About Miele oven error code F23
What Miele publishes for it
On a Miele oven, the manufacturer publishes this for the Self Clean temperature has not been reached. 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.
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 Self Clean temperature has not been reached. This may be caused by significant amounts of residual soiling in the oven compartment.
- For thorough and gentle cleaning of your oven, it is recommended to use the manufacturer's products which also care for your appliance at the same time.
Worth trying yourself, in this order
- Switch off the oven and remove any coarse soiling from the oven compartment, then start the Self Clean process 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 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.
