Direct drive technology results in fewer moving parts for smooth, quiet operation. (See Motor Assembly.) General The GE Profile Harmony Washer is part of the GE Profile Harmony Clothes Care system utilizing the latest developments in washing technology. The Harmony Washer does not use the typical agitator found on conventional washers. Instead, the direct drive motor, capable of spinning at 1010 rpm, and the 304 stainless steel wash basket create a centrifugal force that pulls wash water through fabrics for a thorough cleaning action. (See Operation Overview.) Harmony Washers also utilize an automatic load sensing system to determine load size and water levels. The washer automatically fills the wash basket with the appropriate amount of water needed for optimal wash performance. Other features include: Communication Link to the Dryer - The washer uses a serial cable to automatically inform the dryer about the nature of the wash load, essentially presetting the dryer controls so the user doesn’t have to. Auto-Balance Suspension - The washer is programmed to correct out of balance situations. (See Operation Overview.) Flow-ThruTM Dispensers - Each of the four dispensers is timed to release at the right time during the wash cycle. Each reservoir is flushed with water to predilute the product before adding it to the washer. This flushing action removes all product to help keep the compartment clean and free flowing. InfusorTM Wash - The washer has specific cycles that aid in mixing the detergent/water solution, and dispersing the load evenly in the wash water. (See Operation Overview). LCD Touch Screen Display - All washer control functions, cycles, troubleshooting, and field service diagnostics are accessed through a touch screen display. The washer can also be powered up by touching anywhere on the touch screen or any key on the keypanel. Centrifugal Wash - The washer uses a centrifugal washing action to clean clothes instead of an agitator. The basket spins, creating a strong flow of water under the centrifugal force. As water passes through the fabric, its natural cleansing action washes away dirt without damaging or tangling the fabric. Plastic Top & Backsplash - The washer top and backsplash have UV stabilizers to prevent yellowing when exposed to sunlight. Sales Demo Mode Press HOME and MY CYCLES simultaneously for three seconds to enter into the sales demonstration mode. This mode allows the user to view a wash cycle. The Demo Mode will last approximately 11/2 minutes. To exit the Demo Mode, press HOME and MY CYCLES simultaneously for three seconds or disconnect the power to the machine. Note: The bleach dispenser fills during the main wash to dispense the bleach and refills during the rinse cycle to flush any remaining bleach from the reservoir.

After a load is placed in the basket, the user selects the appropriate wash cycle on the LCD touch screen and presses START. Note: Dry load and wet load sensing are used on all cycles except the following: SNEAKERS COMFORTERS BLANKETS (OTHERS) BLANKETS (COTTONS) THROW RUGS (WASHABLE) The SNEAKERS cycle defaults to the minimum water level. BLANKETS, THROW RUGS and COMFORTERS cycle default to the maximum water level. Cycle time and wash patterns will vary depending on user time adjustments, soil level adjustments, fabric type, and wash-load weight. Wash Water Temperature Dry Load Sensing During the fill, the washer monitors and regulates wash water temperatures within 5°F (-15°C) of the target temperature. This accuracy is achieved using a thermistor, located in the outer tub, which monitors the tub water temperature during the fill cycle. Before an initial fill, the infusor rotates the dry clothes load. This rotation is controlled by the inverter which measures the amount of time it takes for the motor to coast to a stop. The larger the clothes load, the less momentum the motor is capable of generating, so the faster it will stop. The infusor will rotate back and forth up to four times. This information is used to determine the initial water fill level. Based on information received from the thermistor, the inverter controls the hot and cold inlet valves to achieve the desired wash temperature. (See Thermistor/ATC Control Auto Temp.) Water Fill The washer automatically fills to the proper level based on the load sensing measurements. Depending on the cycle chosen and the quantity of clothes, there are 27 possible water levels. This information is stored in memory for the final rinse at the end of the wash cycle. Water levels are matched to load size using approximately one-third less water than typical top load washers. Note: The washer can use as little as 17.5 gallons of water for small loads and has an average water use of 27 gallons per load. Wet Load Sensing After the first fill, the infusor and basket lock together and rotate to measure the clothes load. During this time, the motor momentum is measured again. The washer compares this information to the previous dry load sensing measurements and determines if additional water is required. Target Water Temperatures: Very Hot - 140°F (60°C) Hot - 112°F (44.5°C) Warm - 80°F (26.5°C) Cold - 63°F (17°C) Tap Cold - Consumer’s incoming water temperature. During the fill, the basket slowly rotates in a clockwise direction. This action mixes the detergent and water to assure proper distribution and assure the thermistor is reading an accurate basket water temperature. Basket Wash The infusor and wash basket lock