What do you mean whe you say it won't stay on? Is the display showing an error code or what exactly are the circumstances as far as how it's running?
The heater should turn on the low speed pump by itself, that's what it uses to heat with. If you're manually having to turn the pump on, then it sounds like your low speed pump may not be activating. Can you open up the spa cabinet to take a picture of the equipment area so I can guide you through some troubleshooting?
Ok got it, can you send one of the whole area so I can see all the pumps etc. Also, the one pump we'reinterested in particularly is that second chord that's labeled "circ pump" that would be the one that runs the heater.
Ok, yes the pump there to the left of the control box is the heater pump. Once you get the leak fixed and turn it on, make sure that pump shaft is spinning, then let me know. Thanks, jeff
Yes, if the gasket was in the pipe that went towards the heater, then it could create an air leak in the pump suction, preventing it from pulling enough water through the heater. Is it still not running the heater?
And when the heater turns off, you're not getting any error code at all? If all the sensors are working and you have water flo from the circ pump, you should either have a heater light on, ,or an error message saying what the problem is.
No, sorry, that's not it, but after I spoke with you around 2:30 I had to drive a couple hours to pick up my kids, so couldn't continue emailing while driving, but I'm back home on my laptop now
But here's the thing, if a spa pack has no error codes showing, and the circuit board still won't send power to the heater when it should be, then the only possibility in this situation is a bad circuit board, there can be nothing else. The boards have a high limit sensor, a temp sensor, a pressure switch sensor and two relays for the heater circuit. If ANY of the sensors are defective, either not closing, not opening or stuck in one of those positions, you will get an error code for that issue. Since we have no error codes, the pump is running water through the heater and the temperature is set higher than the water temperature, there's no reason other than a bad circuit board that it would not be heating.
