Your espresso machine shows a CLEAN ME or cleaning-cycle prompt.
Espresso coffee-oil care
Espresso machine backflushing
Backflushing cleans coffee oils and residue from the brew path behind the group head on compatible espresso machines. It normally uses a blind basket or cleaning disc and a machine cleaning programme.

When it comes up
When should you think about backflushing?
The manufacturer supplies or specifies a cleaning disc, blind basket or backflush routine.
The machine manual explicitly calls for a cleaning tablet in the group-head cleaning cycle.
The safe general approach
The machine procedure still wins.
Use this as orientation. The exact controls, product placement and programme sequence should come from your model-specific guide.
Confirm that your machine supports backflushing before starting.
Fit the cleaning disc or blind basket exactly as the manufacturer instructs.
Place the cleaning tablet in the specified location — not in the water tank.
Run the complete cleaning programme and finish any rinse steps.
Do not backflush a machine simply because it has an espresso group head. Some designs are not intended to be backflushed.

Troubleshoot the symptom, not the guess.
If a warning will not clear or a programme behaves differently from expected, start with the symptom before repeating the maintenance job.
