CRussian Posted June 11, 2017 Report Share Posted June 11, 2017 Hello all, I've replaced the filters, the oxygenator, and the heater. I know both pumps are working. I set the hot tub at 101 last night, when I came out this morning, it was stuck at 94 and there were 3 blinking lights at the bottom of the display. Anyone know what causes this? Is it an error? Thanks in advance. Cary Quote Link to comment Share on other sites More sharing options...
