ASP Sterrad 100S
ASP · Model Sterrad 100S
Endorsed by leading Medical Device Manufacturers on their IFUs. Sterilizes a wide range of instruments, including da Vinci® 3-D endoscopes*. One button operation makes it easy to use.
Key tips
- ·A failed biological indicator means the entire load is not sterile - no exceptions, regardless of how the cycle printout looks.
- ·Door gasket wear is the most common real cause of a failed vacuum/pressure test - check it before deeper diagnostics.
- ·Water quality directly affects steam-cycle validity - don't ignore scale or mineral buildup.
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.
Cycle abort / cancelled cycle
HighSymptoms: Cycle cancels with a fault code, load not sterile, must be re-run.
Root cause: Insufficient vacuum, a load / packaging that absorbs peroxide, a peroxide-cassette / injection fault, or a plasma-generation (RF electrode) fault.
Vacuum will not be achieved
HighSymptoms: Vacuum-fault alarm, long pump-down, cycle aborts.
Root cause: Vacuum-pump wear (low oil / worn vanes on older D16 pumps), a chamber-door seal leak, or a valve fault.
Peroxide monitoring / concentration fault
MediumSymptoms: Low-concentration or monitor alarm, cassette not read.
Root cause: Expired or empty peroxide cassette, a cassette-reader fault, or a peroxide-monitor sensor.
Vaporizer / injection fault
MediumSymptoms: Peroxide not vaporised or injected correctly, cycle fault.
Root cause: Vaporizer plate contamination or a heater / valve fault.
Printer / display fault
LowSymptoms: No cycle printout, unresponsive display.
Root cause: Printer or display fault.

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 biological and chemical indicator test loads
- ·Door gasket / seal inspection
- ·Steam trap and drain strainer cleaning
- ·Annual full PM and pressure-vessel certification
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: Cycle abort / cancelled cycle
- Note the fault code and the phase it aborted in.
- Confirm the load is dry, non-absorbent and correctly packaged for STERRAD.
- Fit a fresh, in-date peroxide cassette and confirm the reader accepts it.
- Check the vacuum pump (oil level / condition on D16 pumps) and the door seal.
- Clean the vaporizer plate; follow the ASP service guide for the specific code and the current PM level.
Symptom: Vacuum will not be achieved
- Inspect the chamber door seal for damage.
- Check the vacuum-pump oil and change it / the filter per the PM schedule.
- Listen for a valve not sequencing.
- Run a leak / vacuum-decay test.
- Rebuild or replace the pump if vacuum is still weak with a good seal.
