Hello friends, I need your help, afraid I'm about to lose my lovely (old!) Hot tub. I haven't used it in a week, and the weather here in Canada has been really, really cold (-4f today). I just went out out to check on it and found that it's not running, the water temp is in the 50s and falling, and there are three red dots flashing under the temp screen that I've never seen before. Picture and video is attached I got the tub, a Trevi infiniti, second hand, so don't have a manual, and now it's evening time I can't call a service person. I fear by the time I can get someone out here, all the water will have frozen in the pipes. Can anyone help?? Many thanks in advance PXL_20230203_215050320_TS.mp4
