Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

This error indicates inadequate water flow through the heater. Try cleaning the any pool filter strainers. Backwash the filter if necessary. Turn the heater off first then back on once you're done. I'm not available for a phone call.
