Maintenance
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 Lumero 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 Lumero is WMF's portafilter machine: a matt stainless steel housing, a thermoblock that by WMF's account is up to temperature within a minute, and two buttons, for one or two cups. You set the temperature, the volume per cup and the water hardness yourself.
There is no grinder, so you use ground coffee or a separate grinder; WMF sells a Lumero grinder in the same design. You froth milk yourself with the steam wand, and a tamper comes in the box.
Who for: Anyone looking for a simple portafilter machine that looks good on the counter.

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.
- Descaler
- Not stated
- The machine says when. WMF gives no interval.
We cannot price anything for this machine: what the maker requires is not in our catalog, or the maker gives no interval.
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.

Accessories that fit this machine
Picked on what this machine does and does not do itself
Milk
EssentialMilk jug
A stainless jug of around 600 ml is the difference between milk that froths and milk that boils. The shape of the spout decides whether you can pour anything with it.
€12.95

Grinding
EssentialCoffee grinder
Without a grinder in the machine this is not an accessory but a second purchase. Budget something close to the machine itself. On pre-ground coffee no portafilter machine gives you what it can do.

Brewing
RecommendedKnock box
The puck has to go somewhere, and the bin clogs with wet coffee within a week. A box with a rubber bar is quieter than it sounds.

Brewing
Can waitCoffee scale
Dosing by eye is why the same machine tastes better on one day than the next. A scale accurate to a tenth of a gram, with a timer, turns pulling espresso into something repeatable.

Go to bolBeans 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.
Segafredo
Segafredo Intermezzo
