8 times per week?
That's average I'd say. I'm curious as to what cycle mostly?
My dad has the same Bosch and after 3 years, the detergent dispenser didn't work, and after the 4th year, the control board fried. My dad used to run it half full daily on the hottest cycle.
It's still in his kitchen, inoperable, but my sister lives there alone now, and she is in no hurry to remodel yet.
