Safety first: Unplug the Severin multicooker from the mains and allow it to cool completely before opening any covers.

Steps to check and fix:

Inspect the sensor connector: Remove the inner pot and bottom cover (usually Phillips screws). Locate the bottom temperature sensor (NTC) clipped to or near the heating plate. Ensure its 2‑pin connector is firmly seated on the control PCB.
Check for broken wires: Gently tug each wire from the NTC to the board. If any wire feels loose, frayed, or broken, repair with proper crimp connectors or replace the harness.
Measure sensor resistance: With a multimeter set to kΩ, measure across the NTC pins. A typical room‑temperature reading is 50–150 kΩ (varies by model). If the meter shows OL (open) or 0 Ω, the sensor is defective.
Inspect PCB solder joints: Check the NTC connector solder joints on the main board for cracks or cold solder. Reflow with a soldering iron if you are qualified; otherwise, replace the board or contact a technician.
Reassemble and test: Refit the bottom cover, plug in the cooker, and run a short program with water in the pot to confirm the error is cleared.

Warning: Do not bypass or short the sensor; this can cause overheating and fire risk.
