GE Consumer & Industrial Service Bulletin LAUNDRY ALL “HYDROWAVE” MODELS HL 01-07 FEBRUARY 2007 MOTOR-INVERTER DRIVE SYSTEM – 2 FLASH INVERTER BOARD ERROR (MOTOR APPEARS DEAD) This service bulletin is to notify technicians of a potential cause for a 2 flash error on the new Motor-Inverter drive system. The 2 flash error was intended to represent a slipping belt condition as identified in the mini-manual. Based on field feedback, a loose hub nut may also simulate the conditions that the inverter uses to detect a slipping belt condition. Because a slipping belt presents a safety concern for the machine to brake/stop normally, the inverter disables the motor while setting the 2 flash error code. The motor will not agitate or spin in this condition, so the motor appears DEAD. A loose hub nut may be obvious in severe circumstances where the basket has damaged the balance ring, the tub cover, or the tub. In some instances, it is more difficult to detect if the hub nut has not fully backed off. NOTE: The HYDROWAVE drive does not have a mechanical brake like the drive system with transmission. The basket may rotate freely depending on the state of the mode shifter assembly. It may require closer inspection of the hub nut. If the threads of the nut are damaged, the nut will not hold the tub securely. Always replace the hub nut if any damage is noticed. Tighten the nut to 110 ft. lbs. MODELS: 2006 and 2007 models listed subject to change with future production. 57751H0WW EWA5600G0WW GHDRE527H0WW GHDSR316H0WW GJRR4170H0WW GJSR4160H0WW GKSR3140H0WW GNSR3150H0WW GWSE5240H0WW S3700G0WW VBSR3100G0WW VWSR4160G0WW WBB4500G0WW WBSR3140G0WW WCCB1030F3WC WCCD2050F3WC WCRD2050F3WC WCRE6270G0CC WCRE6270G0WW WCSR2090DCWW WCSR2090G1CC WCSR2090G1WW WCSR4170DCWW WCSR4170G0CC WCSR4170G0WW WDSR2080DCWW WHDRR418G0WW WHDSR316G0WW WISR106DGBWW WISR309DGBWW WISR409DGBWW WJRE5500G0WW WJRR4170E6WW WJRR4170G0CC WJRR4170G0WW WJSR4160G0WW WLRE4500G0WW WLRR5000G0WW WLSE4000G0WW WLSR3000G0WW WMCD2050G0WC WNRD2050DCWC WPRE6100G0WT WPRE8100G0WT WPRE8320H0WT WWSE5240G0WW Procedure for repair: 1. Remove the agitator and agitator coupling 2. Inspect for damaged components (replace as necessary) 3. Tighten the hub nut with a torque wrench or impact gun (current factory torque setting is 110 FT-LBS) GE Appliances General Electric Company Louisville, Kentucky 40225 GE CONFIDENTIAL AND PROPRIETARY INFORMATION–NOT FOR PUBLIC DISCLOSURE N.D. 2110 HL-01 Clearing Motor-Inverter error codes: HydroWave Washer Customer Education 1. Disconnect the washer from power and wait approximately 15 seconds (hear a click/capacitor discharge) 2. Reconnect the washer to power and allow the relay to click (approximately 2 seconds). 3. Open and close the lid 5 or more times (in any 12 second period within the first 30 seconds of power up) The new drive system design is also creating a high number of Customer Education calls. The calls are primarily in two areas: Washer Performance (not agitating) and Washer Noise. These CE calls are an excellent opportunity to contact the consumer and discuss what operating characteristics and sounds are normal. Making the consumer aware of what is normal may save the service call. • The consumer doesn’t think the washer is agitating because it’s too quiet. They don’t realize the motor has to sense the load and engage the drive, which takes 20-30 seconds after the tub has filled with water. Have the consumer throw in an article of clothing, let it run for a minute and then open the lid. They should see the article has moved around if the washer is agitating correctly. • When the consumer hears the mode shifter engage and disengage they hear a “clicking” sound and assume it’s broken. This sound is normal and occurs when the washer goes in and out of agitate and spin. The consumer will hear this multiple times throughout the wash cycle.
