What to expect, what’s normal, and a few things that will make your first month of home espresso a little easier.

The Quick Q&A: Common First-Month Questions

My Linea Micra’s red and blue lights are flashing. What’s wrong?
If this happens during initial setup, your machine hasn’t completed its startup process. Fill the reservoir all the way with recommended water and follow the startup guide to finish priming the machine.

Why isn’t my machine recognizing the water?
Your water may not contain enough minerals for the machine’s sensor to detect it. Check that your water meets La Marzocco’s requirements.

Why is my portafilter so tight?
A new grouphead gasket takes time to break in. As long as the portafilter seals without leaking, it doesn’t need to lock in perfectly centered.

Why does my espresso taste or pull differently every time?
Start by weighing your coffee dose and espresso yield. Keep those consistent while adjusting your grind size to control how quickly the espresso flows. It actually takes practice to get things consistent and remember that the equipment will take some time to break in as well. 

Is a wet coffee puck a bad thing?
Not necessarily. A wet puck doesn’t mean your espresso is bad. Focus on how your espresso tastes rather than how the puck looks.

Why is the steam wand so powerful?
La Marzocco machines have professional steaming power and that means the milk will heat up quick. You can adjust the steam setting on the Linea Mini and Linea Micra through the app and practice controlling foam by changing the wand’s position in the milk.

Are all these machine noises normal?
Most heating, pump, and valve sounds are part of normal operation. If something sounds unusual or continuous, send the La Marzocco Home team a video so we can help.

Welcome to Your First Month

Bringing home a La Marzocco is exciting. You’ve got a beautiful new espresso machine sitting on your counter, fresh coffee ready to grind, and plenty of drinks you can’t wait to make. But once you start using your machine, you might find that there’s a little more to learn than you expected.

Even if you’ve worked as a barista or owned another espresso machine, getting familiar with a La Marzocco at home can take some practice. The equipment is powerful, the workflow might be new, and making consistently great espresso is a skill that develops over time.

Here are some of the most common things we hear from new owners, along with a little guidance to help you get comfortable with your machine.

Getting Through the First Startup

“My Linea Micra has flashing red and blue lights. What’s happening?”

If the red and blue lights on your Linea Micra are flashing back and forth during your initial setup, it means the machine hasn’t completed its startup process.

Starting up the Linea Micra

To complete the process, fill the water reservoir all the way up, then move the brew paddle to the brewing position. Allow water to flow from the grouphead until the machine stops the process on its own, which should take about 10 seconds. Return the paddle to the off position and allow the machine to heat up.

“What about starting up a Linea Mini or GS3?”

Every La Marzocco machine has a slightly different startup process. On the Linea Mini, the machine fills its boilers automatically once it’s turned on, and you’ll need to allow time for it to heat up and flush water through the group according to its startup instructions.

If you have a GS3, there’s an additional step called bleeding the group, which is especially important during the machine’s first startup. This process releases air trapped inside the brew boiler and replaces it with water, ensuring the group is properly filled before you begin brewing.

Every La Marzocco machine comes with a startup guide specific to that model, so keep it nearby while you’re unboxing and setting everything up. Taking a few minutes to follow the correct instructions will help you avoid unnecessary troubleshooting and get your machine ready for its first espresso.

“My machine isn’t recognizing the water in the reservoir.”

This can happen when the mineral content of your water is too low for the machine’s water-level sensor to detect.

Water is one of the most important parts of owning an espresso machine, both for the espresso you make and the long-term health of your equipment. Not all filtered or bottled water is suitable for a La Marzocco, and water that’s too low or too high in certain minerals can cause problems.

There are a couple bottled water options that meet La Marzocco standards:

Poland Springs (on the east coast)
Crystal Geyser (if it is bottled in California or South Carolina – check the label)

Getting Comfortable With Your Equipment

“My portafilter feels really tight and doesn’t lock in perfectly centered.”

That’s common with a brand-new machine!

The gasket inside your grouphead is new and hasn’t had time to break in. Because of this, your portafilter may feel tighter than expected or stop a little short of the centered position.

As long as your portafilter creates a proper seal without leaking, there’s no need to force it into a perfectly centered position. With regular use, the gasket will begin to settle, and locking in the portafilter should become more comfortable.

