i had a similar novo something and found that unscrewing the black plastic section of the portafilter helped (somewhow). it basically created a naked portafilter.
do u have a grinder?
do you have a tamper? if i recall, the basket is around 53mm diameter so difficult to find a tamper that fits well.
the baskets are also a bit funny where they have little hols and also thin lines...not sure why...i would try to find baskets that only have holes and see if that helps. i discovered that i was getting squirters from the lines.
