My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.

This means one of the sensors picked up a high temp fault...likely when insufficient water went through heater and boiled...

If turning power off and back on does not clear it you will need to replace temp sensor.

When doing this I would replace all sensors if you have more than one one.

where are the temperature sensors located
Expert:  Billy replied 10 months ago.

I do not know which spa you have, but generally they are in wells in the pipe entering or leaving the heater assembly.
