I have a Sundance Altamar 2004, I keep getting a FLO error

Customer Question

I have a Sundance Altamar 2004, I keep getting a FLO error code, I have a newish flo switch that I have checked and it works fine and the circulation pump works fine as well. The issue seems to be that the circ pump is not coming on as it is suppose to, switching the power off and on occasionally get the circ pump going and it will work for a short time. Any ideas on the cause?
JA: How old is the appliance? Have you gotten error messages before?
Customer: It's a 2004, had this issue before and replaced the flo switch which resolved it for quite a while.
JA: Do you plan on doing the work yourself?
Customer: If possible.
JA: Anything else we should know to help you best?
Customer: Have replaced the 2 speed pump and circ pump but that was quite a while ago.

Do this test....Turn off breaker and remove filters from the spa completely, turn on breaker and see if the FLO goes out, if so the filter can be just dirty enough to cause the flow switch to open and cut out power to heater. You can not see the dirt on filter as it may be organic. The other issue I have seen is a clogged circulation pump, the impeller in the pump gets clogged with debris and does nt push enough water through the heater and flow switch.
