Washer won't wash, spin, drain water
 

Hi My whirlpool washer Model: LA5460XTW1 stopped working after a heavy load. It can fill the water, but won't wash, spin. It eventually drained water after place the dial on the correct position. The motor has normal running sound but no moving part inside the washer tub. Could you please tell me if it is worth to repair? What parts should I try?
