If the outlet tested good for polarity and ground, then I'd remove and reset the washlet on the base plate.

I'd unplug the unit, remove the washlet from the base plate that is mounted to the toilet. You need to be careful doing this as the water hose is still connected.

To remove the washlet from the base plate, when you are facing the toilet, there is a button on the right side of the washlet, towards the rear, just below the deodorizing grate. Press that button while gently pulling the washlet towards you. When clear, make sure there is no debris on the base plate or on the underside of the washlet. Then reset the washlet on the base plate.

It should click into place.

Plug it in and try again.

There should be a troubleshooting section in the manual. Refer to that if you haven't already.

If no luck there, then call Toto tech support.

Your husband? Hey, I love our washlets. We have a Toto and a BioBidet. Embrace the washlet, says I.

Thank you MongoCT. I will give this a try. It was installed by the plumber so it's possible he didn't read the manual. I have never used one of these before and neither has my husband.. I think we'll embrace it...after the laughter dies down!

@Gloria Reese How did you fix it? I had power outage at home and since then C200 power LED light is not coming on. Checked all circuit breakers. Everything else is working fine.

Mine is having the same issues. Power went out now the power on toilet isn't

I had the same problem. After a Thunderstorm, the Washlet had no power lights on. But all other circuits in the house were fine. Turns out that the ground fault outlet had tripped in the bathroom behind the bathroom the washlet was in. Obviously those two outlets were connected directly thru the wall.

Initially I was worried that the washelt had fried, or a fuse had blown.
