Actually, there are two types of this error fault code.
One if the word Flo is flashing, and the other is if the word Flo is solid.
2 different problems:
if flashing, intermittently with current temperature, then the problem is 'Restricted' water flow. Most common problems:
Solid Flo - flow switch sensing water flow and confirming this to circuit board. But.... Circuit board is saying, whoa, hold your horses! How can that be? I am not even sending power to the pump, to create water flow! So, because of this confusion, I am going to throw up a fault code, that is going to be a solid Flo with no flashing temperature and render the system non operational.
So, which one do you have? Or did have?
if this help you out, please reply with problem fixed in the testimonial. Thank you, have a fantastic afternoon.
Hi Simon,
The FLO message is a warning that your water flow is not what it needs to be. This can be harmful to your equipment, without proper water flow the heating element can over heat or your pump can run dry causing damage. Often this is can be caused by dirty filters, so your first check should be to see if your filters are clean. Other possible problems could be water levels. Make sure you have no water blockages especially on the suction end.
