My spa keeps displaying the OH error. I have changes the Temp and High limit sensors and I have ran it with out the filter. I was wondering what else it could be. I have also replaced the Heater as it did not work.

If you have good water flow going through the heater from the pump and both sensors are new it may be the circuit board causing it.
