• Check that the air cap is fully open.
• If the weather is cold, the inside of the machine may be frozen and spraying may not be possible. Try putting it in a warm room for a few hours before using it
• The strainer connected to the water nipple may be clogged. Submerge the strainer in chemicals you would typically use to clean the toilet or kitchen drain. Let it sit for 1 hour then rinse with clean water.
• If you are still unable to spray, replace the check valve.
