Safety first
Step-by-step fix
- 1
Step 1
Check the water taps
Turn both water taps connected to the machine fully ON (clockwise to tighten, anti-clockwise to open — depending on your tap type).
- 2
Step 2
Straighten the inlet hose
Check the full length of the inlet hose for any kinks or crushing behind the machine.

Step 3
Clean the inlet filter
Using pliers, unscrew the inlet hose from the machine. Pull out the mesh filter inside the inlet port. Rinse under running water — descale with vinegar if calcium build-up is visible.

Step 4
Verify water pressure
LG front-loaders need 0.3–10 bar pressure. If your building has low pressure during peak hours, this code will appear intermittently.
When to call a technician
- • IE persists after tap check, hose replacement, and filter cleaning
- • Inlet valve on the back of the machine makes a clicking but no water flows (faulty solenoid valve)
