The washing machine for home appliances to the countryside produced by Chengdu Limin Electric Appliance Co., Ltd. is normal when the impeller rotates forward, abnormal noise when it rotates backward, normal dehydrator and normal engine.
It may be caused by the deformation of the pulsator when washing a lot of clothes. Try replacing the pulsator. If there is a big reason, it is the clutch. If you want to replace it, the cost will be higher.
You can test it first: artificially short-circuit the water level switch, start washing without adding water, and conversely see if it is abnormal; Stop the machine and cut off the power supply, remove the impeller and try again. If there is no abnormal sound during reverse rotation, it is caused by the deformation of the impeller. Otherwise, the main problem may be the clutch.
