What to do if Hot Spot Tempo TEM display reads - - - -?
- TThomas HaleAug 19, 2025
If the display of your Hot Spot Hot Tub reads - - - - and the entire spa is inoperative, it indicates that the heater high-limit thermostat has tripped. To resolve this, disconnect power to the spa for at least thirty seconds to reset the heater high-limit. If tripping continues, clean the filter, and if tripping still occurs, call for service.
