5koliny Posted May 23, 2014 Report Share Posted May 23, 2014 Hello, I have an older MAS560 circuit board with M7 heater technology. It always says that the flow is low, but the circ pump that pushes water through the heater is running, and water is coming out of the outlet in the tub. The filters are brand new (3 days old). What could be the problem? Quote Link to comment Share on other sites More sharing options...
Loopcity Posted May 25, 2014 Report Share Posted May 25, 2014 Check your water level. If the level is much lower than the fill line, the system will not get enough water and give you that error code. There could also be some sort of debris in the lines. Otherwise, you may have a bad pump. Good luck! Quote Link to comment Share on other sites More sharing options...
