Hello all,
I have a Sundance 780 Hot Tub. I believe it is a 2008. 3 pumps; 1 main 2 speed,1 main single speed and the Circ/heat pump. My tub has the Ozonator.
I just noticed the FL2 error flashing. Here are some symptoms
-FL2 Error Flashing
-Circ pump (heater) is always running (will not turn off)
-Current temp is reading 96. I have it set at 90. Heater will not turn off.
-I set the temp to 100 and the red light does come on and it does heat.
-Main pumps seem to be working fine.
-I cleaned the filer which is fairly new, ran with out the filter and power cycled the tub. Still get the error.
I understand from several of the post I have read that the FL1 and 2 errors are related to a flow switch being stuck.
Would a faulty flow switch cause the circ/heat pump to continuously run -or - is the continuously running circ/heat pump causing the flow switch to be open?
Can I tell by looking at the switch if it's stuck/faulty?
Any recommendations on how to test? I am willing to try about anything before I call someone out.
