HydroSoftTM InfusorTM Washer Tips INTRODUCTION HydroSoftTM model washers use an InfusorTM, 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 . High efficiency (HE) detergent is required with Infusor models. Liquid HE detergents dissolve faster in water.
UNDERSTAND THE CONSUMER’S ISSUE FIRST 1. Lint Do not overload the washer. Use the Deep Rinse option, adding more water, to reduce lint. 2. 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. If Super size load is selected, the water level will be just at the top of the Infusor. Check for water supply hoses pushed up tightly against a wall.
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. Use the Deep Rinse option to add more water during rinse. 3.
6. 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. Run the hot water at a nearby faucet to check water supply temperature. 7. Vibrating/shaking Check for proper levelling. If only an occasional complaint, check for out-of-balance load. 8.
Wash Cycle Progression Level detection/ Overload sensing Clothes arrangement Fill to Minimum Water Level (Sensing Level) Load Sensing Fill to selected level Washer starts by sensing if basket is over loaded. Washer executes pattern to set the clothes previous to agitation in order to improve wash performance. Water and detergent are admitted in this stage between tub and basket; at the same time water circulates intermittently 6 seconds each 45 seconds detergent dilution.
Wash Cycle Progression (cont.) Level detection/ Overload sensing Takes 2 spins, measures time to reach a certain angle. Estimates if load is greater than 17 lbs or not. If load is greater than 17lbs, it bypasses the "load arrangement" phase and goes straight to the pre-fill portion. Washer executes pattern to distribute the clothes previous to agitation in order to improve wash performance. Clothes arrangement Load spins 2 times (CCW-CW), each time injecting cold water for 8 seconds.
Wash Cycle Progression (cont.) Load Sensing Washer agitates to determine if water level (as selected by consumer) is appropriate for actual load size and type of clothes. •After minimum water level is attained, washer senses if load is greater than 17lbs (impeller only goes back and forth). • Basket is spin intermittently by pulses (3 times CCW, then 3 times CW) and water is injected via the dispenser, dispensing soap.
Wash Cycle Progression (cont.) Untangling Soft agitation pattern for 3.5 min. in order to detangle and balance clothes previous to spin. • Washer agitates at different rate than main wash to set the clothes in place for spin, for 3.5 minutes. Drain Drain the wash water, until the minimum water level setting is reached (no agitation). Intermediate Spin pattern consist of a series of speed ramps until maximum speed is reached.
Wash Cycle Progression (cont.) Shower rinse is the normal rinse cycle. However, in some instances the washer will go to a Deep Rinse instead: •when fabric softener is used and customer has selected the Deep Rinse option. •on certain cycles such as Bulky Items. •if the washer recognizes that a higher water level than the one selected by the consumer is required to ensure proper operation of the washer.
Shower Rinse Progression The water is sprayed on the clothes while basket spins inter- Fills with water up to level selected for main wash (or adjusted by the washer if insufficient) Admits directly in the wash basket a predetermined water amount (approx. 3 gal @ 20 psi). Water amount is determined by time (approx 40 seconds per block). Clothes Saturation 1 (fresh water) Basket stop to 0 rpm Water Admission Directly Drain & Spin Waits until the basket stops completely.
Deep Rinse Progression Fills with water up to level selected for main wash (or adjusted by the washer. The water is injected on the clothes while basket spins intermittently. 4 minutes of agitation. Agitation pattern same as wash cycle. Clothes Saturation 1 (fresh water) Basket stop to 0 rpm Water Admission Directly Agitation Waits until the basket stops completely.
Final Spin • Washer start draining until "minimum" level is reached. • After level is reached, washer starts spinning basket, ramping up to 400 RPM • Washer then slows down to 230 RPM, then ramps up to spin speed selected by consumer • If washer CANNOT reach desired spin speed, motor shut off until speed reaches 300 RPM • After reaching 300 RPM, washer attempts to ramp up to final spin speed again.

