I have a Octopus DNWB-200 and the otp3000 pump is making a chattering/rattle noise. Trying to figure out the best way to fix this. Already trying cleaning everything and it still makes noise.
Do I need a whole new pump or will a new Impeller fix this?
If it's still making the noise even after a good cleaning then the impeller assembly is most likely needing to be replaced. How old is this impeller in there now?
