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.
Centrifuge speed / bowl seating error
HighSymptoms: Bowl vibration or noise, speed error, wash aborts.
Root cause: Bowl not seated in the chuck, worn centrifuge chuck, or an out-of-balance bowl set.
Optical line-sensor misreads (fill / hematocrit)
HighSymptoms: Bowl over- or under-fills, wash starts early or late, poor product hematocrit.
Root cause: Dirty or failed optical sensor at the bowl, or air in the line.
Peristaltic pump / valve fault
MediumSymptoms: Flow error, occlusion alarm, pump will not seat the tubing.
Root cause: Worn pump rollers/door or a valve-actuator fault.
Vacuum / wall-suction regulation fault
MediumSymptoms: Reservoir vacuum too high or low, poor collection.
Root cause: Vacuum regulator or a leak in the suction line.

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: Centrifuge speed error / bowl noise
- Stop and confirm the bowl is fully seated and the retainer is closed.
- Inspect the chuck and latch for wear.
- Load a fresh bowl set and re-test.
- Reset the system; if it recurs, contact technical service.
- Verify a clean spin-up before clinical use.
Symptom: Bowl over/under-fills or poor hematocrit
- Clean the optical sensor window at the bowl.
- Check for air in the lines and re-prime.
- Confirm the correct protocol and bowl size.
- Replace the optical sensor if it still misreads.
- Run a saline test cycle and confirm correct fill and wash.
