With the oven cool, gently clean the moisture sensor with a damp cloth.
The sensor is usually located inside the cavity — consult your La Cornue manual for its exact position.

Power cycle
Turn off breaker for 2 minutes and retest.
Cleaning followed by a power cycle often resolves E6.

Use manual modes
Switch to manual temperature and time settings instead of automatic programs.
Manual modes bypass the moisture sensor entirely.
