AITA for not cleaning out the washing machine

Am I the asshole of not cleaning out the washing machine let me(21 female) start this by saying I live in a shared house with 3 other people for the sake of this story I will call my roommate Andy (34 male) . So I moved into this shared accommodation 3 months ago when I first got here it was dirty and Andys things was taking up most of the kitchen sides I even found a joint on the side by the sink anyways fast forward a month and everything's fine I have just used the washing machine and I am hanging up my clothes when there's a knock on my door it's Andy telling me that I need to wash out the washing machine as I have a dog and his hair gets everywhere which I did then I continued to hanging my clothes you would think that's the end but it's not. I had just worked 5 days in a row and I just wanted to sleep before I decided to put a wash on and accidentally fell asleep again after I took my clothes out I cleaned the washing machine remembering what happened last time a while later I got a knock on my door saying that it was dirty I said that I cleaned it wiped it done and put it on the clean cycle but he still said I needed to clean it again so I did. A few weeks later I had hurt my ankle at work so I decided to go to A&E to make sure everything is okay while I'm out my other roommate we will name her Emma texted me saying that Andy has sent him a video of dog hair outside my door in the hallway I said I will clean it when I get in it everything was fine with my ankle but I needed to rest/ evaluate it so I got home hooved and as I was hooving up the dog hair he came down and just stood there for like a minute straight watching me hoover I had told him that I had been in A&E but he just walked away which was fair enough fast forward to current time I had work another 5 days in a row and just wanted to sleep as it had been a long week he came knocking on my door once again asking if the dirt marks on the floor were made by my dog I said no as they looked more like boot marks and they had already been there when I had taken my dog out he then asked the other guy who lived with us who said it was me which Andy then came back to me abit more annoyed which I them repeated that I wasn't my dog because it's wasn't the first thing they tried to pin on my dog like (weird smells etc even though I bathe my dog regularly) he then went back to the guy and they started shouting I asked them if they could stop as I came from a bad household and I'm autistic and my mental health hasn't been good and can't do shouting which I was very open with them when I moved in i also told them that it also scares my dog as he also wasn't treated right he screamed that he didn't care and caused me to make a meltdown I don't know what to do because anytime any type of dirt is on the floor he comes to me asking me if it was me i don't know what to do so am I the asshole
