Trouble Shooting Trouble Shooting Vibration during Spin Had all 4 shipping bolts and/or packaging materials not removed? Remove all shipping bolts and/or packaging materials. Is the washer installed on a pedestal? If the brackets are not installed properly, noise and vibration may result. Be sure to remove the paper backing and to use all screws to install the brackets. Once properly attached, Firmly press the top part of the bracket to ensure that double-sided tape sticks firmly on washer or dryer. There are two kinds of brackets. The bigger one is for the washer; the smaller is for the dryer. If small brackets are attached to the washer and vice versa noise and vibration may result. Note: There is only one bracket after January 2006. Dryer Washer (Large) After Jan. 2006 Pedestal Brackets Or if brackets are correct Four brackets should be securely attached.

Trouble Shooting Trouble Shooting Vibration during Spin using leg spanner If the washer is on the pedestal, you should adjust pedestal legs. Use level. If the customer does not have a level , OK! Next step How to check and level the washer Diagonal Test : Important !!! When pushing down the edges of the washing machine top plate diagonally, the machine should not move up and down at all.( Please, check both directions.) If the machine rocks when pushing the machine top plate Diagonally, adjust the feet again till machine doesn't rock. During the diagonal test, if the washer moves at this test then adjust front leg in direction shown in picture. ( If opposite, adjust opposite front leg) Turn the leg clockwise by 45 degree, and do diagonal test again. If the washer still moves, repeat turning leg clockwise by 45 degree till the washer does not move at all Clockwise Adjustment to make higher How to adjust leg -- 45 degree method!! After adjustment fasten Lock nut (Turn counter- clockwise) Lock Nut Yes No Prime 31/32
Trouble Shooting Trouble Shooting Vibration during Spin Is the floor flexing or bouncing? Do you hear or feel the vibration throughout your floor? (Especially for wooden floor) Move the washer or reinforce the floor to make it more rigid. If the floor is not solid, your washer may vibrate and you may hear and feel the vibration throughout your floor. Refer to the owner's manual and installation instructions for floor requirements. If possible,place a machine in the corner of the space. Does vibrations occur intermittently according to the size and type of items in the washer? Vibrations result from the unbalanced load in the machine. As drum spins in an up and down rotation, the proper balancing of the load inside the drum is very important for the drum to spin smoothly. If the load is not evenly distributed across the drum surface, there will be more weight in some areas and less weight in others. So when it reaches the higher RPM the drum will spin slightly out of alignment. Try to redistribute the load across the drum surface to reduce the vibrations. Are there any foreign objects under the legs? If there are foreign materials between the legs and floor, It can cause vibration and also result in washer movement during operation. So remove the foreign materials and level the washer by adjusting the legs. Foreign objects No No No Yes Yes Yes Prime 32/32
