GE Dishwasher issue with hard water - apartment complex maintenance not helping

Hi, so my apartment complex installed the new dishwasher when I moved in 1.5 months ago and because I have hard water apparently even with the finish hard water rinse aid it doesn’t make a difference with it or without it and they didn’t seem to care … so we don’t have plumbers or electricians there’s just general maintenance guys They said they’re gonna get a filter for me .

now as the detergent I use the cascade powder & I’ve used the pods. I haven’t used the liquid yet, but I don’t think it’s gonna make a difference … I put it on the heavy cycle and always put everything to the max, hottest setting, etc. It’s a GE

they’ve known this issue has been well over a month And yes, they agreed to put in a filter, but I mean is this normal to happen even with the hard water rinse aid? I mean, look at how some of these dishes come out. I have too much pain to be standing and washing dishes. One of my questions is You know I rinse thoroughly through things before I use them and if it’s not acceptable, I don’t use it, and wash it again but is this leaving residue that I would be in ingesting and would it be harmful?

I’m pretty sure I’ve lived with hard water before and I never had an issue like this with a dishwasher so I’m concerned. I’m not sure how much a filter cost but too bad rent ain’t cheap . if other people aren’t having this issue why am I? Lots of plumbing issues in my unit apparently. It ain’t just this
