Disconnect the mains plug from the socket outlet. Remove any remaining beans in the bean container and take it off by twisting in an anticlockwise direction. Lift the bean hopper from the housing. The grinding ring can then be lifted out of the machine.
A soft-bristle brush is ideal for cleaning the grinding gear. Re-assemble the machine by replacing the parts in reverse order. The housing and transparent parts can be cleaned easily using a damp cloth.
