De'Longhi Linea Classic

Moderate ecosystemBeginner ★★★★★Machine Under $300Budget 51mm beginner machine - forgiving, pressurized, quietly upgradeable.

Tamper:: 50mm or 51mm
Portafilter:: pressurized
Stock:: Ships with pressurized (dual-wall) stainless single- and double-shot baskets that meter flow through a small hole, so they forgive an uneven grind and reliably build crema. That forgiveness is also the ceiling: the dual wall masks real puck resistance, so most of the shot quality comes from the basket rather than your technique.
First upgrades:: Tamper -> Filter basket -> Milk jug
Avoid:: Confirm any portafilter, basket, or bottomless portafilter is listed for the EM450M three-ear 51mm portafilter - De'Longhi's 51mm ear/tab geometry differs from other brands' 51mm parts. This is a single-thermoblock pump machine, and machines in this price class typically aren't designed to backflush (no 3-way solenoid), so blank/blind baskets and backflush cleaning discs generally don't apply - confirm in the EM450M manual before buying a backflush disc. The bundled 'tamper' is a lightweight plastic scoop-tamper; treat a real 51mm flat tamper as an upgrade, not an accessory match to the stock piece.

Before you buy

Buy first

Tamper - Replaces the bundled plastic scoop-tamper with a real 51mm flat tamper, giving you a level, consistent puck - the single biggest cheap improvement on this machine.

Skip for now

Backflush cleaning discs and blind baskets - this machine isn't designed to backflush.
A single-wall basket until you also have a real grinder and tamper, or it will just pull sour, gushing shots.

Avoid

Any 54mm or 58mm accessory - the EM450M is 51mm and the wrong size won't seat.Generic '51mm' parts not listed for the De'Longhi three-ear portafilter, whose ear geometry differs from other 51mm machines.

Common wrong buys: Expecting espresso-bar results from the pressurized baskets - they build crema but cap the flavor ceiling; the single-wall upgrade plus a real grinder is what unlocks it. · Buying 54mm or 58mm accessories because they're everywhere online - this machine is 51mm, so the wrong size simply won't seat. · Skipping descaling - the thermoblock scales up quickly on hard water and loses temperature stability if neglected; check your manual for the descaling schedule. · Leaving the frother wand un-purged, so dried milk clogs the air intake and froth quality drops. · Grinding too fine for the pressurized basket, which chokes flow and floods the group even though the basket normally forgives grind.
