Display shows E3 during preheating or cooking; unit stops heating.

Safety first: Unplug the multicooker and allow it to cool fully before touching internal surfaces.

• Check pot and contents: Ensure the original Philips inner pot is correctly seated. Verify there is sufficient liquid or food according to the recipe and minimum level markings. Never run the cooker empty.
• Clean heating plate: Remove the inner pot and gently clean the aluminum heating plate with a soft cloth. Remove any burnt-on food or sugar. Do not use sharp tools that can scratch the plate.
• Inspect bottom of inner pot: Check for burnt residue or deformation. Clean thoroughly and replace the pot if the base is warped or heavily scratched.
• Ventilation check: Make sure the cooker is used on a flat, heat-resistant surface with at least several centimeters of clearance around it. Blocked ventilation can cause overheating.
• Persistent E3: If E3 appears even with correct usage and a clean plate, the thermal fuse or overheat sensor on the heater plate may be damaged. Replacement involves opening the base, desoldering or unclipping the thermal fuse, and installing a Philips-compatible part. This should be done by a professional.
