Press OFF and give the oven a fresh start. If it comes back, it needs a visit. ### Can I still bake normally with C-70 on my Samsung oven? The code concerns the steam system. Reset the power first, and if C-70 keeps appearing, book a visit before relying on the steam functions. ### Does C-70 mean the Samsung reservoir is empty? No. It is about the steam sensor circuit, not the water level. --- **[Read on the site: Samsung wall oven showing C-70 | OvenRepair.center](https://ovenrepair.center/error-codes/samsung-c-70/)** **[Book a visit with OvenRepair.center](https://ovenrepair.center/schedule/)**
