Coffee maker makes loud gurgling or banging noises during brewing.

Safety first: Keep hands away from hot surfaces and steam vents; unplug before inspection.

• Fill tank fully: Ensure the water tank is filled to the recommended level before brewing to minimize air in the system.
• Descale: Perform a descaling cycle to remove scale that can cause irregular boiling and noise.
• Check placement: Make sure the coffee maker is on a stable, level surface to reduce resonance and vibration noise.
• Inspect hoses (advanced): If accessible, check for kinked or pinched hoses. Straighten gently if found. Persistent loud banging may indicate internal issues requiring service.
