Reason:
To avoid abnormal vibration,the machine will test whether the laundry was laid balanceable at the beginning of spin. If it is unbalanced, the machine will spin at low speed. To try to distribute to balance,if can not distribute to balance,it is not go to full spin speed.
Solution:
1. In case washing 1 piece of laundry(carpet, bed sheet,table sheet,ect) make it symmetrical inside the drum.
2. Lower the wet weight of laundry pieces by wringing manually and placing them back in the drum in symmetrical position.
3. Take out and then reposition the laundry piesces inside the washing machine in a more balanced position on the inner wall of the drum.
4. Add 1 or 2 pieces of laundry into the durm to reduce the unbalanced load effects.
5. Restart the spin cycle by cloosing spin programme.In case the failure persists,please ask a qualified technician to repair it.
