My central vacuum starts but stops after a short time – what could be the cause?
When the central vacuum starts and stops after a short time, this is often caused by partial or complete blockages in the ducting or hose. This restricts airflow, which can cause the motor to overheat. To protect the motor, the overheating protection will activate and shut down the vacuum. Check the hose and ducting for blockages and ensure free airflow before using the vacuum again.
