Possible Causes

Overheating causing thermal cut-out to trip, Loose mains connection inside machine, Failing power switch, Faulty main PCB

How to Fix / Troubleshooting

Safety first: Unplug the machine before inspection.

Steps:

  • Ventilation: Ensure the machine has adequate space around it for cooling and is not enclosed in a cabinet.
  • Check cable and plug: Wiggle the cable gently (while unplugged) and inspect for damage.
  • Internal connections (advanced): Open the housing and check that all mains connectors and spade terminals are tight.

Note: If the machine is very hot when it shuts off, the thermal cut-out may be operating correctly due to another fault such as scale or a failing fan.
