Gurgling or sputtering noises are unusually loud during brewing

Safety: Hot water and steam can cause burns; keep hands away from outlet arm during brewing.

• Check water level: Always fill the reservoir to the intended brew volume; avoid running the boiler nearly dry.
• Descale: Perform a full descaling cycle to remove scale that can cause noisy boiling and sputtering.
• Inspect hoses (advanced): Remove the base and check that all silicone hoses are firmly attached and not cracked. Replace any that appear hardened or loose.
• Test after service: Reassemble and run a test brew. Some gurgling is normal, but excessively loud sputtering should be reduced.
