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. Smeg cooktop display What to do when L shows on the cooktop ### Kind of code Mode, 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 to No repair Follow the child lock steps in the Smeg manual to switch it off. ### Shows up as Cooktop Controls Unresponsive Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element. ### Make Smeg An Italian maker known for its retro styling, whose US catalog includes built-in cooktops. ### Source Smeg induction cooktop manual (SIMU330D) Smeg SIMU induction cooktops; read from the SIMU330D manual, which Smeg links from the SIMU330D and SIMU336D product pages. The L is printed as a display symbol in the manual rather than as text. ## 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. 01 Follow the child lock steps in the Smeg manual to switch it off. 02 Look for the lock symbol on the displays before assuming the cooktop has no power. 03 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. ## What you may notice with it. The cooktop problems L tends to arrive with. Answer these at the cooktop before anyone is booked.

Follow the child lock steps in the Smeg manual to switch it off. ### Why won't my Smeg induction cooktop turn on a zone after cleaning? Wiping the controls can set the child lock without you noticing. Check the displays for the lock symbol and release it using the manual's steps. ### Can I turn the child lock on with a zone already cooking? Smeg's steps start with the cooktop on and the zones switched off, so set the lock after you have finished cooking. ### Where do I press to set the child lock on a Smeg SIMU330D? Smeg's first step is to press and hold any cooking zone display, with the cooktop on and all zones off, and then slide along the bar. Once it is set, the displays show the lock symbol and the zones cannot be switched on by mistake. --- **[Read on the site: Smeg induction cooktop showing L | CooktopRepair.center](https://cooktoprepair.center/error-codes/smeg-induction-l/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
