Improperly reinstalled the pump filter, now I can’t remove it

I didn’t reinstall the pump filter on my washing machine properly (forgot to align the notch on the filter with the tab in the tube that the god awful manual instructions made zero mention of), and now the child lock is preventing me from fixing this. Thought I just wasn’t using enough power, but the cap physically won’t push down.

Hoping that there’s a way to fix this without calling a service provider, I’d prefer not do that if I can avoid it
