1. Purpose
To outline the systematic procedure for troubleshooting technical and operational issues encountered with vial and syringe filling machines used in sterile injectable manufacturing, ensuring minimal downtime and maintenance of aseptic conditions.
2. Scope
This SOP applies to all production, maintenance, and
QA personnel involved in the operation, inspection, and support of filling machines in the aseptic manufacturing areas.
3. Responsibilities
- Machine Operator: Identifies and reports issues, performs basic troubleshooting.
- Engineering Technician: Investigates and resolves mechanical/electrical issues.
- Production Supervisor: Approves restart after resolution and ensures documentation.
- QA Officer: Reviews troubleshooting logs and verifies compliance.
4. Accountability
The Head of Production is accountable for implementation of troubleshooting protocols and minimizing machine downtime through adherence to this SOP.
5. Procedure
5.1 Identification of Issue
- Monitor visual and audible alarms from the filling machine HMI (Human Machine Interface).
- Pause the operation using emergency stop or pause switch.
- Record the fault code/error message in Annexure-1: Issue Log Sheet.
5.2 Common Troubleshooting Scenarios
- Filling Volume Inaccuracy
- Check calibration of dosing system.
- Inspect pistons or peristaltic tubing for leaks or wear.
- Verify container alignment under nozzles.
- Vial Misalignment or Jamming
- Check conveyor speed and positioning guides.
- Remove jammed vials using sterile forceps (if within aseptic area).
- Nozzle Dripping or Blockage
- Clean nozzle tip using sterile wipes.
- Check actuator mechanism and air pressure.
- Machine Stoppage or Alarm without Obvious Cause
- Review HMI alarm history log.
- Reset the system only after QA verification.

5.3 Root Cause Identification
- Use fishbone diagram or 5-Why analysis for recurring faults.
- Document root cause analysis in Annexure-2.
5.4 Corrective Actions
- Replace worn-out parts with validated spares.
- Recalibrate dosing systems after fixing volume errors.
- Apply lubrication to mechanical joints (if permitted in cleanroom).
5.5 Preventive Actions
- Update preventive maintenance schedule if required.
- Train staff on identified causes and correct handling practices.
5.6 Restart and Documentation
- Perform visual verification of the fix and sanitize area if required.
- Enter corrective action taken in Annexure-3: Corrective Action Log.
- QA to review logs before machine restart.
