whats wrong with my hotpoint aquarius CTD00 condensor dryer?

its about 3 yrs old
it was working ok, then i went to switch it on and nothing happened ? checked fuses, all fine, checked socket all fine, cleaned condensor out, wasnt that dirty, emptied condensor, which was less than half full.
i have no clues as to whats wrong, please someone help, i have two children and an mountain of washing to dry.
