Specifically, I have the following model units:
Maytag Washer WTW8040DW
Maytag Gas Dryer WGD8000DW4
The units come with open seams, and I'd like to know if it's safe to seal these? Surprisingly, Google search didn't net any relevant results for me, and there's no mention in the manuals either. I'd be using either 100% silicone, alex caulk, or some other sealant depending on safety implications.

EDIT2: The objective I'm trying to achieve is sound- & vibration-dampening. Please note that I have already implemented most standard "fixes" (see comments below), but short of purchasing actual soundproofing out-of-pocket, I believe this would achieve some functional effect. I only want to make certain that there is no safety concerns with proceeding.
