» (e2)
until the indicator lights come on. Release
the controls.
All the indicator lights will flash then go out.

of the descaling operation which has just
been performed. During future use of the
machine, the «
» indicator light (e1) will
remain off until it is again time to descale the
machine.

In the case of serious scaling, soak the the
grille of the percolation head for 5 minutes in
1/3 of the mixture obtained during the first
run-through. Then rinse and dry it.
If necessary, this operation can also be
performed with the steam nozzle :
• To do this, dismantle the nozzle as instructed
in the paragraph «Maintenance» and soak
the scaled parts for 5 minutes in 1/3 of the
mixture obtained during the first run-
through. Rinse the various parts thoroughly
