A dripping steam wand is water finding its way through a valve that should be closed. The fix is usually a clean, a seal, or a knob adjustment, in that order.
A closed wand that still drips points at the valve or its seal.The Direct Answer: Find the Drip's Source
If the wand drips when it is off, check three things in order: whether the valve is actually closed (some knobs need a final quarter turn or a clicked position), whether scale is blocking the valve from seating, and whether a seal is worn. Most drips stop at step one or two; the rest are a seal replacement. If the drip comes from the base of the wand rather than the tip, that is a different seal, so look where the water appears before ordering parts.
Why Wands Drip
The wand has a valve that closes off the boiler. When it drips, the valve is not fully sealing, and the causes are predictable: a knob or lever that did not fully close, mineral scale wedged on the seat, a worn or swollen seal, or a valve that needs lubrication. Water can also collect in the wand and drain out after steaming, which is normal; a true drip is steady and continuous, not a single release after purging.
The Check Order
Work through these before opening anything:
- Close the valve fully and confirm it seats; some knobs need a firm click.
- Purge the wand and wait a minute; one-time drainage is normal.
- If it still drips, run a descale, because scale can hold the valve open.
- Inspect the valve area and seals per the manual.
Two of these are free, and descaling fixes more drips than parts do.
The seal, not the whole machine, is usually the leak.Cleaning the Valve
If scale is the suspect, clean the wand and valve path: soak the removable tip in the recommended cleaning solution, wipe the valve seat, and purge thoroughly. If the machine has a hot water or steam cleaning cycle, run it. Do not force the valve open to scrub it; many designs are serviceable only with the correct tool, and forcing them breaks the seat.
Replacing the Seal
When cleaning does not help, the seal is likely worn:
- Order the correct seal for your model; a mismatched size will not hold.
- Remove the old seal without scratching the valve seat.
- Install the new one per the manual and close the valve gently.
If the wand base leaks during use rather than dripping when off, replace the base seal instead; the two seals fail for the same reasons but at different spots.
Preventing the Next Drip
Prevention is mostly routine: purge the wand for a second after steaming so milk does not dry in the tip, close the valve fully and deliberately, descale on schedule, and do not leave the wand buried in milk while hot. These habits keep scale and wear away from the seat, which is where drips are born.
Edge Cases and What to Try Next
If the drip only happens after the machine has been off for a while, it may be expansion draining back through the wand, which is normal in some designs. If the wand hisses while closed, the seal is failing under pressure, not just at rest; replace it before it becomes a spray. And if the drip tray fills under the machine but the wand looks dry, trace the water to the tray hose or a loose fitting inside; that is a different leak entirely.

FAQ
Why is my steam wand dripping water?
A drip when the wand is off usually means a worn seal, a valve seat that no longer closes fully, or scale on the valve. Check the knob or lever adjustment first, then clean the valve, and replace the seal if the drip persists.
Why is my Breville steam wand leaking?
On Breville machines, leaks at the wand base or steam tip usually trace to a worn steam wand seal or a valve that needs cleaning after heavy use. Purge the wand regularly and replace the seal with the correct part when the leak appears.
Why is my espresso machine dripping water?
Drips can come from many places: the group, the wand, the drip tray hose, or a loose internal fitting. Find where the water appears, then check that specific seal: group drips point to the gasket, wand drips to the valve, and tray drips to the hose or drip tube.
How do I stop my steam iron from leaking water?
For a steam iron, leaks usually mean water left in the tank, a cooler-than-needed temperature, or mineral scale blocking the steam path. Empty the tank, set the right heat, and descale per the manual; the fix is similar in spirit to an espresso wand: remove buildup and keep seals clean.
