Wine cooler produces a gurgling or hissing sound during operation.

Note: Gurgling and light hissing are usually normal sounds for Blomberg wine coolers.

• Verify operation: Ensure the unit is cooling properly and there are no error codes or performance issues.
• Check installation: Make sure the cooler is level and not touching cabinets or walls that can amplify noise.
• Monitor over time: If the sounds become significantly louder or are accompanied by loss of cooling, contact a technician to check for refrigerant issues.
