markwindsor Posted October 12, 2018 Report Share Posted October 12, 2018 Hi I moved to place that has hot tub. Everything works except for one issue: When the hot tub gets to its default temp the display flashes 3 red dots and then it starts too cool off. Blowers and pumps continue to work, but depending on how cold the outside air is, it starts to drop in temp. The only way to get it to go back up is to turn it off and back on (from the breaker indoors or from the fuse box). Then it heats up until it gets to temp and then begins to cool off. If anyone can suggest what part of the system needs replacing, please let me know. It would be a BIG help to get this solved without resulting in a 400$ service call.
