Error codeC-72
ApplianceWall Oven
Quick answer
C-72 on a Dacor oven or range signals a drain system problem. The manuals list the meaning only.
Model compatibility: Dacor reuses codes across series and model years, so C-72 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-72 signals a problem with the drain system.
C-72 is a short entry in the Dacor information-code tables: it signals problems with the drain system. The manuals print the meaning and no owner routine for it.
Where C-72 applies
Dacor lists it for the current Modernist DOB30M977 wall oven, the DOC30*977D* combi oven and the Modernist Pro DOP36/48M86D range.
Handling it
With no steps in the manual, treat C-72 as a service matter and avoid opening panels or taking anything apart. Turn the oven off and write the code down so you can pass it on.
Related codes
Sitting right after it in the tables is C-A2, the cooling motor code. C-70 covers the steam sensor, which is a different circuit from drainage. For a high PCB reading, see C-31.
