The correct Breville Barista Express replacement part must match more than the machine’s 54mm size. Before ordering, match the BES870 or BES870XL model, the U.S. market, the production or batch-code cutoff shown in the listing, the finish where relevant and the exact part number. A part that looks identical—or fits another 54mm Breville machine—may still be the wrong revision.
Most owners can safely replace removable external items such as the portafilter, filter baskets, bean hopper and lid, water tank, water-filter holder, drip-tray pieces, loose accessories and certain parts specifically covered by the BES870 manual. Pumps, solenoid valves, thermocoils, control boards, internal hoses, wiring and other pressure or electrical components belong with Breville or an authorized service provider.
Before you buy: Photograph the machine label and the old part, copy every model, batch/PDC and part-number marking exactly, and require the replacement listing to name BES870 or BES870XL. Do not use “for Breville,” “Barista Express” or “54mm” alone as proof of fit.

This guide is for the Barista Express BES870 series, including the BES870XL sold in the United States. It does not treat the Barista Express Impress BES876, Barista Pro BES878 or Barista Touch BES880 as interchangeable models. Some loose tools and baskets may be shared across machines, but compatibility must be confirmed for the exact part rather than assumed from the product family.
This BES870XL parts list focuses on the replacement parts most useful to owners rather than reproducing every internal component shown in a service diagram. It covers removable brewing, grinder, water-tank, drip-tray, steam-wand and group-head parts, plus the compatibility checks that matter before ordering.
Identify the exact Barista Express before searching for parts
The product name on the front is not enough. Breville parts listings can divide one model by production revision, finish or market. Start with the rating label, which is normally underneath or on the back of the appliance, and record the information before moving the machine.
- Model: Copy the full code, including any suffix shown on the label. A U.S. retail page may call the machine BES870XL while the manual covers the BES870 series.
- Batch, production or PDC information: Copy the code exactly. Do not guess a date from it or round it to a nearby number.
- Serial number: Keep it available when asking Breville to confirm a part or a superseded reference.
- Country of purchase: This article uses the United States machine and catalog as its baseline. A similar-looking part from another market may belong to a different electrical or production specification.
- Color and finish: Record whether the machine is brushed stainless steel, Black Sesame, Cranberry or another finish. Tanks, drip-tray guards and cosmetic pieces may be finish-specific.
Unplug the machine, allow it to cool and empty the water tank and drip tray before tilting it to read a label. Take a clear photo so you do not have to move the machine again while comparing listings.
How to verify a Breville part number
A reliable match starts with the machine, moves to Breville’s current U.S. catalog and only then moves to a retailer. Reversing that order makes it easy to accept a keyword-filled marketplace title that does not match the actual compatibility data.
- Select the BES870 product family in the current U.S. parts catalog.
- Find the precise component name, not merely the machine area. For example, the drip tray can include a cover, grille, float, separator and storage tray.
- Copy the current Breville product code and complete product title. Keep any words such as “pre,” “from,” a PDC value, color or finish.
- Check the listing’s compatible-machine information against the model label. If the catalog does not clearly include the BES870/BES870XL revision you own, ask Breville before ordering.
- Compare the old component’s molded number, markings, attachment points and finish with the official product images. A visual match supports the part-number check but does not replace it.
- When buying elsewhere, require the same exact part number and revision in the specification section. Check the return policy before opening or installing the item.
Production cutoffs are not theoretical. Breville’s U.S. catalog currently separates some BES870 water-tank assemblies with “From 1708F PDC” wording, while upper burrs are divided into pre-1926 and from-1926 versions. Those examples show why “fits the Barista Express” is not a complete compatibility statement.
54mm portafilter and filter-basket replacements
The BES870XL uses a nominal 54mm brewing system, but a complete portafilter also depends on the body diameter, locking-lug shape, lug position and handle clearance. A portafilter made for another 54mm machine can fail to lock correctly even if one of its baskets has a similar diameter.
