Backflush (water) 30 s at the end of any day the machine is used (twice a week at minimum)

Shower screen replacement Every year

“Replace the group gasket and shower screen yearly, but you can dismount the group gasket and shower screen to clean the underside of the group head as often as you'd like.”

Notes from the research
  • The X58's own manual (Clive) covers only water; every group-cleaning value comes from Clive's generic E61 care guide, which does not name the X58.
  • The record's brand is Quick Mill but every source is Clive's (the LUCCA brand owner); the published basis depends on clivecoffee domains being allowlisted for this record.
  • Group head wipe, steam wand, drip tray, water tank, boiler water change and professional service are not stated.
