Filled and started the hot tub last week. Had a blinking FLO on the panel. I'm an engineer, so I investigated. The circulation pump was not working. So, today I replaced the circulation pump. Water flowing. Now I have a continuous solid FLO on the panel. Local Sundance dealer said the flow switch was bad. So, I replaced the flow switch. Still have solid FLO showing on panel. I can see the toggle is touching the electrode bar (vibrating on it actually). So, what do I do next?
Also, I pulled out the filter (which is new) and ran it for a while. FLO still on control. I also used a hose on the filter suction port to flush out any air. The toggle in the flow switch is touching the electrode post (vibrating on it actually). When the pump is off, the toggle is not touching the electrode po
