Not exactly sure, but I've just had a similar problem. I replaced the Flow diaphragm, as it was leaking - reducing the pressure and soaking the electric control panel - it seems to be working OK at the moment. Have you checked the system pressure?
I'm just running a bath to test if it's fixed. Let you know if it's not..... Damn, it's shut off again. I'llkeep trying and let you know if I fix it.
