How to Fix / Troubleshooting

Safety: Unplug the machine before moving it.

  • Descale: Perform a full descaling cycle to reduce pressure-related noise.
  • Check placement: Move the machine to a different surface (e.g., wooden countertop) and test if noise reduces.
  • Inspect feet: Confirm that all rubber feet are present and not hardened or worn.

If noise remains abnormally high, the pump or internal mounts may be worn and require replacement.
