Detergent is not being mixed into the solution; only plain water appears to be sprayed.

Safety first: Unplug the unit and avoid spilling concentrated detergent on skin or eyes.

• Check detergent level: Ensure the detergent tank is filled and properly seated.
• Inspect siphon tube: Remove the detergent tank and check the pickup tube for blockages or kinks. Rinse with warm water.
• Clean metering valve: Access the detergent valve and flush it with warm water to remove dried detergent.
• Test with colored water: Fill the detergent tank with a small amount of colored water and observe if it is drawn into the solution line during operation. If not, replace the metering valve or hose.
