Common solutions for: Humidifier not getting water

01 - Clogged Saddle Valve

The saddle valve is a small brass water supply valve which is often clamped to a copper household water supply pipe. Over time, the saddle valve can become clogged with sediment or calcium deposits. Because it is difficult to clean a saddle valve thoroughly, and because the replacement cost is fairly low, we recommend replacing the saddle valve if it is restricted.

02 - Humidistat

If the humidistat is incorrectly set or isn't working properly, the humidifier won't fill with water. To determine if the humidistat is defective, turn the humidistat to the highest setting and listen for a "click." If you do not hear a click, this indicates that the electrical contacts inside the humidistat are not closing. If you do hear a click, but the humidifier still won't fill with water, it is more likely that another part is defective.

Highly Likely

03 - Float

A drum style humidifier will use a float to regulate the amount of water entering the humidifier. When the tray fills with water to a certain point, the float will rise up and shut off the water inlet valve. A damaged float may not allow the inlet valve to open at all, resulting in the humidifier not getting any water. Inspect the float to determine if it is obstructed or damaged and replace if necessary.

Less Common

04 - Water supply valve turned off

Confirm the water supply shut off valve is in the on position. You may have to rotate or pull a knob or move a lever to open and shut the valve. You can follow the water line from the humidifier's water inlet valve to find the water supply valve.

Less Common

05 - Humidistat turned off or not set properly

If your humidifier is not getting water, verify that the humidistat is on and set properly. If there is a on/off switch, make sure it's turned on. A normal comfortable humidity range in a home is between 40% to 50%. Refer to owner's manual for guidance.

Uncommon But Possible

06 - Water Supply Problem

If the humidistat is set properly, the humidifier is turning on when the furnace runs, and the water supply valve is on, but not water is reaching the water inlet valve, then there may be a water supply issue.

Uncommon But Possible

07 - Normal Operation

The humidifier only lets water in when the furnace is on. If water is trickling through the evaporator pad when the furnace is running and the humidistat is on, this is normal operation.
