Low Medium High

Code Meaning Severity Common Symptom

CC Compressor control fault High Stored wines gradually warm toward room temperature as the compressor ceases operation and the sealed refrigeration cycle stops entirely. View DE Door open too long Low The ZIW wine center's glass door is not fully closed, allowing warm room air to enter the wine compartment and gradually warm stored bottles. View E1 Zone temperature sensor fault High The most observable sign is the E1 fault code on the Monogram ZIW wine reserve display panel. Many ZIW models indicate which zone's sensor has failed. The unit may continue cooling but cannot regulate the affected zone's temperature accurately. View FF Frozen evaporator / defrost fail Medium Stored wines are warming above the target temperature as the iced evaporator can no longer absorb heat from the wine compartment effectively. View HI Wine zone temperature too high High The most immediately observable symptom is the HI error code appearing on the ZIW wine reserve's digital display, accompanied by an audible alarm. The display may identify which zone — upper or lower — has exceeded its temperature threshold. View LO Wine zone over-cooling detected Medium The primary observable indicator is the LO error notification on the Monogram ZIW wine reserve digital display. The display may show which zone is affected and the actual measured temperature, which will be lower than the programmed set point. View TC Temperature sensor fault Medium Without a reliable thermistor signal, the ZIW wine center may overcool or undercool, taking wines outside the ideal 45–65°F storage range and potentially damaging them over time.
