The Nuova Simonelli Aurelia Wave Semi-Automatic espresso machine gives an experienced barista direct control over the beginning and end of every extraction. It is the streamlined Aurelia Wave for cafés that want proven high-volume steam and brew performance without programmed shot volumes or a digital display. Choose the 2 Group model for a focused bar and the 3 Group model when more simultaneous production is essential.
Why choose the Aurelia Wave Semi-Automatic?
This version is built around hands-on workflow. Each shot is stopped by the barista, making it a strong fit for specialty programs that value visual judgment, scale-based recipes and manual intervention. Nuova Simonelli's Soft Infusion System (SIS) helps manage minor tamping inconsistencies while the reverse mirror lets the operator monitor the extraction without bending below the group.
- Manual shot control: the barista starts and stops each brew cycle.
- SIS soft infusion: supports more forgiving, repeatable extractions across a busy team.
- Raised group heads: accommodate taller takeaway cups while remaining suitable for traditional cups.
- Cool-touch steam wands: reduce heat transfer to the exterior of the wand during milk service.
- Automatic cleaning program: simplifies end-of-day group maintenance.
- High-volume boiler platform: a 14 L boiler in the 2 Group and 17 L in the 3 Group.

Factory choices and accessories
Black is the standard finish. Nuova Simonelli also lists red or pearl-white side panels and base as factory color choices. Pod kits, water-treatment equipment and extended installation/service plans can be quoted separately. These are project options rather than separate machine versions, so the product selector remains focused on the two correct sellable configurations: 2 Group and 3 Group.
What is included
The official user manual lists the machine, a tamper, one single basket, one double basket per group, one blind basket per group, basket springs, portafilters totaling the number of groups plus one, double spouts, one single spout, a 3/8-inch inlet hose and a 3/4-inch drain hose. Final contents can vary by production revision.

Frequently asked questions
Does the Semi-Automatic stop shots automatically?
No. The barista controls both the start and stop of extraction. If programmed dosing is a priority, the Volumetric or Digit version is the better match.
Is this machine plumbed in?
Yes. Both group sizes require a dedicated water supply, proper filtration and an open gravity drain. Review the installation PDFs before scheduling delivery.
Can I order a different color?
Yes. Black is standard, with red and pearl-white panel/base choices listed by the manufacturer. Contact us to confirm lead time and final configuration.
Is professional installation recommended?
Yes. Commercial 220 V power, plumbing, drainage, water treatment and local code compliance should be prepared and verified by qualified trades before installation.
