Multicooker displays E16 and refuses to start; may occur after the unit has been dropped or impacted.

Safety first: Disconnect power before opening the base. Do not operate the cooker without the inner pot.

Steps to check:

• Confirm correct pot: Use only the original Siemens inner pot. Some models detect the specific pot type and will show E16 with incompatible cookware.
• Seat the pot firmly: Remove and reinsert the pot, rotating slightly to ensure full contact with the heater plate.
• Inspect for deformation: Check the bottom of the pot and the heater plate for dents or warping that could affect sensor readings.
• Access sensor (advanced): Remove the bottom cover to locate the weight or presence sensor assembly under the heater. Ensure it is not bent or dislodged.
• Check wiring and switch: Inspect the sensor wiring harness and any microswitches for damage. Test for continuity when the pot is pressed down.

When to call a technician: If the sensor assembly is damaged or calibration is lost, professional replacement or adjustment is required.
