Thread: Myhot tub won't heat up
11-14-2013, 12:28 PM #1
I moved in a house with hot tub six months a go.
I tried to use hot tub, but it is power on but won't heat up.
The model is LA Spas (H82113-2006). 240V 4K watt.
these are what I have already tried:
there was a three dots error signal (flow error)
-replaced pressure switch (it was leaking and no conductivity and no power on heating element terminals)
-replaced heating element (because it's resistance was too low)
-replaced temp sensor and hi-limit sensor.
now with some adjustment of pressure switch, both heating element terminals has 240V power and enough current (17A).
i turned it on a whole day. it is still not even warm at all.
finally i called technician, he said the spa is mechanically OK, and configed the control panel.
-made sure the economy mode is disabled.
-the panel displayed the current temp is 32 F (he said the sensor shows only higher than 58F)
-the technician said it will take a day to heat up completely and I paid $99 yesterday
But today, it still cold....... x(
The panel shows only current temp 32 F. no flow icon. nothing operating.
No flow error sign either.
At this time no power on the terminal.
If i turn off and turn it on, the power goes to the heating element again.
What may cause to stop heating even though the temp is much colder than desired temp?
That is my final question.
Thanks for reading.

Do you have a circulation pump in this spa as well as a main therapy two speed pump? If not and the two speed pump is used to heat the water is pump overheating and shutting off? I am not sure what you mean when the technician says the temp sensor shows only higher than 58 degrees. The pump has to be running for the heater to have power sent to it. I couldn't open these pictures to see your controls for some reason.
