Hey guys I have a question. I am new to hot tubs so excuse my lack of knowledge. I inherited a Jaccuzzi Essence 345 used tub which was exclusively used indoors. The tub is in great shape and I am not having to many issues with the water however I noticed that throughout the day and night the tub turns on for roughly 45 -60 seconds then turns off and this seems to happen every few minutes. I did notice that the tub is going through the 2 hour filter cycle in the morning however I cant confirm if it going through the 2 hour filter cycle 12 hours later as stating in the manual. Any ideas as to why this is happening?
