- Strange noises or smells. Grinding, clicking or a burning smell mean something is wearing or overheating. Stop and report it.
- Error codes that keep coming back. Restarting the machine is not a repair. Write the code down and tell the technician.
- Alarms that won’t clear. Never silence an alarm and carry on. Alarms protect patients.
- Running hot. Overheating shortens a machine’s life. Check that vents are clear and the room is not too hot.
- The service date has passed. Check the service sticker on the machine. If it’s overdue, book a service.
Remember: small faults become big repairs. Reporting early usually means one small part and one short visit.
