I have a 2004 HotSprings Prodigy Model H that goes in to error mode (red blinking light on control panel and heater stops heating) when after about 30 seconds or a minute after turning the jets on. It will also happen if I turn the lights on (but not jets). I figured out that if I turn the temp setting down so the heater won't go on that the jets work fine and run continuously. I tested the amperage draw of the jet pump and it was right at the rated amperage of the motor. I've had the spa about 2 years and I have been able to run both the heater and jets and lights until recently. I've also tried the standard protocol of removing the intake filter to make sure it wasn't a flow issue. Any thoughts on where to look? I don't mind replacing the control board, but I don't want to spend the money if that's not the issue. Thanks in advance.
