Those were for Japanese wired Washlets, that were never supposed to be installed with US wiring.
Japan has very different electrical, and the models imported for the US, are UL approved. There has been no problem with Washlets for the US market.
Sometimes people buy cameras and Washlets overseas, bring them home and then jerry rig them to work here.
I get a few calls from people asking how to convert the power cord, or how to hook up the metric connection to a MIP connection.
I just tell them, next time, buy it here.
I've been selling Washlets for over ten years in the US, and have never heard of a US recall for products that have been UL listed like the ones that have been testing and approved for the US market.
The reason so many people "want" to bring them back, is that once you've tried them, you can't go back.
The US is way behind the rest of the world, in how they treat their behind.
The US concept of clean is like bringing your kids in from playing in the dirt and rubbing them with paper towels to get the dirt off.
The rest of the world uses water to clean with.
And it's not required that you use warm water to wash with, either cold or warm will wash better then dry paper.
You may want to try this on your dishes too.
Wash them with water, they come out much cleaner then using paper towels.
Heck, you can even use water to wash cloths. I know people in the US like to rub their pants with paper towels to get them clean, but people in other countries use water.
A washlet is the best thing you will ever put in the bathroom.
It feels nice to have a warm seat to sit on in the middle of the night.
And the warm water wash does a lot better job of cleaning.
It even cleans the bowl better.
Some models even have filters for air cleaning.
I think my Toyota Highlander has an air filter too. Even the old 1996 Ford Taurus had an air filter for cabin air.
I don't think TOTO is in trouble, they are the largest plumbing manufacturer in the world, and INAX, other washlet maker that has UL listed products is the second largest plumbing manufacturer in the world.
In Muslim countries in the Middle East, where they wash with water, most homes have stand alone bidets.
They even have them in Guatemala.
