I can speak to the toilet. On my third one. First two lasted less than a year each.
Fixing yours would need more info. Does the macerator try to run, lights work on the panel, etc??
Nothing goes down mine any more if you did not eat it, including all toilet paper. I know this sounds rough, but marine toilets are the same way. The macerator just can’t take too much paper at one time, etc. My grandkids only use the half bath toilet.
