I have a Miele G641 dishwasher that must be around 15 years old now. It has just developed a fault where it stops part way through a cycle and flashes the red inlet/outlet LED. The heater element never seems to come on - or maybe it just doesn't get that far. It makes it all the way through the pre-wash (no heating) cycle OK though. I managed to download the fault code after finding a post on how to do this. It has flagged an error at 6 o'clock. Can anyone help me on what fault that is?
