Turn the burner off and let it cool; if you smell gas, leave the knobs off, leave the house and call the gas utility from outside. If it comes back, it needs a visit. ### Why did my Hestan Smart Burner give up and show ER05? It tried several times to light and could not, so it stopped the cycle to avoid releasing gas. Clogged ports or a worn igniter are the usual reasons. ### How do I clean the burner ports on my Hestan stove? With the burner cool, lift off the cap and clear the ports with a stiff brush or a straightened paper clip. Keep water out of the igniter and let everything dry before lighting. ### Should I worry about gas when ER05 shows on my Hestan stove? The stove stops the cycle after the failed attempts. If you smell gas, do not try again; leave and call the gas utility from outside. --- **[Read on the site: Hestan Smart Burner showing ER05 when it will not light](https://stoverepair.center/error-codes/hestan-er05/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
