How to Maintain and Clean a Nova Coffee Machine

Worried your home espresso machine isn’t pulling shots like it used to? One of the most common issues with semi-automatic machines like the Nova is poor maintenance leading to clogged brew paths, stale water, and worn gaskets. These problems don’t just hurt espresso quality—they shorten the machine’s lifespan.

To keep your Nova running smoothly, you’ll need to clean the brew group daily, backflush weekly, replace gaskets yearly, and refresh the water system regularly. This guide walks you through the essential daily, weekly, and long-term maintenance steps with exact timing and procedures.

Daily Maintenance for Your Nova Coffee Machine

Start every day by checking the water pressure—never use the machine if the water supply is off. The brew group (or group head) must be cleaned after each use. Residual coffee oils and grounds build up quickly and will degrade taste and function if not removed daily.

Here’s your minimum daily routine:

• Check that water flows properly at startup; do not operate the machine if there’s no water supply.
• Clean the brew head thoroughly after every shot.

Weekly Cleaning: Backflushing & Soaking Portafilters

At least twice a week, you should perform a more thorough cleaning using espresso machine cleaner powder (commonly called backflushing detergent). This removes built-up coffee residue inside the brew group that normal wiping can’t reach.

Follow these steps:

• Use the dedicated cleaning powder included with your maintenance kit (refer to Diagram 1 in the manual).
• Backflush the brew group using the cleaner powder—run cycles without a coffee puck to flush internal pathways.
• Soak the portafilter and basket in a solution of the same cleaner mixed with water for one hour. This breaks down oils trapped in the fabric of the coffee filter and basket.

Long-Term Maintenance: Gaskets, Water System, and Seasonal Care

Your Nova coffee machine also needs less frequent but equally vital attention to parts that wear over time or interact with water quality. These include the brew group gaskets, water softener, and internal water reservoir.

Every six months, reset or “regenerate” the water softener (see Diagram 2). This ensures the machine’s internal water remains balanced and doesn’t damage heating elements or internal pipes over time.

Every year, replace the brew group gaskets. These rubber seals harden and leak as they age, leading to pressure loss and inconsistent extractions.

On a monthly basis:

• Drain all old water from the machine’s internal tank.
• Refill with fresh, cold water—do not use water from the grinder compartment or rinse the bean hopper.
• Important: Never put water in the bean container or run water through the grinder.

For the water softener reset procedure:

• Add salt to the softener system as directed, then soak for 40 minutes.
• Run water until it is completely free of salty taste (as shown in Diagram 3).
• After ensuring the water is clear, run the system for an additional five minutes before switching back to normal operating mode (refer to Diagram 2).

Frequently Asked Questions

How often should I backflush my Nova coffee machine?

You should backflush your Nova machine with cleaning powder at least twice a week. This removes coffee oils and residues that build up inside the brew group and affect both taste and performance. Always follow up by soaking the portafilter and basket for one hour in the same cleaning solution.

What cleaning products should I use for my Nova?

Use the manufacturer-recommended cleaning powder specified for espresso machine backflushing. Refer to the instructions included in the cleaning powder packet, particularly Diagram 1, for the proper dosing and usage steps. Do not substitute with dish soap or other cleaners.

How do I reset or regenerate the water softener in the Nova?

Every six months, add salt to the softener unit, soak it for 40 minutes, then run water until it is no longer salty. Once the water is clear, continue running it for five more minutes before returning to normal operation. See Diagram 2 and Diagram 3 for visual guidance.

Do I need to change the brew group gaskets?

Yes. The Nova’s brew group gaskets should be replaced once a year. Over time, these rubber seals harden, which can lead to leaks, pressure inconsistencies, and poor extraction quality.

Can I rinse the bean hopper or put water in the grinder?

No. Never rinse the bean hopper or put water inside the grinder. The only water you should use is fresh, clean water added to the machine’s internal tank—and even then, you must drain the old tank water monthly.
