Just bought my first MP10

[AirIck]

Hello, I recently purchased an MP10 this week. I had it running all week no problems (i put it on constant at night at 5%) and it has only been on 20% Lagoon during the day. This morning it popped off my glass and was hot. I checked the app and it had the warning "temperature" and it was super hot to touch. Has anyone else had this issue? Do I have a defective pump? I have not heard of others having to turn their pump off at night so I'm confused why mine is doing this, escpecially only running it at 20% and 5% at night
