Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
Blood leak detector (BLD) calibration fault
HighSymptoms: BLD AD/steps too low (<250), zero, or too high (>800) during calibration; false blood-leak alarms.
Root cause: Scratched detection chamber, dirty or wrongly-inserted mirror (silver spot up), LED/sensor misalignment, BLD-module potentiometer out of adjustment, or a failed BLD module / Master CPU.
Peristaltic pump fault (one of four)
HighSymptoms: Flow error on blood, dialysate, filtrate or substitution pump; occlusion or pressure alarm; inaccurate fluid balance.
Root cause: Worn pump rollers/race, a pump-door / occlusion sensor fault, or a motor/encoder fault.
Scale / fluid-balance fault
HighSymptoms: Fluid-balance alarm, implausible filtration or substitution volume, treatment stops on balance error.
Root cause: One of the two weighing scales / load cells out of calibration or mechanically bound.
Pressure-transducer fault
MediumSymptoms: Access, return, filter or effluent pressure reads wrong; frequent pressure alarms.
Root cause: One of the four pressure transducers drifted or a protector wetted.
Substitution-fluid heater / degassing fault
MediumSymptoms: Return fluid too cool or warm, temperature alarm, air detected at the degassing chamber.
Root cause: Heater element, temperature sensor at the degassing chamber, or a degassing fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
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: BLD calibration AD/steps zero or too low
- Check the red LED on the BLD - if it is not flashing, exchange the BLD module (BG-E431); if still not flashing, exchange the Master CPU (BG-E425).
- For low steps (<250): fit a new unscratched detection chamber (scratches scatter the light).
- Clean the mirror and insert it with the silver spot on top (dirt reduces reflected light).
- Adjust the BLD-module potentiometer, then adjust the LED and sensor so both focus on the centre of the mirror.
- For high steps (>800): re-check the mirror orientation, then re-run calibration.
Symptom: Fluid-balance alarm / implausible volumes
- Remove any load and check both scales read zero and are free to move.
- Hang a known reference weight and confirm each scale reads correctly.
- Inspect the scale mounts for binding or debris.
- Recalibrate the scales per the service manual.
- Run a priming / self-test cycle and confirm balance tracks correctly before clinical use.
