Programs that require heating take much longer than expected to reach temperature, or never reach set temperature.

Safety first: Unplug and allow the appliance to cool before cleaning or inspection.

• Clean bowl bottom: Thoroughly clean the outside bottom of the bowl to remove burnt-on residue or scale that can insulate heat transfer.
• Check bowl seating: Ensure the bowl is fully seated and locked into the base so it contacts the heater block properly.
• Test with water: Heat a measured amount of water from room temperature to a set temperature and time how long it takes. Compare with normal performance.
• Service if slow: If heating remains significantly slower than normal, the heater or temperature sensor may be partially failing and should be tested and replaced by a technician.
