If you see steam coming from the bottom of a Breville Barista Pro, first determine exactly where it is coming from. Steam or condensation around the drip tray during or just after steaming can be part of normal purging. Steam escaping from the base, side panels, or cabinet seams is different and should be treated as a possible internal leak.
Quick diagnosis
| Where the steam appears | What it may mean | What to do |
|---|---|---|
| Over the drip tray after steaming | Normal purge/condensation may be visible | Empty tray and observe |
| From steam wand tip | Normal during steaming or purge | Clean and purge wand |
| From underneath the cabinet | Possible internal steam/water leak | Stop use and inspect externally |
| From a side or rear seam | Possible hose, fitting, valve, or seal leak | Unplug and arrange service |
When steam near the bottom can be normal
The Barista Pro is designed to purge the steam wand over the drip tray. Breville recommends positioning the wand over the tray before and after milk texturing and purging it for a few seconds. Hot condensate entering the tray can create visible vapor.
The machine also makes a pumping noise while producing steam; Breville identifies this as normal operation.
If the vapor appears only above the drip tray, stops shortly after steaming, and there is no water collecting beneath the machine, start by emptying and cleaning the tray rather than assuming there is an internal failure.
Steam from the cabinet or base is not normal
If steam is visibly escaping from underneath the machine body, from a cabinet seam, or from somewhere other than the steam wand and drip-tray area, switch the machine off and unplug it.
An internal steam leak can involve hot pressurized water. Do not continue repeatedly steaming milk to “test” the fault and do not remove the machine casing unless you are qualified to service espresso equipment.
1. Empty and correctly seat the drip tray
A full or poorly seated drip tray can make normal purge water look like a leak. Remove the tray, empty it, wash and dry the parts, then push it fully back into position.
Run the machine again while watching whether the vapor is actually rising from the tray or escaping from beneath the chassis.
2. Clean and purge the steam wand
A blocked steam tip reduces frothing performance and can create irregular steam behavior, although it should not normally cause steam to escape through the machine base.
Breville recommends wiping the wand after milk texturing and purging it for a couple of seconds. If the tip hole is blocked, use the supplied steam-wand cleaning tool. If necessary, remove and soak the tip according to the machine instructions.
3. Check the water tank and normal water flow
Make sure the water tank is filled and seated correctly. Then test the hot-water function and a normal espresso water flow.
If steam from the cabinet is accompanied by unusually weak water flow, repeated refill messages, or water accumulating under the machine, stop using it and arrange service.
4. Descale only when the machine actually needs it
Scale can reduce flow and steam performance, and the Barista Pro has a dedicated three-stage descale cycle for the coffee, hot-water and steam circuits. Use the DESCALE function when the machine requests it rather than running an improvised cleaning solution.
Descaling can improve restricted flow, but it is not a repair for a leaking internal hose, valve, fitting, or seal.
For the general maintenance distinction, see our Breville descaling guide.
What about a group-head gasket?
A worn group-head seal usually causes water to escape around the portafilter during extraction. That is different from steam emerging from underneath the machine.
If the leak occurs around the portafilter only while brewing, investigate the group-head seal and basket rim. If steam comes from inside the cabinet during steam use, the fault is likely elsewhere.
When professional repair is the right next step
Stop using the machine and contact Breville or a qualified repair technician if:
- Steam comes from the base or cabinet seams.
- Water collects underneath the machine.
- You hear hissing inside the cabinet after the steam dial is returned to standby.
- The machine trips power, smells hot, or shows an error.
- The problem continues after the drip tray and steam wand have been cleaned.

FAQ
Is steam above the Barista Pro drip tray normal?
A small amount of vapor can be normal when hot purge water or condensation enters the drip tray after steaming.
Is steam coming from underneath the machine normal?
No. Steam escaping from the cabinet or base should be treated as a possible internal leak. Switch the machine off and arrange inspection rather than continuing to use it.
Can a blocked steam wand cause this?
A blocked tip can reduce steam performance and should be cleaned, but visible steam escaping through the machine body points to a different problem.
Will descaling fix a steam leak?
Descaling can restore flow affected by mineral buildup. It cannot repair a damaged internal seal, hose, fitting or valve.