“My espresso tastes or looks different every time.”

Welcome to dialing in espresso!

One of the biggest adjustments for a baristas is learning how much grind size affects the way espresso flows through the coffee and with professional equipment this is intensified.

If your shot runs too quickly, you may need to grind finer. If it’s moving too slowly, try grinding a little coarser. But before you start making adjustments, it’s important to know how much coffee you’re using and how much espresso you’re getting out.

This is where a scale becomes one of your most useful tools.

Start by weighing your ground coffee going into the portafilter, then weigh the espresso coming out. Keeping these measurements consistent gives you a reliable starting point for making grind adjustments.

Without knowing your dose and yield, you’re trying to solve an espresso problem without all the information.

A shot time of around 25–35 seconds, measured from the moment you activate the brew paddle, can be a useful starting point for many coffees. From there, let taste guide your adjustments.

And remember, coffee changes as it ages. Even after finding a recipe you love, you will need to make small adjustments over time.

“My coffee puck looks wet after pulling a shot. Is something wrong?”

A wet or soupy puck doesn’t automatically mean you’ve made a bad espresso. Different coffees, grind sizes, doses, and basket sizes can all influence how much water remains in the coffee after brewing.

It’s easy to become focused on how the puck looks, but the most important thing is what’s happening in your cup.

If your espresso tastes balanced and you’re happy with the result, there’s usually no reason to worry about a little extra moisture in the puck.

Learning to Steam Milk

“The steam wand is much more powerful than I expected.”

La Marzocco machines have serious steaming power, and it can take a little practice to get used to it, especially if you’re coming from a smaller home espresso machine.

On the Linea Mini and Linea Micra, you can adjust the steam power through the La Marzocco Home app to make the learning process a little more manageable.

A great way to understand milk steaming is to practice making two different textures: one with plenty of foam and one with very little.

The position of the steam wand makes a big difference. Keeping the tip close to the surface of the milk introduces air and creates foam. Once you’ve added the air you want, positioning the tip slightly deeper helps circulate the milk and develop a smoother texture.

Try experimenting with these two techniques until you begin to recognize how the milk responds.

It takes practice, but once you understand how to control the steam, making beautifully textured milk becomes much easier.

Getting to Know the Sounds of Your Machine

“My machine makes noises I’ve never heard before. Are they normal?”

Remember, you’ve brought home a professional espresso machine.

Inside your La Marzocco are boilers, pumps, heating elements, and valves that work together to prepare your espresso and produce steam. This means your machine isn’t going to be completely silent.

You may hear the boiler heating, the pump running, valves activating, or the machine maintaining its temperature and pressure throughout the day.

Many of these sounds are simply part of normal operation.

As you spend more time with your machine, you’ll begin to recognize its regular sounds and routines. If something seems unusually loud, continuous, or different from what you’re used to, don’t hesitate to reach out to the La Marzocco Home team. We’re always happy to take a look at a video and help determine whether what you’re hearing is normal.

Building Your Daily Routine

Your first month isn’t about making perfect espresso every single time. It’s about learning your equipment and building good habits.

A few simple practices will make a big difference:

  • Weigh your coffee. Measure the dose going into your portafilter and the espresso coming out.
  • Keep your portafilter warm. Leave it locked into the grouphead when the machine is on and not in use.
  • Purge your grouphead. Give it a brief flush before brewing and rinse away any remaining grounds afterward.
  • Adjust your grind. Make small changes when your espresso is flowing too quickly or too slowly.
  • Taste your espresso. Your palate is just as important as the numbers on your scale.
  • Take care of your steam wand. Purge before steaming, then wipe it clean and purge again immediately afterward.

These little routines eventually become second nature, and that’s when making espresso at home starts to feel less like a challenge and more like a part of your day.

Give Yourself Time

With every shot, you’re getting to know your machine, your grinder, and the coffee you’re using. You’ll learn to recognize how espresso should flow, how milk should feel, and when it’s time to make an adjustment.

And before long, the things that felt complicated during your first week will become part of a familiar routine. You might already be closer to making great espresso than you think. You’re just getting started.
