What Initialization
actually means.
The Expressive series shows Initialization the first time it is switched on after connection, if that setup was not completed, after a factory reset, or after demo mode set during start-up has been switched off. The unit expects language, units, time format and the time before normal use.

What to do when Initialization shows on the microwaveKind of codeMode, not a failure
Something was switched on rather than something wearing out: a child or control lock set by a long press on the wrong pad, after which no key answers, a demo or showroom setting that lights the display and turns the plate while nothing warms, a Sabbath setting that dims the panel and mutes the beeps, or a clock left blinking after an outage that holds the keypad until it is set. No part is needed; a key sequence from the manual switches it off again.
Usually leads toNo repair
Work through the initial settings on the display: language, Home Connect, temperature and weight units, time format and time.
Shows up asWhat a Microwave Error Code Is Telling You
A microwave error code may be a letter and a number on the display, a lock or demo word, a row of dashes, or a beep with a blinking clock, and it can show while the microwave still heats or block every key until it is cleared.

Before you book,
in this order.
Each step comes from Gaggenau's own guidance for Initialization on its microwaves. Follow it to the end: the last card says whether this is a visit.
Work through the initial settings on the display: language, Home Connect, temperature and weight units, time format and time.
Finish every step; leaving the setup partway brings the screen back.
If Initialization reappears after a completed setup with no factory reset, book a visit.
Cleared?
The code has gone and a mug of water heats again without a new part. If it comes back this week, or the food starts coming out cold in the middle, mention in the booking that it came back.
What not to do
Initialization is not an error and does not mean memory has failed. It is expected after a factory reset or after leaving demo mode.
What you may
notice with it.

Still showing Initialization?
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.
