Washer won't agitate/spin

Need some help! My washer won’t spin nor agitate. I replaced the motor coupler with no difference. The top half of agitator works fine, dogs are fine, however bottom half won’t budge at all. I don’t know what to do or where to start! Any help is appreciated!

Hello,

Does the motor work?

What is the complete model number of the washer?

Gene.
