Detergent residue left on carpet, causing stiffness or white marks after drying

Safety: Unplug before cleaning filters.

• Adjust detergent mix: Follow Zanussi guidelines for detergent concentration; do not exceed recommended dosage.
• Rinse cycle: Refill the clean tank with plain water and run a rinse-only pass over affected areas while maximizing suction passes.
• Improve suction: Clean or replace filters and ensure the dirty water tank is not full and is correctly seated.
• Multiple passes: Make several dry passes (suction only, no spray) to remove as much residue as possible.
