Error codeC1
ApplianceCooktop
Quick answer
C1 means the top sensor is shorted. The cooktop turns off when it overheats from abnormal operation and shows C1.
Model compatibility: Dacor reuses codes across series and model years, so C1 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
C1 means the top sensor is shorted.
Meaning of C1
C1 stands for a shorted top sensor on the Modernist induction cooktops DTI30M977BB and DTI36M977BB. The manual’s safety shutoff section adds that if the cooktop overheats because of abnormal operation, C1 is displayed and the cooktop turns off.
What the manual suggests
Turn the cooktop off and restart it. If C1 is still there, unplug the power cord for 30 seconds or more, reconnect it, and then contact a Dacor service center when the problem is not resolved.
Neighbouring codes
An open sensor is reported as C0, and C2 points at the IGBT sensor. For a keypad problem instead, see d0.
