Currently servicing a TW, and the powerball detection sensor in the trough, is not doing a good job detecting the sensor. I determined that I needed to re-flow the sensor board, and that helped. But now I have a question about the "alignment" of the sensor itself.
Currently its working, but the metal ball needs to physically touch the Hall sensor to give the proper detection. Seems to me that this is not ideal because the ball would end up striking when kicked from the drain, and that might result in damage. Just seems like there should be some clearance here. But if I provide any clearance all, the metal ball will not be detected.
So how is this thing supposed to work. Should the ball physically touch the Hall sensor? Is there an adjustment where I can "dial it up" and add the clearance so the ball wont strike the Hall sensor, and it will be detected propoerly?
