Why is my Fisher spa not heating?

If your spa has a Balboa controller it is most likely set to Ec mode. Ec stands for economy mode which means your spa will only heat during its filtration cycle. This may mean that depending on when you wish to use your spa, it will not be at its set temperature.

Change the mode on your spa to St (standard mode) by pressing “Temp,” then “Light”. Your spa will now proceed to heat up to the set temperature.
