We read 114 manufacturer documents across 16 brands looking for one sentence saying a part fits a machine. Not one contains it. Four makers get close and all four stop in the same place.
What the manufacturers actually publish about their espresso machines, and what they do not.
Two of the five espresso brands publish a parts document, and both name their component maker. IMS names Rocket machines by model, publishes every dimension, and still will not say a basket fits one.
The BES870 manual states a Thermocoil heater and the BES878 states Thermojet. The manuals name three differences and state no dimensions or weight for either.
The BES870 Barista Express instruction book states a Thermocoil heater, a 2L tank, a 250g hopper and a 54mm portafilter. It states no dimensions and no weight.
Breville publishes two BES880 instruction books, issue U22 and issue H19. They agree on the components and disagree on how hard to tamp.
The BES878 Barista Pro instruction book states a Thermojet heater, 30 grind settings, a 2L tank and a 54mm portafilter. It states no dimensions and no weight.
Breville hosts instruction books on two different paths. One carries the region and revision in the filename and one carries neither, which decides whether a citation is reproducible.
Breville prints 54mm for both the portafilter and the tamper in its espresso instruction books. It never states that a basket from one model fits another.
De'Longhi manuals carry a consolidated Technical Data block with dimensions, weight and cord length, which is more than any other brand of five publishes.
Gaggia publishes a Classic parts diagram with 90 numbered parts. Its numbers do not map to the newer Evo 12NC scheme and no published document connects them.
De'Longhi states pump pressure in MPa first and bar second. Three model families state 1.5 MPa, two state 1.9 MPa, and no manual says the higher figure brews better coffee.
Gaggia publishes a service manual for the Classic 2019 and Classic Evo Pro, revision 04 dated 25 September 2023. It is the only one of five brands that does.
Gaggia publishes an electrical diagram inside its service manual, revision Rev.04 25/09/2023. The wiring loom is a market-specific part with three named assemblies.
Gaggia's parts diagram lists 22 machine variants across two type codes. The same model number appears three times with three different 12NC codes by region.
The Philips 1200 range contains six model codes and the 2200 contains ten. A specification leaflet was obtained for one of the sixteen, and this page names which.
The Philips 3200 range contains seven model codes and the 3300 contains nine. A leaflet was obtained for one of the sixteen, and this page states which.
A Philips leaflet was obtained for the EP5447/90 in the 5400 range. The declaration lists three model codes in the 5500 range and no leaflet for them was retrieved.
Philips product leaflets list AquaClean filter compatibility on every espresso model checked, and attach a footnote to the 5000 cups figure that bounds it.
Philips publishes specification leaflets for its espresso machines and no parts diagram or part numbers. Its authorised parts distributor could not be read.
A Philips EU declaration lists 67 distinct EP model codes. The 2200 range alone contains ten machines, so a range name does not identify a machine.
Philips leaflets state the milk system per model. LatteGo comes with a 0.26 L carafe, the Classic Milk Frother comes with none, and the weight differs by 0.5 kg.
The Appartamento spare parts catalogue lists 144 part numbers across nine sections. Seven of the parts Rocket sells in its own shop appear in it, under different names.
Rocket publishes 11 parts with manufacturer part numbers on its own shop, readable by every crawler tested. It publishes no parts catalogue, and the official ones are hosted by retailers.
Rocket publishes a specification block for every domestic machine in its own catalogue, with boiler capacity, weight, wattage and dimensions. Eight machines are fully specified.
The authorised Philips parts site returns 403 to all ten user agents tested, including Googlebot and a browser UA, and is named by none of 18 assistant responses.
Five espresso manufacturers were checked for cross-model compatibility, brew temperature and OPV settings. None of the five publishes any of the three.
De'Longhi hosts manuals on its own document server at dls.delonghigroup.com. The URLs carry a language code and a numeric ID, and nothing else.
Five espresso manufacturers were checked for a published serial number format, location or lookup. One publishes all three. The other four publish nothing readable.
