Error codeF0
ApplianceCooktop
F0 in plain terms
Inside Modernist induction cooktops DTI30M977BB and DTI36M977BB there are two boards, a main PCB and a sub PCB. F0 is displayed when communications between them have failed.
Manual steps
Press POWER to restart the cooktop.
If F0 stays on, disconnect the power supply for more than 30 seconds.
If F0 survives two restarts, ring (415) 687-5926 and we can arrange Dacor cooktop and rangetop repair in the San Francisco Bay Area. Have the F0 code, your model number and a note about both restarts ready.
Model compatibility: Dacor reuses codes across series and model years, so F0 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
F0 means communications between the main PCB and the sub PCB failed.
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.
Seeing this code on your Dacor appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A2 flags a fault with the fan motor of a Modernist induction cooktop. Its DC motor stops running because of the PCB, the wiring or a blade that is blocked.
C0 is the Modernist induction cooktop message for an open top sensor. The manual answers it with a restart, then a power cord unplugged for at least 30 seconds.
C1 signals a shorted top sensor on Modernist induction cooktops. It also appears when abnormal operation overheats the cooktop and it shuts itself off.
