New to the forum. I have a 2004 Sundance Bahia hot tub. I have been struggling with a fl1 error. I have replaced the flo switch and the the circ pump but still get the fl1 error. I have taken a power washer and blown the lines. There was a lot of hard calcium in the lines. The flow out into the tub is OK but not powerful as it was when new. The intake has good suction. I have burp the line many times and the flow switch looks like it is moving like it should.
The error happens with no filter in.
I am at a loss.
Can the heating element go bad that I have should replace it? I have had a technician out they are at a loss.
What are my next step? Help please.
