R-C Posted December 4, 2021 Report Share Posted December 4, 2021 I have a 2006 Balboa M7 spa. I've been having DR & DRY codes for a while now. I've replaced the board the sensors and even the circulation pump. Spa starts to heat the water but I can tell my circulation pump is not running. There's power coming from the board to the pump but no movement which gives me the DR code. Also during prime my #1 pump stays running.
