Neretva PE3670U: problems, parts and running costs

Checked: 2026-10-06

Summary

The Neretva PE3670U is a compact 1350 W beginner espresso machine that can make satisfying espresso and milk drinks with a good grinder, but its fixed timed shot cycles and pressurized basket limit how far you can dial it in. Running costs are coffee, descaling supplies and occasional replacement parts. It makes the most sense as a roughly $100-class purchase for a beginner with limited counter space.

Common problems and fixes

Watery or sour shots — a 2026 owner struggled with this and found the stock program runs a strict timed cycle rather than allowing easy manual yield control; the fix is grind, dose and yield discipline, which matters more than the simple controls suggest. [4]
Stock basket too small for 18 g — the pressurized basket could not comfortably take an 18 g dose, making it hard to dial in specialty-style ratios. [4]
Limited clearance under the steam wand — noted in a 2025 hands-on review; tall milk pitchers may not fit. [7]
Cooldown needed between steaming and brewing — the machine requires a cooldown between steaming milk and the next brew. [7]
Pressurized basket limits dialing — the 51 mm pressurized setup is hard to compare with 58 mm prosumer machines and complicates bottomless or non-pressurized dialing. [1][4]

Parts and consumables

51 mm portafilter for PE3670U — $20.99 from Neretva’s US accessories page; replacement interval not reported. [6]
PE3670 steam wand — $7.99 from Neretva’s US accessories page; replacement interval not reported. [6]

Yearly running cost

Not enough data. The sources mention coffee, descaling supplies and occasional replacement steam or portafilter parts as ownership costs, but no yearly total is given.

When it is a good buy

A 2026 owner describes the machine as roughly a $100-class purchase, and exact-model third-party reviews place it around €110. It makes the most sense for a beginner with limited counter space who will pair it with a competent burr grinder and accept pressurized-basket workflow. Buyers who want precise manual shot control, 58 mm accessories or easy non-pressurized dialing should look at a more configurable machine. The sources do not name specific alternative models.
