Marks on washing

[Tommymummyft]

Has anyone had these marks on light clothes when they come out of the washing machine? It’s happening all the time and I can’t get rid of them.
We have recently had a new seal in the washing machine so that’s clean, I keep the detergent drawer clean too.

I was coming on to ask the same question! It’s so frustrating. I also have the issue that light or white washing is coming out almost grey.

It is so annoying! If I find an answer I’ll update 😑
