4. Check all connections to the processor board.
The electronics of the main PCB have diagnosed the main
PCB (itself) as defective.
Reset humidifier and monitor display. If Error reoccurs
within one minute of resetting the unit, the problem is with
the main PCB. If the Error is not repeated, the primary
power to the unit is suspect.
