What we can confirm
Code F3, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.

On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Miele dryer error code F3
What Miele publishes for it
On a Miele dryer, the manufacturer publishes this for drying air temperature sensor short-circuited. That sentence is Miele's own, read off its published support page for this condition rather than worked out from the outside. Everything below it — what the condition covers and what is worth doing first — is ours, written from what this equipment does in Miami kitchens.
What this block of conditions is about
Every dryer Miele sells in the United States now is a heat-pump machine, which means the condition on the display is usually about a circuit that has no equivalent in a vented dryer: a compressor, an evaporator and a condensate pump rather than an exhaust duct.
What it covers
What a published cause names is a circuit rather than a component, which is the single most useful thing to know before anybody orders a part. This one covers:
- Drying air temperature sensor short-circuited.
Worth knowing before you call
Miele publishes no owner step against this one, and neither do we. It is a condition for a technician rather than for the person standing in front of it, which is the honest reading of a code with nothing an owner can act on. Have the model and serial number ready and it becomes a short conversation rather than a long one.
What a visit does first
A sensor circuit reported short or open is measured before anything is replaced: a resistance at a known temperature against the maker's curve, then the loom back to the board. Roughly as often as not the sensor itself is sound and the run to it is not — a connector that has corroded in a humid South Florida laundry room or under a kitchen floor — and that is a much smaller repair than the part number suggests.
Then what
This is not a filter and not a setting. A Miele heat-pump dryer has a sealed refrigerant circuit, and its conditions point at the compressor, the evaporator or the sensors reading them — none of which is an owner's job and none of which is improved by running the machine again. Twenty-four of the twenty-eight conditions this maker publishes for its dryers are in that group, which is the shape of a heat-pump machine rather than a sign that yours is unusual.
Miele publishes this one for the heat-pump dryers. The full Miele archive has the other conditions, searchable, and on this make the same number appears on more than one machine roughly a third of the time, so the appliance above is part of the answer. We repair this equipment across Miami-Dade, Broward and Palm Beach.
