Thanks. The original problem was the heat sensor was reading 104 when the water wasnt warm and accordinly it wouldn't heat. I tried replacing the sensor and switching the sensor from the other sensor but that didnt fix it. Presently the pump won't turn on, but I am not sure if it is because the hottub is displaying the snb error which the manual indicates is spa has shutdown because of B sensor. I was hoping to turn the pump on as I agree that could help show the leak. I guess I was surprised if there was a leak it was this slow with cold uncirculating water (I understand water does leak slower when cold and I am in the northeast so if I had to guess the water is somewhere between 45-55 degrees. I had a slow leak I think before the heat problem which didn't bother me as I just added a couple of inches each week. Hottub is outside so it isn't really hurting anything with its leak. I guess I was trying to figure out how much a difference either hot or pumped water might make toward the leak.

I have a bullfrog hottub where it would not properly keep temp. So a new mother board was needed. Cost to replace is around $1000. This happened outside in the winter and I drained the hottub just with the regular drain and did not pump out any water at the bottom. Presumably, it froze. I filled the hottub at it is keeping water fairly well (loses like 1-2 inches a week, which it did before I had this problem anyway). The company who was going to replace the motherboard said the hottub is ruined because it froze and therefore something would have broke and it would leak. He also indicated it would leak a lot quicker if it was hot. The water is still cold. He suggests replacing the hottub with something else. Do people think it is worth repairing the motherboard? I figured if something was really wrong it should have drained itself fully by now, not just lose a couple of inches, at most, in a week. Hottub is I think like 5-10 years old.

My temperature display is showing 104+ and the water is cold. It won't heat because I can't set the temp above that. But more importantly, what do people think is the best way to fix this inaccuracy? I am not getting any error codes from the hottub. I figure it is either the sensor, circuit board, or control panel but my model doesn't allow me to see the individual temp sensor readings. I assume there are two sensors based upon the instruction manual but I didn't actually look at the circuit board or able to see where the sensors are located. Advice? Thanks.
