Error codeC-70
ApplianceWall Oven
Quick answer
C-70 on a Dacor oven means the steam sensor is open or shorted during operation. The manual gives a restart routine before calling for service.
Model compatibility: Dacor reuses codes across series and model years, so C-70 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
C-70 means the steam sensor is open or shorted while the oven is operating.
A C-70 message tells you the steam sensor has gone open or shorted while the oven is running. The Dacor manuals give owners a short routine to try before they pick up the phone.
Steps from the owner’s manual
Press OFF (CANCEL on some displays) and restart the oven.
If C-70 comes back, disconnect all power to the oven for at least 30 seconds, then reconnect it.
If the code still shows, call for service.
Models with this code
You will find C-70 in the manuals for the Modernist DOB30M977 wall oven, the DOC30*977D* combi oven and the Modernist Pro DOP36/48M86D range, all of them current Dacor series.
If the display shows something close
C-72 is the drain-system code printed in the same table, so check it if the oven reports drainage trouble. C-31 concerns PCB temperature rather than the steam sensor.
