Detergent is not being mixed properly; carpets are either too soapy or not cleaned well despite correct settings.

Safety first: Unplug the unit and remove the detergent tank.

• 1. Verify detergent type and ratio: Use only Beko-approved carpet cleaning detergent and follow the dilution instructions in the manual.
• 2. Clean dosing valve: Inspect the detergent outlet and any mixing valve for dried detergent. Soak in warm water and clean thoroughly.
• 3. Check siphon tube: Ensure the internal tube in the detergent tank is intact and reaches the bottom. Replace the tank if the tube is damaged.
• 4. Inspect cap and inserts: Some tanks use special caps or inserts to control flow. Make sure they are present and correctly installed.
