Symptom
Miele steam oven is asking to be descaled
The reminder is calculated from a water-hardness figure set at the factory, and South Florida water is harder than that figure — so on this coast the message arrives after the scale, not before it.

Three ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.

Scale in the generator
What the reminder is about, and what descaling clears.

The nozzle
A separate job that gets skipped, and the one that keeps coming back if it is.

How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About Miele steam oven is asking to be descaled
The fastest diagnosis is the code
Set the water hardness on the appliance to what your supply actually is. It is a setting, it takes a minute, and it is the difference between a reminder that arrives on time and one that arrives late for the rest of the appliance's life.
The reminder arrives late here, by arithmetic
The appliance counts down to its descaling interval using a water-hardness value that is set on the machine. If that value is lower than the water actually is — and the default is lower than South Florida supply — it counts too slowly and asks too late. Setting it correctly is a one-minute job that changes every interval afterwards.
The nozzle is a separate job
Running the descaling program does the generator. The nozzle has its own published condition and its own procedure, and skipping it is why some machines are descaled and still steam badly.
