Hello.

Can you please tell me the year of your Hot Spot? The serial number may be helpful if uncertain, it will be on a sticker inside the equipment compartment. Usually on the side wall inside there.

The U1, U3 ect...are upper temp settings. U1 is 105 U2 is 106 ect. it should go to 108. Hot Spot's way of getting around the 104 limit set by UL listing.

The flo error is likely a pump flow problem, filter clogged, or bad pressure switch. I can help you with that if you wish.

Do the jets work with the pump on? Will the pump cycle low/high speeds?

Standing by.
