EssentialDescaler
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.

When the EQ.300 extraKlasse 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.
The EQ.300 is the Siemens entry range: espresso, café crème, cappuccino and latte macchiato at one button, with ceramic burrs and a removable brew group.
What it lacks against pricier Siemens models is mainly choice: four drinks at one button, and a 1.4 litre water tank.
Who for: Anyone who wants a simple Siemens with cappuccino at a button.
Strong on paper
- Cappuccino at one button
- Ceramic burrs
- Removable brew group
Weaker on paper
- Small water tank
- Four drinks at one button, fewer than pricier Siemens models

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.
The maker states no maintenance intervals for this machine that we have been able to read.
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: €117.80 with the cheapest kilo in our catalog, €445.45 with the dearest.

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

Go to CoolblueBeans 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.
