Maybe the pump is going and there is not enough pressure to pull the water through? You had the same results with your other pump. Good luck.

Thanks Lee9. Now I have discovered that the pin wheel impeller has broken. For the time being I will install a regular Maxi Jet impeller. Then I can see if I can get the unit properly primed and running while I try to get a replacement impeller.
