Gaggia Classic Pro E24 (RI9380/46) Espresso Machine

Classic Pro E24 or Classic Evo Pro: one code, two boilers

Gaggia North America sells this machine as the Classic Pro E24 and calls it the newest version, with a lead-free brass boiler. Its E24 manual is headed Classic E24, RI9380 (SIN035R), and Gaggia's exploded-view file lists RI9380/46-E24 as the stainless-steel, 120V US model, which is the code on the Amazon listing.

The names are not uniform. This listing's title says E24, but its item table and product description call it the Classic Evo Pro. Gaggia's 2023 service manual for the Classic 2019 and Classic Evo Pro lists the same RI9380/46 code and 12NC number with an aluminium boiler. Gaggia's exploded view for the Classic Evo/E24 also lists an aluminium boiler assembly for 120 to 240V and a brass one marked 'only Jap', while Gaggia North America's product page describes the E24 with a lead-free brass boiler.

Both parts documents are dated 2023, while the product page was read in September 2026. The code alone does not separate the two and Gaggia's own documents disagree on the boiler, so treat the brass-boiler details in this guide as Gaggia's page claim and confirm the machine with the seller or on arrival.

The boiler claim, the 58mm portafilter and one small boiler

Gaggia's page lists a single-boiler, dual-use design with a lead-free brass boiler of 3.5 ounces (the parts list and service manual show aluminium, see above), a 1,370W boiler and 1,425W total at 110 to 120V. It describes a solid brass boiler and group head, a 58mm stainless-steel portafilter, a 17-gauge stainless body, mechanical rocker switches and a 72-ounce water reservoir.

The pump is listed as a 15-bar Ulka with the overpressure valve calibrated to 9 bar, and Gaggia's page says filter baskets hold 7 to 18 grams. The maker's accessory list is a plastic tamper and a ground coffee scoop. It also lists a bottomless portafilter and a chrome double-spout portafilter as Gaggia add-ons.

The crema perfetta filter and the traditional filters

The manual lists three filters as supplied. The crema perfetta filter for one or two cups comes fitted and is to be used only with the frothing jet device. The traditional one-cup and two-cup filters are, in the manual's words, like those in professional bar machines, need manual skills and must not be used with the frothing jet device.

The manual warns that using the crema perfetta filter without the frothing jet device will squirt out the coffee and may cause burns. It advises starting with the crema perfetta filter, then moving to the traditional ones with experience, and says to add one measuring scoop of finely ground coffee per cup. There is no grinder in the box.

Brewing and the wait between coffee and steam

Before the first coffee the manual has you load the circuit, run the whole tank through the steam wand and group, and preheat the filter holder in the group. It says to wait for the coffee temperature light before brewing and to keep the rinsed filter holder installed, without over-tightening, between shots so the group stays at temperature.

This is one boiler for coffee and steam. To make another coffee right after steaming, the manual says to lower the boiler temperature by running hot water through the group, otherwise the coffee may taste burnt and you may get burnt. Steaming should last no longer than 60 seconds, since longer can empty the boiler and means loading the circuit again.

Steam wand, hot water and pods

For milk the manual says to press the steam button, wait 15 to 20 seconds for the steam light, purge condensation and keep the nozzle just under the milk surface near the jug edge. It warns the wand can be very hot and should be moved only by its rubber tip. After frothing, clean the wand with a damp cloth and clear the nozzle hole with one or two seconds of steam.

Hot water comes from the wand: open the steam knob and press the brew and steam buttons together. Gaggia's specification list also shows coffee pods, but the manual describes only ground coffee and its filters, and its safety pages warn against putting anything but ground coffee in the pressurized filter holder. The Amazon product description, written for the Evo Pro, instead lists commercial single and double baskets and a pressurized basket for ground coffee or ESE pods, so confirm the basket set and pod support with Gaggia before planning around it.

Cleaning, descaling and where the sources disagree

The manual says to descale with Gaggia's product only and never with vinegar, and its descaling section says every 2 months. Its cautions say descaling every 2 to 3 months even with purified or bottled water. It warns that accessories or parts Gaggia does not recommend void the warranty, which matters if you plan an aftermarket portafilter.

The sources also differ on size and weight. Gaggia's page gives 8 inches wide, 9.5 deep, 14.2 high and 19 pounds, while the Amazon item table gives 8 deep, 9.5 wide, 14.2 high and 20 pounds. Gaggia's page calls the machine Classic Pro E24 and the manual calls it Classic E24; the manual does not print the RI9380/46 suffix.
