My laundry room has a putrid odor

We moved into a new house, it took about a 2 weeks to connect the washer and dryer. We are using a washer and dryer from the previous owners and they went without use for at least 1 year. Once we connected the washer/dryer and started using them, the laundry room has a putrid smell. It's horrible and some of the living spaces close to the laundry smell as well. It's LG front load washer, I ran the tub clean cycle 3x (1 empty, 1 with vinegar and another with bleach) and it didn't do much for the smell. I then tried to clean the rubber seal as best as I could. I also cleaned the filter and emptied out the water. It still smells. At this point I'm not sure where the odor is coming from, but it makes me want to puke. Our clothes do not smell and I don't use any scented products on them.
