Cuber freezing at the front plate of it and at the bottom of the cuber

Hi ! :) (Disclaimer! I didn’t really have a good picture but picture #3 kinda shows what’s going on) I just started got hired into this job and I just finished school for hvac and I was wondering what could be causing this cyber to do this ? I checked the water inlet valve it had some grime in it so I cleaned it out but when I did the mesh that’s inside just completely fell apart so I just got a new one and put it in , I also replaced the water filter which was filthy , and I also cleaned out the black bottom rubber part of the float switch but now I don’t really know might be causing it submitted by /u/Candid-Jellyfish-931 [link] [comments]
