Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Wax not melting or temperature not held
HighSymptoms: Wax reservoir or dispenser not at working temperature, wax solidifying.
Root cause: Heater element, temperature sensor, or control-board fault.
Wax dispenser will not dispense or drips
MediumSymptoms: No flow from the dispenser, or a continuous drip.
Root cause: Clogged or worn wax dispenser valve / nozzle.
Cold plate / cryo module not cooling
MediumSymptoms: Cold plate not cold, blocks will not set.
Root cause: Thermoelectric (Peltier) module or its fan / control fault.
Fuses blow repeatedly
MediumSymptoms: Unit dead, replacement fuses fail again.
Root cause: A downstream short - disconnect and contact service.
Heated forceps / work-surface zone fault
LowSymptoms: A heated zone or the forceps does not warm.
Root cause: Zone heater or the forceps element / connector.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Wax not at temperature
- Check the set temperatures for each zone.
- Confirm the heater draws current and the element is intact.
- Compare the sensor reading to an independent probe.
- Replace the sensor or element as found.
- Verify each zone reaches and holds temperature.
Symptom: Fuses blow repeatedly
- Ensure the unit is off and disconnected from mains.
- Fit correctly rated fuses as a pair.
- If they blow again, stop replacing them.
- Disconnect and contact service.
- Do not return to use until the short is found.
