Delayed response, sorry. I have been travelling a lot recently. But thanks for all the replies and recommendations.
My FLO problem is still there but I have 'cheated' to make it less bothersome. As I was always able to reset the error by removing and replacing the SENSOR cable, I focussed on that aspect. The trouble doing that was removing the panels and putting them back on every time I wanted that reset. To make it easier, I cut the red wire of the FLO switch going into the circuit board and placed a spring loaded mini switch in series. Every time I saw FLO on the panel, I simply flicked the switch and everything reset. By flicking the switch, I am opening the flow switch momentarily for the reset to take place. I was able to mount the mini switch on the outside cover which then became easy to use. The tub would then run without FLO error sometimes for an entire day and sometimes just for a few hours. As I said it is a 'cheat'.
What I do hear everytime the reset takes place is some relay clicking, I dont know which. This brings me to SerjicalStrike's post on: September 11, 2017, 09:09:35 AM. He mentioned that "If you have the FLO error and the circulation pump is running, you have a bad relay on the board." Could you tell me how I can identify the faulty relay? Which relay? It sounds like that could be the root of my issue.
