SES878Exact-model care plan · checked 28 July 2026
Sage Barista Pro maintenance guide
A practical care plan for the SES878: what to clean after use, what to inspect each week and which deeper jobs should wait for the machine or manual to prompt you.
Before you start
This is an independent desk-researched routine, not a replacement for the SES878 manual. Switch off, unplug and cool the machine before removing parts. Never immerse it, force a brew unit, open electrical panels or use a chemical the manufacturer has not approved.
01After every drink
Remove the residue while it is still easy.
Milk proteins and wet coffee become harder to remove as they dry. This is the highest-value part of the routine.
- 1
Knock out the puck, rinse the basket and wipe loose grounds from the group area.
- 2
Wipe the milk wand immediately and purge it exactly as the machine manual directs.
- 3
Rinse the milk jug and leave the portafilter and basket clean and dry.
02End of the day
Do not store yesterday’s water and coffee mess.
Standing tray water, pucks and milk residue cause odour and can block small passages.
- 1
Empty and wash the drip tray and waste container; do not let wet coffee sit overnight.
- 2
Inspect the milk wand or frother for dried residue and clean the accessible parts while cool.
- 3
Wipe the body with a soft damp cloth, keeping water away from vents, controls and electrical parts.
03Every week
Reach the parts the quick rinse misses.
Use the week as an inspection point. The manual decides which parts can be removed, soaked or lubricated.
- 1
After the machine is cool, clean the basket, portafilter and accessible shower area using only methods allowed for this model.
- 2
Brush loose, dry grounds from the hopper outlet and dosing area while the machine is switched off; keep the burr chamber dry.
- 3
Check seals, tubes and trays for damage, odour or persistent leaks before the next use.
04When prompted
Let usage and water hardness trigger chemical cleaning.
Filters, coffee oils and limescale are different maintenance jobs. Run the programme designed for the job shown.
- 1
Set the correct water hardness and replace only a compatible filter when the machine or manual says it is due.
- 2
Run the exact cleaning programme with the specified tablet or cleaner; a coffee-oil clean is not a descale.
- 3
Descale only with the approved product and exact-model sequence, completing every rinse stage before brewing again.
Model-specific cautions
What changes for the Barista Pro.
- Treat the screen prompts as the trigger for the machine cleaning cycle and filter replacement, then complete every rinse stage.
Care kit
Keep the right tools together.
The safest kit is small. Check every chemical and filter against the exact model before ordering.
- Two clean microfibre cloths: one for milk, one for the body
- A soft brush reserved for dry coffee grounds
- The exact machine’s approved cleaning tablets or powder
- Manufacturer-approved descaler and a large rinse container
- The approved milk-system cleaner if the manual requires it
- A compatible water filter, if this model uses one
