i think the water filter may be messed up in general

I would call the store wherever you got it from. Maybe it has a warranty

My mom's fridge is having the same problem. I can't figure it out, but I'm no repairman. I want to just buy a new filter,does anyone know where I can get these cheaper? They're expensive at the store too. I really think a new filter will solve the problem, not positive though. I think it's the first thing to try, but man... she needs this one, a Ge mwf.

What's the model number?
