Carpet cleaner leaves detergent residue or white marks on carpet

Safety: Unplug before changing settings or cleaning components.

• Adjust detergent mix: Dilute detergent according to Siemens instructions. Do not exceed recommended concentration.
• Rinse cycle: Run several passes with clean water only (no detergent) to remove residue from carpet.
• Check dosing valve: Ensure the detergent valve closes fully when not in use. Clean or replace if it leaks detergent continuously.

Proper dosing and thorough rinsing will prevent visible residue.
