i have a caldera moorea spa and i was having the same issue with the temp light flashing and by turning the thumbwheel a turn on the pressure switch it took care of the problem, but i am sure it will need to be replaced sometime, which is a simple task

The low speed pump will not come on to enable the heater circuit to engage and the display still flaashes temp.
