2nd shot trouble [Profitec Go]
Since two weeks I have a problem with my Profitec GO & DF64:
I let the machine fully heat up. First shot runs perfectly fine! 18g in, 36 out in 25 seconds with around 9 bar of pressure.
EVERY shot I pull after the first one runs WAY too fast. 38g in 18 seconds and pressure won’t build up more than 8bar.
I prep both shots exactly the same way, dry the portafilter & puck screen and temperature on PID is exactly the same as during the first shot.
With the blind basket the machine has no struggle to build up to 9.5bars every time.
The same pattern occurs even if I try 18.5g in on the second pull.
Any idea what the Problem could be?
