The temperature of the steam generator (boiler) has failed to drop below a set point temperature in a timeout period.
Check the water reservoir for water. If the reservoir is empty, check if Float Switch is stuck in the raised position. Tap float with a long instrument, screwdriver, or ruler, so floats drop. Refill the reservoir with water. End User repair
If the float continues to stick, replace the Float Switch in reservoir part #01-110891S. Field Service Tech. repair
Check the pump using the Pump Tester Bottle. Field Service Tech. repair
