Detergent not mixing correctly, either too strong or no detergent in spray

Safety: Unplug the unit and remove the detergent container or cartridge.

• Verify detergent type: Use only Kobold-approved carpet cleaning detergent designed for your model.
• Clean siphon tube: Rinse the detergent pickup tube and check for blockages or hardened residue.
• Check cartridge seating: Ensure any detergent cartridge clicks fully into place and its piercings are clear.
• Flush system: Run a tank of clean water through the system to clear old detergent before retesting.
