Display shows E3 and cooking cannot start or stops shortly after starting.

Safety first: Unplug the cooker and allow it to cool. Overheating can damage internal components and pose a burn risk.

• Check inner pot placement: Remove the inner pot and inspect the heating plate. Ensure there is no debris, warped metal, or foreign objects. Reseat the pot firmly so it makes full contact with the plate.
• Verify liquid level: For pressure and slow cook modes, ensure you meet the minimum liquid requirement specified in the Crock-Pot manual (typically at least 1–2 cups). Never operate the cooker dry.
• Inspect for scorching: Look for burnt food stuck to the bottom of the inner pot. Clean thoroughly with non-abrasive tools so heat can distribute evenly.
• Check ventilation: Make sure the cooker is on a hard, flat surface with several inches of clearance on all sides. Do not operate under low cabinets where heat can accumulate.
• Reset and test: After cooling for at least 30 minutes, plug in and try a low-temperature program (e.g., Keep Warm). If E3 appears immediately, there may be a sensor or thermal fuse issue.
• Internal inspection (advanced): With the unit unplugged, remove the bottom cover. Inspect the thermal fuse and over-temperature sensor mounted near the heating plate. Look for discoloration or burn marks.
• When to replace: If the thermal fuse is open or the over-temp sensor is visibly damaged, replace the thermal fuse / over-temperature sensor assembly. If you are not comfortable testing these components, contact a qualified technician.
