Cat water fountain life expectancy

Hello! I bought this water fountain from Lazada last October and I can say super helpful nya in getting my cats to drink water. However, after 5 months of use it recently stopped and I can't figure out why. Wala naman din bara akong nakikita. I just wanted to check--is this about the life expectancy for water fountain pumps or did I overuse it? I just kept it plugged in 24/7 but wala naman ding warning na dapat tinatanggal sa saksakan after a few hours or anything. Any tips to help get this pump back running would be great, and better water fountain recommendations are welcome. Thank you!
