Clean water tank appears full but the machine quickly stops spraying and behaves as if the tank is empty.

Safety: Unplug the unit before handling tanks.

• 1. Inspect cap and gasket: Remove the clean water tank cap and check the rubber gasket. Replace if it is cracked, hardened, or missing.
• 2. Check bottom valve seal: Examine the tank bottom valve for proper seating and cleanliness. Clean any debris and ensure the spring-loaded valve moves freely.
• 3. Reseat tank: Reinstall the tank, pressing down firmly until it locks. A partially seated tank can allow air into the system.
• 4. Look for cracks: Inspect the tank neck and body for cracks that could admit air. Replace the clean water tank if damaged.
• 5. Test spray: After corrections, test spray for at least 30 seconds to confirm consistent flow.
