No Water from Triton Zante 3?

Hi All

I will give you some background:

2 months ago I bought and fitted a Triton Madrid II Shower.
Everything was fine, then I had to fit new coving which meant moving the pullcord, I accidentally wired it up wrong and it made a loud bang and tripped the fuse at the board. After correctly wiring up the switch everything was fine, then a few days later the shower wouldn't switch on, no water was coming out.

I assumed I had damaged the shower so I purchased a Triton Zante 3, this time I took extra care to make sure I didnt make any mistakes, but no water is coming out, I havent been able to get past the commissioning stage in the instruction manual, i.e. the point where you just run cold water through the tank before heating it up.

Can someone please help, I am starting to smell and my girlfriend is very unhappy :(
