Display shows E16 and the unit may stop cooling after a short run; compressor protection may be active.

Safety: Unplug the wine cooler and allow the compressor to cool before touching it. Metal parts can be very hot.

E16 often indicates that the system is overheating and a protection circuit has been triggered.

• Check installation: Ensure there is adequate ventilation around the wine cooler, especially at the rear and sides. Follow De Dietrich clearance recommendations.
• Clean the condenser: Remove the rear lower panel and use a soft brush and vacuum to remove dust from the condenser coil.
• Verify condenser fan operation: Spin the fan by hand and check for free movement. Replace the fan motor if it is seized or noisy.
• Inspect for obstructions: Make sure nothing is blocking the air intake or exhaust grilles.
• Allow cool-down: Leave the unit unplugged for at least 30–60 minutes to allow the compressor's internal overload to reset.
• Restart and monitor: Plug the unit back in and monitor compressor temperature and operation. If E16 returns quickly despite good airflow, the compressor may be failing and should be evaluated by a professional.
