Matsui MF160 Not releasing powder?

I've just put on my Matsui MF160 dishwasher for the 3rd time today and its not working.

The powder is still in the white thing on the door and the dishes are just wet and not cleaned. I'm no expert but I think that the water is not heating up (as when I open the door there is no steam and the plates are still wet).

Anyone have any ideas?? I've only had the damn thing since early May.

ALSO.. It used to beep 2/3 times when finished its cycle, it now beeps around 10/15...
