You can also use a GE WD15X93 water inlet (or almost any of the GE style inlet solenoid valves to repair.
If you open the gray box on the hose of your Miele you will see a standard clamped hose connected to the inlet valve.
Unplug, cut the wiring at the valve, attach two spade connecters, connect GE valve, and attach wires to solenoid.
This will replace the solenoid for $20-$35 instead of the $200-$300 to replace the entire Miele assembly.
This is how I resolved this issue on my G870... works great
