Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
No power to control panel	Circuit breaker tripped	Check main power supply; reset breakers; verify voltage.
Water flow alarm	Low water pressure/flow	Check water supply; inspect for blockages; verify pump operation.
Over-temperature shutdown	Cooling system failure	Check water temperature; verify flow rate; inspect heat exchanger.
Poor melting efficiency	Refractory wear	Inspect refractory lining; replace if necessary; check coil condition.
Control system errors	Sensor failure	Check thermocouples; verify wiring; recalibrate sensors.

Reset Procedure: Control Panel > System > Reset after addressing root cause.
