I have a three head Faema Ariete from the 1970's. I am trying to figure out how to adjust the water level in the boiler. It fills to the Max limit on the glass and I am thinking about 1/2 way up is better. Anyway I am a Novice owner of this machine and would appreciate any help I can get. The only electronics on the machine are a pressure switch to turn on the pump and fill the boiler.. thanks

You're going to have to figure out what controls the water level- either by a probe in the tank or switch ( magnetic, etc.) If its a probe- the adjustment is easy. If its filling to the max it could be just a dirty or scaled up.
