I have come across this today and can find no mention of this error code on my usual searches.
I am hoping someone may have experience with this code in case there is something I am missing.
Machine shows error code within seconds of turning the power on, before a cycle is started
This model doesn’t have a pressure switch, just a flow meter in the inlet valve and a float switch in the base, both of which seem OK.
I suspect it is an electronics failure which id probably going to make it BER as machine is around 12 years old.
