Display shows E0 and the wine cooler does not cool or respond to temperature changes.

Safety first: Unplug the wine cooler from the wall outlet before removing any panels. Do not work on live circuits.

Steps to check and correct:

• Power reset: Unplug the unit for 5–10 minutes, then plug it back in. If E0 clears and does not return, it may have been a temporary logic glitch.
• Inspect control board connections: Remove the rear access panel (usually held by Phillips screws). Locate the main control board (PCB) used in BODEGA wine coolers, typically mounted near the compressor area. Check all wire harness plugs for a firm fit and signs of corrosion or burning.
• Check for moisture or insect damage: Look for condensation, rust, or insect nests on the PCB. If present, carefully clean with a soft brush and isopropyl alcohol (with power disconnected) and allow to dry completely.
• Check incoming voltage: With a multimeter and the unit plugged in (only if you are trained and comfortable working with live voltage), verify that the board is receiving 110–120 VAC at the input terminals. If no power is present, check the outlet and house breaker.
• Replace the main PCB if needed: If connections are good and power is present but E0 persists, the main control board is likely defective and should be replaced with a compatible BODEGA wine cooler main PCB. Transfer one connector at a time to avoid miswiring.

When to call a professional: If you are not comfortable testing live voltage or replacing the PCB, contact a qualified appliance technician.
