Error codes
| Code | Meaning | Trigger | Severity |
|---|---|---|---|
Bas Sen Err | Basin sensor error - the basin level sensor has detected a problem | Detected during basin fill or drainage monitoring | error |
Flow Sen Err | Flow sensor error - the water flow sensor is not functioning correctly | Detected during initial start | error |
Lid Ajar | Reprocessor lid is open - safety interlock detected open lid during operation | Detected during initial start | warning |
Low Chamber | Chamber pressure low - insufficient pressure in the disinfectant or rinse chamber | Detected during disinfectant phase or disinfectant/rinse phases | error |
No Air Flow | No air flow detected - compressed air system is not functioning | Detected when air flow is needed for operation | error |
No Fluid FI2 | No fluid flow indicator 2 - fluid flow failure in secondary circuit or drain path | Detected during disinfection or drainage phases | error |
No Fluid Flow | No fluid flow detected - water or disinfectant is not flowing as expected | Detected during disinfect, flush, or rinse phases | error |
