Question about Pool & Spa
I believe I need to repair my peregrine industries pool heater - it is not heating the pool properly. It starts fine, but after a while, it comes up with an error message ''FLO'' on the control panel display. The message goes away when adjusting the temperature using the arrow key beneath the display. The water level in the pool was low, but after fillin it to the proper level, the message continued to display (as described above)
The Plate at the bottom of the unit, below the control unit has ARL inside of a hexegon and the number 013013.

SOURCE: Pool heater will not heat
Im no pro, but I know there is an air sensor behind the main board. If the fan is running you probably have a problem with that sensor. If your lucky the air hose could have just popped off.

I had this problem with ours last year. I replaced the water pressure switch and it began working fine. We later had a symptom that the blower would start but it would not ignite. The ignitor rod was corroded so I took it out and sanded it with some sandpaper---worked fine...until I dropped it trying to reinstall and it broke. Bought a new one and it works fine now.
Today's problem is related to the blower now.... it is always something, isn't it?!?

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:

You most likely have a bad water temperature sensor. Replace the water temperature sensor that is probably near the discharge side of the filter pump. That should take care of the problem.
