Breville is the most common brand we repair in our Melbourne workshop. The Barista Express, Barista Pro, Barista Touch, Oracle and Dual Boiler are great machines, but they share a handful of faults that come up again and again. Here are the most common ones, what causes them and how they get fixed.
1. Low or no pressure
What you notice: the pressure gauge barely moves, coffee drips out slowly or the shot is thin and sour.
Why it happens: scale blocking the thermocoil or solenoid valve, a worn pump, or a grind that’s too coarse because the grinder burrs are worn.
The fix: first try a finer grind and fresh beans. If that doesn’t help, the machine usually needs the waterways descaled, the 3-way solenoid valve serviced and the pump tested.
2. Leaking from the group head or under the machine
Why it happens: the group gasket hardens with heat and age, so water escapes around the portafilter. Water under the machine usually means an internal leak from a cracked hose, a worn o-ring or the pump.
The fix: a new group gasket and shower screen fixes most group leaks. Internal leaks need to be found and fixed quickly, because water dripping onto the control board can turn a small repair into a big one.
3. Grinder jammed or not grinding
Why it happens: oily beans clog the burrs and chute, or a small stone in the beans jams or chips the burrs.
The fix: unplug the machine, empty the hopper and clean the upper burr and chute. If it still hums without grinding, the burrs or grinder motor need attention.
4. Weak steam or no hot water
Why it happens: a blocked steam tip, scale in the steam thermocoil or a faulty steam solenoid.
The fix: clean the steam tip with the pin tool after every use. If steam is still weak, the steam circuit needs descaling and the valve checked.
5. Stuck in a cleaning or descale cycle
Why it happens: the cycle was interrupted, or scale stopped water flowing properly so the machine can’t finish.
The fix: try a reset following the manual. If the cycle still won’t finish, the waterways need clearing in the workshop.
6. Tripping the power or not turning on
Why it happens: usually water reaching an electrical part, a failed heating element or a blown thermal fuse.
The fix: stop using the machine and unplug it. This one isn’t a DIY job. We find where the water came from and fix that as well as the electrical fault, so it doesn’t happen again.
How to prevent Breville problems
- Use filtered water and change the filter every 2 to 3 months
- Descale when the machine asks you to
- Run a cleaning cycle and wipe the group gasket regularly
- Get a full service once a year
