I am not a dedicated white goods man, just a jobbing electrical/electronic engineer, but a friend asked me to look at Miele W698 that is very slow to fill, and the Miele website doesn’t seem to list the model
I would suspect a poor inlet solenoid but haven’t had the top off yet to look. I was hoping to find a parts list or better yet an exploded diagram, so knew what I was looking for, but google has failed me
You may be lucky when you take the top off,to find a diagram of the machine tucked away on top of soap drawer,if not there its usually behind the front panel.
It could well be the inlet solenoid,or it could just be a kink in the inlet hose.
also check the small filter in the solenoid when u unscrew the hose
