What HH
actually means.
On Marvel Professional wine units, HH is the high temperature notice. It appears when a compartment has been warmer than the control setting for an extended time. Marvel’s guide gives no owner steps beyond contacting service, so the first checks are the door, the grille and the room.

What to do when HH shows on the wine coolerKind of codeTemperature and alarms
The cooler read a zone well away from its setting and raised an alarm, sometimes showing the warmest figure it reached while the house was empty. The reason may be as small as a door left resting on a bottle neck or a long outage, or as serious as cooling that has stopped. Keep the glass door shut and feel a bottle in the middle of the rack before doing anything else; the alarm is a warning about the wine, not a diagnosis.

Testing and replacing the thermostat or the temperature sensors that tell a wine cooler when to cool, when the cabinet runs too cold, too warm or back and forth.

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 Marvel's own guidance for HH on its wine coolers. Follow it to the end: the last card says whether this is a visit.
Check that the door closes and seals and that nothing blocks the front grille.
Measure the warm zone with a thermometer in a glass of water left for an hour.
If HH stays, move your best bottles somewhere cool and dark and book a visit.

What not to do
HH is not a sensor code; the control is reading real warmth. It also does not by itself mean the compressor has failed; a door or airflow problem can cause it too.
