Frequently Asked Questions - FV1408S4V LG

What should I do if the washing machine displays an IE error?

The IE (Water Inlet Error) indicates no water or insufficient water supply. Check that the water tap is fully open, the inlet hose is not kinked, and the inlet filter is not clogged. If the issue persists, inspect the inlet valve resistance (should be 3.5-4.5 kΩ) and the connector to the main PCB.

How can I resolve an UE (Unbalanced Error) during spin?

An UE error occurs when the load is unbalanced. Pause the cycle and redistribute the laundry evenly in the drum. Avoid washing single heavy items or mixing large and small items. Ensure the machine is level. For small loads, add a few items to balance.

What does the OE (Water Outlet Error) mean and how to fix it?

OE indicates drainage failure. Check if the drain hose is kinked or clogged. Clean the drain pump filter regularly. Ensure the standpipe height is between 60-100 cm. If the drain pump motor does not run, check its resistance (3.46-3.98 Ω) and wiring.

How do I activate and deactivate the Child Lock?

To activate Child Lock during a cycle, touch and hold the Child Lock button for 3 seconds until a beep sounds and a lock icon appears. To deactivate, press and hold the same button for 3 seconds again. The setting persists even after power off.

Can I use the washing machine without removing the transit bolts?

No, transit bolts must be removed before use. Failure to remove them will cause excessive vibration and noise during spin. Use the spanner provided to unscrew the four bolts at the back of the machine.

How often should I clean the drain pump filter?

Clean the drain pump filter once a month to prevent drainage issues and odors. Open the lower cover cap, remove the hose cap to drain water, then unscrew the filter cap and remove debris.

What is the Tub Clean cycle and how to use it?

The Tub Clean cycle cleans the inside of the drum with high water level and spin speed. Remove all laundry, add an anti-limescale agent (e.g., Calgon) to the main wash compartment, select Tub Clean, and press Start. Leave the door open after cycle to dry.

How do I use the Smart Diagnosis™ feature?

If you experience a problem, use Smart Diagnosis™ via the LG Smart ThinQ app or by phone. For phone method: press Power, do not touch other buttons. Hold the phone mouthpiece near the Power button, press and hold Temp. for 3 seconds. Keep phone in place until data transfer completes.

What should I do if the door does not open after a cycle?

The door is locked during operation and for a short time after. Wait until the Door Lock icon turns off. If the door still does not open, check for a dE1 or dE2 error. If no error, try a power cycle. For emergency, you can manually drain water via the drain pump filter.

How do I connect the washing machine to WiFi?

Download the LG Smart ThinQ app from Google Play, create an account, and register your washer. Follow in-app instructions. Ensure your home WiFi is 2.4 GHz and the machine is within range. If connection fails, consider a WiFi extender.

9-2. DOOR LOCK SWITCH ASSEMBLY

Wiring diagram	Circuit in the MAIN PWB / Wiring Diagram
Function	The Door Lock Switch Assembly consists of a Heating PTC, a Bimetal, a Protection PTC, and a Solenoid. It locks the door during a wash cycle.1. Operation for door closing- After the system turns on, PTC heating starts up through terminal 2~4's authorizing the power on.- After PTC heating starts up and before solenoid operation is driven, force the system to the off position through CAM.⇒ Door close- Authorizing one impulse through terminal 3~4 (PTC & solenoid) will make the door lock.- Door lock is detected when switches in terminal 4~5 are set closed.⇒ CAM rotation will forcibly clear off the connection.The maximum, allowable number of impulse authorizations is 2.⇒ Upon the third authorization of the impulse, the position of CAM goes back to the door-open position.- Authorizing the impulse occurs in 4.5 seconds upon input for max performance and two authorization processes are allowed at most.⇒ Normal operation period of PTC heating: 1.5 – 5 seconds.(Defects from the development process.)2. Operation for door opening- With a temporary stop, door automatically opens by CAM rotations after authorizing the impulse from the terminal 3 ~ 4 and the power turns off – maximum of 3 times of the authorizing period.- Upon the fourth authorization of the impulse, the position of CAM goes back to the door-close position.
