I have an AEG Favorit 88060 integrated dishwasher which is 6 years old. Today it didn’t drain properly and displayed an error code of iC0. I have checked the drain pipe and it is not blocked. The filter is also clear. I have reset the display, turned the appliance off for 2 minutes and tried running a wash cycle. Every time I have done this, I hear the pump run for a few seconds, then it stops and presents the same fault code. Any suggestions would be welcome.