If you are replacing only a basket, identify both its cup capacity and wall design:
- 1 CUP Single Wall: The smaller non-pressurized basket for freshly ground coffee.
- 2 CUP Single Wall: The larger non-pressurized basket most owners use when dialing in fresh beans.
- 1 CUP Dual Wall: The smaller pressurized basket, commonly used with pre-ground coffee.
- 2 CUP Dual Wall: The larger pressurized basket. Its restricted outlet creates resistance differently from a Single Wall basket.
Do not replace a basket solely because a shot runs too quickly or slowly. First make sure its holes are clean and separate the basket from grind, dose and tamping variables. The Breville Barista Express settings guide explains the correct basket choice and normal dial-in, while the BES870XL pressure troubleshooting guide covers abnormal gauge behavior and flow.
Replace a portafilter when the handle, body, spouts or locking lugs are physically damaged or the correct assembly is missing. If coffee leaks around an undamaged portafilter, inspect puck height, a dirty rim and the group-head seal before assuming the complete portafilter has failed.
Bean hopper, lid and upper-burr replacements
The removable bean hopper and its lid are separate parts. Replace the hopper if it is cracked, its locking interface is damaged or it no longer seats securely; replace only the lid if the lid is the missing or broken component. The grinder will not operate normally unless the hopper is correctly locked, so a seating problem should be checked before any internal grinder part is ordered.
The removable upper burr is also revision-sensitive. Current catalog wording separates an earlier upper-burr assembly from an Etzinger version used from a later PDC. Match the machine’s code to the listing rather than choosing the newer-looking part or assuming it is an upgrade.
- Clean the accessible grinder and rule out an obstruction before deciding a burr is worn or defective.
- Photograph the installed upper burr, including its adjustment markings and molded details.
- Do not mix pre- and from-PDC versions unless Breville confirms a superseding part for your serial or batch.
- Treat the motor, wiring, gearbox and other enclosed grinder components as service parts rather than speculative purchases.
A silent grinder, a motor that runs without dispensing, a jam or a new loud noise requires diagnosis before shopping. Follow the Barista Express grinder fault guide so a blocked chute, unlocked hopper or moisture problem is not mistaken for a failed replacement part.
Water tank, filter holder and water-filter replacements
The U.S. BES870 manual describes a removable 67 fl.oz (2-liter) water tank with a replaceable filter. The tank assembly, filter holder and filter are different products: a spent filter does not require a new tank, and a cracked tank does not automatically require a new holder.
| Part | Replace it when | Check before ordering |
|---|---|---|
| Water-tank assembly | The tank is cracked, leaking from damaged plastic, missing or has a broken integral feature | Model, finish/color, production cutoff and complete assembly contents |
| Water-filter holder | The reusable holder is missing, cracked or will not retain the correct filter | Exact holder design for the machine and filter family |
| Water filter | The consumable reaches its replacement interval or the machine’s maintenance plan requires it | Compatibility with both the holder and the BES870 batch |
If an intact tank does not feed water, push it fully into position and diagnose the water path before buying another tank. The Breville Barista Express water-flow guide separates tank seating, air, scale and accessible blockages from faults that require service.
Do not repair a food-water tank with an unknown adhesive or coating. A patch can fail, contaminate the water or interfere with the tank’s seating interface. Replace a genuinely cracked assembly with the verified part instead.
Water-filter replacement and descaling are maintenance tasks, not interchangeable fixes. Use the complete BES870 cleaning and descaling guide for the filter schedule and correct procedures rather than adding those instructions to a parts order.
Drip-tray and storage-tray parts
“Drip tray” can describe the whole removable section or one of several individual pieces. Identify what is actually broken or missing before ordering a complete assembly. Depending on the production version and finish, the parts catalog may separate the tray cover, metal grille, floating full indicator, coffee separator, storage tray and a guard supplied with colored machines.
- Grille or grid: The top surface that supports the cup.
