What L
actually means.
Smeg's child lock stops the cooktop from being switched on by mistake. It is set with the cooktop on and all zones off, by pressing and holding any zone display and sliding along the bar, and the displays then show the lock symbol.

What to do when L shows on the cooktopKind of codeMode, not a failure
A state the cooktop was put in, or one it picked deliberately — a child lock, a demo mode that lights the keys but heats nothing, a residual-heat letter over a zone that is still warm, a prompt that no pan has been found. Nothing has broken and no part is called for.
Usually leads toNo repair
Follow the child lock steps in the Smeg manual to switch it off.

Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element.

Before you book,
in this order.
Each step comes from Smeg's own guidance for L on its cooktops. Follow it to the end: the last card says whether this is a visit.
Follow the child lock steps in the Smeg manual to switch it off.
Look for the lock symbol on the displays before assuming the cooktop has no power.
If the lock will not release, book a visit.
Cleared?
The cooktop came right without a new part. If the same message returns while a zone or burner is on, or the top shuts itself down again mid-meal, treat it as a fresh problem and book it.
What not to do
An L does not mean the cooktop has lost power or failed. The lock is a feature.
