Breville Barista Express BES870XL: problems, parts and running costs

Checked: 2026-10-05

Summary

The brewer side of the BES870XL is well regarded, but the integrated grinder is the weak spot and 2019-2022 units can develop group-head leaks from a collar-screw defect. Running costs are beans, milk, descaling supplies and water filter cartridges; there is no pod or capsule lock-in. At $499.95 (Breville US, October 2026) it is the cheapest Breville with an integrated grinder and a defensible buy; at the $699.95 list price it is harder to recommend.

Common problems and fixes

Grinder jams and motor failure — a recurring fault: r/espresso calls the grinder “definitely a weak spot” with tolerances below dedicated grinders, and a home-barista thread documents a jam followed by flashing indicator lights and a non-functional machine; a separate thread asks about repairing the grinder’s electric motor. Workaround: upper and lower burrs are removable for cleaning, and Breville sells replacement parts through its parts channel; a parts supplier states the machine comes with a 2-year warranty, and Breville’s warranty page voids coverage for units not bought from Breville or an authorized reseller. [7][8][2][9][4]
Group-head leaks on 2019-2022 units — a parts supplier documents that the five collar screws holding the group-head collar were fitted without threadlocker, so vibration and pressure loosen them and cause leaks; the repair requires disassembly of over 80% of the machine. A separate case kept leaking even after an official gasket replacement. Fix: Breville is aware and treats this as a manufacturing defect honoured under the 2-year warranty. [9][10]
No low-water warning — Tom’s Guide flags that the tank can run dry with no alert, a practical risk for buyers. Workaround: refill the 2 L tank before each session; the machine has a CLEAN/DESCALE indicator light but no low-water alert. [5][3]
Breaker tripping and PCB damage — one forum owner reports the machine tripping the mains breaker when a brew button is pressed, with the cause unresolved; a Reddit thread documents PCB and main-board damage after a voltage spike. No documented fix; repairs centre on the main board and solenoids. Warranty coverage for this fault is not documented. [11][12]
Fingerprints and grounds buildup — the stainless body shows fingerprints quickly and grounds collect around the portafilter area. Workaround: wipe the body after use; the drip tray is removable for cleaning. [5][3]
Learning curve — reviewers state the machine is not automatic and requires technique and know-how; shots improve with practice and dialing in. Workaround: use the Razor trim tool and dosing funnel that ship in the box. [5][6][1]

Parts and consumables

Water filter — replaceable cartridge for the 2 L tank; a specialist reviewer advises changing it more often than the machine asks. Breville sells replacements through its parts hub. No price reported. [6][2]
Cleaning tablets and descale powder — ship with the machine; Breville’s hub documents the cleaning cycle and descale procedure. No price reported. [1][2]
Group gasket — third-party silicone gaskets are sold for the exact model; the documented collar-screw repair needs near-full disassembly. No price reported. [9]
Conical burrs — upper and lower burrs are removable for cleaning; replacements are available through Breville’s parts channel. No price reported. [3][2]

Yearly running cost

Not enough data. The machine has no pod or capsule lock-in; the ongoing costs are beans, milk, descaling supplies and water filter cartridges, and Breville includes an initial supply of cleaning tablets and a filter. No owner-reported annual total exists in the research. [1][2]

When it is a good buy

$499.95 (Breville US, October 2026) — the cheapest Breville with an integrated grinder; a defensible buy if you want one machine and are willing to maintain it. [1]
$549.95 (Breville US, October 2026) — the BES870CBXL variant; the premium buys a colour or variant, not features. Compare against the $499.95 SKU before paying it. [13]
$649.95 (Breville US, October 2026) — the Barista Express Impress BES876; at this tier compare it for assisted tamping and dose correction rather than defaulting to the older model. [14]
Budget or small counter — Tom’s Guide points budget-limited or space-limited shoppers to the Bambino Plus. [5]