- Cover or lid: A shaped tray component beneath or around the grille; do not assume every seller uses the same naming.
- Float or full indicator: The removable indicator that rises when the tray fills.
- Coffee separator: The internal piece that keeps wet grounds apart from part of the tray.
- Storage tray: The separate compartment located behind the drip tray.
- Color-model guard: A finish-related loose piece that should not be discarded simply because a stainless model does not show the same item.
Water in the tray does not by itself prove that a tray or internal valve has failed. The machine normally purges some water into the drip tray after espresso, hot-water and steam functions. Replace a tray component for physical damage or poor fit, not merely because the tray collects water as designed.
Compare the old component from above, below and at every clip or latch. Cosmetic pieces deserve the same finish check as a water tank; a functional fit can still leave a visibly mismatched machine.
Steam-wand tip and external steam parts
The U.S. BES870 manual treats the removable steam-wand tip as an owner-accessible cleaning point. A missing, cracked or damaged tip can be replaced when the exact thread and model compatibility are confirmed. The cleaning tool is also a separate loose item and includes the pin and integrated spanner used for the documented tip care.
A blocked tip should be cleaned before it is condemned. If the machine produces no steam or weak steam, use the BES870 steam-wand troubleshooting guide to distinguish normal heat-up, a blocked removable tip, scale and a service-level fault.
Stop at the external boundary. A leak from inside the machine, a failed steam valve, damaged internal tubing, an electrical symptom or a complete wand-pivot repair is not made safe by finding a similarly named part online. The steam and water systems operate hot and under pressure; those repairs belong with Breville or an authorized servicer.
Group-head silicone seal and shower screen
The silicone seal around the shower screen is a genuine wear item. A seal can become relevant when a correctly loaded, undamaged portafilter no longer secures properly or water escapes around the group-head rim. Coffee on the basket rim, an excessive dose and incorrect locking can produce similar symptoms, so confirm those simpler causes first.
Breville’s BES870 manual documents removal of the retaining screw and shower screen with the supplied Allen key, replacement of the silicone seal and reassembly without overtightening. Use the exact current manual and the correct seal for the machine. The unit must be switched off, unplugged and cool before this work.
This documented seal procedure does not make the entire group head owner-serviceable. If the screw is seized, the casting is damaged, the new correct seal does not restore fit or the leak comes from inside the housing, stop and request service rather than extending the repair into valves, hoses or the thermocoil.
Replace lost original tools without buying an unnecessary bundle
The current U.S. Barista Express package includes several loose items that can disappear when a used machine changes hands: a dosing funnel, integrated removable tamper, stainless-steel milk jug, Razor dose-trimming tool, cleaning disc, cleaning tool, brush, Allen key, filter holder and initial filter. A missing item is a replacement need, but it does not justify buying every piece again.
| Missing item | Most direct replacement decision | Do not confuse it with |
|---|---|---|
| Dosing funnel | Replace with the original or a version explicitly fitted to the BES870 54mm portafilter | A generic ring that does not lock or clears neither the grinder cradle nor tamper |
| Tamper | Replace with a BES870-basket-compatible size | A nominal 54mm tool whose actual base binds in the basket |
| Razor tool | Replace only if you use the supplied dose-height check | A distributor or other puck-preparation accessory |
| Cleaning disc | Use the 54mm disc intended for the documented cleaning cycle | A filter basket or a blind part for a different portafilter system |
| Cleaning tool | Replace the model-appropriate pin/spanner tool | Improvised wire that can enlarge a steam-tip or basket opening |
| Milk jug | Any replacement must be food-safe and sized for the milk volume | A machine-specific repair part; the jug does not fix weak steam |
If the original part is present and functional but you want better measurement, puck preparation or workflow, that is an upgrade decision. The Breville Barista Express accessories guide explains what is worth buying, what the BES870XL already includes and which 54mm claims need additional checks.
