GE Profile GEOSPRING Smart (PF / PH, 2025 on) error code H20
alert
What it means
Water leak notification: the leak sensor detects a water leak; an audible alert sounds and a notification is sent via SmartHQ (if connected). If a smart water shut-off valve is installed, display toggles between "Off" and "H20" and new water supply is stopped.
What GE says to do
To clear the leak alert, remove the sensor from the leak source and dry sensor. The display will stop showing "H20" and "Off" and the valve will open, restoring water flow.
