What to do if my Pure Humidifier will not fill?
- DDanielle ThomasAug 10, 2025
If your Pure Humidifier isn't filling, start by checking the water supply to ensure there's adequate water pressure. If pressure is present, inspect the fill valve to see if it's stuck open and check for 24 VAC across the solenoid valve. Also, verify if there is power to the fill valve by checking for 24 VAC across the solenoid valve; if there's no voltage, look for dirt under the valve seat. Finally, make sure the drain valve is closed, and if you're using an auto-drain system, confirm the manual drain lever on the front of the drain valve is closed.
