DOOR-AJAR Door Not Sealing — Gasket Compression Lost Medium The BW-series control detects that the door switch is not fully actuating, triggering the door-ajar alarm on a recurring cycle even though the door looks shut from the outside. View EC10 Upper Cabinet Warm Temperature Alarm High Wines stored in the upper zone of the Classic Wine Storage unit are warmer than expected when handled, particularly whites and sparkling wines kept there for service temperature. View EC12 Lower Cabinet Warm Temperature Alarm High Wines in the lower BW-series storage zone are warmer than the displayed setpoint, particularly noticeable on reds stored there for long-term cellaring. View EC15 Sealed System Fault High After several hours with the unit running, wine bottles throughout the BW-series cabinet are no longer noticeably cooler than ambient room temperature. View TEMP-DRIFT Gradual Cabinet Temperature Drift Above Setpoint Medium White wines that should be served at 50°F feel closer to 55–58°F, or reds set for 60°F feel closer to 65°F — a persistent, gradual increase over several weeks rather than a sudden change. View ZONE-MISMATCH One Zone at Setpoint, Other Zone Fails to Reach Setpoint Medium When you check both zones — for example, an upper 55°F red wine zone and a lower 45°F white wine zone — one reads correctly and the other reads 5°F or more above its setpoint.
