Wow, that sucks. Sorry about your mishap.
I got my GE washer / dryer today. The guys hauled my old stuff away (good riddance) and loaded the new stuff into my utility room. I installed it myself as I wanted to simply to avoid what you went through.
In hind sight, the washer was so heavy, I should have let them install that lol. They were pretty good through and through and had all the right tools for the job. And yeah, that steam hose install - what a disaster.
Edit: BTW, if you have steel braided hoses, you should replace the rubber ones. Effort could be worthwhile for insurance purposes, should anything happen (heaven forbid.)
