Device Failure Response: Standard Moves When a Device Fails Mid-Treatment

1. Client first: e-stop, check for skin injury, handle per thermal grading if needed.
2. Preserve evidence: don’t rush to reboot — photograph the error screen, parameter page and handpiece state.
3. Isolate: tag the unit out of service to prevent misuse.
4. Recover fast: decide whether a backup device can absorb today’s bookings.

• Model/serial, failure time and treatment phase
• Error codes and photos, parameters and consumable state at the time
• Recent service and parts history
• Any personal injury (if yes, open the adverse-event flow too)

Complete information raises remote-fix rates and first-visit repair rates — that’s why “remote resolution rate” matters in service evaluation.

Can a repaired device return straight to service?

After safety-grade (C) failures, re-verify calibration and run acceptance before serving clients; functional failures follow the vendor’s recheck advice.

How to reduce downtime damage?

• Run preventive maintenance on schedule (the interval table).
• Keep alternative capacity for core programs (a second unit or partner-clinic mutual aid).

• Thermal Grading
• Maintenance
• Adverse Events
