had the spa shut off twice in the last 36h and looked through the fault log and saw a pair of fault codes of 19:
both times spa was in Ready Mode, Low Range with a Set Temp of 95. The most recent had an A/B reading of 83 and the previous one had an A/B reading of 75 (this was after a fresh fill of water)
any techs/reps know what that fault code means?
