New Philips Barista Brew

We bought this new batista brew 2 weeks ago.  No matter what we try, we don't get enough pressure. We tried:

-smaller grind size; -different fresh coffee from local shop; -having more coffee or less in the cup; -making espresso without the portafilter for cleaning -having the steam wand working 15-20 seconds before using the machine to remove air bubbles.

Would gladly appreciate if you have other ideas before we return the machine.

**we bought it for the dual coffee recipient but don't bother to buy, it doesn't work. It takes 2 full cup before grinding the other coffee.

Thanks
