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.
Not producing humidity / output low
HighSymptoms: Dry gas to the patient, low or no mist, chamber not warming.
Root cause: Heater element or sensor fault, chamber not seated, or a water-level / feed fault.
Over-temperature alarm / shutdown
MediumSymptoms: High-temperature alarm, heater cuts out.
Root cause: Sensor or control fault, or a chamber run dry.
Water chamber / auto-feed fault
MediumSymptoms: Chamber runs dry or overfills, water-out alarm.
Root cause: Float valve or auto-feed fault, or a cracked chamber.
Heater-wire circuit fault (heated circuit)
MediumSymptoms: Rain-out in the tube, heater-wire alarm.
Root cause: Open heated breathing circuit or a heater-wire adapter fault.

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: Low or no humidity
- Confirm the chamber is seated and has water.
- Check the temperature probes and connectors; swap in a known-good set.
- Confirm the heater draws current.
- Check the heated breathing circuit and adapter.
- Replace the heater base plate if it will not heat.
Symptom: Over-temperature alarm
- Confirm the chamber is not dry.
- Compare the displayed temperature to an independent probe.
- Replace the temperature sensor if it disagrees.
- Power-cycle and retry.
- Refer for service if the heater runs away with a good sensor.
