      Only if your particular Ascaso Dream espresso machine has a three way solenoid valve inside the top cover.  Older units did not have the three way solenoid valve and con not be backflushed.

      I336 is the back flush insert for the 57mm versions. R037 blind filter insert for the 58mm Dream PID espresso machines.
