Need help?Do you have a question about the LG FH6G1BAPK2 and is the answer not in the manual?
This document is a service manual for an LG Electronics Inc. washing machine, model FH6G1BAPK2. It provides detailed information on product features, new technologies, operation principles, component names and functions, service sequences, fault diagnosis, disassembly/assembly instructions, and a circuit diagram.
The LG FH6G1BAPK2 is a front-loading washing machine with a 12 kg wash capacity and a 7 kg dry capacity. It features a 6-motion washing tub for a hand-wash effect, optimizing washing performance for different load types and reducing wash time. The machine is driven by a BLDC motor controlled by an inverter, ensuring quiet operation and energy efficiency. It offers customized washing cycles to suit various lifestyles, including daily cycles (Cotton, Auto Wash, Speed14, Easy Care, Mix, Wool), special cycles (Allergy Care, Stain Care, Outdoor, Gentle Care, Direct Wear (1kg), Delicate), and dry cycles (Cotton Dry, Wash+Dry (7kg), Outdoor Dry, Easy Care Dry, Time Dry, Delicate Dry). A "Download Cycle" option includes Tub Clean, Refresh, Rinse+Spin, Turbo 49, and Spin. The machine also incorporates a heat pump drying technology, which uses less energy than conventional drying and minimizes fabric damage through an optimized heat exchanger and auto-cleaning.
The washing machine is equipped with a Smart ThinQ (Wi-Fi) feature, allowing users to remotely control the appliance, receive smart alerts, download new modes, and perform smart self-diagnosis via a smartphone app. A button lock feature (CHILD LOCK) prevents accidental operation. The low noise speed control system senses load amount and balance to evenly distribute the load, minimizing spinning noise. The door open control allows the door to be opened once the program is closed or paused, provided the water level frequency is 23.4 kHz or lower and the in-tub temperature is below 45°C. In case of a power outage, the door can be opened within 5 minutes if the in-drum water level is not excessive. The machine detects laundry weight at 5 levels for pre-wash and spin-dry, using this data to determine wash duration, remaining time, spin-dry algorithm, and unbalanced states. Water level control uses a sensor-type pressure switch and a flowmeter for precise water supply. The function operation panel includes a display window for wash mode, remaining time, options, and status messages, a settings window for features like screen lock and automatic detergent, and a wash/dry mode selector. Options include Soil level (Light, Normal, Heavy), Rinse (Rinse+, Rinse++, Rinse & Hold, Rinse+ & Hold), Temperature selection, Spin speed, Add Option (Turbo Wash, Prewash, Medic Rinse, Crease Care), and Add Drying (Cooling, Normal, Iron, Eco, Speed, Time Dry).
The service manual provides comprehensive guidance for maintenance and repair. It outlines a service sequence starting with listening to the consumer's fault description, checking power connection (220 V), and proper installation. Basic installation instructions cover transit bolt removal, ensuring the product is on a firm, even surface, and leveling using adjustable feet. Detailed steps are provided for connecting the water supply hose (checking rubber seals, connecting to screw-type or one-touch taps) and the drain hose, along with instructions for addressing odors from the standpipe. Power plug connection cautions are also included. A "Check Program" (LQC Mode) allows technicians to verify various functions like SW version, Wi-Fi/RF module connection, touch screen functionality, and component operations (tub turning, valve checks, heater activation, pump activation, spin speeds, detergent/softener pump, flow meter, heat pump components). The "Fault Diagnosis and Solution Matrix" helps identify and resolve issues based on error codes (IE, OE, UE, FE, PE, dE1, dE2, dE4, tE, LE, LE1, LE2, FF, AE) and provides possible causes and actions. Disassembly and assembly instructions are provided for various components, including the top plate, PCB assembly, main PCB, cabinet cover, door switch, door and hinge, heater, upper/lower frame, side cabinet, thermistor, housing assembly/blower, bellows/lint filter, duct assembly, pump, and detergent box. A "Post-repair Check" ensures insulation resistance, proper internal wiring, and absence of water leaks after service. The manual also includes a circuit diagram for electrical troubleshooting.
