LG Washing Machine Error Code E1
On older LG models, E1 reports water detected in the sump or base of the machine. Treat any leak code seriously: find the water first.
Common causes
- Split or loose internal hose
- Leaking pump or tub seal
- Overflowing from excessive suds
What to check, in order
- Switch off the power and close the taps, then look for water under the machine.
- Check accessible hose connections for drips.
- Internal leaks need a technician to open the cabinet safely.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, taps opened. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the machine back in and restore the water supply.
- Run a short rinse and spin, or the shortest wash programme, and watch the stage where the code appeared before (filling, washing, draining or spinning).
- If the cycle finishes with no code, the fault is cleared. If the code returns at the same stage, write down the code and that stage before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E1, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Parts that may be involved

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
