Welcome to our forum.
How did you know for sure the ozonater wasn't working? I am making the assumption that since I cannot see any bubbles, it isn't working even though its light is on. What model did you have that the ozone went out on?Thanks
I tried what PKUD said to do with the air lock. No bubble came out of the heater return.I powered the system back on, turned on and still no bubbles coming out of heater return.I can tell warm water is pumping out as evident by the ring at the water line, but no bubbles at all.Any other ideas?, thanks everyone for your input thus far.
