What ER03
actually means.
ER03 on the Smart Burner knob is a low-battery warning for the Hestan Cue pan. The pan carries a battery so it can report its temperature to the burner.

Something the range was told to do, or a state it chose on purpose — a control lock, a Sabbath setting, a demo mode that lights the display but never heats, a pan warning on an induction zone. Nothing has worn out, and no part is needed.

Before you book,
in this order.
Each step comes from Hestan's own guidance for ER03 on its ranges. Follow it to the end: the last card says whether this is a visit.
Replace the battery in the Cue pan.
Until then, the Smart Burner can be run in Manual Mode like the other burners.
Cleared?
The range was set right without a new part. If the same message comes back while a burner or the oven is in use, or the range cuts out again, treat it as a new problem and book it.
What not to do
ER03 is not a problem with the range itself; nothing needs repair.

Mode, not a failure on other makes
Gas range
Open flames on top and a gas-fired oven below, all fed by one supply line behind the range and lit by igniters rather than a match.
Dual-fuel range
Gas burners on top and an electric oven below, the combination most professional-style ranges use, needing both a gas line and a 240-volt circuit.
Induction range
A glass top that heats the pan itself through copper coils and power boards, over an electric oven, with electronics doing almost all the work.
