What to do when ER03 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.

Replace the battery in the Cue pan.

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 Hestan's own guidance for ER03 on its cooktops. Follow it to the end: the last card says whether this is a visit.
Replace the battery in the Cue pan.
Let the Cue pan cool before you open it to change the battery.
If ER03 stays with a fresh battery in the pan, 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
ER03 is not a burner or rangetop problem. It is a low battery warning from the Cue pan.
What you may
notice with it.
The cooktop problems ER03 tends to arrive with. Answer these at the cooktop before anyone is booked.
