What IE means (lg ie error)
An lg ie error on an LG dishwasher means it is not filling with water correctly — the control does not see the expected water level in time. It usually points to the supply, the inlet valve, or the float rather than a major fault, and it stops the cycle so the dishwasher does not run dry.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your LG Dishwasher. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- The display shows “IE”
- The dishwasher does not fill or fills slowly
- The cycle pauses early waiting for water
- You hear the valve trying without water entering
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct LG parts.
- Supply valve partly closed — the water shutoff is not fully open
- Clogged inlet screen — debris blocks the valve inlet
- Kinked fill hose — the supply hose is pinched
- Inlet valve or float fault — the valve will not open or the float sticks
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a heat-pump compressor are involved, and hand the rest to a qualified technician.
- Confirm the water supply shutoff under the sink is fully open.
- Check the fill hose is not kinked or crushed behind the dishwasher.
- Make sure the float inside the tub moves freely and is not stuck up.
- If it still will not fill, leave it for service to test the inlet valve.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the water inlet valve, inlet screen, float switch, and fill hose. The correct part for your LG Dishwasher is matched from the model and serial number, and genuine LG components are fitted rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
A persistent IE with good supply needs a technician to test the inlet valve and float switch. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your LG Dishwasher. Keep filters, vents, and the condenser or exhaust path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the LG maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in or laundry installation done to LG specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily.
