Hi Matty
can we have a vid of final rinse, emptying out, distributing and going in to spin please? (so I can gauge the noise?)
Don't let the machine rock on a wonky floor like that, it is washing machine torture. If you can, adjust the feet to sit level. Otherwise use a wedge of wood to hold it evenly and stop rocking. Absolute level isn't important, but absolutely no rocking is important. These machines can give themselves inside-out dents in the cabinet when the drum bangs around too much.
Leaks - I can see at least two, possibly three leaks.
1. Leaking between backing plate (dull grey metal whole back of drum) and the stainless steel drum (shiny steel sheetmetal.) Covered in my last post in your other thread.
2. Leaking rubber seal where air dome attaches to backing plate. Should be easily repairable by removing the rubber seal, clean it up carefully and thoroughly with a stainless steel scourer (eg: curly girl scourer), then re-glue it to the backing plate. If the rubber seal is stuffed I can send you a good used one. Air dome is below big pulley, leak showing at 5:07 in your first video.
3. I can see a line of water dribbling down from the bearing area of the backing plate. This indicates a failed main drum seal (in between the drum spider and the bearings). There is a weep hole or 2 built in to the backing plate, under the bearing area in the middle. It is designed to drain away any water that sneaks past the main seal and dump it at the back of the machine, to stop it getting in to the bearings. That's the dribble I can see in your video. This seal failure is why the bearings are stuffed - water has got into the bearings. This leak will disappear when you replace the bearings and seal.
4, Washing machine with top open, outside, running, leaking, water around floor and leaking inside machine - please tell me you have it connected to a safety switch??? (Earth Leakage detector) - without one you are at risk of a fatal electric shock in that situation.
Sorry to be a nag but I'd hate you to get zapped trying to fix a machine following my directions...
