Recently did a cleaning of the 3-way valve in my Gaggia Baby Class and afterwards I'm having a problem where, when I press the brew switch and then turn on the steam wand to prime the machine, water continues to flow out of both the group head and the steam wand.
I hear the "click" of the solenoid kicking in and the hum of the machine sounds normal, but somehow I'm still getting water out of both.
I checked the 3-way valve again and it's in the closed position (if I blow through the top of it air only comes out of one of the holes on the bottom). I've also checked my wiring from putting it back together and that all looks fine too.

I am not sure that I totally understand. On my Classic when I have a partially filled boiler and open the wand and turn on the pump, I do not get water out of the group until the boiler fills, then out of both. The pump will flow 600 cc/min with no back pressure and apparently the wand cannot flow this and some comes out of the group once the boiler is full.
Water out of both when the boiler is partially empty?
