What Demo mode
actually means.
Demo mode lets a dealer show the unit with the control panel and lighting working but the compressor off, so the cabinet does not cool. On the under-counter unit a demo symbol lights in the display; on MasterCool a symbol shows and the unit stays warm. Miele says it is not meant for home use.

What to do when Demo mode shows on the wine coolerKind of codeMode, not a failure
A setting someone switched on, often by leaning on the touch panel or left over from the showroom floor, rather than a part that wore out: a demo mode that lights the display and the rack lamps while the cooling never starts, a Sabbath setting that turns off the lights and alarms, a child or control lock that ignores every key press, a reminder that the glass door stood open. The cabinet is fine, and its own keys or its manual switch the mode back off.
Usually leads toNo repair
Look for the demo symbol in the display.
Shows up asWine Cooler Error Code
A wine cooler error code appears as letters and digits on the display, a flashing temperature, dashes where a number should be or a blinking symbol, sometimes with an alarm tone and sometimes while the cabinet stays perfectly cool.

Before you book,
in this order.
Each step comes from Miele's own guidance for Demo mode on its wine coolers. Follow it to the end: the last card says whether this is a visit.
Look for the demo symbol in the display.
Switch demo mode off in settings mode, following the steps in the manual for your model.
Give the unit several hours to cool, and book a visit if it stays warm with demo mode off.
Cleared?
The display has gone quiet and the cabinet is back at its setting without a new part. Should the code reappear this week, or the reds start feeling warm again, book a visit and mention that it came back.
What not to do
Demo mode is not a failed compressor. If the symbol is gone and the unit still does not cool, the sealed system, a fan or the control needs checking.

Undercounter wine cooler
A wine cooler about the height of a base cabinet, built in under the counter of a kitchen, a bar or a butler's pantry, with a glass door, sliding racks and a vented toe grille at the floor.
Wine column
A full-height built-in wine cabinet, 18 to 30 inches wide, set flush into tall cabinetry or paired with a matching column, with a glass or panel door and dozens to well over a hundred bottles inside.
Dual-zone wine cooler

In Miele's own words
the compressor remains turned off, so that the appliance does not cool down.
