Key tips
- ·Conductivity and water-quality checks are non-negotiable before every shift - dialysate chemistry errors are a direct patient-harm mechanism.
- ·Confirm disinfection cycle completion, never assume it, after every use.
- ·Treat a blood-leak detector fault as real until proven otherwise - never silence and continue.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Conductivity / dialysate fault
HighSymptoms: Conductivity out of range, dialysate alarm.
Root cause: Mixing valve or sensor fault.
Blood pump occlusion / wear
MediumSymptoms: Flow error, roller wear alarm.
Root cause: Pump segment fatigue.
Ultrafiltration error
MediumSymptoms: UF inaccuracy, weight alarm.
Root cause: Balance system / scale fault.
Heparin pump fault
LowSymptoms: No infusion, air alarm.
Root cause: Occlusion or drive failure.

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.
- ·Disinfection cycle verification
- ·Conductivity and water-quality check
- ·Blood-leak detector test
- ·Scheduled tubing / filter replacement
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Blood leak detector false/real
- Confirm the presentation - typically blood leak alarm, treatment stop - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: optical cell dirty or true leak.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the blood tubing set / roller segment per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
