how can i fix my servis 1100 washing machine?

my servis 1100 washing machine,lights power light up,but no programmes work,it wnt fill,makes no noise at all. i was brushing beside washer and slightly khocked washer side with brush,not at all hard,it tripped all my dwnstairs sockets out,when i turned them all bk on washer lights power button but nothig else,i noticed the right side of washer appox 6 inches off floor inside has a square box with wires ffeding into it,these wires start at front controls and feed around washer to the box. this is where it was banged but from outside of washer,when slightly pushed the washer side touches the box,i think this is what caused it to blow electrics,although it shouldnt be so easy to do,what can i do to repair it and will it cost me alot to repair,plse help,thanx
