This is probally a high limit warning. If you have a reset on your heater it is probally popped out. If you have drained the tub latly this may be caused by an air lock in the pipes and can be remeied by opening the drain **** on the bottom of the tub till you get water out of it. If your pump or motor has gone bad you will get these same simptoms. If you have no reset on your heater you may have burnt the element and will need to replace it This a symptom not the real problem. You need to check these other things first and be sure you have moving water before you try the heater. I hope this helped and good luck.

wow! That heater that you have is meant for a very large swimming pool, quite a bit oversized, i bet i gets the job done quick though. I have seen before that somebody plumbed in a heater backwards, there are elevated arrows on the black manifold of the heater, make sure inlet and outlet are plumbed in correctly. Make sure you get your water tested. Because the water in your hot tub is no circulating as often (I assume) as a pool would be, the stagnate water sits inside the heat exchanger. What can happen, for instance, if you have high calcium, is the certain tubes inside the heat exchanged can get so clogged with calcium and they are completely shut and the banging noise is due to excessive heat build up inside the heat exchanger. This can ruin a heat exchanger very quickly and the heat exchanger is half the cost of the heater if you were to get a new one. You can check and see if tubes in the heat exchanger are clogged by taking the manifold off of the heat exchanger, and shining a flashlight down the different tubes. However you have to disassemble quite a bit to actually be able to do that.

I agree it sounds like a check valve. if the water in the pool matches the water level in the spa, or drains all the way (depending on how far the spa is raised) then it is the valve before the pump, but if it goes down to the jets (and not any further) then it is a check valve or valve on the retun side of the plumbing ( after heater or chlorinator).

SOURCE: Tub is not heating to
the Ec message is reffering to the mode the tub is set for. Ec stands for Economy mode. In Economy mode the heater will only come on during the filter cycle you have programmed. It will take a while for the tub to actually heat up in this mode. Change the mode to St mode which stands for Standard mode. Your manual should explain how to do this. usually you hit the temp button then the light button to change from mode to mode. Once the St is in the read out window don't touch anything and it will except the programmmed entry automatically. In the Standard mode the tub will keep heating until the set temperature is reached. then it will come on every half hr or so to check that the temperature is maintained.
