Check the nozzle for clogs

One of the most common reasons for steam not coming out of your La Marzocco coffee machine is a clogged nozzle. This issue can occur when milk proteins build up on the nozzle over time, blocking the steam flow. Here’s what you can do to address it:

Remove the nozzle from the steam wand.
Soak the nozzle in hot water and vinegar for a few hours to dissolve any buildup.
Use a needle or toothpick to carefully clean any remaining debris from the nozzle’s tiny holes.

Check the steam pressure on the left gauge

Another potential cause of steam not coming out of your La Marzocco coffee machine is insufficient steam pressure. To troubleshoot this issue, follow these steps:

Check the left pressure gauge on your machine to see if it’s within the recommended range of 1.5-2 bar.
If the pressure is too low, adjust it using the machine’s steam valve control or consult your machine’s manual for guidance.

Ensure the main switch is in position I

It’s easy to overlook the machine’s main switch, but if it’s not in the proper position, you won’t get steam from your La Marzocco coffee machine. Here’s what you should do:

Check the main switch position and make sure it’s in position I.
If the switch is in position 0, flip it to position I.

Check the connection to the mains

In some cases, the issue with your La Marzocco coffee machine may be due to a faulty connection to the mains. Here’s how to troubleshoot this issue:

Ensure that the machine’s power cord is securely plugged into a working outlet.
Verify that the outlet is functioning correctly and that the circuit breaker hasn’t been tripped.
Check the machine’s fuse and replace it if it’s blown.
