  1. I have a Hayward H250 Natural gas heater and I just replaced the bypass assembly to the newer model as the old one broke. I am now getting the LO code. * Filter is Clean * I have let the pump run for 2-3 minutes to reset the heater ** Only concern is maybe the red and blue wire going to the back of the water pressure switch. I can not find a picture. The heater worked before installing the new bypass kit but it would ping and make loud noises due to the broken bypass part. Any help would be great Daniel
