E8 error appears during pressure cooking; unit may not reach or maintain pressure.

Safety first: Unplug the cooker and ensure it is fully depressurized before opening the lid or accessing internal components.

Steps to address E8:

• 1. Confirm proper sealing: Before assuming a sensor fault, verify that the sealing ring, lid, and valves are clean and correctly installed. Poor sealing can cause abnormal pressure readings.
• 2. Locate the pressure sensor: On many Steba models, the pressure sensor is mounted either under the lid or inside the top housing, connected to the steam chamber via a small tube or channel.
• 3. Inspect and clean sensor port: If accessible, gently clean the sensor port or tube with a soft brush and a damp cloth. Do not insert sharp objects into the sensor opening.
• 4. Check wiring and connector: With the top cover removed (model-dependent), locate the pressure sensor module and ensure its connector is firmly seated on the PCB. Inspect the harness for kinks or damage.
• 5. Replace pressure sensor if faulty: If E8 persists and other pressure components are known good, replace the pressure sensor module with a compatible Steba part. Transfer any sealing gaskets or mounting brackets from the old sensor.
• 6. Test with water-only pressure cycle: After reassembly, run a short pressure program with water only to verify that the cooker reaches and maintains pressure without E8.

Important: Incorrect handling of the pressure sensor or its seals can lead to unsafe pressure operation. If unsure, use an authorized service center.
