In this video, I will show you how to fix the Miele CVA 6401 coffee machine error fault F77. This is a moderate simple repair that you could do it yourself. This F77 error is often caused by a faulty ceramic valve motor or DB3 microswitch. But most of the time, it is like the microswitch that causes the problem. The switch is only a few dollars to buy so it will be a cheap repair if you have the time and patience. We’ll guide you through inspecting the valve for rust or corrosion, testing the microswitch, and replacing either component if necessary. Fix it yourself and save money on costly repairs!
