Why is my appliance making loud noises and vibrating excessively during the spin cycle?

Loud noises, vibrations, and appliance movement during the spin cycle are typically caused by the appliance not being properly aligned, the feet not being secured, or the transport locks not having been removed. Check the alignment using a spirit level and adjust the screw-in feet as necessary, ensuring all four feet stand firmly on the ground and lock nuts are tightened against the housing. Also verify that all four transport locks were removed before first use. (Page 50)
