Posted Thu Jul 12, 2012, 6:16am Subject: new gaggia classic and portafilter trouble
I bought a new gaggia classic and had trouble with the perfect crema baskets, so I bought a classic basket . it fits the porta filter if I click it in but I am having trouble then attaching the portafilter - it seems to need a lot of force. I tried the perfect crema basket too and it seems to be the same. The porta filter fits fine without the baskets! Does anyone know if I need to buy a different portafilter?

You shouldn't have trouble if that's the OEM Portafilter that comes with the Gaggia. Perhaps, insert the PF body MINUS the basket into the group and lock it in, loosen and repeat maybe 10-15 times. The "ears" of the PF may just need to be worn down a we bit.
Next, do the same with your classic basket inserted into the PF.
Truly, though, this should really not be an issue. Could the portafilter gasket not be fully seated? If not, the above steps should fix that.

Agreed basically w/ the above.
I wouldn't expect a problem with the ears on the basket needing to be worn down but it's not a bad idea, maybe check for burrs around them.
The PF should fit fine on its own but adding a basket raises the overall thickness there and makes things harder to put in place. It's to be expected but only up to a point.
When I've dealt with repairing used machines I have to be sure to get the right gasket thickness or that kind of problem can develop but I wouldn't expect any issues with a new machine. Strange.
Some force is to be expected, it won't be easy to put in place, it needs to seal back ~165 psi or so of very hot water. But it shouldn't be *too* hard either. Also keep in mind that you don't have to go much further around than just having the handle pointing towards you. Somewhere between the 5 and 6 o'clock positions, closer to 6.

The tamped dry puck should not reach the screen or screen screw. When expanded after a double pull, your wet puck will then probably just touch the center screw and you will tell that if you see a slight impression in the center of the puck.
