The Gaggia Classic has a 3-way valve and backflushing not a problem...

Any machine that can be backflushed should be backflushed regularly. Water
backflush after each session (even if it's a one shot session), detergent
(Cafiza or Purocaff etc.) backflush at least monthly or weekly depending on
shot frequency and/or after any entertaining/lengthy shot session.

Caution needs to be used detergent backflushing E-61 lever style machines.
It removes lubrication from cams which can cause pre-mature wear if not

Ultimately the quest for Koffee Nirvana is a solitary path. To know I must
first not know. And in knowing know I know not. Each Personal enlightenment
found exploring the many divergent foot steps of Those who have gone before.
