Hi, I took off my Intellichlor IC40 for cleaning. On the side where the water flows into the SWG there is a plastic grid at the mouth of the opening like the one in the picture below. My plastic grid fell out of the SWG and it looks melted or warped on one side. It's not longer round and it doesn't snap back in with a tight fit. I was able to carefully seat the plastic grid back into the SWG. It's a loose fit but the SWG is reinstalled and looks to be working. What is the purpose of this part and why/how would it fall off? Should I be concerned and do I need a new SWG?
