The electronic boards inside the range have lost communication with each other. A power reset often clears it, and on some newer induction models a software update fixes it.
Likely causes
Listed from most to least common.
- Temporary glitch after a power surge or outage
- Outdated software on some induction ranges
- Loose wiring harness between the control boards
- Faulty main or sub control board
How to fix the C-F0 code
Unplug the oven or switch it off at the breaker before removing any panel or filter.
Step 1: Turn the range off and on
Press the Power or Off button, wait a few seconds and turn the range back on.
Step 2: Reset at the breaker
If the code returns, switch off the circuit breaker for the range for at least 30 seconds, then turn it back on.
Step 3: Update the software
On Samsung induction ranges with Wi-Fi, connect the range to the SmartThings app and leave it on so it can download any software update. Samsung lists this fix for some NSI6D induction models.

Common questions
›What causes the C-F0 code on a Samsung range?
The control boards inside the range stopped talking to each other. It can be a one-off glitch after a power blip, or a sign of a failing board if it keeps coming back.
›Is C-F0 the same as C-F1 or C-F2?
No. Samsung uses C-F1 for a memory read or write error and C-F2 for a touch control communication fault. The first fix for all three is the same power reset.
