Feeder tension should be in the middle position, don't forget to put it back.
Maybe you can try another filament as a test, to see whether or not it has anything to do with the PVA.
Any kinks/sharp bends in the bowden tube that causes extra friction?
How does your pva feel? Does it feel sticky?
Do you store it closed? Pva gets slippery when absorbing moisture.
