Here is the proof that no one sees or hears because its hidden away in a cold and lonely laundry in Woolahra, Sydney.
This Washing machine in Woolahra I have repaired twice (yes 2 times) repair is not really the right word to use ‘maintained’ is a better choice .
So this W918 was purchased by a Family of 5 in 1995 and then the kids grow up,moved out and Miele W918 still washes the clothes of 2 .The first visit in 2006 was really an issue with the drain filter and I fixed this on the spot ,by then the Miele was 11 years old. The second visit this August 2013 the inlet valve failed and I replace this also in one visit , now the Miele washer is 18 years old and still washes.
So the calculated washing time is currently by 6552hr/cycles perhaps more (I used 7 washes (one hr per cycle) per week and times 18 years )
One of my favorite Miele Model W918 hot and cold water entry Germany built and serviced !
