I have tried these steps and my red light is still blinking. When I look at my circuit board, D17 is lit and nothing starts outside of the circulation pump. Any idea what D17 on the circuit board could be?

D17 means your spa is in High Limit Trip or Protection Mode. If you have tried every single one of these things and still have a flashing power light, call our tech support at 805-541-900 and speak to one of our technicians. You may have a motherboard issue. Thanks!
