Question about Jandy Pool & Spa
If using a controller see if heat is enabled if ok make sure red light calling for heat if not try jumping firemans switch to bypass controller if heater lights controller or temp sensor in controller if no heater working issue in heater
There is a row of plugs beaneath the solenoid pack. One of those is a rev pressure port. If reverse is gone, I am betting on a broken internal part.

I believe you may have a draft restriction and this may stop the start up diagnostics. The draft detection switch is sometimes restricted or weak. Common problem. Tap the gas valve to see if the winter has caused the valve to seat heavily and stick.

Page 34 and 35 of your manual, found here, describe FL0 as a flow issue most likely caused by dirty filters. Depending on the type of filter you have a good cleaning/backwash will usually remedy that. It is also possible the unit's pressure switch, which senses water flow and therefore reacts to dirty filters when present, may have failed, especially if you winterize the heater in a cold climate and leave water in the switch which can burst the diaphragm inside.
Start with cleaning the filter. If the heater still won't fire jump out the pressure switch while the pump is running to confirm the part is the problem. Assuming it is replacing it with a new pressure switch which should be under $75. The part number can be found in the rear of the manual.
