Maintain stage
Cleaning Tablets — illustrated reference plate
Specification
What it doesDissolves into a detergent solution that is backflushed through the group head, breaking down the coffee oil and residue a brush cannot reach.
Not dish soapHousehold detergents foam under pressure and can damage the machine. Use a product made for espresso equipment.
DoseUsually one tablet or one scoop per backflush cycle, in a full blind basket of water.
CycleRun the pump in short bursts, let it soak, then repeat, then flush with clean water several times.
FrequencyWeekly for a busy home machine, monthly for occasional use.
Seals and gasketsRepeated detergent backflushing is hard on gaskets over years. Follow the machine manual for the interval it expects.

Overview

Concentrated tablets of espresso-machine detergent, used with a backflush disc to strip coffee oil out of the group head and the solenoid behind it.

Espresso
Safety

Machine detergent is caustic. Do not handle tablets with wet hands, keep them away from eyes, store them out of reach of children, and flush the machine thoroughly before pulling a drink.

What actually goes wrong

  • Follow with a long water flush and discard the first shot.
  • A tablet left in the blind basket overnight is not more effective — it just corrodes.
  • If the machine is used daily with milk drinks, keep the weekly interval.

What it has to match up with

  • Backflush disc
  • Group head brush
  • A machine rated for backflushing
