Machine is very noisy during brewing, with rattling or vibration sounds.

Safety: Unplug before opening the housing.

• Check installation: Ensure the machine is on a stable, level surface and not touching walls or cabinets.
• Inspect pump mounts: Open the housing and verify the pump is seated in its rubber mounts and not contacting the chassis directly.
• Secure hoses: Re-route or secure hoses with clips so they do not vibrate against panels.
• Tighten screws: Check and tighten any loose chassis or panel screws.
