Quick answer
LG dryer F0: the lint filter is not seated. Reinsert it.
Model compatibility: LG 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.

What this code means
Lint filter not seated properly (flashing INSERT FILTER).
An F0 display code, or a flashing insert filter message, on an LG dryer indicates that the lint filter is out.
