Hi. I live in NZ and have a Hayward Aquarite+ unit and salt cell. It has a pH and ORP probe. When my ORP drops to the set point, the salt cell starts producing chlorine. However, it just never stops. If I stop production by dropping the unit set point down to less than measured ORP it shuts off. The ORP then steadily rises over about 24 hrs to an appropriate level. I've left it alone to see what happens, and I just end up with an over chlorinated pool (as measured on dipstrip and pool shop water analysis). I have changed the ORP probe and still it persists. The local pool shop have been great, but, nonethewiser. Hayward have also not provided a solution. Anyone here found the same AND solved it? Thanks in advance.
