SF is a thermistor or hear sensor error. If the heater is not reseting it self after a few minutes then you may need to replace the sensor. Yes you probally can do this. On the left side of the water header their is a small tube like thing that slides into the header. It will have two wires comeing from it and you will follow these into the heater and around to the front panel. When they get to the circut board you just un plug them and string a new one in it's place. Good luck.

Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.

AO will apply to your blower, blower tubing, or blower vacuum switch. You need to check these items.
