Error codeC-d0

Why the display shows C-d0
When a control key stays shorted for 1 minute, the oven puts C-d0 on the display. Of the codes in this group, it is one where Dacor gives the owner something to do at the panel.
Steps in the manual, in order
Wipe and clean the buttons.
Check that no water or moisture sits on or around them, and dry the area if it does.
Turn the oven off, then try it again.
Should the code come back, get in touch with Dacor.
Which models list it
Modernist wall oven DOB30M977
Combi oven DOC30*977D*
Both are in the current series.
Easy to confuse with
C-d1 sits directly beneath it in the table and refers to the door lock.
C01 is a shorted key entry too, but it is from the legacy Renaissance ovens.
C02 is a touch panel fault taken from the service manual.

If C-d0 returns after you have cleaned and dried the panel, ring (415) 687-5926 and mention that you already did both. Details on what we handle are under Dacor wall oven repair, and the oven model number helps when you call from anywhere around the Bay Area.
Model compatibility: Dacor reuses codes across series and model years, so C-d0 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-d0 means a control key has stayed shorted for 1 minute.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
