Sage Dual Boiler

Dual Boiler maintenance, organised around the jobs that matter.

Dual-boiler maintenance needs more care than a simple thermoblock machine: coffee-oil cleaning, water filtration, steam hygiene and the dedicated boiler-drain descale procedure should stay separate.

Maintenance schedule

The useful baseline for your Dual Boiler.

Use the machine’s own prompt sooner whenever it asks for maintenance. Water hardness and usage can also change the practical timing.

After use

Group & steam hygiene

Flush the group, rinse the basket and purge/wipe the steam wand.

Regularly / CLEAN ME

Cleaning cycle

Run the detergent cleaning cycle with the Sage cleaning disc and tablet.

About 3 months / by filter

Water filter

Replace the correct cartridge for the machine batch.

As required

Descaling

Use the dedicated dESC procedure only; the boilers must be cooled and drained in the specified sequence.

Personalise this schedule

Want Ventori to remember the Sage Dual Boiler maintenance rhythm for you?

Your machine is already selected. Add local water hardness and typical use without choosing the manufacturer or model again.

Coffee-oil cleaning

Run the Dual Boiler CLEAN ME cycle.

This cleans coffee oils from the group system and is separate from boiler descaling.

Understand this care task →
01

Fit the correct basket and cleaning disc

Use the Sage cleaning disc or insert supplied for your machine.

02

Add one suitable cleaning tablet

Place the tablet in the cleaning disc or basket exactly as the machine procedure shows.

03

Start the cleaning programme

Use the machine prompt, touchscreen menu or model-specific button sequence.

04

Let the full cycle finish

Do not interrupt the pressure and rinse stages once the programme is running.

05

Rinse the brew parts

Remove and rinse the portafilter, basket and cleaning disc before making coffee again.

Water care

Check the batch before choosing a replacement filter.

Older BES920 production runs can use a different filter arrangement; current ClaroSwiss compatibility begins at the Sage batch cut-off.

Understand this care task →
01

Check filter compatibility

Older Dual Boiler and Oracle production runs can use a different filter arrangement, so check the batch/holder before ordering.

02

Soak the replacement

Prepare the current ClaroSwiss cartridge using the filter instructions before fitting it.

03

Fit it securely

Install the prepared cartridge into the holder and lock the holder into the water tank.

04

Track the replacement

Use the machine reminder or installation date so the next change is not missed.

Dual-boiler scale care

Treat the boiler-drain descale as a model-specific service procedure.

The Dual Boiler descale process requires the machine to cool, both boilers to be drained through the descale access valves, a timed solution stage, and repeated fresh-water flushing. Do not substitute a generic espresso-machine descale sequence.

Understand this care task →
01

Cool the machine fully

Switch off and allow the machine to cool before opening the descale access area.

02

Use dESC mode

Enter the model-specific descale mode rather than manually pumping solution through the group.

03

Drain both boilers in the specified order

Follow Sage’s right/left valve procedure and use a cloth and empty drip tray to manage hot residual water safely.

04

Run the solution soak

Use the programme’s timed descaling stage with the correct solution volume.

05

Repeat the fresh-water flush

Rinse, refill and complete all boiler-flush stages before returning the machine to use.

Milk hygiene

Keep the steam tip clear after every milk session.

Milk residue should never be allowed to dry into the steam-tip holes.

01

Purge before milk

Run a short purge before texturing milk.

02

Wipe immediately

Wipe the wand with a clean damp cloth while milk residue is still soft.

03

Allow the purge

Where the machine has automatic purging, return the wand to its normal position and let the purge finish.

04

Clear the tip when needed

Use the supplied cleaning tool or the exact Sage cleaning method if the steam holes become restricted.

MODEL-SPECIFIC CHECK

Use the exact procedure for your machine.

Use the exact model guidance if your controls or prompts differ from this guide.

Relevant Ventori care

Match the maintenance product to the job.

Backflush cleaner belongs in the CLEAN ME coffee-oil cycle. Descaler belongs only in the dedicated dual-boiler descale procedure.
