Wine cooler makes a gurgling or hissing noise that seems unusual to the user.

Safety: No disassembly is required for this check. Do not attempt to open the sealed system.

Many De Dietrich wine coolers produce gentle gurgling or hissing sounds as part of normal operation.

• Observe pattern: If the noise occurs mainly when the compressor starts or stops and is not excessively loud, it is likely normal.
• Check installation: Ensure the unit is level and not touching cabinets or walls that can amplify sound.
• Monitor performance: If temperatures are stable and there are no error codes, the noise is probably not a fault.
• Seek service if in doubt: If the noise is very loud, metallic, or accompanied by poor cooling, have a technician inspect the system.