INFUSOR REMOVAL 1- Remove the cap 2- Remove the bolt 3- Removing the Infusor TRANSMISSION REMOVAL NOTE Use a 3 ft by 3 ft floor protector under the washer to avoid damaging its components or the floor when separating the tub assembly from the cabinet.
3- Remove the tub cover 4- Remove the tub nut 5- Remove the basket Use a tub wrench (WX5X1325 ) to remove the left hand thread tub nut. Same wrench used on a GE washer. Note: When re-assembling, use a hammer with the wrench to tighten the tub nut. Hand tighten with the wrench then ¼ of a turn using a hammer. 6- Suspension Before the outer tub is released, unlock the main harness and the drain hose clips. Release the drain hose from the cabinet so both components can be separated.
Note: The motor, pump and was motor can be service from the bottom without removing 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. 9- Remove the belt. (The belt can be forced over the transmission pulley). 10-Rmove motor 11- Remove the pulley and shifter gear. (Use lock ring pliers to remove the lock ring that holds the pulley to the transmission.
NOTE: 14- Remove the pump to prevent it from getting damaged, It is held in place 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. Transmission removal is now complete The transmission is a complete sub-assembly including the base as shown in the picture.
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. NOTE: The ATC is activated Only during main fill.
Water valves & Drain Pump Testing Water valve • With harness disconnected the resistance value of any of the 4 water valve coils should be approximately 1KΏ • The water valve can also be tested with a 120 Volt test cord. Testing Drain Pump • With harness disconnected the resistance value of the drain pump should be 15Ώ • The pump can also be tested with a 120 Volt test cord.
Wax Motor and Motor Sensor SPIN Testing Wax Motor • Wax motor can be tested with a 120 Volt test cord. • Should take approximately 45 seconds to fully as described above.

Shifter System SPIN. AGITATE Wax Motor Shifter 120 VOLTS APPLIED Driving pulley With the wax motor NOT energized, the washer is ready to Spin. 39 With the wax motor energized the washer is ready to agitate.
Motor Sensor The speed sensor in the motor operates on a 10 vdc signal from the control board. The control board reads the pulses from the motor to determine proper operation. This signal can not be read with a conventional multi-meter while operating. Besides diagnostic error code mode – disconnect the sensor harness from the control and read AC millivolts on the sensor harness while rotating the spin basket CCW.
Lid Lock Step 1 Step 1: Current is applied (120 VOLTS AC) to terminals 4 and 2 (neutral) when any cy selected before pressing start. • • This energizes the bi‐metal but does not lock as the cam prevents it from doing so. The lid should not be locked at this stage. If it does press the start button to unlock. • Locking pin does not drop as the cam prevents it from doing so.
Lid Lock Step 2 Press the START button to begin the wash cycle. Power is sent to terminal 3, activating the solenoid, turning the green cam 30 deg. Then locking pin falls in place, closing the circuit at terminal 5, sending a signal to the board that the lid is locked. This terminates power to terminal 3. The lock signal from terminal 5 to the board now allows the motor to run.. Note: The board looks for this lock signal with a pulse up to 5 times. If it does not receive this signal it will show F8.
Lid Lock Step 3 • Lid remains locked until the end of the final spin (or until the pause button is pressed) and the motor has received feedback of 0 rpm from the speed sensor (Hall effect sensor on motor). • To unlock the lid, the PCB sends pulses (usually 2) through terminal 3 to activate the solenoid, turn the cam to disengage the locking pin, and open the circuit to terminal 5.
Lid Lock Step 3 (cont.) •If the PCB still detects power through terminal 5 after a few pulses, the PCB will emit a maximum of 5 pulses to disengage the contact and cut power through terminal 5. If this fails, the control will indicate a Failure code F8 • Unit will then attempt the sequence, a maxium of 2 other times (3 in total). If the lid still can’t be locked, an ERROR code Er8 will be shown and unit no longer operate until unplugged and replugged or serviced.

ERROR AND FAULT CODE Warning and Error Codes A Warning code appears when a failure has been detected. After displaying a Warning code for 30 seconds, the washer will attempt to resume 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. After 3 unsuccessful attempts to resume the cycle, should the washer be unable to continue an ERROR CODE will be shown.
HOW TO CHECK SOME COMPONENTS You can check different components from the plug underneath the top of the washer. 1 6 2 3 4 5 7 8 1- Lift up the top. 2- Unplug the main connection. 3- Do the test.
