What 12:00
actually means.

Miele's appliances can hold the time through a short outage, but not a long one. After more than 150 hours without power, the M 7240 TC and the speed ovens start again at 12:00 and need the time, and on the speed ovens the date, set again.

What to do when 12:00 shows on the microwave

Before you book,
in this order.

Each step comes from Miele's own guidance for 12:00 on its microwaves. Follow it to the end: the last card says whether this is a visit.

01

Set the time of day, and on a speed oven the date as well.

02

Check that your preferred settings, such as the clock display, are still as you like them.

03

If 12:00 returns without a long outage, book a visit, because the appliance is losing its supply or its memory.

Still there?

It usually turns into microwave diagnostic visit. Book with the code and the model number.

What not to do

12:00 is not the Power Failure message, which follows a brief interruption during cooking. It is also not a sign of damage to the microwave from the outage.

What you may
notice with it.

The microwave problems 12:00 tends to arrive with. Answer these at the microwave before anyone is booked.

Questions
about 12:00.

Can I clear 12:00 myself?
Set the time of day, and on a speed oven the date as well. If it comes back, it needs a visit.
We were away for two weeks and our Miele microwave shows 12:00. Is it broken?
No. That is the long-outage reset: after more than 150 hours without power, the clock starts again at 12:00.
Why does my Miele speed oven show 12:00 after a short outage?
Miele ties 12:00 to outages over 150 hours. Seeing it after a short cut is unusual and worth a visit.
Can my Miele microwave be used before I set the time?
Setting the time first is the sensible start; the instructions treat 12:00 as a request to set it.

Back to your everyday

Still showing 12:00?

Three details make the booking useful: the characters or beeps just as they appeared, every character of the model number, and whether a cup of water still warms up. With those, the technician arrives already halfway to the answer.
