Overview
A Breville or Sage espresso machine asks for two different jobs with similar-looking lights: a cleaning cycle, which removes coffee oil from the group head, and a descale, which removes limescale from the inside of the machine. People confuse them constantly, run the wrong one and then wonder why the light stays on. The first thing to settle is which job your machine is asking for.
This guide separates the two. It covers the descale on the Barista Express, the Bambino Plus, the Precision Brewer and the Barista Express Impress, and the cleaning cycle on the Barista Express and Bambino Plus.
If the machine has a fault rather than a full scale tank, the section near the end tells you how to tell. For a repair, see Breville coffee machine repair in Dubai. For other makes, there is a general guide to descaling a coffee machine.
How to descale a Breville machine: the short answer
A descale and a cleaning cycle are different. The light pattern tells you which, and the table below shows the patterns we could confirm.
Use the descaler Breville supplies or names for your model. Breville's page for the Barista Express Impress says to use the descaler packet that came with the machine.
If your tank has a filter, take it out before descaling.
Mix the descaler with water as the pack says and pour it into the tank.
A 2 litre container under the portafilter and steam wand is used for the Bambino Plus. It must be large enough for everything that comes out.
The button sequence depends on the model. The sequences we could confirm are below.
Run it through the coffee outlet, the steam wand and the hot water outlet, as your model requires.
Rinse the tank, refill it with fresh water to MAX and repeat the process to flush the solution.
Return the machine to standby and make a test shot.
The full steps, with the lights, are further down.
Descale or clean? The two jobs are not the same
Running a cleaning cycle does not remove scale, and descaling does not clean the group head. A machine that gets both on time rarely needs a repair for either.
The words people type include clean me, clean descale and clean sage barista. They are usually asking about the cleaning cycle. The sections below cover both.
Breville or Sage: the same machine, two names
Breville is the name the company uses in North America and Australia. Sage is the name it uses in the UK and parts of Europe. In Dubai you may see either badge on the same machine, depending on where it was bought. The machines are the same designs under two badges, so a Sage Barista Express and a Breville Barista Express are the same family. Searches for a Sage descaler are searches for Breville's descaler.
Model codes help. Breville models are named with a code such as BES870 or BES876 on the base of the machine or the back. Use the code to find the right instruction book, because the button sequences differ between models, and between a compact machine like the Bambino and a dual-boiler machine like the Oracle.
Which Breville do you have?
We have included steps only for the models we could confirm. For the others, the model code leads you to the right book, or you can send us the code and we will find the steps.
When to descale: the signals
A light that is cancelled is not a job that is done. Cancelling the alert silences it for now and the scale is still there. Run the programme.
What you need
Set aside about 45 minutes for a compact home machine. The descale itself takes less, but the rinses and the washing of parts add up.
Before you start
A hot machine should cool before you open it. The Bambino Plus steps ask for the machine to cool completely.
Take out the basket if the model's steps say so.
Put it back.
If one is fitted.
With the descaling solution to the line your model states.
Under the portafilter outlet and the steam wand.
On the Barista Express, the steam and hot water dials are used in the descale. Know where STANDBY is on each dial.
Do not remove or empty the tank during a Bambino Plus descale. The Breville instruction book says never to remove or completely empty the water tank during descaling.
Procedure A: Barista Express
These steps are from a published guide to the Barista Express. Check them against the instruction book for your exact code.
Fill it with the diluted solution.
Hold the 2-CUP button, then hold POWER at the same time. Wait for the POWER, 1-CUP, CLEAN/DESCALE and HOT WATER/STEAM lights to stay on solid.
Press 1-CUP.
Turn the steam dial to the right, then the hot water dial to the left. Turn a dial back to STANDBY to stop it.
About half a litre will remain in the tank. Repeat the steps to empty it.
Rinse the tank, refill it with fresh water to the maximum line, and repeat all the steps to flush the solution.
Press POWER to leave descale mode. The LEDs turn off when you are done.
If your machine's lights or button names differ from these, you have a different version. Use the instruction book.
Procedure B: Bambino and Bambino Plus
These steps are from a published guide. The Breville instruction book confirms the alert and the rule about the tank.
Empty and reinsert the drip tray. Fill the tank to the DESCALE line and add the descaling agent.
