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. Hestan cooktop display What to do when ER01 shows on the cooktop ### Kind of code Mode, 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 to No repair Set the Cue pan back squarely on the Smart Burner. ### Shows up as Cooktop Burner Won't Light The igniter clicks but the gas never catches, the burner lights only after several tries, or nothing happens at all when the knob is turned. ### Make Hestan A California maker of pro-style gas cooking, with rangetops for the home kitchen. ### Source Hestan KRT and KRTS rangetop use and care manual, Smart Burner error codes Hestan KRTS smart rangetop, Smart Burner only; the KRTS is not in Hestan's 2026 indoor catalog. KRT rangetops without the Smart Burner show no ER codes. ## 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. 01 Set the Cue pan back squarely on the Smart Burner. 02 Restart the cooking step. 03 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. ## What you may notice with it. The cooktop problems ER01 tends to arrive with. Answer these at the cooktop before anyone is booked.

Set the Cue pan back squarely on the Smart Burner. ### Why does my Hestan Smart Burner say ER01 when I lift the pan? Taking the pan away stops the burner seeing it heat, which sets ER01. Put it back in place. ### Does ER01 mean my Hestan burner is broken? No. It is about the pan's position, not the burner. ### Can the pan position trigger ER01 on a Hestan KRTS Smart Burner? Hestan names a pan not properly positioned on the burner, or one lifted off, as the cause, since the burner then cannot see the pan temperature rise. Center the Cue pan on the Smart Burner and restart the step. --- **[Read on the site: Hestan smart rangetop showing ER01 | CooktopRepair.center](https://cooktoprepair.center/error-codes/hestan-er01/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
