If you haven’t noticed, we love science! Of course the best part is conducting fun experiments and playing around with toys like the Fluke temperature probe. This time around, we were interested in seeing how some of our drip coffee makers compare when it comes to how consistent and how hot they actually get while brewing.
In order to complete this experiment, we lined up the Breville YouBrew, Capresso CoffeeTEAM TS, Bonavita Coffee Maker, DeLonghi kMix and Technivorm Moccamaster Coffee Brewer and tested each machine one by one. For the sake of consistency, we stuck the temperature probe at the bottom of each machine’s filter holder, and prepared a single brew with just water, no coffee. We might have gotten a more accurate reading by placing the probe right where the water comes out of the coffee maker, but it was not possible to do so on all of the drip coffee makers, so we didn’t structure our test that way. However, our quasi-scientific research will still give you a good idea of how the machines differ and how hot they heat the water. To find out which is the hottest, watch as Gail puts these five drip brewers through their paces.

Any café owner will tell you that the secret to success is having a good espresso machine as part of your setup, as it will supply you and your customers with delicious espresso for years to come. As such, you’ve done your due diligence, researched a variety of machines and ultimately decided that a commercial Rancilio espresso machine is the best option for you. However, if deciding on which machine to choose wasn’t tough enough, now you have to get your machine installed in your shop.
This may sound like a challenging and complicated process, especially once you open up the box and see your beautiful new machine accompanied by a bunch of wires and hoses. While it might look scary, installing a Rancilio yourself isn’t quite as hard as you think. The process can be broken down into six easy steps. And yes, when it comes to installing the electrical plug on a machine, we know that each hot wire is 110 volts (not 120) in order for the two to be equal 220 volts total. Since the machine wasn’t setup yet when we filmed this video, we hadn’t had the amount of espresso necessary for number crunching!
Of course when you have an expert in commercial machines, like Brandon, around it is hard not to put their skills to the test for the sake of knowledge. We had him plumb and wire-in a commercial Rancilio in our test kitchen to see the process in action. To simplify your installation process, follow along with him in this comprehensive video. If you have any questions, we’re always happy to help! Just let us know.
One of the hidden secrets of many espresso machines is that they come with an accessible test mode section. What is great about test mode is that it is an excellent resource for troubleshooting your machine. For instance, test mode can allow you to determine if components like your water pump, grinder or brew unit motor aren’t working because they are broken or because something in the machine has been misplaced and is keeping them from working.
One espresso maker that has this functionality is the Saeco Intuita. Luckily, as its name suggests, getting into the test mode section on this machine is more intuitive than it is on other espresso machines and only requires a few simple steps. Once you are in test mode, there are five different levels to explore, which allow you to test everything from the lights on the machine to the grinder. You can even test the machine’s sensors to make sure they are working properly, which is a great way to help pinpoint what is causing an alarm in regular mode.
In this video, Brendan shows us how to access test mode on the Intuita, guides through each of the different levels and explains how to use each one to diagnose any problems you are having with your machine.
It’s hard not to love the Crossland CC1. This compact machine is easy to use, makes consistently good shots and has a large water reservoir. However, just like every other espresso machine, the Crossland CC1 needs a little TLC every once in a while to keep it in good running order. One of the best places to start is with descaling, which will help keep mineral deposits from clogging up your machine.
What makes descaling the CC1 a little different than other machines is that it is really simple! The machine has a thermoblock that runs the steam wand, and on the brew side it has a boiler. This setup allows us to have water (instead of steam) come out of the steam wand, so the descaling solution will go through the boiler, through the thermoblock and out through the steam wand, ensuring that all parts of the machine get cleaned out.
To clean the Crossland CC1, we used our favorite descaler, Dezcal, which is a citric acid based product, mixed with 32 oz. of warm water. This mix is non-toxic, so while any leftovers in your machine might make your espresso taste funny, it won’t harm you. However, don’t be alarmed if you are using this solution to descale your espresso machine and the water comes out greenish-blue. It is normal for the water to come out this color if you have a lot of minerals built up in your machine, which the Dezcal is helping remove. If the water comes out fairly clear, it means your water is mostly mineral free. For more details on how to descale your CC1 and pick up a few extra tips, follow along as Gail completes the process in just one hour.
The fact that the Saeco Talea Touch does nearly everything for you (except fold your laundry) makes it one of our more popular espresso machines. Not only does this machine’s technology allow for easy brewing, but it also enables you to access the Test Mode section, so you can give it a “check up” and explore the cause of any issues that may be occurring.
One of the greatest benefits of Test Mode is that it allows you to freely operate the functionality of your machine. For instance, you can do things like check to see if your grinder is working without brewing a shot of coffee, monitor if your brew unit motor is running right or even see if your pump is in good shape. While this mode is useful, the Test Mode for the Talea Touch is one of the more challenging to get into. You must know a special code, as well as how use it, which are both cryptic enough to warrant the use of a secret decoder to finger them out. This is also the case for both the new and the refurbished Saeco Talea Touch Plus, which requires you go through the same process to access the Test Mode.
Luckily, we have something even better – our parts and tech expert, Brendan, who told us the secret code and how and when to enter it. Once we were in, he also showed us how to navigate through the system and play with the options, which are much easier to use.
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!
