Hi All -
We have a 2001 Sun Dance Tango - stopped heating - FL1 error as well
Both Hi and Low works, bubbles included, light is fine - FYI
Replaced filter
Replaced flow switch
Replaced full heating unit
Bled all air out
Power off and on numerous times
Prior to all of this the circ pump died and I just bypassed with new hose - I was hoping to run without circ pump - is there anyway to "jumper" the circ pump out of the normal operation on the board or elsewhere?
