I have a whirlpool gold washer. It works fine on all the cycles except the final spin. Once in awhile it will spin out completely. Most the time it won't. If I open it up and remove a bunch of clothes, rearrange them and or help get the drum spin it will spin out. Sometimes if I hold the agitator it'll start spinning. Any ideas of what it is? I have a few of what it could be but maybe someone knows the exact problem. I'd like to be able to order the parts so we're not completely out of a washer for a week

I just replaced the coupler last year FYI
