DRIVE SYSTEM: The bi-directional PSC motor provides agitation and variable spin speeds via pulsed power. The non-serviceable, belt-driven transmission connects the motor to the agitator and basket through a splutch mechanism.
SPLUTCH: This component, made of five parts, connects the agitator to the pulley and the basket to the transmission via inner splines. A cam ring controls the engagement of the basket drive gear to the pulley teeth, allowing the basket to spin with the agitator.
ACTUATOR: This synchronous motor shifts the splutch slider, monitors its position, and includes a transmission speed/position optical sensor.
LID LOCK MECHANISM: Ensures the lid remains locked during operation for safety. It includes a switch to detect lid closure, a latch solenoid, and a switch to confirm the lock.
CONTROL PANEL: Features include an ECO MONITOR for energy/water savings, a Wash Cycle Knob, Cycle Options, TEMP control, Soil Level adjustment, and Spin Speed selection.
Troubleshooting and error codes
| TEST # | DESCRIPTION |
|---|---|
| TEST #1: Main Control | Checks incoming and outgoing power to and from the main control. Involves checking DC voltages, LED status, and connectors. |
| TEST #2: Valves | Checks electrical connections to and functionality of the water valves (Cold, Hot, Oxi, Fabric Softener). Involves resistance checks of valve coils. |
| TEST #3a: Drive System – Shifter | Checks connections, shifter motor, switch, and optical sensor. Involves checking basket rotation, connector seating, and shifter motor resistance. |
| TEST #3b: Drive System – Motor | Checks the motor, windings, wiring, and start capacitor. Involves AC voltage checks during rotation and resistance measurements of windings. |
| TEST #4: Console and Indicators | Checks the cycle selector knob, indicators, buttons, beeper, and display. Involves UI test mode and checking connector seating. |
| TEST #5: Temperature Thermistor | Checks valves, main control, temperature thermistor, and wiring. Involves checking water valve operation and thermistor resistance. |
| TEST #6: Water Level | Checks water level sensing components, primarily the pressure transducer. Involves checking for automatic valve shut-off and hose integrity. |
| TEST #7: Drain Pump | Checks for obstructions and the drain pump's electrical connections. Involves manual drain test and checking connections. |
