Hi,
My Miele G2670 dishwasher stops a couple of minutes into any cycle with a pair of F63/F84 error codes. I've stripped, tested and rebuilt the "slide shutter assembly" that is on the side of the circulator pump, the part the codes refer to. Encouragingly there were obvious signs of a leak from it that had shorted and corroded its wiring at the connectors. All cleaned up now and motor/rotation and micro-switch checked working off the machine, reinstalled and..... F63/F84 after two minutes.
Not sure what to do now as there seems little chance that and a replacement pump/shutter assembly is going to solve this. Also, I'm under domestic pressure because my hifi went wrong on the same day but I've fixed that.
Thanks!
PS Same thing happened a year ago and I was able to fix it just by opening the machine and staring at it really hard. Actually I think someone had posted quick fix using a button combination that worked and I can't find now. Anyone remember it?
