thanks for the tip Dan

Hello,
Good news- I fixed my nipple , but unplugging the light didn't help I probably should buy a high limit thermistor?? They aren't that expensive and will eliminate that area. Please let me know any other tricks.
Thanks

I replaced the high limit thermistor, changed the filters and added new water, and it still just flashes!! Is there anything else to look at before I change the whole board??
Thanks

Oh man- what a bummer

How long does it take the red light to flash?

Hello,
When someone plugs in the power, the circuit board flashes the green led then the bottom red led(control head) for a second. Then, the power light flashes just after, then the spa control blinks all it's symbols, then just the power light keeps flashing.
Thanks
