Display shows 'burn' and cooker stops heating; food is likely scorched on bottom.

Safety first: Unplug the cooker and allow pressure to release naturally if under pressure.

• Open and inspect: Once safe, open the lid and check for scorching on the bottom of the inner pot.
• Remove burnt food: Transfer salvageable food to another container, then soak and scrub the inner pot to remove all burnt residue.
• Clean heating plate: Wipe the heating plate and sensor area clean and dry.
• Modify cooking method: Add more liquid, avoid stirring thick sauces to the bottom, and consider using the Pot-in-Pot method for very thick dishes.
• Test with water: Run a short water-only cycle to confirm the cooker operates normally. If 'burn' appears even with water, inspect the bottom temperature sensor and inner pot for damage.
