How to fix it
- Open the dispenser, scrape out any caked detergent, and clean with hot water.
- Reload with fresh detergent (pods preferred over powder for reliability).
- Re-rack so no large items block the dispenser door.
- If the door still won't open, remove the inner door panel and inspect the dispenser solenoid and linkage.
- Replace the dispenser assembly if the solenoid is open or the latch is broken.
