# Dryer error code EF1

### What EF1 means on this make

The dryer has measured its own airflow and found it insufficient. This is the most important code on this list and the one we would most like people to act on, because a blocked dryer vent is a fire before it is a repair. The maker sends it to the installer rather than to service, and in a South Florida condominium that is more reasonable than it sounds: these runs go up through a wall to a roof or a soffit, they are long, they have elbows, and the part that blocks is usually the far end nobody can see. A dryer that takes three cycles to dry a load is telling you this before the code does.

### Where this appears, and why not to clear it

On the appliance’s own display, as a short single code — a letter and a number, or two letters. Nothing alternates and nothing arrives in halves on this make, so what the panel shows is the whole of it. Photograph it before you cut the power. This maker’s own answer to most of these is thirty seconds at the breaker, and that is worth following once — but a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again.

### What to do about it

- Clean the lint filter — and then look through it against a light. A film of softener residue passes lint and blocks air, and it is invisible in the hand.
- Pull the machine out and check the flexible hose behind it for crushing. A dryer pushed back to close a closet door folds its own vent.
- Find the outside end of the run and look at it. A flap held shut by lint, a bird’s nest, or a screen somebody fitted are the three things we find.
- If the run is long or goes through a wall, have it cleaned properly rather than poked at. This is the one item on this page where doing nothing is genuinely unsafe.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 912-9018](tel:+13059129018) and describe what the panel is doing before booking anything.

Ventilation Blockage. Check lint filter (blocked/lint). Check the exhaust tube for bends, restrictions and blocks. Check vent exit for any blockage. Clean and clear any debris in the way. This is a known installation issue, please contact your installer.
