What U
actually means.
On the all-electric Château stoves, U in a zone's display means no pan is detected or the pan is not suitable for induction. While U shows you cannot turn the power up, and it clears as soon as a pan the zone can heat is placed on it.

What to do when U shows on the stoveKind of codeStovetop elements
A burner on an electric or induction stovetop did not heat the way the knob or key asked, heated with nothing set, or ran hotter than the setting. The pan, a lock left on and the switch behind the knob are checked before the element under the glass, its limiter or an induction board is changed. If a burner keeps heating after it has been switched off, turn the stove's breaker off before anything else.

Before you book,
in this order.
Each step comes from La Cornue's own guidance for U on its stoves. Follow it to the end: the last card says whether this is a visit.
Hold a magnet to the pan's base. Cast iron, steel and magnetic stainless will work; copper, aluminum, glass and ceramic will not.
Use a pan wide enough for the zone, since a pan that is too small will not be detected.
Set the pan in the middle of the zone, and book a visit if U remains with a pan that should work.
What not to do
Most of the time U has nothing to do with a failed zone. It usually points to the pan, whether its material or its size.
