Hi I'm John I will help you with the problem.
can you hear a hum before it kicks the breaker off ?
It could be a timer problem you can open that timer by sliding the metal shield to look at the contacts if the contacts are burnt replace the timer.
If it wont even fill i would think the timer is the problem but I cant be sure of that .
You should call in a service tech on this one .
Glad thats fixed as far as the leak the tub seal kit has to be replaced, heres the part required and some instructions on how to replace the seals.
I would get rid of that washer it wasn't very good to start off with and buy a sears Kenmore or a whirlpool their easy to repair not like yours.
And you can do the repairs yourself .
