What C-70
actually means.
C-70 appears on Dacor dual-fuel ranges that have a water reservoir for steam cooking. It says the steam sensor reads open or shorted while the oven is running.

What to do when C-70 shows on the rangeKind of codeTemperature sensor
The oven sensor sent a reading the control would not accept, or one that climbed well past the setting. A loose plug or a sensor that has drifted is ruled out before the control board, and a temperature that keeps rising means the range is switched off at the breaker first.
Usually leads toTemperature sensor and thermostat repair
A range oven that bakes hot, bakes slow, takes forever to preheat or posts a sensor code, traced to the sensor probe, the thermostat or the calibration.
Shows up asRange Oven Not Heating
The burners or elements on top work, but the oven below stays cold, heats only a little, or never finishes preheating.

Before you book,
in this order.
Each step comes from Dacor's own guidance for C-70 on its ranges. Follow it to the end: the last card says whether this is a visit.
Turn both the mode and temperature knobs to OFF and restart.
If it persists, disconnect all power for at least 30 seconds; if C-70 still returns, book a visit.

It usually turns into temperature sensor and thermostat repair. Book with the code and the model number.
What not to do
C-70 is not a signal that the reservoir is empty or needs descaling; it reports the sensor itself.

Dacor range repair
Gas range
Open flames on top and a gas-fired oven below, all fed by one supply line behind the range and lit by igniters rather than a match.
Dual-fuel range
Gas burners on top and an electric oven below, the combination most professional-style ranges use, needing both a gas line and a 240-volt circuit.
Induction range
A glass top that heats the pan itself through copper coils and power boards, over an electric oven, with electronics doing almost all the work.
