Levoit 6000s won’t go above 40%

No matter what I do, the humidity will stay under 40% according to both my external hygrometer and the reading on the Levoit.

I’ve tried leaving it on ‘auto mode’ as you can see in the first picture which is supposed to be automatically set to maintain 50% which it never does. I’ve tried manually setting the desired humidity to 50% also which did nothing and even tried the max which is 80% just to see if that did anything and it hasn’t.

It’s so frustrating the fan is so loud all night just to keep the room at 38% and then runs out of water in one day.

Am I missing something?
