The most common causes include a full drip tray, loose water tank, worn seals, blocked drainage channels or internal leaks. The location of the water often provides the first clue as to what's causing the problem.

Yes. Most automatic coffee machines direct rinse water and pressure relief water into the drip tray during normal operation. Small amounts of water are expected, but if the tray fills unusually quickly or water leaks onto the worktop, further investigation is worthwhile.

Water underneath the machine may indicate a leaking hose, worn seal, cracked water tank or blocked internal drain. If the leak has appeared suddenly or is getting worse, stop using the machine until you've identified the cause.

Yes. Limescale can restrict the internal water circuit, increasing pressure and contributing to leaks around seals, valves and hose connections. Regular descaling helps reduce the risk of scale-related leaks.

If water is leaking onto your worktop or from inside the machine, it's best to stop using it until you've found the cause. Continuing to use a leaking machine can allow water to reach electrical components or make the fault worse.

Simple issues such as an incorrectly fitted water tank, overfilled drip tray or blocked coffee outlet can often be resolved at home. However, if the leak is coming from inside the machine or continues after basic checks, professional diagnosis may be needed to inspect seals, hoses or internal components.
