We just moved and our washing machine is really not liking the floor upstairs (we are in a flat). It's floor boards and when it spins the whole room shakes.
I've adjusted the feet as well as I can and today I put a thick plywood piece under it, screwed that to the floor, and then attached the machine to that using metal feet and bolts which the manufacturer sent me.
It's still wobbling. It's a bit better but it makes me nervous that it'll damage pipes underneath (gas, water both run under it) and that it'll be pissing off our downstairs neighbour.
Before bolting it down I used some rubber feet but they just made it jump around even more.
Does anyone have the answer? Thinking of building some sort of outhouse to put it in but that would mean going out to the garden to do the washing, which isn't fun in winter.
All thoughts appreciated
