I have a similar problem except my heater will work fine when it's not in bypass mode.For future reference, many times error codes and other issues can be resolved by simply pulling all the wires from the control board one plug at a time and re-seating them. This allows some of the oxidation to be rubbed off the control board pins. I've had luck with this many times over the years. Older units will have a higher instance of this problem for obvious reasons.
I recently had a lighting strike it took out my easytouch my goldline salt generator and my protacol adapter. These have all been replaced, after all was replaced found heater keypad no response and would not come on. I replace the keypad assembly and heater will work until I place it into bypass operation then it doesn't work, so I replaced the intergrated control board and still not working. Any ideals would be appreciated
I have check all voltage points per Hayward. I have replaced keypad assembly with board I replaced the Intergrated control board. Check continuity on thermostats wires replace water and air sensors on easytouch. I might think termister but would think that would also cause it not to work when it's in stand alone. Any help appreciated
