What ER01
actually means.
ER01 appears on the knob display of Hestan's Smart Burner, the connected burner on KRDS models that works with a Cue pan. It means the burner was heating but the pan's temperature did not climb, usually because the pan is off-center or was lifted away.

What to do when ER01 shows on the rangeKind of codeBurners and ignition
A burner was asked to light and the range did not sense a flame, or the spark kept firing after the flame was there. Moisture or food in the igniter and a cap sitting out of place are ruled out before the spark module or a switch is replaced. A smell of gas outranks any code: leave the house and phone the gas utility from outside.
Usually leads toBurner and igniter repair
Gas burners that will not light, keep ticking or burn with a weak, yellow or uneven flame, traced to the igniter, the spark switch, the module or the burner itself.
Shows up asUneven Range Burner Flame
A gas burner flame is taller on one side, has gaps, burns yellow or orange, lifts off the burner, or roars instead of burning quietly.

Hestan range repair
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.
