What ER02
actually means.
ER02 on a Hestan Smart Burner means the Bluetooth connection to the Cue pan was lost. Hestan points to a dead or low pan battery, or a problem in the pan.

What to do when ER02 shows on the cooktopKind of codeBoards and communication
The touch board and the power board under the glass lost track of each other, or one failed its own start-up check. A power dip, a ribbon or harness pulled loose when the top was fitted, or moisture from a boil-over is ruled out before a board is replaced, and a cooktop that keeps heating while this code shows is switched off at the breaker.
Usually leads toTouch control repair
Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting.
Shows up asCooktop Controls Unresponsive
Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element.
