Espresso machines have specific requirements when it comes to water. There are two primary considerations: filtration and hardness.

Filtration gets rid of tiny particles, such as sand or rust, in your water. If these particles were allowed to enter your machine they could cause all manner of trouble, particularly by clogging the precise valves and mechanisms in your espresso machine. Almost any water filter will do the job, whether it’s the one built into your fridge, a Brita, or a whole house filter. Ensuring that this filter is replaced in proper time will be important to ensure machine health.

Water hardness is equally important. First, use the water hardness test strips included with your machine to test the water you plan to use with your machine. Ideally, we want a hardness of between 35-85 ppm (parts per million). Hardness refers to the dissolved solids in your water. Common dissolved solids are things like magnesium, calcium, and various forms of sodium. These dissolved solids are what make water, and therefore espresso, taste good. But too much will result in scale buildup in your machine. Scale can cause irreparable damage to your machine by clogging and forming a mineralized layer over the surface of metal parts. The process of descaling is even more damaging, eating away at the machines metal internals. Luckily, scale can be entirely avoided by keeping your water hardness within the recommended TDS range of 35-85 ppm.

There are numerous methods to soften your water should its dissolved solid content be too high.

A note on RO (Reverse Osmosis) or Distilled Water

Taste aside, espresso machines require some mineral content in order to function properly. Their steam boiler fill probes, in particular, use the conductivity of water to detect the water level. With no dissolved solids, they’ll overfill, giving you water instead of steam. You must add some mineral content back in. Our recommendation is Third Wave Water packets which are designed to offer ideal flavor and to be safe for your machine.

Reservoir Solutions

Our first recommendation is an in-reservoir water softening pouch. They’re affordable, last 4-6 months, and are very effective. Using RO water purchased by the gallon in combination with Third Wave Water packets is another great option.

Direct Plumb Solutions

For machines that are plumbed in, we recommend our Water Softening and Filtration kit. It includes everything you’ll need to ensure the water is safe for your machine and delivers the best taste for your espresso.

No matter what solution you pick we recommend testing the water coming from your machine’s group head every few months. City water hardness changes seasonally and softening systems wear out. Routine testing will ensure you keep your machine safe.

First time setup

First, there is a pair of connected cables that extend from the espresso machine - one with a black tip and one with a white plastic tip. These must be routed to the under-counter case and connected to their respective ports at the top right corner of the rear face. Ensure these are firmly seated to avoid disconnection in the future.

Next, you'll need to connect the braided line which extends from the under-counter case to the espresso machine. Thread the line up through the hole in your counter and attach it to the water inlet found on the underside of the espresso machine at the back. Hand tighten and then apply an additional half-turn with an adjustable wrench.

Reservoir setup

The machine arrives in reservoir mode, so you can simply fill the reservoir with your filtered and softened water, leaving a few inches at the top to prevent spillage. The reservoir is removable. Ensure that you do not spill water on top of the machine when filling, as this may cause electrical damage. Once the reservoir is full, turn on the main power switch found at the lower right corner of the face of the espresso machine.

If your reservoir is full, some lights are on, but the PID display is off it may be due to the machine not detecting the magnet. This may be due to the magnetic float coming out of its housing in which case you should find it floating loose in the reservoir. Simply place it back inside its plastic housing with the black circular magnet facing the front of the machine and press the plastic clip into place above it.

Water line setup

Find the braided line included in the box. Attach one end to the threaded water outlet which is found on top of the under-counter case, adjacent to its built-in braided line. Hand tighten and apply an additional half-turn with an adjustable wrench. The other end connects to your water supply outlet.

Turn the valve found on top of the under-counter case such that it points toward the water spout icon. Next, flip the switch at the back of the under-counter case toward the water spout icon. You can now turn on the main power switch found at the lower right corner of the face of the espresso machine.

Programming PID and Settings

If you’d like to change either boiler’s temperature, you can do so using the two buttons on the PID. First, press both buttons at the same time, which will then display “T1." T1 represents brew boiler temperature. By pressing the plus button, you can enter that setting. You’ll then see the current target temperature (200 by default). By using the two buttons you can increase or decrease the temperature. Waiting for a moment will send you back out the main menu, showing “T1." From here, pressing the minus button will move you to “T2”, which represents the steam boiler temperature. You can enter and change this as well. Pressing the minus button again will exit the menu.

When it comes to brew temperature, we recommend staying between 195 and 200°F, using lower temperatures for darker roasts, and higher temperatures for lighter ones. As always, experimentation is highly encouraged. Steam boiler temperature is set to its maximum by default, and it’s probably best to leave it there for maximum steaming performance. You can also turn off the steam boiler using this switch hidden behind the drip tray. This can be handy during summer months when you know you’ll only be making iced lattes.
