Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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.
Result / QC failure
HighSymptoms: Strip results flagged or biased, QC out of range, colour blocks misread.
Root cause: Expired or mishandled strips, a dirty / aged optics head, or a calibration issue.
Strip transport / feed fault
MediumSymptoms: Strip not transported, jams, or read at the wrong position.
Root cause: Worn strip-transport belt / tray or a position-sensor fault.
Optics / reflectance-head fault
MediumSymptoms: Repeated optics errors, non-uniform reads across the pads.
Root cause: Contaminated or aged reflectance LEDs / optics.
Sediment / microscopy module fault (if fitted)
MediumSymptoms: Poor particle images, flow-cell or camera errors.
Root cause: Flow-cell contamination, a pump fault, or the camera / focus.
Printer / LIS fault
LowSymptoms: No printout, results not sent to the LIS.
Root cause: Printer or the interface configuration.

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.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
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: QC / calibration failure across a channel or the whole system
- Run fresh controls at all levels and note which analytes fail.
- Confirm reagents are in date, correctly loaded, mixed and not bubbled.
- Run the photometer / lamp-energy check and replace the lamp if energy is low.
- Clean the sample and reagent probes, the mixers and the wash / cuvette-wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Sample or reagent probe clog / crash / short aspiration
- Inspect the probe for a bend or blockage and clear it (wire / sonicate per the manual).
- Run the fluidics prime and the probe-wash cycle.
- Check for a clot or fibrin in the sample and the liquid-level sensing.
- Verify probe positioning / alignment.
- Replace the probe if aspiration is still short.
Symptom: ISE electrolyte results biased or noisy / ISE calibration fails
- Run the ISE calibration and check the slope / drift against spec.
- Replace an ISE electrode or the reference that is at end of life.
- Check the ISE pinch valves and tubing for wear or air.
- Confirm the ISE standard packs are in date.
- Re-run ISE QC before releasing electrolyte results.
Symptom: High cuvette blanks / position-dependent results
- Run the cuvette blank / photometric check.
- Clean or replace worn / scratched cuvettes or the reaction segment.
- Check the cuvette-wash station nozzles and drying.
- Confirm the water / DI supply quality.
- Recalibrate and re-run QC.
