Little Swan washing machine is normal when washing clothes, but abnormal when dehydrating.

Is it a fully automatic washing machine or a semi-automatic one? I think it is semi-automatic. There are foreign keys, change, screws, etc. In the dehydration barrel. Open the full cover of the washing machine and look at the internal and external dehydration barrels. Carefully check whether there are foreign objects in the bucket. If it is a fully automatic washing machine, it will be more troublesome. 1 is the inner gear of the dehydration differential, and 2 is that the bottom channel changeover valve is broken.
