What's the most important thing I can do to make sure my La Marzocco espresso machine keeps running normally? +

The most important thing you can do for your espresso machine is to use the right water. Most of the problems people experience with their machines stems from the fact they are using water that is outside of the specification given by La Marzocco for proper operation. Each of our machines ship with a water test kit so that you can make sure the water you are using is within spec. View our Water Specifications and enter the results of your test in our Water Calculator. Also, be sure to read through this Water for Home Espresso post we put together.

What is your return/ exchange policy? +

Parts & accessories returns or exchanges must be initiated within 30 days of receiving your order Items must be unused and in original packaging in order to receive a full refund. You can initiate a return for all parts & accessories orders at our Return Portal.  Once received and processed, refunds can take up to a week for your bank to generate in your account.

Espresso machines and grinders require further coordination to faciliate and must be initiated within 30 days of receiving your order. Equipment must be in new and unused conditioned otherwise we reserve the right to retain a 15% restocking fee.  In the event you would like to initiate a return for your espresso machine or grinder please contact home.usa@lamarzocco.com.

I'm local to Seattle, am I able to pick up my order? +

Yes, absolutely! Please allow us to confirm when your order is ready for pick up.

Why does customizing a machine make it non-ETL certified? +

All of our products are tested and ETL certified under their stock configuration. By changing out the exterior materials it changes the model that was approved. Technically changing the exterior materials does not change the internal components that were approved, but since it is no longer the exact ETL model we can not say it is ETL certified. This has no affect on the home user since ETL is used purely for consumer confidence. If you have more specific questions about this, please e-mail us at home.usa@lamarzocco.com

What options do you have for shipping? +

La Marzocco Home offers free shipping for any order over $50. We don’t currently ship outside the United States. In order to fulfill all of our orders we use two different shipping methods.

XPO Logistics

For any espresso machine order, we ship using XPO Logistics. In order to better estimate how long a Freight shipment will take to get to your residence view the XPO Logistics Transit Time Calculator.

When receiving a freight shipment it is important that you are available to be home to receive the delivery. You must inspect the machine for damage before signing the paperwork. Once you sign the paperwork you are responsible for any damage that may have occurred in transit. Make sure that you note any damage that you find on the delivery receipt. View our guide to receiving freight packages here.

What is an expansion valve, and how do I set it? +

The expansion valve on your espresso machine sets the peak pressure in your brew boiler.. Our machines are set to a peak pressure of 12-bar on bench (this is not to be confused with brew pressure which is set on the pump itself). However, in the process of preparing our machines for shipment, the expansion valve must be loosened. Although we set them back via a witness mark, the end user will often need to make small adjustments to the valve. If you notice that your expansion valve is set too high or low, please refer to the Operating Manual of your machine for instructions on how to adjust.

Please reach out to Christopher Scott for any and all questions about adjusting your expansion valve, or any other technical questions that you may have

How do I set my brew temperature? +

To set the temperature on the GS3, press and hold the continuous flow (Fn) button while pressing the + (plus) button.

Linea Mini

To set the temperature on the Linea Mini, simply move the temperature wheel on the left side of the body panel to your desired temperature. Each click is equal to .3 degrees F, and the temperature displayed on the very bottom (6 o’clock on the face of the dial) of the temperature wheel, is the temperature the boiler will heat to. See the Linea Mini user guide.

What’s the deal with water, and why does it matter? +

The water you put into your espresso machine is incredibly important, and goes far beyond brewing good coffee. Putting good, clean water into your espresso machine will extend the life of your machine, and can help your machine continue to run well for years to come.

We put together a Blog Post that serves as a simple introduction to the world of water—how it affects your coffee, why it matters for your machine, and what you should do about it.

In fact, most of the problems people experience with their machines stem from the fact they are using water that is outside of the specification given by La Marzocco for proper operation. Each of our machines ship with a water test kit so that you can make sure the water you are using is within spec. View our Water Specifications and enter the results of your test in our Water Calculator.

How do I maintain my La Marzocco? +

Using proper water is paramount to keeping your machine running properly—be sure you’re using water within our specifications!

