Shower toilet spontaneously spits water around

Power outage on only one phase? I'm not an electrician, but I don't think that's "that simple" ... I am convinced that this was not the cause (without being able to explain it in detail)

I simply don’t know the toilet in detail. However, I can well imagine that the installed electronics do not always work properly when there is or was a failure. I can report an example with an induction stove (touch). There was also a phase failure and the resident wanted to cook something. The display with clock etc. worked completely normally, but the burners did not. After everything was powered again, a burner switched on by itself when a pot was placed on it. Unfortunately, I don’t know what happened after that.
A failure on one phase is not unrealistic at all. You just don’t notice it because usually others are faster and contact the supplier. The rest happens in the background. You don’t even notice the repair of the affected cable. Nowadays, work is usually done under voltage instead of switching off.
What makes me suspicious is just the LED light, which is supposed to always be on.

I'm only suspicious of the LED light, which is supposed to stay on all the time.

yes!
Although this is a different aspect, I would also like it if it could be turned off.
It is practical to find your way in the bathroom at night, but I am a fan of darkness (where it belongs) and the night, for my taste, "belongs" to darkness.

One possible reason for the "always on" version is that the people from AXENT have integrated all important functions (beam direction, temperature, pressure – and I don’t know what else) into one button.
After setting it once, I practically don’t adjust anything except "off" and "on".

If I were a designer of a shower toilet, I would - similar to the light in the fridge - build in a function that water can only flow when weight is applied to the toilet seat.

We are also considering whether a shower toilet fits into the budget! We would then want to choose a Geberit. By the way, it includes the weight control!

Weight control? Please don't tell me now that it weighs the "pile" daily and uses Bluetooth to create an online leaderboard with other toilet veterans?

The next generation will then definitely have an analysis function. Together with the Smart Watch and the Smart Refrigerator, online food orders will then be automatically adjusted in case of poor utilization and bad body values.

Somehow, such thoughts make me afraid of the future.

Is this going to be a new "Haufen" thread? Cool
