It does not seem "typical", but the inability to rotate the PF to 6 o'clock
is not unheard of. there are several possible causes and each suggests a
different fix. Your comment that it occurs with and without a basket is
particularly surprising. A past cause has been that the rubber gasket in the
group head is "not quite the right thickness". When this is the case,
putting the PF in without a basket allows the handle to rotate closer to,
and sometimes past, the 6 o'clock point. (Whether the PF has coffee in it
is pretty much irrelevant if you are only putting 15 to 16 grams into the
double basket ... you do know which one is the double and which is the
single, right?)
First question: exactly which machine model are we discussing, when did you
purchase it and from whom.
2. How far does the PF turn with the basket in and how far with no basket in
(and the same amount of pressure on the handle for both). ... Did it ever
turn correctly, or was it this way from the time that you opened the box?
3. Would you describe the feel when it stops ... is it a slow increase in
pressure until you just can't turn it any further with reasonable effort, or
is it an abrupt halt?
4. Do you have shop nearby that you could persuade to insert your PF in
their machine and tell you if anything feels odd. (PF and grouphead
specifications are a little different from manufacturer to manufacturer) so
it might not turn exactly to the same position as it should in an Expobar
machine; see if you can get the name and model of the machine you test the
PF in.)
The problem probably is with the gasket. They are available in sizes that
vary by a half a mm and between the loose manufacturing tolerances and the
possible "put the latest parts inventory shipment into the wrong bucket"
problem, you may just need to just change the gasket which your supplier
will probably send you for free. (He is a victim of the factory too, so
don't get too upset with him.)
There is a theoretical possibility that there is a flaw in the PF or the
positioning or shape of the grouphead lugs, which means either a new PF or,
if it is the group head, an exchange of the machine.

Subject: Portafilter not turning
Hi, i have issues to get the portafilter to turn on the machine. I can get
i to 7 o'clock barely and impossible to get it to 6o'clock. Tried with and
without basket and with and without coffee. The machine is brand new,
anyone else had this issue is it typical with new machines.?
Thanks
A.
