Thread: dr code
05-05-2013, 02:47 PM #1
I have a 2003 Bullfrog spa. I replaced the heater element. Now I get a dr code. The pump is pumping well I have removed the filter but still no luck. I read that there can be an air lock but can't find how to fix. Any suggestions? Thanks!

If you just slightly loosen the pump union nut just enough to allow water to trickle out for a little bit it will release any air that could be trapped in the pump. Then tighten back up and run to see if it improves.
