How to Fix / Troubleshooting

Safety first: Unplug the unit before inspecting the bucket area.

  • 1. Reinstall bucket:
    • Remove and firmly reinsert the bucket, ensuring it is fully seated.
  • 2. Inspect bucket tab:
    • Look for the plastic tab or protrusion on the bucket that presses the bucket full switch.
    • If broken, the bucket may need replacement.
  • 3. Test switch manually:
    • With the bucket removed and unit unplugged, locate the bucket full switch.
    • Press the switch lever; it should click distinctly.
  • 4. Clean and adjust:
    • Remove any buildup around the switch.
    • Ensure the switch bracket is not bent.
  • 5. Replace switch:
    • If the switch fails continuity tests or remains stuck, replace it with a compatible bucket full switch.
