LG Washer Leaking from Dispenser or Not Dispensing Detergent? Bellow Hose 4738ER1004B – Fix Dispenser Failures Fast

If your LG front-load washer is leaking from the detergent dispenser area, leaving detergent residue in the drawer, or failing to flush detergent into the drum, the dispenser bellow hose is the most common cause. In most LG front-load washers, this flexible rubber hose connects the detergent dispenser drawer to the wash tub, carrying water, detergent, and fabric softener into the drum during each cycle. When it cracks, splits, or disconnects, water leaks out before reaching the tub and detergent is left behind in the drawer. ⚡ One of the most common leak sources in LG WM, WD, and F series front-load washers. Part 4738ER1004B is the genuine OEM LG replacement that restores proper detergent delivery and eliminates dispenser-area leaks.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Washer powers on and runs cycles normally
• ✔ Drum spins, drains, and fills correctly
• ✔ Water supply and inlet valve confirmed OK
• ✔ ONLY problem is leaking from the dispenser area OR detergent/softener not flushing into the drum

❓ Frequently Asked Questions

Q: What does the bellow hose do in my LG washer?
A: It connects the detergent dispenser drawer to the wash tub. During the fill cycle, water flows through the dispenser to pick up detergent and fabric softener, then travels through this hose into the drum. A cracked or disconnected hose means detergent stays in the drawer and water leaks out.

Q: My washer is leaking from the dispenser area. Is this the bellow hose?
A: Yes — a cracked or loose bellow hose is the most common cause of dispenser-area leaks. Inspect the hose for cracks, splits, or loose clamp connections. If the hose feels brittle or you see water staining around the dispenser housing, replace it.

Q: Do I need the hose clamp (4860FR3092C)?
A: It depends on your model. Some LG washers use clamps to secure the bellow hose; others use friction-fit connections. If your old hose had clamps and they're damaged, replace them. Contact us with your model number if you're unsure.
