Tub: Diamondback Spas with Balboa EL2000 system.
For some reason my heater is shutting off early. On the topside it is reading 104 but it definitely is not. I have the heater where the 2 sensor is on the heater itself.
I check the 2 sensor ohms and its both at 41. The heater element is at 10.9 ohms, and the heater is getting 240v. Im guessing the sensor is "reading" the temp at 104 and is shutting off the heater.
I tried unplugging the 2 sensors from the board and resetting it, but when i turn it on it still had a reading ranging from 91-104? Shouldnt there be no reading or an error code since the sensors are disconnected? Sometimes it will start with a 91 degree reading and in about 10 minutes it will jump to 104.
What could be the problem? Bad topside? Bad board?
Any help is greatly appreciated.
