Tech help needed

That's exactly what it's doing Reg, I'm dumbfounded. I'm trying to work with the seller who lives in Korea, so there's a bit of a language barrier. They say it was properly tested and has no issues. I beg to differ. Hopefully they will take it back and fix it up. I noticed the hydros were pretty spongy and air bound. Could it have some type of safety switch that disables the pump or something?
