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 / abort
HighSymptoms: Cycle stops with a fault code, load not processed, door locked.
Root cause: Water fill / drain fault, temperature not reached, a dosing-pump fault, or a spray-arm blockage.
Poor cleaning / spray-arm blockage
MediumSymptoms: Instruments come out soiled, spray arms not rotating.
Root cause: Clogged spray-arm nozzles, a blocked filter / strainer, or low water pressure.
Chemistry dosing fault
MediumSymptoms: Detergent / lubricant not dosed, dosing-pump alarm.
Root cause: Empty chemistry container, an air-locked or worn peristaltic dosing pump, or a level sensor.
Temperature not reached / thermal-disinfection fail
HighSymptoms: A0 / disinfection temperature not achieved, cycle fails validation.
Root cause: Heater element, temperature sensor, or steam-supply fault.
Door / seal fault
MediumSymptoms: Leaks during the cycle, door will not lock or unlock.
Root cause: Worn door gasket or a door-lock solenoid.

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 / abort
- Note the fault code and the phase it aborted in.
- Check the water fill and drain, and the chamber filter / strainer.
- Confirm the spray arms rotate freely and the nozzles are clear.
- Verify the heater reaches temperature and the sensor agrees with a reference.
- Follow the STERIS service manual for the specific code.
Symptom: Instruments still soiled
- Clear the spray-arm nozzles and check the arms spin.
- Clean the chamber filter / strainer.
- Confirm detergent is dosing (container level, dosing pump primed).
- Check the water pressure and temperature.
- Run a soil / protein test on the next cycle.
