What to check, in order
- Clean the lint filter
Properly, not just a quick wipe.
- Check the vent hose
Follow the whole run behind the dryer for lint build-up, crushing or kinks.
- Clear it rather than reset it
A blocked vent is both the usual cause and a fire risk, so clear it thoroughly instead of just clearing the code.
When to call an engineer
If the duct runs through walls or ceilings and you can't reach it.
Parts people end up buying
Only if the checks above point to a part. Match it to your model number first: it's on a label inside the door, around the door frame or on the back.

About this code
Unbranded and less common appliances don't publish one shared code list, so this page gives the most common meaning across makers. Your manual is the final word, and the model number that finds it is on a label inside the door, around the door frame or on the back.
