When it comes to semi-automatic espresso machines, Rocket’s are the cream of the crop. Not only are they beautifully designed with their shiny stainless steel housing, but they also have state of the art mechanics as well, making them excellent for espresso production.
If you’re lucky enough to have purchased a Rocket Espresso machine, you likely rushed home so you could proudly display it on our your counter in all its glory. So, now you’ve got the machine all set up, plugged in, filled with tasty filtered or reverse osmosis (RO) water and you are good to go. But wait – what’s that flashing green light on the front of the machine? You’ve just filled the water tank, so why is the machine telling you that it is empty?
Never fear, your machine is not broken! This is a common question our customer service team receives about all Rocket machines, and luckily it is easy to fix. The problem is your Rocket is too smart for its own good and thinks the water reservoir is empty when the machine’s sensor doesn’t detect any minerals in the tank. In this video, Teri walks us through what causes this error and explains an easy solution.

One of the most popular New Year’s resolutions is to clean up and de-clutter around the home, so why not start by performing some maintenance on your espresso machine? One of the easiest steps is to descale, which, depending on the mineral content of your water, should be done every one to three months. If you don’t descale your machine, mineral deposits can build up inside the machine and cause the water tubes to clog and/or reduce the brew temperature.
Since we’ve discussed how to descale a couple of different types of espresso machines in the past, we thought we’d focus on a perennial favorite – the Saeco Aroma, which has a stainless steel boiler. Not only does this durable little machine have a great reputation, but descaling it is also easy and painless. Just mix a descaling solution like Dezcal with 32 oz. of warm water, pour it into the machine’s water reservoir, pull the solution into the boiler by running water through the steam wand, and let the solution soak for a while. Then pull more solution into the boiler and let it soak in again, rinse and you are ready to go! However, it’s important to make sure to taste the water in your machine before you start brewing again to ensure there is no descaler left over in the machine, which will cause your espresso to taste a little funky.
The lesson of this story is – care of for your Aroma, and it will reward you with great tasting espresso for years to come. For complete step-by-step instructions on how to descale your little dude, watch Bunny take us through this simple process.
We’ve descaled double boilers, heat exchangers, every superautomatic under the sun and even simple thermoblock-driven machines, but in all of our years giving scale the what-for inside espresso machines, we had not descaled a La Pavoni. So when Sam’s Uncle Bob asked us to show him the ropes, we couldn’t pass up the opportunity to delve into something completely new!
The first part of the process, of course, was to find a willing participant, and Bunny stepped in to do the job. After working in our retail store for years and performing tune-ups for customers, she knows a thing or two about descaling machines, so we tasked her with researching how to perform it on a manual lever style machine like the La Pavoni. What she learned (and what we then filmed) was deceptively simple! It will take some time, patience, a little elbow grease and, of course, some Dezcal, but it was a very effective method for removing scale within the La Pavoni’s boiler and on its heating element.
Watch as she guides us through the process. And if you happen to have a La Pavoni or a lever machine that you descale in a different way, we’d love to learn new techniques! Post your process in the comments and we’ll share with the class.

Perhaps more than any other home espresso machine, the Rancilio Silvia has a devoted, storied following. Originally designed by commercial espresso machine manufacturer Rancilio to give as a gift to their distributors, it quickly took on a life of its own and, for many years, was considered the go-to espresso machine for home enthusiasts who wanted to craft specialty coffee quality drinks.
Owing to its creators, the Silvia featured largely commercial-grade components, which hadn’t really been on offer for many home-class espresso machines before. With copper-plated brass internals, a 58mm standard chrome-plated brass portafilter and a traditional steam wand, it provides the tools you need to make excellent espresso-based drinks. But it does have one major design element that have caused some folks to deem it as ‘finicky.’
The Silvia is a single boiler espresso machine that employs a rather simplistic temperature regulation system — a bi-metal thermostat that engages and disengages the heating element by bending one way or the other (as determined by the machine’s temperature). So, if the machine is on the lower end of the temperature spectrum, a small metal piece will bend one way in order to make a connection and allow the electrical current to reach the element, beginning the heat up process. On the other side of the spectrum, once the machine’s internal temperature reaches a high that causes this thin metal to bend in the opposite direction, it will interrupt the current and the machine will cease heating up. This is a very common method of temperature regulation used in appliances or thermostats around the home, and while it is cheap, reliable and effective, it also lends itself to a wide arc of variable temperature.
When these temperature variables happen in your home, you put on a sweater; when they happen in your espresso machine, they can result in marked differences in shot quality. At the hottest end of the spectrum, your coffee will taste burnt and over extracted, while on the coldest end it will taste sour. One way you can ensure you’re brewing at the right temperature, however, is to ‘temperature surf’ — pull just enough cold water into the boiler to engage the heating element, then, after it’s heated up to its highest temp, wait a bit (to allow the temp to come down from its hottest level) and then brew. Another way you can manage this is to circumvent the bi-metal thermostat altogether and install a PID!
The PID will take over managing the boiler’s temperature by using a more sophisticated and programmable electronic chipset. At SCG, you have the option of ordering a Rancilio Silvia from us that already has an Auber PID installed, which offers the ability to program the boiler temperature and elements of extraction such as pre-infusion and shot timing. In the video below, Gail shows us how to get into the Auber PID unit that we install on the Rancilio Silvia, navigate through it and program it for your specific needs.
Yes, this was a rather extensive and detailed lead-up to a simple how-to video, but knowing is half the battle, friend. And the other half is brought to you by espresso.

