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.
Aperture blockage / partial obstruction
HighSymptoms: Flagged or implausible CBC counts, voteouts, aperture-clog alarms, poor precision.
Root cause: Debris or a clot partially blocking a counting aperture.
Sample probe / piercer / valve wear
MediumSymptoms: Short samples, aspiration errors, cap-piercing failures, carryover.
Root cause: Worn or bent sample probe / closed-vial piercer, or a worn segment / shear valve.
Reagent / lyse delivery fault
MediumSymptoms: WBC, HGB or diff results shifted, high background, reagent alarms.
Root cause: Reagent depleted or wrong lot, or a pinch-valve / tubing fault.
VCS / flow-cell / laser fault (diff)
MediumSymptoms: Diff scattergrams abnormal, missing populations, flow-cell or laser alarm.
Root cause: Contaminated or aged flow cell, or the laser / optics.
Autoloader / transport jam (DxH)
MediumSymptoms: Tubes not advancing, cassette / carousel error, mixing-station fault.
Root cause: Worn autoloader belt / gripper, a mis-loaded rack, or a mixing-station fault.
Vacuum / pressure out of range
MediumSymptoms: Multiple parameter errors, priming failures.
Root cause: Pump or regulator drift.

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: Aperture-clog alarm / flagged counts
- Run the instrument's aperture-clear / burn and flush cycles.
- Run a background count and confirm it is within limits.
- Run controls at all levels.
- Clean or replace the aperture bath if clogs recur.
- Confirm precision on a replicate sample before releasing results.
Symptom: Short samples / aspiration errors
- Inspect the sample probe / piercer for wear or a bend.
- Check the segment / shear valve and tubing for leaks or wear.
- Verify vacuum and pressure against the service spec.
- Replace the probe / piercer, valve or tubing as found.
- Re-run controls.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The recall was initiated because Beckman Coulter has confirmed that an issue has been identified with one of the raw materials used to manufacture the Coulter A T 5 diff PN 8547171.
- RECALL
The recall was initiated because Beckman Coulter identified a problem with occasional unexpectedly high results for RBC, HCT, PLT and MPV without instrument generated messages, for the first run of a capped patient sample. Upon repeat analysis the results are correct. Patients could be affected as described below: (1) False high RBC and HCT may result in a delay of treatment, or the delivery of
- RECALL
Software anomaly causes sample results to be not credible, reported as '0' or left blank. The next sample will also be incorrectly reported for the same parameter.
- RECALL
Samples with high fat content will not count platelets accurately.
