If the grinder is noisy and not grinding beans there may be a stone from the coffee beans in the grinder. The following steps will rectify the problem:

• Remove the beans from the container.
• Use a vacuum cleaner to remove any foreign objects from the bean hopper.
• Refill with a small amount of beans, and deliver a coffee to ensure the blockage is cleared.
• Press the one cup button to check the grinder is clear.
