# Miele dryer error code F30

### What Miele publishes for it

On a Miele dryer, the manufacturer publishes this for door signal and door contact signal are different. 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:

- Door signal and door contact signal are different.

### 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 lock condition is opened without levering it — there is a way in, and a forced door takes the catch and sometimes the panel. Then the alignment is set as part of the job, because a lock asked to hold a door that has dropped fails again within months.

### 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](https://mielemiami.support/error-codes/) 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.
