I just purchased a hot spring sx 2020 and it reads 104 and water temp is only 101, then after only having the lid off for 30minutes and not running the jets on high it dropped to reading 101 and so the temperature only being 97. We have had the technicians come out and they don't even check anything and then say well that's how it's supposed to be . Which makes no sense, We spent 7k on a hot tub so it would be hot. We also live in Louisiana so its not like its cold out and that's effecting it. Do you have any suggestions for me or some things for the technicians to check?.... We didnt buy this straight from Watkins, we bought this from Azura pools in Monroe,LA
