It is normal for a small amount of food to remain stuck on the sides.
However, if a lot of food is clumped and sticking to the sides and you hardly remove any fertilizer from the bucket, this may be caused by adding too much very sweet, starchy, or very damp food.
To avoid this problem, avoid adding such foods in large quantity during a cycle and avoid exceeding the maximum fill line. For best results, it is important to mix a variety of food waste with each cycle and to follow the recommendations in the article on acceptable materials.
