Is it safe to keep using it?

Depends on code severity. Low/Medium codes often allow continued use, High severity requires immediate stop.

Can error codes be reset?

Some codes clear after power cycle. Persistent codes indicate underlying issues needing repair.

When should I stop using it?

Stop immediately for water leak codes, burning smell, or any High severity error.

Code Meaning Severity Common Symptom

CHECK CONDENSER Condenser clean reminder Low A fouled condenser coil makes the refrigerant circuit work harder to reject heat. In a warm kitchen or during summer months you may notice both zones running slightly warmer than their set points during the hottest part of the day — a sign the condenser needs attention. View DOOR OPEN Wine column door left open Medium A wine column door open to room air disrupts the carefully maintained humidity balance inside the cabinet within minutes. Bottles stored near the door are first affected — cork tops may feel drier than usual on close inspection during an extended open-door event. View E1 Upper zone probe open circuit High With the probe circuit open, the control board receives no valid temperature reading for the upper zone. The display may show dashes, a fixed default value, or an obviously implausible reading — none of which reflect the real temperature inside the upper zone. View E2 Upper probe short circuit High A shorted probe reports a falsely high temperature to the control board, which responds by commanding continuous cooling. Bottles in the upper zone may feel significantly colder than the programmed set point, and in severe cases frost may form on the exterior glass of the uppermost bottles. View E3 Upper defrost probe fault Medium Without a reliable defrost-termination signal from the evaporator probe, frost accumulates progressively on the upper-zone evaporator coil. The thickening frost layer insulates the coil, reducing heat exchange and slowly degrading the upper zone's ability to maintain its set-point temperature. View E4 Cabinet frost sensor failure High More frost than usual accumulates on the rear interior surface or evaporator fins because the defrost cycle cannot terminate at the correct temperature. View E6 Display-to-board comm failure High The wine column display shows dashes, blank segments, or wildly incorrect zone temperatures because the display module is no longer receiving valid data from the main board. View POWER FAILURE Power outage recorded Medium Both the upper and lower zones of the wine column will feel noticeably warmer than their normal storage temperatures on the first door opening after a power event. Bottles near the glass door may show condensation as cool air meets the temporarily warmer glass. View UPPER OR LOWER ZONE TOO COLD Wine zone below set point Medium Bottles stored in the over-cooled zone feel colder than their usual serving temperature and may develop condensation or a light frost on the glass exterior — a clear sign the zone temperature has dropped below the set-point minimum. View UPPER OR LOWER ZONE TOO WARM Wine zone above set point High Wine stored at correct cellaring temperatures (50–65 °F / 10–18 °C) should feel distinctly cool to the touch. If bottles in either the upper or lower zone feel room-temperature or warm, the zone has been above its set point long enough to affect the wine. View
