Machine shuts off unexpectedly during use and may restart after cooling.

Safety: Unplug the machine and allow it to cool before inspection.

• Check ventilation: Ensure there is adequate space around the machine for airflow and that vents are not blocked by walls or other equipment.
• Inspect for heat damage: Look for discolored wiring or connectors near high‑current components (heaters, pump).
• Test pump and heaters: A failing pump or partially shorted heater can draw excessive current. Measure current draw if you have appropriate tools, or have a technician test.
• Secure connections: Tighten all mains and high‑current terminal screws to reduce resistive heating.
