Now, a night later, I can start the spa and it starts heating, showing 11°C on the display. Now a small "Temp" also blinks there. However after a while it goes back to the four flashing lines. any thoughts?

Hi, I´ve just cleaned my Caldera Martinique spa, and after refilling it, I get four flashing lines on the display. I´ve gone through the manual, and followed the procedure of turning of the electrical current to the spa for over 30 sec and done so more than three times. But to no avail. There is a trick, I know, how to reset the "Heater high limit thermostat". But for the life of me I can't remember what it is This has happened to me before, then I overfilled the spa and tried to restart it in very cold weather. Problem is I can't get a hold of the guy who helped me then. Anyone remember how to proceed? warmest
