I have 30k in ground w/spa. Having trouble with Pentair minimax plus 400.
With heater in spa mode and valves in pool mode, Heater fires up and runs fine. But if i put valves in spa mode? Heater shuts down after a couple minutes. Move valves back to pool? and it fires back up.
I have thoroughly cleaned heater and filter/baskets, no obstructions. Both hi&lo limit test ok for resistance. Pressure witch did not. Does this mean pressure switch is bad?
