What Demo mode
actually means.

Demo mode lets a Gaggenau combi-microwave show every function on a showroom floor without producing heat. To leave it, you briefly cut power at the breaker and then switch demo mode off in the basic settings within three minutes of power returning.

What to do when Demo mode shows on the microwave

Before you book,
in this order.

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

01

Switch off the household breaker for a moment, then switch it back on.

02

Within 3 minutes, open the basic settings and set demo mode to off.

03

If the display then shows Initialization, complete the initial start-up.

04

If the unit still does not heat with demo mode off, 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

The demo symbol is not a failed magnetron or heating element. Missing the three-minute window just means repeating the breaker step.

What you may
notice with it.

The microwave problems Demo mode tends to arrive with. Answer these at the microwave before anyone is booked.

All problems

No repair indicated

Nothing to repair.

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.

In Gaggenau's own words

The appliance is in demo mode.

Questions
about Demo mode.

Can I clear Demo mode myself?
Switch off the household breaker for a moment, then switch it back on.
Why does my Gaggenau combi-microwave light up but stay cold?
Look for the demo mode symbol. In demo mode it will not heat.
Why does Gaggenau make me cut the power to leave demo mode?
The setting can only be changed in the first three minutes after power returns, which stops it being switched by accident.
My Gaggenau showed Initialization after I switched off demo mode. Is that normal?
Yes. Gaggenau notes that turning demo mode off after it was set during start-up sends the unit back to initial setup.

Back to your everyday

Still showing Demo mode?

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.