together and rotate clockwise and then counterclockwise. This action mixes the detergent and water while distributing the clothes evenly in the wash water. The basket wash speed is based on fabric type and load size. Delicate fabrics are gently rotated while heavier fabrics are rotated more vigorously. – 17 – Centrifusion Wash Spin The locked infusor and wash basket begin a clockwise spin (figure 1). The speed of the spin is customized to the load type and fabric type. As the basket spins faster, it creates a strong flow of water under the centrifugal force (figure 2). The infusor and wash basket lock together. The basket spins very slowly at first. This allows dirty wash water and lint to drain through the holes in the bottom of the basket before a higher spin begins. When the washer senses that the excess water has drained, the wash basket accelerates to a higher speed. Spin speeds are adaptive to fabric type that is selected by the user on the LCD touch screen. They can be as slow as 350 rpm for hand-wash items and up to 1010 rpm for heavier items. The spin is designed to extract as much water and detergent as possible without harming fabrics. As water passes through the fabric, its natural cleansing action washes away dirt without damaging or tangling the fabric. Fabric Note: During the spin cycle, excessive suds can cause excessive torque on the motor. If the washer detects this condition, it will run through the rinse, drain, and spin cycle (up to three times) in an attempt to eliminate the suds. Soil Water Current After several seconds of clockwise spinning, the basket slows down and stops. The wash water pools back into the wash basket. The wash basket starts spinning in the counterclockwise direction creating the same cleaning action. The washer will change direction (up to four times) before going to the next cycle. Note: The washer is programmed to correct out of balance situations during spins. If the washer senses an out of balance load, the spin is stopped. The washer then refills to allow the infusor wash cycle to redistribute the load before starting the spin again. The washer attempts to rebalance the load three times before optimizing the spin to a lower speed where balance is sustainable. Spray Rinse The infusor and wash basket turn at a slow speed while fresh, clean water is added to the wash load. The spin cycle then drains this rinse water and prepares the wash load for a final rinse. Final Rinse Infusor Wash Following the centrifusion wash cycle, the basket and infusor unlock. The infusor rotates to evenly distribute the wash load while continuing to clean. The redistribution of fabrics helps ensure that the lint and dirt do not become trapped. The washer retrieves the information it gathered for adaptive fill cycle and uses that information to refill the washer for the final rinse. Cold water enters the basket through the fabric softener dispenser to dilute the softener into the basket and rinse the dispenser clean. The wash basket fills to the optimal level and goes into a basket wash cycle where the clothes and fabric softener are mixed thoroughly. A final spin finishes the cycle. Note: All rinse cycles use cold water and the Automatic Temperature Control (ATC) is not used. The cold rinse is the same temperature as the incoming cold water supply. – 18 – Wash Cycle Chart Example User Selection of Cycle Dry Load Sensing Water Fill Wet Load Sensing Adjust Water Temp Adjust Water Fill (only if needed) Wash Process Basket Wash Centrifusion Wash Infusor Wash Spin and Drain* Spray Rinse *Spin Information Maximum spin speeds will vary depending on the cycle: Spin and Drain Final Rinse Spin and Drain Hand-wash Delicate Normal Vigorous 350 rpm 500 rpm 1010 rpm 1010 rpm • The Delicate cycle ramps up to maximum speed by first spinning at 400 rpm, pausing, then increasing speed to 500 rpm. • Normal and Vigorous cycles ramp up to maximum speed by first spinning at 400 rpm, pausing, increasing rpm to 750, pausing, then increasing speed to 1010 rpm. – 19 – Component Locator Views Balance Ring 304 Stainless Wash Basket Tub Cover Infusor Note: To operate the washer with the lid open, place a magnet on the left front corner of the top cover (in front of the bleach dispenser).

Brake Resistor Protective Cover Brake Resistor • The brake resistor absorbs energy from the reversing of the motor during the brake cycle. • The brake resistor only operates when the washer is unplugged or the lid is lifted during a cycle. • Under normal operation, the tub coasts to a stop at the end of a cycle. • The approximate resistance value of the brake resistor is 70 Ω. • If the resistor is shorted, the motor will not start. • If the resistor opens while the motor is spinning, the inverter board can be damaged. • Look for a burnt IC, labeled IC300, on the inverter board. Both the resistor and inverter board should be replaced if the IC300 is damaged. (See Testing the Inverter photo.) – 26 – Pressure Sensor (Water Level Switch) The pressure sensor is connected by a clear hose to an air reservoir near the bottom of the outer tub and operates by a frequency (kHz) signal to the inverter board. The frequency is monitored by the inverter which turns off the water valves when the desired water level is achieved. Note: The water level will vary depending on the load size, which is measured by the dry load and wet load sensing cycles. This information is sent to the inverter, which then determines the appropriate water level.
