Display shows EC and unit may not cool properly or may shut down intermittently.

Safety first: Unplug the wine cooler or switch off the dedicated circuit breaker before removing any panels. Use a non-contact voltage tester to confirm power is off.

• Power reset: Disconnect power for 5–10 minutes, then restore power. If EC clears and does not return, it may have been a transient fault.
• Check supply voltage: Verify the outlet supplies a stable 120 V AC using a multimeter. Avoid extension cords and power strips.
• Inspect control connections: Remove the upper grille or control panel trim (per Wolf service manual). Check the main control board harness plugs for looseness, corrosion, or heat damage. Reseat each connector firmly.
• Look for board damage: With power still off, inspect the electronic control board for burnt spots, bulging capacitors, or cracked solder joints.
• If EC persists: The main control board is likely defective and should be replaced. Label all connectors before removal. If you are not experienced with electronics, contact a Wolf-authorized technician.
