It seems to me that someone may have tried to tinker with it and made it worse. Is there a wiring diagram somewhere?
The switches and pumps work but something is causing confusion behind those switches. Does that make sense? Its not a valve or a bad pump and I dont even believe a bad switch BUT maybe. I ordered new switches but I think its not wired properly to the switches.
I have 6 Tsunami pumps one to fill and one to drain each of the three bags.
