Alternating currents?

[Son Of Skyline]

Been there done that. One of my theories on it is that all the stop and go allowed dirt to collect, then score the impeller chambers bad enough cause the stoppage.

Keep in mind that my Hagen powerheads are ancient old, and it *may* be possible that 2 out of the 3 ph's have other problems too like bent impeller shafts.

Take it for what it's worth, but they always fired up right away until a month into using them with a wavemaker. So I guess it's also possible that the wavemaker didn't actually damage anything, but just stressed them enough to magnify the existing problems I already had with them.
