How To: Brew Group Maintenance

You may be sensing a theme here…keep it clean! The best way to keep your machine out of the repair shop and performing optimally is to regularly maintain all of its components.

Your machine’s brew group is arguably the most important part, so taking the time to keep it in tip top shape means it will give you delicious espresso shots for years to come.

We’ve compiled some how-to tips for each of the basic styles of home espresso machines. If you need more assistance, refer to your user manual or give us a call.

Tech Tip: Don’t Burn the Midnight Oil

We often see single boiler machines (such as some models from Rancilio Silvia, Ascaso Dream Up) that have suffered from one of the silent ills of home espresso machines: Heat element abuse.

Sure, this is a something no one wants to talk about — it’s ugly, it’s bloated and it’s burned out. This is not a sexy subject, but we can’t stand by any longer and watch as it’s so cavalierly swept under the rug! It’s time for us to take a stand…and let you know how you can keep your single boiler machine from becoming just another expensive statistic.

Our How to Brew & Steam – Rancilio Silvia article outlines the basic brewing process that you should follow for any single boiler machine: Namely, steam your milk first and then pull your shots. Following this process enables the machine to pump in and steam the appropriate amount of water necessary to first steam a 12 – 16 oz. quantity of milk and then brew an espresso shot. If you do the opposite and brew the shot before you steam the milk, it will empty out the boiler and, the next time you go to make your coffee, it will attempt to warm nonexistent water, fatiguing the element over time and eventually burning it out.

This burn out could be the end result of hundreds of tiny daily misuses or happen in one big event — like when you’re having a party and need to make many lattes at one time. For the latter, be sure to follow the brewing guidelines and serve your guests coffee in shifts. Make some jokes. Show them how charming you are. Do whatever you need to do — just don’t abuse your espresso machine.

Superautomatics: No Love for the Oily Bean

One of the most common issues we see in our repair shop is a Superautomatic machine (such as a Saeco, DeLonghi or Jura Capresso) with a non-functional grinder. Often, the ‘Out of Beans’ light will be on, regardless of how many beans are in the hopper, and the grinder will cease functioning properly.

The cause? Those super dark roasted, oily beans! Superautomatics require a very dry bean, as the oilier beans leave too much moisture in the hopper and the grinder, eventually building up and clogging the machine. We really recommend that you try a lighter, drier roast, but if you just can’t break your addiction to oily beans, here are a couple of tips to keep your machine from breaking down over time:

  1. Each time you refill your hopper, thoroughly wipe out the entire accessible area with a highly absorbent paper towel
  2. Super fine grinds + oily beans = coffee cement, so dial your grinder in to the coarsest possible setting and you’ll mitigate some of the issue
  3. Regular maintenance & cleaning of your superautomatic will reduce the build-up from oily beans
