How to Fix / Troubleshooting

Safety: Unplug the unit and wear gloves if mold is visible.

  • Deep clean tanks: Wash clean and recovery tanks with warm water and mild detergent. Rinse thoroughly and allow to dry completely.
  • Flush system: Run a tank of clean water with a small amount of approved sanitizer through the spray and recovery system, then flush with plain water.
  • Drying: After use, always empty tanks and run the suction for a short time to dry internal passages. Store the unit with tanks removed and covers open to air dry.
  • Replace filters: If filters smell musty, replace them with new Vorwerk filters.
