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 Miele writes the condition as F and a number on the W1 machines and on the professional Little Giants alike, and the numbering runs further here than on anything else it builds — past F200 and past F300. The high numbers are not more serious than the low ones; they are a later block of the same list. ### 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 Thermostop has been activated. - The Thermostop function ensures that the set program temperature is reached. - The Thermostop starts if the set temperature has not been reached within the specified time. While Thermostop is running, the time left display pauses. - As soon as the desired temperature is reached, the wash program resumes and the time left display starts to count down again. - There is a technical condition. There is a condition with the heating. - At least 2 minutes - Before reconnecting the washing machine to the power supply. - Then switch the washing machine on again. ### Worth trying yourself, in this order - Disconnect the washing machine/washer-dryer from the power supply. Unplug the appliance or switch off the breaker. - Wait - Restart the program. ### Then what Try it in that order before booking anything. A Miele washer is a machine that reports precisely, so when a code clears after the owner has done what the maker asks, it has usually told the truth about what was wrong. If it comes straight back on a machine you have already reset, stop repeating the cycle: on the W1 and the Little Giants alike, a repeated lock or drain condition is a part, and running it again with a load in it only leaves you with wet laundry. Miele publishes this one for the washing machines. 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. washing machine What this one means What Miele publishes for it On a Miele washing machine, the manufacturer publishes this for the Thermostop has been activated.
