What should I do if no ground coffee comes from the grinder?

First, check that there are coffee beans in the hopper and fill it if empty. If the grinder chamber or chute is blocked, clean and clear them. If there is water or moisture in the grinder chamber and chute, clean and clear them and ensure the burrs are thoroughly dry before reassembling (a hair dryer can be used to blow air into the grinder chamber).