Parts that should go to Breville or an authorized servicer
Availability online does not make a component owner-serviceable. The BES870 manual directs maintenance other than cleaning to Breville Consumer Support. Keep the following items outside a normal do-it-yourself parts order unless Breville has diagnosed the machine and arranged qualified service.
| Service-level component | Why not to buy it speculatively | Better next action |
|---|---|---|
| Pump | No water, noise or pressure symptoms can also come from the tank, air, scale, puck resistance or another valve | Complete the safe external diagnosis, then request service |
| Solenoid or internal valve | It is part of a hot, pressurized water system and cannot be diagnosed by appearance | Have the flow and leak path professionally identified |
| Thermocoil, heater or thermal protection | Electrical and high-temperature work creates shock, fire and burn risks | Stop using an overheating or non-heating machine and contact service |
| Control board, switches or internal wiring | Similar symptoms may have different electrical causes; the correct regional board also matters | Use qualified electrical diagnosis |
| Power cord or plug | A damaged grounded supply cord is a safety fault, not a cosmetic replacement | Stop using the machine and arrange authorized repair |
| Grinder motor, enclosed drive parts or wiring | A blockage, moisture or a removable-part problem can mimic motor failure | Follow the grinder diagnostic owner, then service if unresolved |
| Pressure gauge or internal tubing | Gauge position alone does not identify the failed component, and internal fittings carry hot water | Compare gauge behavior with actual flow, then request service if the machine-side fault remains |
| Steam valve, internal wand joint or tubing | Steam is hot and pressurized, and a housing leak can worsen suddenly | Stop using the steam function and arrange service |
If the symptom does not clearly point to a damaged removable part, start with the complete Barista Express BES870 troubleshooting guide. It routes the problem to pressure, steam, grinder, water-flow or maintenance checks without turning a parts list into an unsafe repair manual.
OEM versus aftermarket BES870XL parts
A genuine Breville part is the simplest reference point for restoring an original component, especially when a PDC cutoff, molded interface, food-contact surface or matching finish matters. A third-party replacement can still be reasonable, but its seller must prove compatibility rather than merely place popular model names in the title.
| Check | Genuine/OEM part | Third-party part |
|---|---|---|
| Model fit | Confirm the official listing includes the exact BES870 revision | Require BES870/BES870XL in the detailed compatibility data, not only the title |
| Part number | Use the current Breville code and any supersession information | Require a direct cross-reference to that exact code |
| PDC or batch cutoff | Follow the stated pre/from cutoff | Reject a universal claim that ignores a known cutoff |
| Food and water contact | Use the specified component and care instructions | Require suitable materials, intact surfaces and credible documentation |
| Finish | Choose the listed machine color or finish | Compare actual photos and color; names such as “stainless” do not guarantee a visual match |
| Returns | Check Breville’s current parts-return terms | Prefer a seller that accepts a clean, uninstalled mismatch |
Used parts make the most sense for cleanable, non-electrical external pieces whose condition can be inspected. Avoid a used cracked water component, worn seal, damaged basket, corroded food-contact part or untested electrical assembly. A low price does not compensate for an uncertain revision or hidden wear.
What to do when the correct part is out of stock
Do not move to the nearest-looking part as soon as the verified item is unavailable. Preserve the identification work and use the exact reference to look for a safe alternative.
- Save the official product title, part number, PDC wording and compatibility details.
- Use the manufacturer’s stock notification if one is offered.
- Contact Breville with the machine model, batch/PDC and serial number and ask whether the part has a superseding reference.
- Ask an authorized servicer whether it can supply or install the confirmed component.
- If shopping through another retailer, search the exact part number and verify that the delivered package carries the same reference before installation.
A seller’s claim that one part “replaces all previous versions” needs confirmation when Breville itself separates the catalog by production cutoff. Do not solve an availability problem by creating a compatibility problem.
Final pre-order checklist
- I have a clear photo of the machine’s model and serial/batch label.
- The part is listed for the U.S. BES870/BES870XL revision I own.
