When the Perfection 660 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 Perfection 660 is a WMF bean-to-cup with a 3.5 inch touchscreen, 16 preset coffee and milk drinks and 3 tea drinks, among them, by WMF’s account, a cold nitro coffee. Six user profiles hold up to 48 of your own drinks between them.

The milk runs through a tube from a 0.6 litre glass container that WMF supplies. The water tank holds 3 litres, and at 25 centimetres wide it is narrower than the 860L. The front is Cromargan, the rest of the housing matt black plastic.

Who for: A household making many different drinks that wants a narrow machine with a large water tank.

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.

Accessories that fit this machine

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.

Maintenance

Recommended

Cleaning tablets

For flushing the brew group. Coffee oils settle where you cannot reach, and a bean-to-cup with a cleaning programme expects a tablet to go with it.

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.
