What does Smeg E08 mean?
Smeg shows E08 as a probe fault. The display title reads "PROBE FAULT" with the description "OVEN CHAMBER PROBE FAULTY". The temperature probe that measures the oven chamber is reporting a faulty reading, so the control system cannot regulate cooking temperature reliably until the probe is checked or replaced.

- On-screen description reports the oven chamber probe is faulty
- Temperature regulation becomes unreliable
- Cooking results inconsistent or the cycle is interrupted
Common causes
- Oven chamber temperature probe faulty
- Damaged or disconnected probe wiring
- Probe out of its measuring range or short-circuited

When to call a professional
Inspecting and replacing the oven chamber temperature probe involves accessing the appliance's internal wiring and control connections, and the manual instructs you to always contact the Technical Assistance Service for error messages. Call a qualified Smeg technician to diagnose and replace the probe rather than opening the appliance yourself when E08 appears.