- I copied the exact part number rather than relying on the product name or photo.
- I checked every pre/from-PDC or batch-code condition.
- The finish, color, attachment points and included subparts match what I need.
- If it is a basket, I selected 1 CUP or 2 CUP and Single Wall or Dual Wall intentionally.
- If it touches coffee or water, its materials and condition are suitable for that use.
- I ruled out cleaning, seating, settings or an accessible blockage before labeling the old part defective.
- The work stays within the external or manual-documented owner boundary.
- I checked the seller’s return terms before opening or installing the part.
Breville Barista Express replacement-parts FAQs
Are BES870 and BES870XL parts the same?
BES870 is the series identifier used in current documentation, while U.S. retail listings commonly show BES870XL for the Barista Express. That does not mean every part sold under either term fits every production revision. Use the full model label, batch/PDC and official part compatibility for the individual machine.
Do all Breville 54mm portafilters fit the BES870XL?
No. The basket diameter is only one measurement. A complete portafilter must also have locking lugs, lug positions, body dimensions and handle clearance compatible with the BES870/BES870XL group head. Require an explicit model listing.
Will a Barista Express Impress BES876 part fit the BES870XL?
Do not assume it will. Some loose 54mm baskets or tools may be listed for both machines, but machine-mounted components can differ. Buy the part only if its current compatibility data explicitly includes the BES870/BES870XL revision you own.
Where is the model or serial number on a Barista Express?
Breville advises looking for the identification label underneath or on the back of the product. Switch the machine off, unplug it, let it cool and empty removable water before moving it. Photograph the full label so the model, batch and serial information remain together.
What does a pre- or from-PDC note mean on a Breville part?
It marks a production cutoff used to separate component revisions. Copy the code from the machine label and compare it with the exact listing. If the label and cutoff are not clear, give Breville the model and serial number rather than guessing which side of the cutoff applies.
Can I replace the upper burr myself?
The upper burr is removable in the manual’s grinder-cleaning process, but the replacement itself must match the machine’s production revision. Clean and diagnose the accessible grinder first, unplug the machine, treat the burr edges as sharp and do not extend the job into the motor, wiring or enclosed drive system.
Can I replace the group-head silicone seal?
The U.S. BES870 manual documents replacement of the silicone seal behind the shower screen with the supplied Allen key. Use the exact seal and current procedure, with the machine off, unplugged and cool. If the screw, screen, casting or internal leak does not match that documented task, use service instead.
Does water in the drip tray mean I need a replacement valve?
Not by itself. The Barista Express normally purges water into the drip tray after espresso, hot-water and steam use. A tray that fills unusually fast, leaks outside the machine or receives water at unexpected times needs diagnosis, but normal purge water is not proof of valve failure.
Where should I buy BES870XL replacement parts?
Start with Breville’s current U.S. BES870 catalog to identify the exact product code and revision. Buying directly is one option; another retailer is reasonable only when it supplies the same verified reference, clear compatibility details and acceptable return terms. Do not buy from a marketplace title alone.
Should I replace a part when cleaning does not immediately fix the symptom?
Not automatically. A persistent symptom can come from settings, water delivery, a different component or a service-level fault. Use the appropriate diagnostic guide and replace a removable part only when damage, wear, missing hardware or a confirmed diagnosis supports that decision.
Order by identity, not by appearance
The safest purchase path is simple: identify the exact U.S. BES870/BES870XL machine, find the current official component, preserve its full part number and revision notes, and require any seller to match them. That process matters most for water tanks, upper burrs, complete portafilters, seals and finish-specific pieces, where a close visual match can hide an important difference.
Replace external originals when they are missing, damaged or confirmed worn. Use the accessories guide when the goal is an upgrade, the maintenance guide when the real need is cleaning, and the troubleshooting hub when the machine has a symptom rather than an identified broken part. Keep internal electrical, hot-water and pressurized-system work with qualified service.
