Lint Removal System The lint filtering system consist of the turbo pump, agitator, air bell, and self cleaning filter at bottom of spin basket. During agitate water moves through the sides and up from the bottom through the self cleaning filters. During pump down, prior to spin, the turbo pump is energized, and water is drawn out the sides and down through the self cleaning filter to clean and...
Control Panel REMOVE The control panel is designed with ease of service 4 SCREWS being the major consideration. The switches are tab interlock, and harness connectors are designed to only fit the correct mating connector. Control panel is galvanized, with three tabs designed to allow the switchtrim to be supported during service.
Timer The timer is a double switch bank, with polarized harness connectors. This insures that the correct harness connector will only fit the mating switch bank. Some models have only one switch bank, check mini-manual. Timer motor and timer are NOT interchangeable with the other timers.
Cabinet Cabinet is galvanized sheet metal, with powdered LOCATE SPRING CLIPS paint coating and is rust resistant. It has a fully ON EITHER enclosed bottom, and is 3 sided with a front panel. SIDE AND RELEASE The lid has patented colored lid instructions. The levelling legs are installed from the factory, and are WITH PUTTY KNIFE Polypropylene with Santoprene non-skid base.

Spin Basket (4) 5/16" DAMPENER DAMPENER SCREWS SCREWS To Service Spin Basket 1. Remove front panel and cover/lid. 2. Disconnect (4) dampening straps from tub, attached by 5/16" hex head screws. 3. Remove tub cover by lifting out 8 tabs on tub cover, and pulling cover off.
Motor and Drive System The new GE washers incorporate a new motor and drive system. The 120 VAC input powers a three phase induction inverter/motor assembly. The inverter produces approximately 340 VDC, which is pulse width modulated (PWM) to control motor speed. There is no location to check inverter output voltage to the motor.
Shaft and Mode Shifter Overview The shaft and mode shifter assembly consists of the shaft and tube, mode shifter cam, and mode shifter coil. It operates in 2 distinct modes, spin and agitation. The shaft and tube transfers power to the wash system. Motor power is transmitted to the shaft and tube from the drive belt to the drive pulley.

Mode Shifter Operation - Agitation The mode shifter is controlled by the motor inverter circuit. When the washer starts the agitation cycle, the inverter energizes the mode shifter coil. The magnetic field of the coil lifts the mode shifter cam, disengaging it from the drive pulley. Without the cam engaged, the drive pulley rotates only the agitator shaft.
Drain Pump Belt • Since the belt provides constant tension, there is The drain pump is coupled to a 120 VAC, 60 Hz, 85 no need for adjustments (an adjustment method watt motor. The pump motor has an approximate is not provided). resistance value of 12Ω.

Note: • A new belt will be slightly smaller than the drive pulley. • A belt that has been installed on the drive pulley will stretch to the diameter of the pulley over time. This is normal and does not indicate a bad belt. New Belt on Pulley –...
