AF error code on a tumble dryer

Airflow restricted

The dryer can't move enough air through itself, so clothes take much longer to dry and the machine flags it.

Worth repairing?

Deal with it now

Do this today. A blocked dryer vent is a real fire risk, not just the reason clothes need two cycles.

Can you do it yourself?

Easy

About 30 minutes

Before you start

  • Fire risk: don't keep using it as it is.
  • Unplug it before you touch anything inside.

What to check, in order

  1. Clean the lint filter

    Properly, not just a quick wipe.

  2. Check the vent hose

    Follow the whole run behind the dryer for lint build-up, crushing or kinks.

  3. 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.

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.
