LG Dishwasher IE Error Code — What It Means
The IE error code on your LG dishwasher signals that the machine did not reach the required water level within the expected fill time, usually within 30 seconds to 10 minutes depending on the model. LG describes this as insufficient water or no water fill. The dishwasher is detecting low or absent water intake, not a drain problem or generic electronic fault.
Common Causes
- House water supply valve closed or only partially open The under-sink shutoff valve may be turned off, partially closed, or restricted, preventing adequate water from reaching the dishwasher.
- Low household water pressure LG requires household water pressure above 20 PSI for proper operation, and anything below that can trigger the IE code.
- Kinked, pinched, bent, or damaged inlet hose The inlet hose can be crushed behind the unit, kinked at a tight bend, or frozen in cold conditions, blocking water flow.
- Clogged inlet filter or inlet screen Sediment and debris accumulate on the inlet screen at the water connection or inlet valve, restricting flow into the dishwasher.
- Faulty water inlet valve The inlet valve solenoid may fail to open or pass enough water even when supply pressure and screens are correct.
Step-by-Step Fix
- Power down safely. Unplug the dishwasher or switch off the circuit breaker before beginning any inspection or repair work.
- Check the water supply at the source. Confirm the under-sink shutoff valve is fully open and that nearby faucets have normal flow to rule out a house-supply issue.
- Inspect the inlet hose path. Trace the hose from the valve to the dishwasher, looking for kinks, pinches, bends, crushing, or freezing, and straighten or replace the hose if damaged.
- Remove and clean the inlet screen. Disconnect the water supply line at the dishwasher and remove the inlet screen or screened elbow, then rinse away any sediment or debris.
- Test the inlet valve. If supply pressure is good and screens are clean but the dishwasher still will not fill, the water inlet valve is the likely failed component and should be replaced.
- Reassemble and restore power. Reconnect all fittings securely, turn the water back on, restore electrical power, and run a fill test cycle to confirm normal water intake and no return of the IE code.
Parts Often Needed
| Part | Notes |
|---|---|
| LG dishwasher water inlet valve | Amazon | Primary replaceable part when supply, hose, and screens are verified good but fill remains slow or absent. |
| Dishwasher inlet hose | Amazon | Replace if kinked, pinched, torn, frozen, or otherwise no longer serviceable. |
| Inlet screen or filter | Amazon | Replace if the screen is physically damaged or cannot be cleaned adequately. |
When to Call a Pro
If you have verified the water supply is fully open, the hose is clear, and the inlet screen is clean but the IE code persists, the inlet valve itself has likely failed and will need replacement. A qualified appliance technician can safely test the valve electrically, confirm proper installation of a new valve, and check for less common issues such as damaged wiring harnesses or control-board faults. Call a pro if you are not comfortable working with water connections under pressure or if the error returns after you have completed all basic checks.
