I will post pics of the circuit board tomorrow in the daylight. Also I did remove the filters and I have replaced them with new ones or are you suggesting pull them out and run it awhile? Also I’ve noticed a weird kind of clacking noise for a second in what appears to be the circulating pump then no noise at all then the lights start flashing again

The hot tub is a 2007 grandee GG

The red power light and ready green light just flash. The pumps work. The clean cycle works but I can’t hear the circulating pump anymore. I hear a kind of clicking noise around the circulating pump. We just acquired the house and tub and learned a bout water levels being maintained and filters clean. Don’t know if it’s an obstruction or if the pump has failed
