I recently baught a used 2003 Sundance Optima hot tub off a guy after it had set for the winter. I have replaced the heater, hi speed pump, and flow switch that we're cracked from freezing. But now I can't get the flo error message to go away to get the heater to come on. As soon as I turn it on the flo error flashes, then after a hour it will start flashing a plug error every time. I have taken the filter out and bled all the air out, and I can see that the flow switch is operating and has flow. I tried to bypass the heater relay to test it and see if the heater icon would come on but it doesn't. Does anyone have any ideas? Thanks!

When you get the plug error code that usually means the topside panel connection is causing it. Turn the power off to the spa and replug the topside panel back into the circuit board. Do the same on the remote panel too and make sure cables to each still look good.
