I have a Vertex 150 Omega that I purchased back in about 2014. Occasionally, when I turn off the power to the pump (cleaning, etc) then turn it back on, the impeller seems to get caught. I hear it make a sound as if catching. I then disconnect it from the skimmer and move it in the water to get it restarted. Then it will work normally. I cleaned it out but it still happens. Since they are no longer in business, is there anything I can do?
