The error code E2 on the CANDY CCVB120 wine cellar means that there is a fault with the defrost probe of the device. This probe is responsible for controlling the automatic defrost cycle that activates every 6 hours for 30 minutes.
When the E2 error appears on the LCD screen flashing, it indicates that the defrost probe is not functioning properly. The issue may stem from either the probe itself or the wiring that connects it to the device's electronic board. In this case, the device enters degraded mode: it continues to operate normally for wine preservation, but the defrost cycle switches to a backup mode of about 45 minutes.
Before contacting customer service, check that the device is properly plugged in and that the power outlet is working. Turn off the wine cellar, wait 3 to 5 minutes, then plug it back in to perform a complete restart. Also, ensure that the door closes properly and that the seal is not damaged, as this could affect the internal sensors.
If the E2 error persists after restarting, replacing the defrost probe will be necessary. This repair requires the intervention of a certified Candy customer service professional, who has the appropriate spare parts and the skills to accurately diagnose whether the problem lies with the probe or the wiring. Do not attempt to repair this component yourself, as it is part of the electronic temperature control system. The device can continue to be used in degraded mode without risk to the wine while waiting for the repair.
