What H
actually means.
H is Smeg's residual heat warning. After a zone is switched off, the display keeps showing H while the glass is still hot, and it disappears once the temperature drops below 140 °F.

What to do when H 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
Keep hands and children away from that zone until the H goes out.
Shows up asCooktop Hot Surface Light Stays On
The hot surface light or residual heat indicator stays lit long after the glass has cooled, or it never comes on at all.

Before you book,
in this order.
Each step comes from Smeg's own guidance for H on its cooktops. Follow it to the end: the last card says whether this is a visit.
Keep hands and children away from that zone until the H goes out.
Do not wipe the zone or set anything heat-sensitive on it until the H goes out.
If the H stays lit on a cooktop that has been off and cold for a long time, 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
H is not a warning that something is wrong. It is a safety reminder about hot glass.
What you may
notice with it.
The cooktop problems H tends to arrive with. Answer these at the cooktop before anyone is booked.
