Troubleshooting
SC No. Level Error Name/Error Condition/Major Cause/Solution
542-04 B Reload failure: Low voltage and thermistor deformation
An error is detected only when the input voltage at power-on is
low.
The temperature of 7°C or lower is detected five times
consecutively for 3 seconds.
 Measurement begins 15 seconds after the heater is turned
on.
 Measurement interval: 0.1 sec.
 If the reload temperature is reached during measuring, the
measurement is cancelled.
 Thermistor deformed
 Thermistor out of position
 Out of guaranteed input voltage
 After over-heat prevention
 Replace the thermistor (center).

542-06 B Reload failure: Low voltage and heater deformation
An error is detected only when the input voltage at power-on is
low.
 Normal (no pre-rotation):
The reload temperature is not reached for 90 seconds after
heater control starts.
 Pre-rotation:
The reload temperature is not reached for 285 seconds after
heater control starts.
 Heater damaged
 After over-heat prevention
 Replace the heater.
