Add your Barista Express and keep descaling, backflushing and filter changes together, with reminders shaped around your machine, water hardness and routine.
For this machine
Products you will need
Keep the essentials on hand so routine maintenance is quick when your machine needs it.
Descaling
Descale your Sage Barista Express
Calcium and limescale naturally build up inside your machine over time. Regular descaling helps maintain brewing temperature, water flow and espresso flavour.
Recommended: every 2–3 months, or sooner in hard-water areas.
Before you begin
You will need
- Ventori Descaling Tablets
- Fresh water
- A large jug or container to collect water
Remove the water tank
Remove the water tank from the machine and empty any remaining water.
Remove the water filter
If fitted, remove the ClaroSwiss BES008 filter before descaling.
Prepare the descaling solution
Dissolve the recommended number of descaling tablets in warm water.
Fill the water tank
Fill the water tank with the prepared descaling solution.
Replace the water tank
Return the filled water tank to the machine.
Position a container
Position a large container beneath the outlets, large enough to collect the solution.
Start the descaling cycle
Press and hold the 2 CUP and POWER buttons simultaneously to enter descaling mode. The machine will illuminate the descale indicators.
Allow the solution to run through
Allow the descaling solution to move through the machine as directed by the cycle.
Rinse and refill with fresh water
Discard any remaining solution, rinse the tank thoroughly and refill it with clean water.
Flush with fresh water
Run fresh water through the machine to remove any remaining descaling solution.
Reinstall the water filter
Refit or replace the water filter before returning the machine to normal use.
Water filtration
Sage ClaroSwiss BES008 water filter
The Sage Barista Express uses the Sage ClaroSwiss BES008 water filter. Replacing it approximately every three months helps reduce limescale, improve water quality and maintain coffee flavour.
Remember: a water filter helps reduce scale build-up, but it does not replace regular descaling.
Quick information
- Filter type
- Sage ClaroSwiss BES008
- Replace
- Approximately every 3 months
- Priming
- Soak and flush before first use
- Descaling
- Still required according to water hardness
Cleaning cycle
Backflush the brew group
The Sage Barista Express uses a three-way solenoid valve, which means coffee oils build up inside the brew group over time. Regular backflushing helps maintain espresso flavour, extraction and machine performance.
Before you begin
You will need
- 1 CUP filter basket
- Cleaning disc / blind insert
- Ventori Backflush Tablet
- Portafilter
Fit the cleaning disc
Insert the 1 CUP filter basket into the portafilter followed by the supplied cleaning disc.
Add the tablet
Add one backflush cleaning tablet to the portafilter basket.
Lock in the portafilter
Lock the portafilter into the group head and place a large container below.
Start the cleaning cycle
Press the 1 CUP and 2 CUP buttons simultaneously, then press POWER. Hold all three buttons together for approximately 10 seconds.
Check the tablet has dissolved
After approximately five minutes, remove the portafilter and check that the tablet has completely dissolved. If not, repeat the cleaning cycle.
Rinse the brew head
Remove the cleaning disc, reinsert the portafilter and press the 2 CUP button to rinse away any cleaning solution. Wipe away splashes with a soft cloth.
Don’t confuse descaling with backflushing. Descaling removes mineral limescale from the water circuit; backflushing removes coffee oils from the brew group. Both matter for a well-maintained espresso machine.
After every use
Clean the steam wand
Milk residue can quickly build up inside and around the steam wand. Purging and wiping it after every use helps maintain steam performance, milk quality and hygiene.
Recommended: after every use.
Purge the steam wand
Purge the steam wand for 2–3 seconds before cleaning.
Wipe the steam wand
Wipe the steam wand immediately after use to remove milk residue.
Purge again
Purge the steam wand again to clear any milk from inside the tip.
Clean the steam tip
If the steam tip becomes blocked, remove and clean it before refitting.
Ready for the next use
Your steam wand is now clean and ready for the next use. Regular cleaning helps maintain consistent steam performance and smoother microfoam.
Purge the steam wand before and after steaming milk, then wipe it immediately with a clean damp cloth while it is still warm.
Grinder care
Clean the grinder
Regular grinder cleaning removes stale coffee oils and fine grounds that can affect flavour and grind consistency.
Recommended: every 2–4 weeks.
Empty the bean hopper
Remove the remaining beans and store them in a clean container.
Remove the upper burr
Unlock the hopper and lift out the upper burr using the wire handle.
Brush away coffee residue
Brush away coffee oils and grounds from the burr and grinder chamber. Do not use water.
Reassemble and brew
Refit the upper burr, lock it into place, replace the hopper and return the grinder to normal use.
Regular cleaning helps maintain grind consistency, improve flavour and reduce blockages.
A soft brush is all you need for routine grinder cleaning. Avoid using water inside the grinder.
Troubleshooting
Having a problem?
If your Sage Barista Express is showing signs of poor performance, start with the symptom that best matches what you are seeing.
Why is the CLEAN ME light on?
Why is my coffee not hot enough?
Why is my steam pressure low?
Why does my espresso taste bitter?
Why is my espresso pouring too fast?
Why is my espresso pouring too slowly?
Why is my machine making loud or unusual noises?
Why is my coffee machine leaking water?
Why does my espresso taste sour?

Common questions
Sage Barista Express FAQs
How often should I descale a Sage Barista Express?
The ideal frequency depends on your water hardness:
- Soft water: every 3–4 months
- Moderate water: every 2–3 months
- Hard water: every 1–2 months
If you notice slower water flow, reduced steam performance or increased pump noise, descaling may be required sooner.
Can I descale my Sage Barista Express without removing the water filter?
It is best to remove the water filter before descaling. Descaling solution can reduce the effectiveness of the filter and shorten its lifespan. Reinstall it once the machine has been thoroughly flushed with fresh water.
How many Ventori descaling tablets should I use?
Use two Ventori Descaling Tablets dissolved in warm water for one complete descaling cycle.
How often should I backflush my Sage Barista Express?
Backflush approximately once a week, or after around 25 coffees, to remove coffee oils from the brew path and maintain espresso quality.
Can I use vinegar to descale my Sage Barista Express?
Vinegar is not recommended. It can leave lingering odours, may not remove scale as effectively and can affect the taste of future coffees. Use a descaler designed for coffee machines instead.
Do I need to descale if I always use a water filter?
Yes. A water filter slows scale build-up but does not prevent it completely. Your machine will still require periodic descaling.
Why does my Sage Barista Express still show the CLEAN ME light after cleaning?
The CLEAN ME light relates to the backflush cleaning cycle, not descaling. Make sure you complete the full cleaning programme with the cleaning disc and a backflush tablet so the machine can reset the reminder.
How do I know when to replace the Sage ClaroSwiss BES008 water filter?
Sage recommends replacing the ClaroSwiss BES008 approximately every three months, or sooner if you make a high volume of coffee or have very hard water.
Can poor maintenance affect espresso quality?
Yes. Scale, coffee oils and blocked shower screens can reduce water flow, affect brewing temperature and pressure, and contribute to bitter, sour or weak espresso. Regular maintenance helps keep extraction consistent.
What regular maintenance should I do?
- Backflush regularly
- Clean the shower screen and portafilter
- Clean the steam wand after every use
- Empty and clean the drip tray
- Replace the water filter approximately every three months
- Descale according to water hardness
