Water underneath the machine can come from an incorrectly fitted or damaged water tank, overflowing drip tray, leaking internal hose, worn seal or a problem within the internal water circuit. First dry the area completely, then operate the machine briefly to help identify when and where the leak appears.

If the leak appears specifically during brewing, pressure within the water circuit may be exposing a worn seal, loose connection or leaking hose. Check the water tank and drip tray first; if they're dry and correctly fitted, an internal leak may require further diagnosis.

Yes. A damaged tank, leaking outlet valve or incorrectly seated water tank can allow water to escape and run underneath the machine. Remove the tank, inspect it for cracks or damage and check the outlet area before refitting it securely.

A leak that continues while the machine is switched off often points towards the water supply side of the system. The water tank, tank outlet valve, seals or connections between the tank and internal water circuit should be checked for leakage.

Yes. Water produced during rinsing and normal operation is often directed into the drip tray. If the tray is full, incorrectly fitted or the drainage path is obstructed, water may overflow or find another route underneath the machine. Empty, clean and correctly refit the drip tray before testing again.

No. If you've ruled out a full drip tray or incorrectly fitted water tank and water continues appearing underneath the machine, stop using it. An internal leak can allow water to reach electrical components, so the source should be identified and repaired before the machine is used again.
