You're welcome -- Hi again
Yep it needs a repotting, looks like you've got some nice long healthy roots left. Take out / cut off any brown
mushy roots. And by the looks of it, it'll be a good number of them. Don't worry about this, with nice clean media you're phal should be able to rebound nicely.
You can rinse out & scrub down and use the same pot if you think the roots will fit. Allow some extra room for the new roots to emerge.
When I repot I normally leave my media dry out for a couple of days to allow the cuts, nics & dings heal up. Then water as usual and use fertiliser a week later.
Good luck with the repot, you're phal should be fine
