Thermomix base becomes unusually hot to the touch on the underside or sides during normal operation.

Safety first: If the base feels very hot, stop the program, unplug the unit, and allow it to cool.

• Improve ventilation: Ensure the appliance has sufficient clearance on all sides and is not enclosed in a tight space.
• Clean vents: Use a soft brush or vacuum to clear dust from all external vents.
• Limit duty cycle: Avoid running multiple long, high-temperature programs back-to-back. Allow cooling periods.
• Service if persistent: If the base continues to overheat, the internal fan or thermal management system may be failing and should be inspected by a technician.
