The flap of the funnel has a piece of plastic that sticks out, which pushes on a microswitch under the top cover.. If the funnel is not seated correctly, it will not work the microswitch.. This will also apply if you try to use it with ground coffee.
There are 2 switches side by side, the other is for the bean hopper cover.
I suppose you could insert a small stick into the hole, and press towards the front of the machine.. it should have a distinctive click to it. if it works, then either the plastic piece on the ground coffee cover is broken, or the funnel is not seated correctly.. if it doesnt work, you need a new switch fitting.
