Thanks GGG for the reply and the helpful info. I have on forwarded your thoughts to Bill Veale for him to double check the pin and motor connections, as well as trying another conventional re-set.
I'll let you know how it goes, once I have heard back from him.
By the way......do you have a PS3 boiler board just hanging around your workshop that would like to emigrate to a nice "smoke-free" home in sunny Queensland, Australia???
