@henene4 - People talking about stuff they don't know
I wouldn't be so quick to discount Rapunzel's statements - after all, they technically haven't been proven true OR false at this point in time, As far as I know. Theoretically, vibrating water with 2.4GHz micro-waves shouldn't make a difference, but it could do so, enough that only people with "the bad genes" are affected.
You should also be careful about what you say regarding hackers. Remember they are people who either do things to annoy people because they don't have a life, or because getting their life-savings will make them rich.
Wi-Fi is actually VERY in-secure, depending on the method used to secure it (I'm looking at you WEP!).
Online Banking is VERY insecure - since people who hack into the servers can act as "man in the middle" seeing what you see, before you see it, and meddling with your data.
They can also hack your "secure" connection, with credentials akin to the security certificate.
And of course, if you have a virus on your computer, then any "secure connections" are just a load of crap, since those programs watch what you are doing, then phone home via a different connection.
There a probably many other ways of hacking into technology. Just because you don't think they have business on an automatic washer, doesn't mean they won't come. Its like saying the Titanic was "unsinkable."
And remember, if you need a secure connection, then you need code that supports that. That code is never 100% perfect, and thus requires updates, or else risk being hacked. The base code of the washer might be inherently insecure or buggy, too. More places to "get in."
