De'Longhi EC155 Review (2026)

The EC155 is one of the oldest espresso machines still turning up in search results, and that's the first thing worth explaining rather than glossing over. It's been around for more than 15 years, long enough that De'Longhi's own US site currently lists it as out of stock with a "notify me" option, not discontinued, just not reliably stocked direct from the brand. You'll still find it on Amazon and through other retailers. Whether that's worth your money depends less on nostalgia and more on a few real mechanical shortcuts baked into a 15-year-old design.

The verdict up front

The EC155 is a genuine pump espresso machine with a stainless steel boiler at a price De'Longhi's current budget lineup usually reserves for thermoblock units. That's a real point in its favor. Set against it: no 3-way solenoid valve, which means the portafilter keeps dripping watery coffee after each shot, and independent testing found shot quality drifting when you pull several in a row. If you're shopping new in 2026, De'Longhi's own current entry-level machine, the Stilosa, addresses some of this and is easier to actually buy direct. The EC155 mostly makes sense if you already own one, found one secondhand at a fair price, or specifically want the stainless steel boiler over the Stilosa's thermoblock.

What's actually inside

The boiler is stainless steel with dual thermostats, one for espresso, one for steaming, which is what De'Longhi's own product page calls out as the EC155's defining spec. A lot of machines at this price point have since moved to thermoblock heating and skip the stainless boiler entirely, including De'Longhi's own current Stilosa.

The 3-in-1 filter holder is the other piece De'Longhi highlights directly: it ships with double-wall (pressurized) baskets for single and double shots, and also accepts E.S.E. pods if you'd rather skip ground coffee and tamping entirely. Independent sources describe the portafilter as roughly 51mm, though that figure comes from third-party measurement rather than De'Longhi's own spec sheet, so treat it as the best available estimate rather than an official number. The pump runs at 15 bar, per the listing name itself, regulated down at the puck the way every espresso machine's pump pressure is.

The steam wand is a panarello-style swivel design. There's no built-in grinder, so you're working with pre-ground coffee or pods unless you add a separate burr grinder.

The mechanical shortcut that actually matters

Here's the real limitation, and it's not about taste so much as design. The EC155 has no 3-way solenoid valve, the part that releases residual pressure from the group head the instant a shot ends. Without it, the portafilter keeps dripping thin, watery coffee into your cup for a few seconds after you'd expect the shot to be done. It's a cost-cutting omission common at this price tier, not a defect specific to this unit, but a clean-cutoff recipe assumes a 3-way valve this machine doesn't have.

Reviewers who've pulled multiple shots back to back report a related pattern: the first shot or two come out fine, but a third or fourth in quick succession starts tasting thinner and more sour, consistent with the single stainless boiler losing ground on temperature and pressure recovery under repeated use. For a single morning shot or two, that's unlikely to matter. For entertaining or back-to-back drinks, it's a real ceiling.

Water tank capacity is listed differently depending on the source, somewhere in the 34 to 35 ounce range, so I'm giving the range rather than picking a single figure. The machine is self-priming, so there's no manual priming step before first use, and a cup-warming plate sits on top for preheating cups while you pull a shot.

Buying one in 2026

This is the part that actually changed since the EC155 first launched. De'Longhi's own US product page for the EC155 currently shows it out of stock, with a "notify me" signup rather than an add-to-cart button. That's not the same as a discontinuation notice, the page is still live and the model number hasn't been pulled, but it does mean De'Longhi itself isn't your reliable source for a new one right now. Amazon and other retailers continue to list it, and prices for a 15-year-old model with inconsistent direct-from-brand stock can run higher than you'd expect for what it is.

If you're buying new today rather than replacing one you already own, it's worth comparing directly against the Stilosa, De'Longhi's current entry-level machine. The Stilosa trades the EC155's stainless boiler for a thermoblock, and I haven't found independent confirmation that it solves the 3-way valve omission either, but it's the model De'Longhi is actually stocking and supporting right now, which counts for something when something eventually needs a part or a warranty claim.

Who should buy the De'Longhi EC155?

Buy it if you already own one and are deciding whether to keep using it, you found one secondhand or on clearance at a fair price, or the stainless steel boiler specifically matters to you over a thermoblock alternative.

Skip it if you're buying new without a specific reason to want this exact model, you want a 3-way valve for clean shot cutoffs, or you'd rather buy from a listing De'Longhi itself is actively stocking. The Stilosa is the more straightforward buy for most people starting from zero in 2026.