While the Saeco Minuto offers some unique functionality compared to Saeco’s other superautomatic espresso machines — such as brewing coffee at a lower pressure to produce a more drip coffee like flavor — it still offers a Test Mode to help diagnose and resolve issues with the machine.
Knowing how to get into Test Mode is important, as it can assist you in determining what a particular error might be and how you can fix it. Since you can run each functional component separately, you can test things like whether or not the pump is working or if the grinder is grinding but not dosing. You can also learn helpful info like how quickly your grinder is rotating, how many drinks you’ve made and more.
In this video, Brendan guides us through Test Mode on the Saeco Minuto — how to get into it, navigate through it and interpret what its telling you. Once again, indispensable knowledge for Minuto owners everywhere!
When you have an excellent tech resource like Brendan around, you sometimes have to just lock him in a room with a bunch of superautomatics and force him to teach you his ways of diagnostics and troubleshooting! Okay, we really didn’t have to lock him in the room — he was more than willing to share his expertise with us — but we did spend an afternoon with him as he explained the Saeco Talea Giro’s test mode and errors for us.
As you may have learned from our other forays into Test Mode, this is a wonderfully helpful tool that you can use to run each functional element of your superautomatic separately, without making coffee, in order to determine what might be the cause of an issue with the machine. Is your machine not brewing because the pump isn’t working, or are you simply grinding your coffee too finely? You can find out by running the pump to see if water comes out of the machine, sans coffee.
After he guides us through Test Mode, Brendan then dives into the Talea Giro’s more cryptic errors and alarms — since it doesn’t have a display screen and only a series of symbols and lights to communicate any issues it might be having, it can sometimes be difficult to interpret. He gives us a few tips and tricks in understanding what the errors mean and how you might be able to easily resolve them.
Designed for high capacity commercial environments, the Rancilio KRYO is an espresso-grade grinder that enables you to craft shot after sumptuous shot. With its 64mm stainless steel burrs, dosing chamber and unique aluminum fins (that dissipate the grind temperature) it quickly grinds up coffee for your double shots. But one key element of consistent shot flavor is to ensure that you’re using fresh coffee, and not inadvertently melding flavors with a built-up melange of old coffee grounds.
To avoid that, we highly recommend that you clean the grinder on a regular basis — at least monthly, if not weekly. Getting into it, taking it apart and then getting it back together again can seem a bit overwhelming, however, so we’ve filmed a how-to video for you! Hopefully, watching it will give you the confidence you need to take this project on.
Watch as Brandon walks us through the whole process, gives us tips on best practice and even tutors us in the ways of knowing when it’s time to replace the burrs. Even if you don’t want to dive into the full cleaning every week, doing it each month will improve your coffee flavor, and your customers will definitely dig it!

While it’s true that the Saeco Syntia offers a display with icons and text that will signal to you when something is going wrong, we often hear from folks that aren’t clear on what’s going on with it. Is that a close up of a fly’s head or a symbol telling you to descale? Is it signaling that the tap is open a smidge or is it warning you that snakes are coming out of your espresso machine? These are the big questions, folks.
In our next series of Saeco superautomatic espresso machine troubleshooting, Brendan takes on the Syntia series. Using the SS model, he first guides us through Test Mode, which is the highly useful diagnostic tool that enables you to run each functional component separately, and without making coffee, so that you can deduce what might be going on with your Syntia. Then, we dive into interpreting the rather cryptic symbols that appear as errors or alerts on the machine.
Even though we used the SS model for this demonstration, much of this applies to the Syntia Focus and Syntia Cappuccino models, too. If you’ve wanted to learn more about the inner workings of your machine, these are your go-to videos!
Since the Saeco Intelia Focus features a pretty darn clear menu screen that will alert you specifically to any issues and errors, we thought that going over them was of very little import. Instead, we wanted to focus on its Test Mode, which is cool because it allows you to run each of the functional components separately and independently of actually making coffee. So if your machine is behaving badly (naughty machine!) and you want to find out what might be the source of its bad behavior, test mode can be a helpful deduction tool.
Watch as Brendan guides us through test mode — how to get into it, navigate through it and then use it to diagnose any functionality or performance issues with your machine. And while we did use the Saeco Intelia Focus as the demo machine for this troubleshooting video, this process applies its Cappuccino and SS counterparts, too.
If you’re running a fast-paced coffee business, slinging a high volume of milk-infused espresso drinks throughout the day, you’ll be giving your commercial espresso machine’s steam wands a serious workout. This results in some degradation of a few of its internal parts, which will require replacement in order to maintain full steam functionality.
But performing this regular maintenance doesn’t have to mean a tech call if you know your way around your machine’s steam arm assembly. In fact, since performing this maintenance can be required sometimes as often as every 6 months, learning how to do it yourself will save you money, in addition to extending the life and performance of your machine. Sure, it sounds a bit daunting, but we’re here to help!
The first demonstration we have for you is on the Rancilio series of commercial espresso machines that feature their C-Lever functionality. We asked our commercial expert, Brandon, to guide us through how to remove, disassemble, replace parts, reassemble and then reinstall the steam arm on the Rancilio Classe 9, but this process applies to the majority of their machines. If you’re starting to notice water or steam leaking from the wand when it’s in its ‘off’ position, this is a hallmark sign that it’s time to perform this maintenance. So watch this video and then dive in!
