Float

If the reservoir overfills the float assembly is not working properly. The float assembly has an integrated seal, when the water enters the reservoir the float bulb goes up and presses against the seal to stop the flow of water. If the seal is dried out or gone, or if the float bulb is jammed or obstructed, it may not shut off the water when the reservoir is full and then the reservoir overfills. Try adjusting the float assembly. If this is unsuccessful, replace the entire float assembly.

Water Inlet Valve

If the reservoir overfills the water inlet valve might not be shutting off properly. Once the humidity in the home reaches the proper level, the humidistat should turn off, cutting power to the water inlet valve. If the humidistat does cut power but the valve still doesn't shut off, the valve might be stuck or jammed open. Test this by disconnecting power to the humidifier and see if water still flows through the valve. If it does, replace the water inlet valve, they're not repairable.
