# Miele oven error code F27

### What Miele publishes for it

On a Miele oven, the manufacturer publishes this for the power supply was interrupted during operation. 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

One block covers the wall ovens, the combi-steam ovens, the speed ovens and the warming and vacuum-sealing drawers, because Miele builds them on one control family. The steam side adds a set of its own about water: the intake valve, the nozzle, the container and the conductivity of the water itself.

### The other label for the same condition

Miele’s own table prints this one under more than one token, on the same row and against the same meaning:

- **F27, E04** — one condition, two ways the panel writes it

### 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:

- The power supply was interrupted during operation.
- Enter a new cooking duration if necessary.
- Button to continue operation.
- Is displayed on the program/temperature display if the power supply was interrupted during the descaling program.
- Appears on the time display.
- Let the time run down.

### Worth trying yourself, in this order

- Check the cooking progress.
- Press the
- Start/Stop
- Turn the steam oven off and then back on again.

### Then what

Most of the oven and steam-oven conditions on this make are genuinely an owner’s job — twenty of the twenty-five Miele publishes — and most of them are about water or about something in the cavity rather than about electronics. If yours is a combi-steam oven, assume scale until proved otherwise: the water here is hard, descaling is the maintenance this appliance actually needs, and a machine that is descaled on schedule reports very little.

Miele publishes this one for the ovens, steam ovens and the drawers — that is ovens, steam ovens and drawers on this site. 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.
