i am a hot tub newbie so go easy on me. we just got a 1993 hot springs sovereign hot tub. everything worked great. drained the tub and moved it to a new location. filled it and then plugged it in. jets and lights work. when i turn the temperature dial up i can hear the click but after 24 hours its not heating. i can feel the tub vibrating so i am guessing the circulation pump is good? i believe the heater has been replaced as the button labeled heater reset are just empty. from what i have read the new ones do not have this? its the 110v version. right now its hooked to a 15 amp circuit and i know it should be in a 20. could this be the problem or is it something else as nothing gets tripped and everything else is working. thanks in advance for any advice!
While Chas is correct in pointing you to check the reset buttons, I would also have you check to ensure everything is still plugged into the control box. I say this, because you indicate that the spa was recently moved. It is possible, however unlikely, that moving the spa might have loosened the heater plug from the recepticle.
If the circulation pump is running, you should be able to check flow out the heat register. If you can feel water pressing past your fingers there should be enough flow to keep the high limits from tripping. If the pump seems to vibrate and no water in coming out, your spa may have a air lock preventing the system from pumping and heating water.
