Fault Analysis and Maintenance: The causes of the fault and their troubleshooting methods are as follows:
(1) Imbalance during spin cycle
First, check if there is a fault in the mechanical system, then proceed with normal imbalance treatment. Short-circuit the safety switch (door switch) pins; if it can return to normal, it indicates that the contact pressure of the switch is insufficient, and the safety switch should be adjusted or replaced. If it cannot be restored, continue checking whether the connectors are loose; if loose, repair the connection and contact of the connectors to ensure they do not loosen during the spin cycle. If it's not a connector issue, it may be a computer board fault, requiring replacement of the computer board.
(2) Spinning with water
Check the water level pressure switch and the air circuit of the water level pressure (such as the return gas pipe) for leaks. If the water level pressure switch is damaged, replace the water level pressure switch.
(3) Drying turns into washing
First, check the clutch. If the clutch does not function properly, replace the clutch. During drying, the embrace spring should be able to hold the clutch sleeve tightly with the spin axis (separate during washing). Due to the embrace spring's inner hole being too large or the ratchet claw not opening, issues such as "drying turning into washing" may occur. When this phenomenon happens, adjust the position of the fork or replace the embrace spring. If still ineffective, only the computer board can be replaced.
(4) Intermittent spinning
Intermittent spinning may be caused by the following reasons:
① Program controller malfunction, Beijing LG Washing Machine Repair Center. If the program controller malfunctions, the computer board must be replaced.
② Wear or malfunction of transmission components. Inspect the transmission components, and if faults are found, replace the malfunctioning transmission components.
③ Loose power plug or connectors, capacitor, or poor soldering at the wiring connections. Check the plugs, connectors, and capacitors, and if any looseness or poor soldering faults are found, reconnect or re-solder them.
For LG washing machines, after turning on, common issues include entering an unbalanced spin cycle, spinning with water, drying turning into washing, abnormal work cycles, or intermittent operation.
