Wipe the control area dry and move any pan, lid or spoon off the keys. If it comes back, it needs a visit. ### Why does my Hestan induction range beep and shut off with Er 03? Something on the controls, usually water or a utensil, is holding a key down. After about 10 seconds the touch control switches off to avoid acting on a press you did not make. ### Is Er 03 on my Hestan induction range the same as the Smart Burner ER03? No. The induction top's Er 03 is about the touch keys, and the Smart Burner's ER03 is a pan battery warning on a different model. --- **[Read on the site: Hestan induction range showing Er 03 | RangeRepair.center](https://rangerepair.center/error-codes/hestan-induction-er03/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
