I think the pump is ok but its good to know its possible to get a replacement pump,i took of the plug and measured the power with the vacuum hose of and i have 0 volts.
From reading other threads i understand that this pump should be running non stop with the hose disconnected, i wil start with replacing the fuse(they all looks ok ) and see if i have power in , if there is power i am thinking a bad cable somewhere between the fuse box and the pump.
I dont have the manual ,i have ordered one and its on its way, can someone tell me which one of the fuses that goes for the vacuum pump?
This link is very good it help me understand how it all work
thanks
