Multicooker takes much longer than usual to cook the same recipe.

Safety first: Unplug and cool before cleaning or internal checks.

• Clean heater and pot: Remove any scale or residue from the heater plate and inner pot bottom.
• Check power source: Use a dedicated outlet and avoid extension cords that may cause voltage drop.
• Compare with water test: Time how long it takes to bring a known volume of water to boil. If significantly slower than manual specs, the heater or sensor may be failing.
• Service if needed: Persistent slow heating indicates a likely heater or control issue requiring professional diagnosis.
