Last month my pool / spa was complete. It is an in ground pool with a salt chlorinator. I am a first time pool owner so please bare with me. It has a pentair easy touch panel in the house. I turned on the hot tub tonight by pressing the interior spa button. 15 minutes later I go outside and the hot tub was empty no water at all. What could cause this? Since the filter ran with no water in the hot tub should I be concerned?
Thanks in advance for your help!
