I found and repaired a leak in a plastic connector to my Jacuzzi J-345 Hot Tub, but not before the water level dropped below the filter, sucked air and tripped the 60amp breaker. After repairing the connector and refilling the tub to the proper level, I checked operation and everything seemed fine at first but now notice the circulating pump stops working. I noticed the flow switch was open which is in series with the 12ov power supply. I turned on the #1 pump which closed the flow switch and started the circulation pump again but the pump stopped working when I checked it later. The system seems to cycle normally and there are no error codes as yet, but I know the circulation pump is supposed to run constantly. is my circulation pump going bad (most likely)? Is the system air bound or is another problem affecting it? please help.
