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.
Low or no suction / capture
HighSymptoms: Plume not captured, weak airflow, blower ramps but flow is low.
Root cause: Loaded ULPA / charcoal filter, a worn blower / turbine, or a leak / kink in the hose.
Filter loaded / end of life
MediumSymptoms: Filter-change alarm, reduced airflow, odour breakthrough.
Root cause: ULPA / activated-charcoal filter at end of its capacity.
Auto-activation / ESU-sync fault
MediumSymptoms: Evacuator does not start with the ESU, or runs continuously.
Root cause: The ESU-sensing cuff / cable or the auto-activation board.
Blower / turbine fault
MediumSymptoms: Noisy, weak, or dead blower even with a new filter.
Root cause: Worn blower / turbine bearings or motor.
Noise / control fault
LowSymptoms: Very loud in use, speed will not adjust.
Root cause: Worn blower or a speed-control fault.

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: Low or no capture
- Fit a fresh filter and confirm the change alarm clears.
- Check the hose and wand for kinks or blockage.
- Confirm the blower spins up to full speed.
- Measure capture at the wand if a meter is available.
- Replace the blower / turbine if flow is low with a new filter.
Symptom: Does not auto-start with the ESU
- Confirm auto-activation mode is selected.
- Check the ESU-sensing cuff is around the correct ESU lead and the cable is intact.
- Test manual mode to confirm the blower works.
- Adjust the activation sensitivity if provided.
- Replace the sensing cuff / auto-activation board as isolated.
