Miele dishwasher red inlet light flashes
This is most probably a software glitch. I had the same issue a week ago and my dishwasher is only about 2 yrs old and only gets used on average once a fortnight.
At first I did everything as the manual shows in the troubleshooting section. The whole process takes only about 5 to 15 minutes depending on how good of a handyman you are.
When I cleaned all the parts involved (all pretty clean to start with anyway) and connect them all back, sadly the red light wouldn't go.
It looked like I was stuck with the most hated option I had left: call the dreaded technician and be prepared to depart with some hard-earned cash.
Before doing that and out of desperation, I decided to surf the net for clues, blogs, forums, etc... and on one of them I found my answer.
One blogger suggested that "if anything else fails, try the 'reset' step" which means pressing at the same time the On/Off button and the Start/Stop button. That operation put a big smile on my face (and my wife's face too) as the red light magically disappeared.
My suggestion is "first try the reset trick and if that fails try and clean the parts as the manual shows". It'll save you headaches because the reset would do the trick in 90% of cases.
I work in IT and I can understand the fact that a software malfunction would trigger the red light and not reset it.
