I had the same problem. The water sensor is on a pipe running into your pump. It will have a circular clamp around it. Remove the clamp and pull the sensor out of the pipe. The wires should run into your control box. disconnect the wires and replace. My water sensor was part 7790. Not sure if you have the same one. Do an online search. bestbuypoolsupply.com has them for $50 plus 9 for shippng. Hope this helps.

I am not sure if you have solved this issue, or not, but here is one idea. When you turn on the heater, it is reading the temp at 125/126 correct? IF this is what the heater is reading, then the problem is the Thermistor,or temp sensor, and is very easy to replace.
If you have an Owner's Manual, there are part numbers and instructions on how to replace the Thermistor. If you do not have one, follow the link below and it will take you to one online:

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.

Assuming you don't hear any banging noises, that cycle is by design. There is a fault. 2 possible causes are the ignition board is bad, or the ignition sensor is not returning a voltage indicating the flame is lit. Take this out and put the ignition piece on your stove flame. Check for voltage while on flame (DC millivolt setting on multimeter). Put one probe on ground other on sensor lead. If it doesnt have voltage this is bad. If you do, its possible your board is bad.
