What ER01
actually means.
ER01 on a Hestan Smart Burner means it did not detect the pan temperature rising. The usual cause is a pan that is not properly positioned on the burner, or one that was lifted off.

What to do when ER01 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
Set the Cue pan back squarely on the Smart Burner.

Before you book,
in this order.
Each step comes from Hestan's own guidance for ER01 on its cooktops. Follow it to the end: the last card says whether this is a visit.
Set the Cue pan back squarely on the Smart Burner.
Restart the cooking step.
Keep the Cue pan in place for the rest of the step so the burner can track its temperature.
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
ER01 is not an ignition problem; the burner may be lit and working. It means the burner did not see the pan temperature rise.

notice with it.
