Daily Maintenance and Care for the Sm85e Espresso Machine

If you use an Sm85e espresso machine daily—whether at home or in a café—you’ve likely wondered how to keep it running smoothly and tasting great. Beyond just turning it on and off, proper maintenance ensures consistent espresso extraction, protects expensive components, and prevents costly repairs. This guide covers everything you need to do, step by step, to maintain your Sm85e like a pro.

In short: Daily, check water pressure and clean the group heads. Twice a week, backflush with detergent. Every six months, replace group gaskets, regenerate the softener, and drain the internal water tank. Always avoid washing the grinder with water.

Daily Espresso Machine Checks

Start each day by confirming the machine’s water pressure is within normal range. Never use the Sm85e if there has been a water outage—even briefly. This protects the boiler and pump from dry firing or damage due to air ingress. Pressure stability is essential for consistent shot quality.

Cleaning the Group Heads

Every day, thoroughly clean the machine’s group heads. This removes old coffee oils, grounds, and residue that build up and degrade taste. Then, twice per week, perform a backflush with dedicated espresso machine cleaning powder. Follow the instructions printed on the cleaner’s package—typically involving running cycles with the cleaner, then rinsing. Soak your portafilter baskets and handles in the cleaning solution for one hour to break down embedded oils.

Six-Month Maintenance Tasks

Every six months, complete several key maintenance steps to extend machine life:

• Replace the group head gaskets to maintain a tight seal and prevent leaks.
• Regenerate the built-in water softener—this involves adding salt, soaking for 40 minutes, draining until water runs clear of salt taste, then flushing for five more minutes before returning to normal operation (see

  

  and

  

  ).
• Drain all internal water from the machine and refill with fresh water to prevent stagnation and bacterial growth.

How to Drain the Machine Safely

To drain the Sm85e:

1. After turning off the machine and releasing steam, remove the drip tray.
2. Open the valve located in the red-marked area (as shown in an image) to let water escape. Opening the steam wand during this speeds up drainage.
3. Once fully drained, close the valve and manually refill the water tank for about two minutes to initiate the automatic water replenishment cycle.
4. Finally, switch the power to “1” to allow the machine to finish refilling before shutting down.

This process clears old water and ensures the boiler and lines are replenished with fresh water for the next use cycle.

What to Avoid

Never wash the grinder component of the machine with water, and do not allow water to enter the bean hopper. Moisture damages the burrs and dosing mechanisms, leading to inconsistent grind and possible motor issues. Keep the grinder dry and clean with a brush only.

Frequently Asked Questions

How often should I backflush my Sm85e espresso machine?

Backflush with espresso cleaning powder twice a week. Use the manufacturer’s recommended dosage and follow the instructions on the cleaning product packaging. After backflushing, soak the portafilter basket and handle in the cleaning solution for one hour to remove coffee oils and residue.

What should I clean daily on my Sm85e machine?

Each day, check that the water pressure is normal and clean the group heads thoroughly. This prevents buildup of old coffee oils and ensures a clean extraction every time you pull a shot.

How do I regenerate the softener in the Sm85e?

Every six months, add salt to the softener, soak it for 40 minutes, then let the water run until it is free of salt taste. Continue running water for an additional five minutes before switching back to normal operation mode.

Do I need to drain the water from the Sm85e regularly?

Yes. Every six months, completely drain the internal water tank and lines, then refill with fresh water. This prevents stagnant water and keeps the internal plumbing clean.

Can I wash the grinder in the Sm85e with water?

No. Do not wash the grinder or let any water enter the bean hopper. Water damages the grinding burrs, doser, and internal electronics. Clean the grinder using only a brush.
