Balboa - continuous filter cycle

Balboa 2005M7 control system. Problem is water is in continuous cycle with blower (dual pump system) . Have made sure Filter cycle is set to FIL2 so it shouldnt cycle all time. Blower light is on and cant change this. Temperature of tub is 39C when it is set to 30C (its hot here but water temp should drop in evening but doesnt much. Have tried putting into sleep mode but after a while it defaults to ECON mode and water temp doesnt drop. Any opinion if there is a real fault on the control system or ideas what else it might me. Am getting a technician to check it out but would like to be prepared as to what he might say as I only want to change unit if absolutley necesssary.


Any help appreciated....

This sounds like you are having a problem with the spa circuit board (http://www.hottubworks.com/SpaParts/ElectricalCircuitBoards.php). The technician should also verify that your incoming power has the proper voltage going to your spa.