Beyond that, maintaining your La Marzocco Espresso Machine is simple. We recommend a cleaning routine at least once a week.

Settling into a regular cleaning schedule can help keep your machine clean and will go a long way in keeping it running smoothly throughout its lifespan. We like to backflush the machine with detergent and a blind portafilter, clean the portafilter, screens, and baskets all at the same time. This will help keep your espresso tasting crisp and clean, and won’t get in the way of great tasting coffee.

Check out our handy “How to Clean Your Espresso Machine” video to see it in action.

How do I make Espresso? +

Espresso is a coffee-brewing method that uses pressure to force water through finely-ground coffee. The resulting beverage is an espresso.

What you’ll need:

  • Whole Bean Coffee
  • Grinder
  • Tamper or Distribution Tool
  • Scale
  • Espresso Machine (temperature between 195° – 205°)

Every coffee is different. That’s part of the joy of making espresso! No matter how much you know, dialing in a new coffee and pulling a shot is a constant pursuit. When you put a new coffee into your grinder hopper, it’s a good idea to have a target brew ratio in mind—that is, how much ground coffee you’ll put in the portafilter and how much liquid espresso you’ll brew into the cup.

Brew ratios balance three important variables: ground coffee (in), liquid espresso (out), and brew time. A good starting place for a new coffee is a 1:2 ratio in 25-30 seconds at 200 degrees. From there, you can adjust as needed.

Check out our “How to Make Espresso Post” over on the Blog for more. Also, feel free to drop us a line if you have questions—we love nerding out about espresso!

How do I steam milk? +

Steaming milk is a combination of steam pressure, positioning of the steam wand, and knowing what to look, feel, and listen for. With a high-powered steam boiler, little changes to your milk steaming technique can make a huge difference. Practice and attention to detail truly do make perfect. We put together a quick video tutorial to help out— in it, we go through the basics of steaming milk, including positioning, timing, and what to look and listen for during the process.

What should my espresso taste like? +

First and foremost, it should taste *good.* But what does that mean? Every coffee is different, but there are some common themes you can use when tasting espresso to help you identify what you like.

First, try to identify what the body of your espresso is like. Is it thick and syrupy? Is it light and airy?  From there, when we taste espresso, we’re looking for balanced taste. Rather than trying to identify specific tasting notes on the first go-round, we try to identify the combination of bitterness, sweetness, and acidity present in our espresso.

We worked with Meister to put together an illustrated guide to tasting espresso. Check it out to see if it helps!

How do I dial-in a new coffee? +

Maybe you got a new grinder, changed your burrs, or you just got a brand new bag of coffee that you’ve never tried. Where do you start? Instead of just winging it, we put together this quick guide to help you get dialed in for espresso in a timely and efficient manner. Plus, we added a few tips & tricks that we’ve learned over the years. Whether you’re a seasoned home barista (and don’t need the help) or you’re just getting started, this quick guide will walk you through the process of dialing in.

If you don’t feel like reading our Dialing In Post, a good place to start is with a target Brewing Recipe (Brew Ratio, Time, Pressure, and Temperature).

What’s a brew ratio? +

There are quite a few variables that we’re looking to control and balance at one time in order to get the best possible taste out of a coffee. Understanding these variables comes with time and practice, but one of the most important variables we need to control is also one of the easiest: brew ratio.

When we talk about brew ratio, we’re talking about the weight of coffee grounds to the weight of espresso in the cup. By changing the weight of coffee or the weight of liquid espresso in a shot, we can manipulate the taste and mouthfeel of the espresso.

Measuring brew ratio is pretty easy with a scale, and doesn’t require much practice (we recommend a scale that measures to the .1 g). Using a scale, we can easily and consistently measure the weight of ground coffee that goes into the portafilter, as well as the weight of the liquid espresso that ends up in the cup.

A brew ratio consists of your ins (ground coffee) to your outs (liquid espresso), and it’s always a good idea to plug your preferred brew ratio (ristretto, normale, lungo) into a larger brewing recipe.

Here’s a good place to start:

Brew Ratio: 1:2

In: 18g

Out: 36g

Time: 30s

Temperature: 200 F

Pressure: 9 bars
