, remove the inner door trim, and locate the auto-open vent motor.
  4. Reseat the motor harness and inspect the push arm for cracks.
  5. Run the cycle and observe whether the motor engages at end-of-cycle.
  6. Replace the auto-open vent motor if it does not actuate.
  7. If motor actuates but door does not pop, replace the broken linkage.
