Quick answer
IF on a WashTower dryer means the lint filter is not detected. Check both filter parts and the magnet.
Model compatibility: LG reuses codes across series and model years, so IF 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
Lint filter not detected (WashTower dryer).
IF shows on the dryer half of an LG WashTower when the machine cannot detect the lint filter.
What to check
Take out the lint filter and look at both parts of it. Make sure both parts are in place, and that the magnet is in place too. After checking, run the dryer again.
If IF stays on the display even though the filter looks right, request service.
