Warsher second spin doesn't drain

So I have a Maytag top load warsher that is phenomenal. Got it for free with the dryer and it's a gods send.

My question is when the second spin cycle happens it's doesn drain all the way. It leaves like an inch or 2 of water in the bottom.

It drains perfectly fine the first time. But not the second. I'm fairly handy and could probably fix whatever it is but appliance repair isn't my forte.

I do run a cleaner tablet ever 60 days. And I've run it empty and it still doesn't drain.

Any info would be greatly appreciated

Thank you in advance
