Gaggia E24 review

The area figure matters more than it looks. A wider basket spreads the same dose of coffee into a shallower bed, and a shallower bed is more forgiving of an imperfect tamp and less prone to the water carving a channel straight through it. This is a modest effect, not a transformation, and it will not rescue a bad grind. It is worth one sentence, and it has now had it.

It advertises 9 bar, and that is the more useful number

The E24’s listing files “9 bar” in a structured spec field labelled Output Pressure, and puts “9 Bar Espresso Extractions” in its feature bullets. The CM5418 files “20 bar” in the identically-named field. Same field, two completely different kinds of claim.

Espresso is extracted at about 9 bar. That is the target, not a ceiling and not a compromise. A 20 bar figure describes what a pump can generate at full effort against a closed valve, with no coffee in the path — a specification of the part, not of your coffee. Gaggia is quoting the pressure at the puck. CASABREWS is quoting the pressure at the pump. The bigger number is the less informative one, and we have taken that apart properly on the CM5418’s own page. Every Breville here, incidentally, publishes no bar figure at all.

The feature list names a commercial three-way solenoid valve, which is the component that dumps the pressure left in the group head into the drip tray the moment the shot ends. The practical consequence is a puck that knocks out dry instead of collapsing into sludge. It is a small mechanical courtesy and it is the sort of thing that only ever appears on machines built to commercial fittings.

The spec sheet, and what is missing from it

The heating row is the honest embarrassment of this category. None of these three listings names a heating system. The E24’s uses the word “boiler” exactly once, inside a sentence about an updated component that better resists scale and corrosion, and never says which kind. That is not enough to print as a spec, so we have not. Heating is the single most consequential thing about a home espresso machine — it decides how fast you can start, how stable the shot is, and whether you can brew straight after steaming — and most of the market will not tell you.

The water tank is the same story from the other direction. The listing’s structured Capacity field reads “2.1 liters”, which is a plausible number, and we are still not going to print it. That field returns “2.1 pounds” for the CASABREWS and “1 cups” for the Barista Express (BES870XL). A field that unreliable does not become reliable because this time the answer looks sensible.

What the listing does state cleanly: 1200 watts, a brushed stainless housing described as “Solid Steel Housing, Made in Italy”, 20 pounds, and 8 by 9.5 inches of counter — about 76 square inches, which is actually less than the 86 a Bambino occupies, because the E24 is deep-and-narrow where the Bambino is long. It is 1.8× the Bambino’s weight in that smaller area. The listing also files “Self Serviceable” among its special features, which is a real and unusual thing for a manufacturer to advertise.

1200 watts is the lowest figure of any machine on this site that publishes one. Wattage is not performance, but it does bound how quickly a cold machine can put heat into water, and nothing on this listing suggests a fast-heating design. Amazon shows a free 30-day refund or replacement window. The listing states no warranty length at all, which is worth holding onto for the next section.

4.4 stars across 3,169 reviews — and one bad pattern

Amazon groups 1,229 topic mentions across eight themes on this listing. Most of them say what you would expect of a well-liked manual machine. One of them is the most one-sided topic in the corpus, and it is not a compliment.

The leakage topic is the finding on this page, and it is not a small one. 94% of 62 mentions are negative. Nothing else in the corpus, in either direction, is that one-sided — not even appearance, which is the kind of topic that usually runs unanimous. Amazon’s own description of the cluster is water spitting from the machine and a steam wand that drips continuously.

Put that next to the durability split at 62% negative, with Amazon’s summary naming failures at around eighteen months, and next to a listing that states no warranty term, and you have a specific thing to do rather than a vague worry: buy it where returns are easy, and find out what warranty the seller offers before you pay, because the listing will not tell you and the failure pattern is not early enough for a 30-day window to catch.

We are not going to soften this by pointing out that performance runs 17% negative and espresso quality 12%. Both are true, both are good, and neither is an answer to a machine that a great many owners report leaking. The fair summary is that people who own a working one are happy with the coffee, and a meaningful minority do not have a working one.

Two tools, because this machine has none

These are here because the E24 automates nothing, which is unusual enough on this site to be worth tooling for. There is no display, no shot timer, no PID, no programmed volume and no gauge on the front. The listing calls the operation mode semi-automatic and lists its entire interface as “buttons”. Every judgement the machine could have made for you is now yours, and the first one you will get wrong is the grind.
