I've just had one of them thoughts that make you smack upside your head...
SWCG is definitely faulty... and it doesn't matter what the salt level is.
It was working fine when I went away for a few weeks. During this time it didn't rain and no one used the pool. So even if the salt level had just dropped below the cut off level, adding 100kgs would have definitely taken it back over the threshold even with a decent bit of hysteresis .. at least I know where to start fiddling now...
Of course I still have to sort my pool chems out at the end of the month.. but the salt level quandary has subsided...
