Front Load Washer Cleaning Video - Miele
Here's a video I made of how I usually clean my grandma's Miele washer. Being a true European model, it does not have a Clean Machine cycle.
What I do is run it through a boil wash with some citric acid and catch the cleaning solution at the end of the main wash. Then I switch over to spin and put the drain hose into the dispenser. When the machine begins its continuous spin cycle - no earlier - I add some of the hot cleaning solution via the dispenser. This aggressively and effectively cleans the entire outer tub and also the internal hoses.
I have done this on Bosch and Electrolux washers, too. Works very well and certainly better than just an empty hot wash because the spinning action gets the water everywhere.
