I used to ask electrical engineers who design building utilities if they ever touched a live wire with voltage running. If not, "how do you know it is really dangerous? How do you know it will electrocute you?" They don't. EVER. Want to talk to me again if they don't have to. #ConventionalIgnorance For reference, I touched 10k volts with microcurrents. It hurts! I touched 240 volts wire and felt the vibrations run up…
Jewish law requires some new utensils to be ritually immersed in water before use[1]. There are differences of opinion around electrical appliances, but I have successfully dunked toasters, cheese toasters, and many other small appliances, let them dry for a few days, and never had any issues. In fact, had OP found this[2] article, they would have seen that > Practice has demonstrated that immersion generally does no…
Sorry for digressing, but what's a cheese toaster? That sounds exceedingly interesting.

> These commenters are speaking authoritatively on subjects about which they are completely ignorant, but they are strident in doing so because they are repeating what everybody knows. They are intellectually secure in the center of a vast mob; their wisdom was received, not crafted. This is an important takeaway for me, maybe even more than “electirc devices are washable”. World is filled with conventional wisdom th…
It's not the water that's the issue generally - it's the minerals in the water. The article author got lucky this time - when electronics die from water contact, it's usually the minerals bridging connections and creating shorts. Letting the device dry does not remove those shorts. Some places have such hard water (lots of minerals) that evaporated water leaves calcium, limestone and other deposits on the surface of…
They would probably represent nothing more than minor stray resistance/capacitance.
Assuming it was conductive enough, a scales bridge between higher voltage parts would just represent a path of material a few microns thick that would vaporize as soon as the toaster would be plugged in.
For other electronic devices, any component with a hole, like a microphone, barometric, humidity sensor, or mechanical (HDD), is more likely to suffer a more permanent fate. If water gets inside a relay housing, chemicals from the washing liquid may damage or gunk the contacts and reduce their life. LCD screens, glued parts and thin plastics don't fare well in dishwashers either...

There's a reason you don't see this type of water heater in most of the world.
yes, and that reason is mostly the kind of people who were asking the original poster how he made it to adulthood
I can count on zero hands the number of times my shower has given me a jolt, even a minor one.
We mostly see these types of devices in relatively poor countries without the means to install more modern and safer alternatives, such as whole house water heaters.

I still wonder how electrocution is not a big issue. My local electricity codes say absolutely no electricity within zone 0. I get a bit nervous about hooking up IP 65 rated lights to a IP X4 rated switchbox a meter away from the shower head
Electric showers are very common in the UK - although the heater is in a wall-mounted unit, with the head on a hose, rather than the heater being in the head itself. The heating element has three layers - innermost, a wire that gets hot. Around that, a ceramic insulator. And outermost, a metal cover to protect the ceramic insulator. Then the heating element is mounted in a small water tank. And that, along with some…

Right, I'm sure it has nothing to do with the plethora of "shocking" tales regarding these water heaters. I can count on zero hands the number of times my shower has given me a jolt, even a minor one. We mostly see these types of devices in relatively poor countries without the means to install more modern and safer alternatives, such as whole house water heaters.
i mean it's the same reason most people in the usa don't have a bidet in their house; it's not because they're too poor to afford one. technology adoption is path-dependent and mostly random, and fear makes people conservative. yes, there are a few people who are familiar with the actual risks and rewards of the different technologies, but they're vastly outnumbered by the pre-galilean minds who are entirely guided by conventional wisdom
most people in the usa can count on zero hands the number of times they've sprayed water on the bathroom ceiling from their bidet, too
I stopped watching the show Ozark because of the episode where the saboteur takes an AC line and drops it into the water by a dock in order to electrocute someone. I'm no expert in electricity, but I know that your body has to become a part of the circuit. Similarly, the pivotal moment at the end of The Astronaut's Wife (1999) had me groaning.

I have one of those at home in the UK, in fact I only recently changed the older unit that was getting long in the tooth. The house is old and an electric shower the only way to have a proper shower. I also have a shower extension, a rubber tube with two inputs you connect to the hot and cold taps in the bath tub and which outputs cold water if you hold it lower than the taps and hot water if you keep it above the ta…
