It’s not considered OK to double post here like it is on some sites. It puts more of a load on staff and users trying to help you.
Unless this is fixed and it’s a new post? It seems to be the same issue, but the wording is a bit odd for me.
Maybe @JohnJohn can check it out and, if need be, move it your other thread here or vice versa.
On a Ruida, usually, when it’s illuminated it means active. So led 9 is Water protection input and it’s status is displayed on the leds. I think if you invert one of these, that hardware isn’t smart enough to realize that it’s been inverted by the user.
If you turn off the coolant pump or it fails, the led will extinguish. Of course, this makes the assumption that it’s wired up to detect this circulation failure.
These two tables on the Ruida identify which leds mean what.
Led 15 indicates you have 5V generated from the Ruida. Led 14 is the RUN led, it flashes after it boots, indicating it’s running.
Did you look at the motor drivers to see if the error led is lit?
When you put the wire back, how do you know where it goes? Usually these types of electronics are very dependable, but depending on yourself to hit the e-button, is dreaming. Most of the time a bad connection burns something out long before a human can detect it.
