(58.
INSTALLATION Choosing the Proper Location Install the washer on a solid floor that is strong and rigid enough to support the weight of the washer, even when fully loaded, without flexing or bouncing. If the floor has too much flex, you may need to reinforce it to make it more rigid. If the floor is not solid, it may cause severe vibration and noise. NOTE ••The washer must be installed on firm flooring to minimize vibration during the spin cycle.
INSTALLATION 11 Unpacking and Removing Shipping Material 2 CAUTION ENGLISH Unpack all shipping materials from the washer for proper operation and inspect it for shipping damage. To prevent damage, do not remove the foam block containing the owner’s manual, parts, and laundry product samples from the washer tub until the washer is in the final location. ••Failure to remove shipping materials can cause excessive noise and vibration. 1 Lift the washer off the foam base.
INSTALLATION Connecting the Water Lines To avoid the risk of costly water damage, purchase and install new inlet hoses when installing the washer. 1 Check the fittings and seals. Inspect the threaded fitting on each hose and make sure there is a rubber seal in place in both ends of each hose to prevent leaking. Rubber seal Water hose (to water inlet on washer) 2 Rubber seal Water hose (to tap) Connect the water supply hoses.
INSTALLATION 13 Connecting the Drain Hose Connect the drain hose to either a standpipe or laundry tub. 3 If the water valves and drain are built into the wall, fasten the drain hose to one of the water hoses with the tie strap provided (ribbed side on inside). ENGLISH NOTE ••The drain hose should always be properly secured. Failure to properly secure the drain hose can result in flooding and property damage. Tie strap ••Make sure that the drain hose is not stretched, pinched, crushed, or kinked.
INSTALLATION Leveling the Washer The tub of the washer spins at very high speeds. To minimize vibration, noise, and unwanted movement, the floor must be a level, solid surface. NOTE ••Adjust the leveling feet only as far as necessary to level the washer. Extending the leveling feet more than necessary can cause the washer to vibrate. NOTE ••To check if the washer is level from side to side, place a level on the back edge of the lid (door).
INSTALLATION 15 Connecting to the Power Supply WARNING ••Do not use a worn or damaged power cord or power plug. Replace or repair it immediately. Failure to do so may result in death, fire, electric shock, or malfunction. Check if the washer is properly installed and run a test cycle. 1 Make sure the tub is empty. Do not load anything in the tub for this test. 2 Press the Power button then immediately press and hold both the Spin and Soil buttons until an code appears in the display.
OPERATION OPERATION 4 Select a cycle. Turn the cycle selector knob or press the cycle buttons repeatedly until the desired cycle is selected. The preset wash temperature, spin speed, soil level and option settings for that cycle are shown. ••Pressing the Start/Pause button without selecting a cycle will cause the Normal cycle to begin immediately. 5 Adjust settings. Default settings for the selected cycle can now be changed, if desired, using the cycle modifier and option buttons.
OPERATION 17 Sorting Laundry ••The washer can be fully loaded, but the tub should not be tightly packed with items. The lid (door) of the washer should close easily. ••Use the Bedding cycle for buoyant or nonabsorbent items such as pillows or comforters. Failure to follow this caution can result in leakage. ••Clothing or articles that are waterproof or water resistant must be washed in the Waterproof cycle only. (e.g. water resistant clothing, mattress covers, outdoor clothes, plastic mats, etc.
OPERATION Loading the Washer ••Check and empty pockets. Paper clips, coins, matches, etc. can damage clothing and the washer. ••Close zippers and hooks, and tie drawstrings to prevent snagging or tangling of clothes. ••Use the Bedding cycle for large or bulky items such as poly-filled jackets, comforters, pillows, etc. These items may not be as absorbent as other laundry items and should be sorted into a separate wash load for optimal results. ••Combine large and small items in a load.
OPERATION 19 Adding Cleaning Products About the Dispensers ••Liquid fabric softener ••Liquid or powdered detergent for main wash Using the Detergent and Softener Dispensers To add detergent and fabric softener to the automatic dispenser: 1 Open the dispenser drawer. 2 Load the laundry products into the appropriate compartments. Liquid fabric softener compartment This compartment holds laundry detergent for the main wash cycle. Either powdered or liquid detergent may be used in this compartment.
OPERATION Using the Liquid Bleach Dispenser The bleach dispenser is a separate compartment at the left front of the tub opening. 1 Check clothing care labels for special instructions. 2 Measure liquid bleach carefully, following instructions on the bottle. ••High-efficiency washers use less water, so less bleach is needed. One half cup is enough for most loads. 3 Carefully pour the pre-measured amount of bleach directly into the bleach dispenser.
OPERATION 21 Detergent Use ENGLISH ••This washer is designed for use with only HE (HighEfficiency) detergents. HE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of the washer clean. Using detergent that is not HE may cause oversudsing and unsatisfactory performance which could result in error codes, cycle failure, and machine damage.
