Hoping someone can help with this. I keep getting an error code E6 on my SMEG dishwasher. This suggests it is not draining properly. I’ve done a manual drain to empty teh machine and can get the machine starting again but it just starts filling (rather than draining) and fills the machine to the top of the filter unit before switching to code E6 again. I’ve tried repeatly to get it to start a new program or cancel the current program but it just refuses. It seems like the machine has got itself a bit confused. Any suggestions greatly appreciated. ALterantively, any recommended service agents for South London (SW2) greatly appreciated.
