Problem summary
Water leaking from your LG washing machine during or after a cycle is a common fault. The leak may appear under the appliance, from the front, or around the door area. Most leaks come from one of three wear parts: the door seal, the inlet or drain hose, or the drum itself.
Likely causes
Based on repair data, leaks in LG models in this range usually stem from:
Door seal (most common) The rubber seal around the door degrades over time, especially if the machine is used frequently or if detergent residue builds up. A damaged or worn seal lets water escape during the wash cycle.
Hose damage The inlet hose (hot and cold water supply) or drain hose can crack, split, or come loose at the connection points. Age, pressure spikes, or accidental damage during cleaning can cause this.
Drum perforation A hole or crack in the drum itself will leak water continuously throughout the cycle. This is often caused by a foreign object (coin, wire, bone) getting trapped between the drum and the outer tub during spin.
What you can try yourself (DIY)
If you're confident working with appliances, these checks may identify the fault:
Check the door seal - Unplug the machine. - Look inside the rubber seal around the door for visible tears, cracks, or hardening. - Run your finger around the seal to feel for damage. - Check if the seal is seated correctly in its groove.
Inspect the hoses - Unplug the machine and turn off the water supply. n- Follow the inlet hoses from the back of the machine to the wall. Look for splits, cracks, or bulges. - Check the drain hose for kinks, splits, or loose jubilee clips at either end. - Gently flex the hose to check for cracks that only show when pressurised.
Listen and observe during a cycle - If you can safely see where the water emerges, note the exact location—this helps identify which part has failed. - Listen for hissing (suggests a hole under pressure) or dripping (suggests a slow seal leak).
If you find a faulty hose or seal, these are wear parts you may be able to replace if you have basic DIY skills and access to a replacement. However, if the drum is perforated or if you're unsure, proceed to the next section.
Why some faults need an engineer
If the leak comes from inside the machine (not the hoses or door), the drum is likely perforated. Fixing this requires dismantling the appliance to access the inner drum, which involves disconnecting the motor, pump, and various clips. This work is best left to a qualified engineer.
If you've checked the obvious areas and still can't identify the source, or if you're not confident opening the machine, a professional diagnosis will save time and prevent further water damage.
If you're in Northern Ireland, SMC Services can usually book a repair within 2-3 working days.
