Error codeF0
ApplianceCooktop
Quick answer
F0 means communication between the main and sub PCBs fails. Restart the cooktop and cut power for 30 seconds.
Model compatibility: Samsung 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 is a communication error: the main and sub PCBs fail to communicate.
F0 is a communication error on Samsung cooktops: the main and sub PCBs fail to communicate with each other. Samsung’s Canadian listing groups it with F1 and F2 and gives the three codes one routine. No particular model is named.
Samsung’s recommended routine
Restart the cooktop with its Power button.
If F0 stays on the display, remove power by pulling the plug or using the circuit breaker, leave it for 30 seconds, and restart.
If it persists after that, request service.
Related communication codes
F1 is another communication error in the same group, and F2 concerns the touch-enabled IC. d0 is a separate stuck button error.
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.
