So, we have the Circupool SI45. My question is mainly about design. I've seen other swgs, the housings are clear and it's easy to see if they are operating. This housing is solid white and I can't tell if it's working or not. How are we supposed to evaluate it's operation? We took it off to look inside at the metal plates and we can't even seen the metal plates for all the plastic brackets. And if we decided the metal plates needed to be cleaned, how do they expect us to clean them.?
