If a system fault is detected, the system will attempt to recover itself up to five times in a 24 hour period. If unable to recover in that time, the red Call Service LED light will activate. If the TrueSTEAM Call Service light is red, a system fault has occurred from which the humidifier can not recover by itself. The table below shows the possible faults, along with steps to fix TrueSTEAM. If the red Call Service LED light is on, press/release the RESET button. The red Call Service LED light will begin blinking in a series that indicates what fault occurred. Refer to the table below for the fault signified by the number of blinks that occur. Press/hold the RESET button to clear the Service Timer light.
