Installation INSTALLATION REQUIREMENTS DRAINAGE A vertical standpipe with an internal diameter of 1-1/2” Cable tie (3.8 cm) is required. The standpipe height above the floor must be: Minimum height: 36” (91,4 cm) Maximum height: 96” (243,8 cm) Insert the drain hose into the standpipe and secure it with the cable tie located inside the accessories bag.
Flow Logic automatic drawer dispenser. Your washer is equipped with an automatic dispensing system, comprised of a drawer with 3 compartments: Bleach Detergent Softener Liquid bleach Pour liquid bleach into the designated compartment with- out filling beyond the mark. Check clothing care labels for special instructions. Use less for smaller loads.
HydroSoft Infusor Washer Tips INTRODUCTION HydroSoft model washers use an Infusor , not a traditional agitator. Infusor wash technology provides excellent cleaning. Infusor models are ENERGY STAR® qualified using only 23 gallons of water per (super) load compared to 48 gallons for a similar load with a standard machine .
UNDERSTAND THE CONSUMER’S ISSUE FIRST Lint Do not overload the washer. Use the Deep Rinse option, adding more water, to reduce lint. Not filling or low water level Infusor models are designed to use less water and are ENERGY STAR® qualified. During the wash cycle, water may not entirely cover the top of clothes.

All models have the PreciseFill Automatic Load Sensing feature. When PreciseFill is selected, the machine determines fill time by sensing the load size. The Precise Fill pressure switch minimum level setpoint. The lower level setpoint is attained at approximately 1 inch of water depth, at which point the washer will start sensing the load size and determine the optimal amount of water required and corresponding water level.
Page 17
Water temperature Energy-star requirements dictate that even on a hot setting, the washer will mix in some cold water. If the home water supply pipes have a long run, are imbedded in a concrete slab, and/or the washer is used during the winter months, it may take longer for the first hot water to reach the washer.

Note: The motor, pump and was motor can be service from the bottom without remov- ing the cabinet. The next step in removing the transmission (mode shifter), it is to remove the belt and the motor. The belt can be forced over the transmission pulley. - Remove the belt.

NOTE: 14- Remove the pump to prevent it from getting damaged, It is held in pla- ce with 3 (1\4 “ screws) 15– Remove the wax switch 16- Remove 12 (3/8) bolts holding the transmission base to the outer tub. 17- Once the base is removed, release the wire harness plastic retainer.
ATC Thermistor The ATC controls the water temperature selected by the customer. If the ATC thermistor fails or harness is broken, the washer will still operate. The control will open just the cold water valve. At room temperature ( 20ºC) , the resistance should be approximately ~11KΩ. Resistance goes down as temperature goes up.

How to Enter or Exit to Service Mode 1. Unplug the washer. 2. Turn the Cycles knob to POSITION 6 3. Re-plug the washer pressing Start/Pause and Options buttons at the same time for 3 seconds. Display will show “LLL”. Service mode function 1.
ERROR AND FAULT CODE Warning and Error Codes A Warning code appears when a failure has been detec- ted. After displaying a Warning code for 30 seconds, the washer will attempt to resu- me the cycle. If the failure persists, the Warning code will be shown once again. If the washer is able to resume the cycle on its own, Warning code will disappear from the display and NO SERVICE IS REQUIRED.
