Price alert

When the EQ.900 iAroma TQ923 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 TQ923E09 is the EQ.900 iAroma with one 375 gram bean hopper instead of two. Otherwise the same base as the pricier TQ927E03: a 6.8 inch touchscreen, a baristaMode in which you set the brew parameters yourself, Home Connect and a 0.7 litre milk reservoir in the machine.

What it lacks against the TQ927E03 is the second grinder and the active cup warmer. Anyone who always uses the same beans does not pay for those with this version.

Who for: Anyone who wants the large screen and the settings of the EQ.900, with one kind of bean.

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: €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.

Recommended

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.
