LG Washer Filter Replacement

Treating these as cleaning tasks rather than replacements is the whole point, because most LG "filter" service calls are just neglected maintenance. LG uses three screens, and knowing which is which prevents unnecessary parts and unnecessary panic.

The three screens#

• Drain debris filter (coin trap), front-load only — behind a small access door on the lower front panel, it catches coins, buttons, and hair before they reach the drain pump. Left uncleaned, it causes OE drain errors and eventually jams the pump impeller.
• Inlet-valve screens, all models — small mesh screens where the supply hoses connect. In hard water they clog with sediment and slow the fill, showing up as an IE error.
• Lint filter, older top-load only — some legacy agitator models have one in the agitator or tub rim; modern LG washers have none and rely on the drain filter plus the Tub Clean cycle.

Cleaning the coin trap#

1. Set towels and a shallow pan under the access door on the lower front panel.
2. Open the door, pull out the small drain hose, and uncap it to drain the residual water (often a cup or two).
3. Unscrew the filter cap counterclockwise and pull it out.
4. Remove all debris — coins, hair, buttons, fabric scraps.
5. Wipe the cap and housing, reinsert the cap and turn it clockwise until snug, recap the drain hose, and close the door.

Do this monthly, or after any load that sheds debris such as pet bedding or work clothes.

Cleaning the inlet screens#

Shut off the water and disconnect the hot and cold hoses from the back of the washer. Inside each valve inlet is a small mesh screen — pull it out gently with needle-nose pliers, soak it in white vinegar for 15 to 20 minutes to dissolve mineral scale, then rinse, reinstall, reconnect, and turn the water back on. Do this annually in hard-water areas or whenever the washer fills slowly.

When damage means a part#

These parts only get replaced when broken. If the drain-filter cap is lost or cracked, LG lists it as part 383EER2001A; the inlet screens come as a pair under 5230FR3158D. Otherwise, clean rather than replace. Skipping the routine has predictable consequences: a neglected coin trap restricts flow until the washer times out with an OE error and then jams the pump; clogged inlet screens starve the fill and throw an IE error; and skipping the Tub Clean cycle — LG suggests running it about every 30 washes — invites mold on the door boot and a musty smell in laundry. A few minutes of cleaning prevents all three.

Reading the errors and the Tub Clean habit#

The two most common LG washer errors map directly to these screens, so the code tells you where to clean. An OE code is a drain fault: the coin trap has restricted flow enough that the machine cannot empty within its timeout, and left long enough the debris moves downstream and jams the pump impeller into a real repair. An IE code is a fill fault: sediment has clogged the inlet screens so the tub cannot fill in time, and in severe cases no water enters at all. Alongside the screens, run the Tub Clean cycle roughly every 30 washes — skipping it lets mold establish on the door boot gasket and leaves a musty odor in laundry that no detergent fixes. Together, those three habits head off the great majority of avoidable LG washer service calls.
