Price alert

When the EQ.500 iAroma drops

Espresso machines drop hardest around Black Friday and in the weeks before Christmas. Leave your email address and pick below what you want to hear about.

With the EQ.500 Siemens sits between the mass-market brands and Jura: better finished than a Philips, but not in the price class of a Swiss machine.

The selling point is autoMilk Clean, which flushes the milk system after every drink. That is not a luxury but maintenance: a milk system that never gets rinsed is the most common reason a bean-to-cup dies early.

Who for: Anyone who wants to keep a bean-to-cup a long time and not have to remember the upkeep.

Compared with similar machines

Against 49 other bean-to-cups between €355.00 and €749.00, on the specifications the maker publishes.

Width: 27.2 cm, wider than most (usually 24.6 cm)
Weight: 8 kg, lighter than most (usually 8.4 kg)

Same machine, different model number

These versions are the same appliance under another model number, often only a different colour. The prices differ considerably, so it pays to look at all of them.

This is what we know for certain. Dimensions and capacities the manufacturer or the shop does not state are left out rather than estimated. A measurement or a tank volume that is not there is one we do not have.

What does it cost a year to maintain?

A worked example, not a specification: 2 cups a day (730 a year), the intervals from the maker's manual, with the water filter the maker recommends, and the lowest price in our catalog today.

Water filter · 6 a year: €49.98; Siemens: replace the water filter after 2 months at the latest. 2 x BRITA Intenza water filter, 3 a pack, at €24.99
Descaler: Not stated; The machine says when, later with a filter. Siemens gives no interval.
Cleaning tablets: Not stated; The machine says when. Siemens gives no interval.

Maintenance a year (the priced lines above)

€49.98

How often you descale depends on your water hardness. Where the maker gives no interval for it, we leave it out rather than estimate it.

Beans, counted separately

6.57 kilos a year at 9 grams a cup: €108.34 with the cheapest kilo in our catalog, €445.45 with the dearest.

Maintenance

Essential

Descaler

Limescale is what most machines die of, and vinegar attacks the seals. A liquid descaler declared suitable for espresso machines does the same job as the maker’s own branded fluid, usually for less.

BRITA Intenza water filter

The filter Siemens and Bosch share. It stretches the descaling interval and takes the off-notes out of hard tap water.

Beans for this machine

Every bean fits every machine. What differs is the order: on a bean-to-cup the 100% arabica beans come first, because dark-roasted blends carrying robusta give off more oil and that clogs a built-in grinder sooner.
