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.
Distension pressure not maintained
HighSymptoms: Set pressure sags or overshoots, poor distension, pressure alarms.
Root cause: Inflow pump rollers, a pressure-sensor fault, or a tubing-set fault.
Fluid not warming to target
MediumSymptoms: Return fluid cool, warming not reaching up to 40 C.
Root cause: Heater cartridge or its temperature control.
Fluid deficit inaccurate / deficit alarm fault
HighSymptoms: Deficit reads implausibly or will not tare; alarm at the wrong volume.
Root cause: Weigh scale / load cell out of calibration or bags not hung freely.
Tubing-set / cassette not recognised
MediumSymptoms: System will not prime or recognise the disposable set.
Root cause: Cassette mis-seated or a set-detect sensor 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: Pressure will not hold
- Fit a fresh tubing set and re-prime.
- Confirm inflow and outflow lines are not kinked or clamped.
- Check the inflow pump rollers for wear.
- Verify the pressure transducer against a reference if tooling allows.
- Replace the pump roller assembly or transducer as found.
Symptom: Deficit reading wrong
- Confirm all inflow and outflow bags hang freely on the scale.
- Tare at rest with no load change.
- Hang a known reference weight and confirm the reading.
- Recalibrate the scale per the service manual.
- Replace the load cell if it will not calibrate.
