M500sesp Posted April 12, 2020 Report Share Posted April 12, 2020 I am getting the watch dog 4 dashes. It is actually getting to hot. Up around 125 When it’s set at 102 i have replaced the High limit thermistor, the pressure Switch, and the topside control panel. I didn’t realize it was actually getting to hot. I also used the system flush and drained it and rebalanced the chemicals. The filter is about 6 months old and clean. is there a thermostat in these units? I haven’t seen anything for parts that I could replace other then the heater. thanks! Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted April 12, 2020 Report Share Posted April 12, 2020 Make? what control system is in the spa. Overheat can often be the filter cycle set wrong and the pump running continuously and overheating. Heating the spa from inside. Remove filters until issue fixed.

RDspaguy Posted April 12, 2020 Report Share Posted April 12, 2020 Hot Spot by Hot Springs. Does it show the current temp accurately, or does it say it's lower than actual temp? Quote Link to comment Share on other sites More sharing options...

It happens so rarely... It's like a treat or something. I can picture you slapping yourself on the forehead like an old V-8 commercial, you know the ones.
