Descale your Sage Oracle

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 if you have hard water.

Before you begin

You will need:

Ventori Descaling Tablets
Fresh Water
A jug to collect water

Step 1 - Placing a container to collect the soltuion

Step 2 - Start the Descaling Cycle

Rotate SELECT dial until 'dESC' appears on the LCD and press the dial to confirm.

Step 3 - Empty Boilers

Remove the grey silicone cover. Place a cloth over the drip tray to prevent steam escaping. Using a flat head screwdriver rotation the right valve counter-clockwise slowly until fully open. Once the water has drained, rotate the screw clockwise to close the valve.

Repeat the above process on the left valve.

Step 4 - Remove the Water Tank

Remove the water tank from the machine and empty any remaining water

Step 5 - Remove the water Filter

If, fitted, remove the ClaroSwiss BES008 filter before descaling.

STEP 6 - Preparing the Descaling solution

Dissolve the recommended number of descaling tablets in warm water

Step 7 - Fill the water tank

Fill the water tank with the prepared descaling solution

Step 8 - Prepare the Machine

Replace the water tank into the machine. Position a large container beneath the outlets.

STEP 9: Start the descaling

Press the 1 CUP button and the LCD screen will show countdown time (20 minutes). During this time, the machine will fill boilers with descale solution and heat. There may be some water flow through the group head. Allow the countdown timer to reach 0.

STEP 10: Flush the boilers

Press the 1 CUP Button and the LCD screen will countdown time (20 minutes). Place a cloth over the drip tray. Complete STEP 3 again to empty the boilers.

Empty the water tank and rinse and fill with clean water

STEP 11: Repeat Step Flush Boilers

It is recommended to flush boilers again to remove any residual descale solution.

Press POWER button to escape the Descale mode.

Step 11 - Enjoy better coffee

Sage ClaroSwiss BES008 Water Filter

The Sage Oracle uses the Sage ClaroSwiss BES008 water filter. Replacing it approximately every 3 months helps reduce limescale, improve water quality and maintain coffee flavour.

Remember, a water filter helps reduce scale build-up but does not replace regular descaling.

Backflush the Brew Group

The Sage Oracle uses a three-way solenoid valve, which means coffee oils build up inside the brew group over time. Regular backflushing helps maintain espresso flavour, improve extraction and keep the machine operating.

When the CLEAN ME light is illuminated, the machine requies a cleaning cycle.

Before you begin

You'll need:

Blind basket
Ventori Backflush Tablets
Group Handle

Step 1: Fit the blind cleaning disc

Insert the 1CUP filter basket into the portafilter followed by the supplied cleaning disc.

Step 2: Add the tablet

Add one backflush cleaning tablet to the portafilter basket

Step 3 Lock the portafilter into the group head

Lock the portafilter into the group head and place a large container under the group head. Ensure the water tank is filled with cold water

Step 4: Start the cleaning cycle

Press the MENU button and rotate the SELECT dial until CLEAN CYCLE and PUSH are displayed on the LCD. Press the SELECT dial to start the cleaning cycle

STEP 5: During the Cleaning cycle

During the cleaning cycle, the LCD will displace a countdown timer showing remaining time in seconds.

STEP 6: Rinse the brew head

Once the tablet has completely dissolved, remove the portafilter and rinse the brew head from cleaning solution. Wipe off any splashes of water from the machine with a soft dry cloth.

Ventori Tip: Don't confuse descaling with backflushing.
Descaling removes mineral limescale from the water circuit.

Backflushing removes coffee oils from the brew group.

Both are essential for great espresso.

Clean the Steam Wand

Milk residue can quickly build up inside and around the steam wand. Purging and wiping the wand after every use helps maintain steam performance, improves milk quality and prevents blockages.

Recommended: After every use.

Step 1: Purge the steam wand

Purge the steam wand for 2–3 seconds before cleaning.

Step 2: Wipe the steam wand

Wipe the steam wand immediately after use to remove milk residue.

Step 3: Purge again

Purge the steam wand again to clear any milk from inside the tip.

Step 4: Clean the steam tip

If the steam tip becomes blocked, remove and clean it before refitting.

Step 5: Enjoy perfectly steamed milk

Your steam wand is now clean and ready for the next use.

Why Clean Your Steam Wand?

Regular cleaning helps to:

Prevent milk residue from drying inside the wand
Maintain consistent steam performance
Produce smoother microfoam
Reduce blocked steam tips
Improve hygiene and milk quality

Ventori Tip: Purge the steam wand before and after steaming milk, then wipe it immediately with a clean, damp cloth while it's still warm.

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.

Step 1: Empty the bean hopper

Remove the remaining beans and store them in a clean container.

Step 2 – Remove the Upper Burr

Unlock the hopper and lift out the upper burr using the wire handle.

Step 3 – Brush Away Coffee Residue

Brush away coffee oils and grounds from the burr and grinder chamber. Do not use water.

Step 4 – Reassemble & Brew

Refit the upper burr, lock it into place, replace the hopper and enjoy fresh espresso.

Why Clean Your Grinder?

Regular cleaning helps to:
Maintain consistent grind size
Improve coffee flavour
Remove stale coffee oils
Reduce grinder blockages
Extend grinder performance

Ventori Tip: A soft brush is all you need for routine cleaning. Avoid using water inside the grinder.

Sage Oracle FAQs

How often should I descale a Sage Oracle?

The ideal descaling frequency depends on your water hardness. As a general guide:

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 noise from the pump, descaling may be required sooner

How often should I backflush a Sage Oracle?

Backflushing should be performed approximately once per week using a cleaning tablet and cleaning disc. Regular backflushing helps remove coffee oils and brewing residue from the group head and internal pathways

What does the Clean Me light mean on a Sage Oracle?

The Clean Me indiciator is a maintenance reminder that signals when a cleaning cycle should be performed. When the light appears, run the cleaning cycle according to Sage's instructions using a cleaning tablet and cleaning disc.

Does the Sage Oracle use a water filter?

Yes. The Oracle can use a Sage ClaroSwiss water filter fitted inside the water tank. Replacing the filter approximately every 3 months helps reduce the limescale build-up and improve water quality.

Can limescale affect espresso quality?

Yes. Limescale can reduce temperature stability, restrict water flow, and affect extraction consistency. Regular descaling helps maintain espresso flavour and machine performance.

What are the signs my Sage Oracle needs maintenance?

Common warning signs include:

Slower water flow
Reduced steam performance
Increased pump noise
Inconsistent espresso extraction
Visible scale deposits
Longer heat-up times

These symptoms often indicate that cleaning, descaling, or filter replacement may be required.

How long does Sage Oracle maintenance take?

Most routine maintenance is quick:

Daily cleaning: 2 - 3 minutes
Weekly backflush: 10 - 15 minutes
Descaling: 30 - 60 minutes
Water filter replacement: approximately 5 minutes

How can I make my Sage Oracle last longer?

Regular maintenance is the best way to extend the lift of your machine. Daily cleaning, weekly backflushing, water filter replacement, and descaling based on water hardness help preserve espresso quality, steam performance, and long-term reliability

Why is my Sage Oracle grinder clumping?

Coffee oils and humidity can cause grounds to clump. Regular cleaning of the grinder chute and butt area helps maintain consistent grinding performance.
