Hi hoping to get some help on what could possibly be wrong with my pool heater. We just bought a home with a pool and i have no experience maintaining a pool. The pool and system haven't been ran in over a year and a half so it goes without saying that the pool and filters were filthy. I went to local pool supply place had water tested, got new filters and have cleaned up the pool and water right. My Jandy is still showing the Low Pressure error and won't turn on, i've looked online and few people are saying that it could be the pressure sensor failing. I can't locate the pressure sensor on the unit to replace. Anyone who could help me out i would appreciate it.