A 2 litre container under the portafilter outlet and the steam wand.
Turn the machine off by pressing 1 CUP and STEAM together, and let it cool completely.
Hold 1 CUP and STEAM together for 5 seconds.
Press 1 CUP or STEAM. The mode pauses when the solution runs out.
Fill the tank to the MAX line with fresh water, empty the waste container, and reinstall both parts.
Press either button. When the cycle ends, the machine returns to standby.
Empty the waste container, and rinse and dry the drip tray and the water tank.
The pause in step 5 is part of the programme. The machine waits for you to refill the tank, so do not read it as a fault.
Procedure C: Precision Brewer
The Precision Brewer is a filter machine, so the process resembles the filter-machine method in our general descaling guide.
Empty the tank and pour in the prepared solution.
Place the basket and an empty carafe under the drip stop outlet, with the carafe lid locked.
Hold SELECT for 3 seconds. The cycle takes about 15 minutes.
Fill the tank with fresh water and run two full brew cycles. Discard the carafe water each time and rinse the carafe between cycles.
Machines with a descale warning flash DESCALE on the screen. Finish the rinse before you brew coffee.
Procedure D: Barista Express Impress and other models
Breville's own page for the Barista Express Impress says that when the maintenance light is on, it is time to perform a descale cycle, and to use the descaler packet that came with the machine. The page shows the process in a video that runs from emptying the drip tray and the tank to a final clear-water rinse. It does not list the steps as text, and we are not going to guess a button sequence.
The cleaning cycle
The cleaning cycle is not a descale, but it is half of what the CLEAN/DESCALE and Clean Me searches are about. The two cycles below come from Breville's Bambino Plus instruction book and a retailer guide to the Barista Express.
Bambino Plus
The machine alerts after 200 extractions since the last cleaning cycle, with the 1 CUP and 2 CUP buttons flashing alternately.
Put the provided cleaning disc in the filter basket, put a cleaning tablet on the disc, and lock the portafilter into the group head.
Empty the drip tray and return it. Place a 2 litre container under the portafilter and steam wand. Fill the tank to the MAX line.
Press and hold 1 CUP and 2 CUP together for 5 seconds.
Press 1 CUP or 2 CUP. The lights flash alternately while the cycle runs.
When the cycle ends, the machine returns to ready mode. Remove and rinse the portafilter, the disc, the drip tray and the container.
Barista Express
The CLEAN/DESCALE light flashes to say a cleaning cycle is due.
Put the one-cup filter basket in the portafilter, put the cleaning disc in it, put a cleaning tablet in the centre of the disc, and lock the portafilter into the group head.
Fill the tank to the max line with cold water, empty the drip tray and switch the machine off.
Press the one-cup and two-cup buttons together, then press POWER and hold all three for 10 seconds. The cycle runs for about five minutes.
The machine beeps twice. Remove the portafilter and check the tablet has dissolved. If it has not, repeat.
The Barista Express steps come from a retailer's guide rather than Breville, so check your instruction book if your model is a later one.
Rinsing: do it twice
A published guide stresses rinsing for every model it covers. Descaler left in the machine tastes sour, and it is not meant to be drunk.
If the light will not turn off
Resetting a light without doing the job does not help. If the machine insists, it has a reason, and the reason is usually scale or oil.
Mistakes that cost money
The biggest single mistake is mixing up the two jobs. Look at the light, find your model in the table, and run the job that matches.
Routine care between jobs
Wipe the steam wand straight after milk. Dried milk blocks the holes faster than scale does and looks like a weak steam fault.
A 45-minute plan, start to finish
The times are our own estimate for a compact home machine. Your model's book gives the real figures. If the lights do not match the second row's description, stop and check the book before going on.
Cleaning disc, cleaning tablet and descaler: what goes where
Never put a cleaning tablet in the tank or descaler on the disc. They are different products for different parts of the machine.
Baskets, gaskets and the parts that wear around a Breville
Descaling cures scale. The parts below cure the faults people mistake for scale.
Our espresso machine repair page explains each of these in more depth, and the Breville repair page covers the Barista Express, Bambino and Oracle.
How often, for your kitchen
The alerts count shots, so a busy machine reaches them sooner. A calendar reminder is a good backup, because alerts can be cancelled by accident.
