Coffee maker makes loud gurgling or sputtering noises during brewing.

Safety first: Keep hands away from steam vents during operation.

• Check water level: Ensure the reservoir is filled to at least the minimum mark before brewing.
• Descale: Run a full descale cycle with a 1:1 vinegar-water solution to remove scale that can cause noisy boiling and sputtering.
• Inspect reservoir seating: Make sure the reservoir is properly seated so the intake tube is fully submerged.
• Observe for leaks: During brewing, look for water leaking under the unit, which may indicate a cracked tube.
• Normal vs abnormal: Some gurgling at the end of the cycle is normal. Excessively loud or continuous sputtering after descaling may indicate internal tubing issues that require service.
