Start here
A LG that leaks is nearly always leaking at a joint you can reach. The ranking below is ordered for this brand; establish when the water appears during a cycle first, because that alone points at one of the top three entries.
Symptoms, including the misleading ones
- A trickle from the detergent drawer during the fill — A blocked or overfilled drawer backing up, which is usually detergent rather than a fault.
- Water at the back as soon as the taps are opened — Nothing to do with the cycle: that is a fill hose or a tap connection.
- Water appearing during the wash, at the front — Points at the door seal, the detergent drawer or the filter cap rather than at the plumbing.
- NEAR MISS — the floor is wet only where the machine drains into a sink — Check the sink and the hose position before suspecting the machine at all.
What goes wrong here, in order
- The tub seal or the pump housing — Water that appears from the centre of the machine's underside, or that leaks only when the drum spins, can be coming from the tub seal or from a cracked pump housing. Both are behind panels and neither is an owner repair. This is the one to start with: it explains more of these calls than anything else and it costs nothing to rule out. LG is a major manufacturer with a documented parts catalogue and an established service network, so the question on this brand is usually which part rather than whether a part can be had.
- The drain filter cap — The filter at the bottom front is opened for cleaning and then not seated properly, or its seal is left twisted. It leaks a little on every cycle, always at the front, and it is blamed on the door almost every time. Second on this brand: it takes a moment to check and it explains the leaks that appear at the front bottom.
- The door seal or the boot — On a front-loading machine the flexible boot between the door and the drum catches fibres, coins and grit at its lowest point, and eventually splits or simply stops sealing. It leaks during the wash rather than at fill, and always at the front. Third on this list: it is a real cause but the joints above it are commoner and quicker to check.
- The fill hoses and the tap connections — Two hoses under mains pressure, each with a washer inside a screwed coupling. A perished washer, a coupling cross-threaded at installation, or a hose crushed where the machine was pushed back will weep, and mains pressure turns a weep into a puddle. Next after those: they explain the leaks that appear with the machine switched off, which are the minority here.
What to check first, second, third
- Watch where the first drop lands during a spin — Water arriving at the centre of the underside during spin, with every reachable joint dry, points behind the panel.
- Open the flap at the bottom front and look at the cap and its seal — Damp inside the flap with a dry floor elsewhere identifies it. Check the seal is seated and not twisted.
- Pull the lower fold of the door seal open and look inside it — Grit, coins and a split in the rubber all live at the bottom of that fold, and a tear there leaks on every wash.
The owner checks, step by step
- Reseat the filter cap with its seal clean and straight — Have a tray ready: opening it releases whatever is standing in the pump housing.
Tools: shallow tray, towelsAbout 15 min
- Clean the door seal fold and check the glass and the seal face — Wipe the fold out, remove anything trapped, and look for a split along the lower edge where it is almost always found.
Tools: cloth, torchAbout 15 min
- STOP before removing a panel to trace a leak inside the cabinet — Live terminals sit beside standing water in there. Identifying when the leak happens is the useful end of an owner check.
Before anything comes apart
Safety
Unplug the machine or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Shut both taps before disconnecting a hose, and expect water in the machine even when the drum looks empty: a drain filter opened without a tray under it empties onto the floor.
When this becomes a service call
Call when every reachable joint is dry and water still appears — particularly if it only arrives during the spin, which points inside the cabinet. Stop using the machine and call at once if water is reaching a socket or running under a neighbouring appliance.

What is deliberately not here
Generalized information, written for the class rather than the model. Where a LG family- or model-specific page exists beneath this one, that is the page for your machine. Deliberately absent here: service-manual steps, component part numbers and any specification that differs between families.
