Disinfection of condensate available as an option. Possibility to program up to 8 additional cycles following customer needs.
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 fault / will not reach sterilization parameters
HighSymptoms: Cycle aborts, temperature or pressure not reached / held, failed BI or chemical indicator.
Root cause: Heater / element fault, a door-gasket leak, a steam-generation or water-fill fault, a blocked chamber drain / strainer, or a temperature / pressure-sensor fault.
Door / gasket seal fault
MediumSymptoms: Steam leak at the door, door will not seal, lock or unlock, pressure will not build.
Root cause: Worn door gasket or a door-lock / interlock fault.
Poor drying / wet packs
MediumSymptoms: Instruments / packs come out wet.
Root cause: Drying-phase vacuum / heater fault, an overloaded chamber, or a clogged drain.
Water / reservoir / feedwater fault
MediumSymptoms: Low-water alarm, mineral scale, cloudy chamber, poor steam quality.
Root cause: Empty or scaled reservoir, a fill-valve / pump fault, or use of non-distilled water.
Steam-trap / air-removal / vacuum fault
MediumSymptoms: Failed Bowie-Dick / air-removal test, slow come-up, air pockets.
Root cause: Blocked steam trap, a vacuum-pump / ejector fault, or a check-valve fault.
Printer / recorder fault
LowSymptoms: No or faint cycle printout.
Root cause: Thermal print head or paper.

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 fault or parameters not reached
- Note the fault code and the phase it aborted in.
- Confirm the reservoir has distilled water and the fill / feedwater path and strainer are clear.
- Inspect the door gasket for a leak and the door lock / interlock.
- Compare the displayed temperature / pressure to independent references.
- Replace the gasket, element or sensor as isolated, then run a BI and a leak / Bowie-Dick test.
Symptom: Wet packs / poor drying
- Reduce the load and re-space so steam and air can move.
- Check the drying-phase vacuum and heater.
- Clean the chamber drain / strainer.
- Confirm packaging is drying-compatible.
- Re-run and inspect for dryness.
