Crap your float is corroded , must have some crappy water . Check the belt on the other side where the motor is. They break , easily replaced . Buy a spare when you get one .
@AnthroKenji spray down the build up with lime away . Get a hose up there to wash it out . Take all the sides off and make sure your water pump works and that the float shut off works . Once it’s clean and water is in it put a cup of tide ( powder) in it , put the sides back on and run it . It will clean your filters and it smells good !
