Nordic Hot Tub Problem

[kellyann]

Hi,

I have a nordic hot tub, I emptied before vacation, came home cleaned and filled it up. I have all three of the lights flashing below the temp and the light above temp where the,I think, heat sign flashing. I've put in a new filter, filled it with water in the carteridge area, made sure all the valves are open. I read and reread the instrucition manuel and called the dealer who was no help either.

Any suggestions. I emptied and cleaned the tub myself for the last 3 years and this is the first time I've had problems.

The 3 flashing dots is a flow error of some sort that it is sensing. You have checked some of the stuff....Is the tub moving water? If not your pump may be air bound. Loosen the pump union a little to let the air out. leaving dry while you were gone for vacation may have allowed the pump to dry and lose its prime.

If it is moving water fine but there are 3 flashing dots and just not heating, it may be the pressure switch. You can try to adjust this, if it works you should still get a new pressure switch because it will be a temporary fix.
