What C-70
actually means.
On Samsung ovens with steam cooking, C-70 reports a steam sensor that reads open or shorted while the oven runs. Steam Bake and Steam Roast depend on that reading.

What to do when C-70 shows on the ovenKind of codeSteam and water
The steam oven found its water tank empty, its supply short, or its steam generator slowed by scale. Refilling and seating the tank and running the descaling program come first; a pump, a level sensor or the generator is looked at only after that.

A steam or combi-steam oven that makes no steam, weak steam or asks for water it already has, traced to scale, the pump, the generator or the tank sensor.

Before you book,
in this order.
Each step comes from Samsung's own guidance for C-70 on its ovens. Follow it to the end: the last card says whether this is a visit.
Press OFF and give the oven a fresh start.
If the code persists, disconnect all power for at least 30 seconds.
Book a visit if C-70 comes back.
What not to do
C-70 is not a request to fill or drain the reservoir; drain problems have their own code, C-72.
