Multicooker displays E1 and refuses to start or aborts cooking shortly after starting.

Safety first: Unplug the cooker and allow it to cool completely before opening any panels.

Basic checks:

• Remove and inspect the inner pot: Ensure the bottom of the pot and the central contact area are clean and dry. Wipe away any burnt residue or moisture.
• Check for deformation: A heavily warped or dented inner pot can cause poor contact and abnormal sensor readings. Try another compatible T-fal inner pot if available.

Sensor inspection (advanced):

• Turn the unit upside down (unplugged) and remove the bottom cover screws.
• Locate the NTC sensor mounted near the center of the heating plate or clamped to it. It is usually a small metal probe or disc with two wires.
• Check that the sensor is firmly attached to the heating plate and not hanging loose.
• Inspect the wiring harness from the sensor to the main control board for burns, cuts, or loose connectors. Reseat the plug on the PCB.
• Use a multimeter to measure the sensor resistance at room temperature (typically 50–150 kΩ depending on model). If it reads open circuit or near 0 Ω, replace the sensor.

Reassembly: After any checks or replacement, reassemble the base, ensuring no wires are pinched, then test with a small amount of water in the pot.
