Water underneath the machine can come from several places, including an overflowing drip tray, incorrectly fitted water tank, leaking tank valve, worn seal or an internal hose or connection. Dry the machine and worktop completely first, then observe when the water reappears. Whether it leaks while idle, rinsing or brewing can help narrow down the source.

Yes. A full, damaged or incorrectly fitted drip tray can allow water to escape underneath the machine. Water from rinsing, brewing and pressure release can accumulate in the tray even when relatively few drinks have been prepared. Empty and inspect the tray, refit it correctly and monitor whether the leak returns.

Yes. Check the water tank for cracks, damage around its outlet valve and whether it is correctly seated. A leaking tank valve or connection can allow water to escape continuously, sometimes travelling through the machine before appearing underneath it. If water appears even while the machine is switched off, the tank and its connection are particularly worth checking.

A leak that occurs specifically during brewing may indicate water escaping once the hydraulic system becomes pressurised. Possible causes include worn brewing seals, leaking internal connections, hoses or valves. If the drip tray and water tank remain dry but water appears underneath during every drink, an internal leak becomes more likely.

Water appearing while the machine is switched off often points towards a leak on the water-supply side of the system rather than a pressure-related brewing leak. Check the water tank, outlet valve and tank connection first. If these appear sound but water continues to collect underneath, an internal connection or seal may require investigation.

If the source is simply an overflowing or incorrectly fitted drip tray, correct the problem and monitor the machine. If water appears to be escaping internally or you cannot identify where it is coming from, stop using the machine. Internal leaks can potentially allow water to reach electrical components and should be investigated before further use.
