Klarstein coffee maker makes loud gurgling or banging noises during brewing.

Safety first: Keep hands away from hot surfaces and steam vents. Unplug before opening covers.

User actions:

• Ensure the water tank is filled above the minimum mark.
• Run a full descaling cycle to remove scale that can cause noisy boiling.
• After descaling, run two full tanks of clean water to flush air and residue.

Internal checks (advanced):

• Inspect silicone hoses for kinks or loose routing that may cause vibration against the housing.
• Secure hoses with clips or cable ties as needed.
