E15 error, cooker beeps and shows error when trying to start any program

Safety first: Turn off and unplug the cooker. Allow it to cool for at least 30 minutes.

• Improve ventilation: Move the cooker to a well‑ventilated area with at least 10 cm clearance on all sides and above.
• Clean vents: Use a soft brush or vacuum to remove dust and grease from side and bottom ventilation slots.
• Check internal fan: If your Severin model has an internal cooling fan, listen for it when powered on. If it does not run, access the fan and test it with a multimeter; replace if faulty.
• Avoid enclosed spaces: Do not operate the cooker inside cabinets or tight corners.

Warning: Persistent E15 even in a cool, open area may indicate a failing temperature sensor on the PCB; seek professional service.