Breville descaler or a third-party product?
Breville names its own descaler, and the Barista Express Impress page tells owners to use the packet supplied with the machine. A published guide also lists a compatible descaling solution sold for the Barista Express, Bambino Plus and other models. Here is how to think about the choice.
Whatever you use, dilute it as the pack says and rinse it out fully. More descaler does not give a better result, and a stronger mix is more likely to harm seals.
After the descale: the first drinks
Coffee outlet, steam wand and hot water outlet, with a cup or jug under each.
It should be clean. A sharp smell means more rinsing.
Then lock in a basket of coffee and pull a real shot.
A shot that flows evenly in a normal time says the scale is gone.
Open the wand for a few seconds. The steam should be strong and dry.
Write it on a label or in your phone.
If the shot is sour, the temperature is wrong, or the steam is weak after a good descale, the cause is something else, and the technician section covers it.
Shutting a Breville down for a long absence
Water left standing in the tank and lines for weeks can leave a smell and a slow, scaled machine on your return, so empty it first.
A Breville in an office or a shared kitchen
We service Breville machines in offices across Dubai and can set up regular visits with a record sheet left beside the machine.
When descaling is not the answer: call a technician
A scaled Breville improves after a descale. If it does not, the fault is a part.
We repair Breville and Sage machines at your home or office in Dubai. The visit is AED 100 plus VAT, the repair is AED 80 to AED 400 depending on the fault, and the price is agreed before work starts. Parts are genuine and a month of cover applies. See Breville coffee machine repair, or the wider espresso machine repair page.
Frequently asked questions
How do I descale a Breville espresso machine?
Use the descaler for your model, remove the water filter, fill the tank with the solution, enter descale mode, run it through the coffee, steam and hot water outlets, then rinse with fresh water. The button sequence depends on the model.
What does the clean me light on a Breville mean?
It asks for the cleaning cycle that removes coffee oil from the group head. It is not a descale. Check your instruction book for your model.
What is the difference between Breville and Sage?
They are the same machines sold under two names. Sage is used in the UK and parts of Europe.
How do I descale a Barista Express?
Hold the 2-CUP button and POWER together, wait for the lights to stay solid, press 1-CUP, then turn the steam and hot water dials as the published steps describe. Repeat to empty the tank, then rinse.
How do I descale a Bambino Plus?
Fill the tank to the DESCALE line with the agent, place a 2 litre container under the outlets, switch off and cool, hold 1 CUP and STEAM for 5 seconds, then press 1 CUP or STEAM to start.
How often should I run the cleaning cycle?
The Bambino Plus alerts after 200 extractions. The Barista Express flashes its CLEAN/DESCALE light when a cleaning cycle is due.
Can I stop a descale halfway?
Do not remove or empty the tank on the Bambino Plus. Let the programme finish or pause as designed.
What descaler should I use?
Breville's page says to use the packet supplied with the machine. Otherwise use a descaler named for your model, and never mix products.
Can I use vinegar?
We do not recommend it. Check your instruction book, because makers differ, and some warn against it.
Do I need to descale if I use filtered water?
Yes, though less often. Filtering reduces scale but does not remove all minerals.
Why is my Breville still flashing after descaling?
The cycle was interrupted or a rinse was skipped. Run it again to the end. If it persists after a full descale, book a visit.
What is the cleaning disc for?
It blocks the basket so the cleaning cycle can hold water and tablet solution in the portafilter. Use it only in the cleaning cycle.
Can I run the cleaning cycle and the descale on the same day?
Yes, as long as you finish one and rinse before starting the other. Do not mix the products.
My Barista Express grinds but the shots are weak. Is it scale?
Not necessarily. Check the beans, the grind, the basket and the gasket first. Scale slows flow and cools the shot, but weak shots are often a worn basket or a coarse grind.
Do I descale the grinder?
No. Descaler goes through the water path. Clean the grinder with a brush and a dry cloth, in the way your instruction book describes.
How do I stop the Bambino Plus descale alert?
Pressing any of the flashing buttons cancels the alert and returns the machine to ready mode. It does not do the job, so descale soon.
Is Sage the same as Breville?
Yes. Sage is the name used in the UK and parts of Europe, and the machines are the same designs.
