In most spas the dots or dashes are an indicator of watchdog...this is a code for the sensors that are either not working or out of calibration. You need to replace the Thermostat and high limit sensors and reboot the system and the spa should be good. The high limit sensor is usually on the heater housing and the thermostat is usually near the filter or near the heater as well.
