What DemoMode
actually means.
Touch & Swipe models show a D in the display when DemoMode is active; the note in the manual says to deactivate it before the countdown finishes when switching on. On HW columns, a unit that shows a value but whose cooling does not start after plugging in is in demo mode, and Liebherr asks owners to contact service.

What to do when DemoMode 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.

Look for the D 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 Liebherr's own guidance for DemoMode on its wine coolers. Follow it to the end: the last card says whether this is a visit.
Look for the D in the display.
On Touch & Swipe models, follow the switch-on steps and deactivate DemoMode before the countdown ends.
On an HW column, or if cooling still does not start, book a visit.
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
DemoMode is not a compressor failure. If the D is gone and the cabinet still does not cool, a technician needs to check the cooling system.
