What to do, and how often

Job How often The manual’s sentence
Backflush (detergent) When the CLEAN ME light illuminates

“The CLEAN ME light will illuminate when a cleaning cycle is required.”

“If the hole(s) remain blocked, dissolve a cleaning tablet in hot water and soak filter basket and portafilter in solution for approx. 20 minutes.”
Built-in grinder burr clean Only if there is a blockage

“This step is only required if there is a blockage between the grinding burrs and the grinder outlet.”
Descale Every 2 months

“It is recommended to descale your unit every 90 days when water hardness is at level 4; and when water hardness is at level 6, descale your unit every 60 days.”
Drip tray empty & clean At regular intervals, particularly when EMPTY ME! shows

“The drip tray should be removed, emptied and cleaned at regular intervals, particularly when the drip tray full indicator is showing EMPTY ME!”
Group gasket replacement Over time

“Over time, the silicone seal surrounding the shower screen will need to be replaced to ensure optimum brewing performance.”
Group head wipe / flush No interval given

“The group head interior and shower screen should be wiped with a damp cloth to remove any ground coffee particles.”

Notes from the research
  • Cites Sage's BES875 quick guide, which is Sage's current code for The Barista Express. No Sage-hosted BES870 English manual was found (the sageappliances.com BES870 path 404s). The Breville BES870XL manual is cited as s2 for contrast.
  • Descale hardness bands are in Sage test-strip levels (4 → 90 days, 6 → 60 days) with no published °dH mapping, so every_by_hardness could not be filled.
  • Sage (UK BES875) and Breville (US BES870XL) manuals differ for the same machine: filter 3 months/40 L vs 2 months; descale by hardness with no prompt vs on the CLEAN / DESCALE light. This record follows the Sage manual.
  • No interval for the routine grinder burr clean, group wipe, purge, or seal replacement.
  • Burr replacement life, shower screen replacement and a service interval are not stated by Sage/Breville.
  • The water filter cartridge is not named in the manual.
