The "Inlet Error" on your LG dishwasher, often displayed as an IE error code, signals a critical issue: your dishwasher is not filling with water. This means that your dishes won't get washed effectively, as the appliance isn't receiving the necessary water supply for its cycles.
Understanding the IE Error on Your LG Dishwasher
An IE error points directly to a problem with the water intake system. There are several potential culprits preventing water from reaching the wash tub. Understanding these common causes can help you diagnose and resolve the issue efficiently.
Common Causes of an LG Dishwasher IE Error
To help you troubleshoot, here's a breakdown of the most frequent reasons your LG dishwasher might display an IE error:
- Closed or Partially Closed Water Supply Valve:
- Insight: This is one of the simplest yet most overlooked issues. Your dishwasher needs a fully open water supply to function correctly.
- Solution: Locate the water supply cut-off valve for your dishwasher (it's usually under the kitchen sink or behind the dishwasher itself). Ensure it is fully open. A valve that is even partially closed can severely restrict water flow, leading to an error.
- Kinked or Clogged Inlet Water Hose:
- Insight: The flexible hose that connects your dishwasher to the household water supply can easily become kinked, especially if the dishwasher has been recently moved or installed. Over time, mineral deposits or sediment can also build up inside the hose, creating a blockage.
- Solution: Carefully pull the dishwasher out a few inches (if possible and safe) and inspect the water inlet hose for any visible kinks or sharp bends. Straighten them if found. If you suspect a clog, you might need to disconnect the hose (after turning off the water supply!) and check for debris.
- Malfunctioning Water Inlet Valve:
- Insight: Also known as a solenoid valve, this component is an electrical valve that opens to allow water into the dishwasher when signaled by the control board. If it fails electrically or mechanically, it won't open, or it might not open fully, preventing water from entering.
- Solution: A faulty inlet valve typically requires replacement. Signs of failure include no water entering the dishwasher at all, or a very slow, dribbling fill. While some advanced DIYers might attempt to test it with a multimeter, for most users, this issue is best addressed by a service technician.
- Low Household Water Pressure:
- Insight: If your home's overall water pressure is low, your dishwasher may not receive enough water to trigger its fill sensors within the allotted time, resulting in an IE error.
- Solution: Check the water pressure at other faucets in your home, particularly the hot water tap. If they all have low pressure, the issue might be with your home's main water supply. Contact your water utility provider or a plumber if this appears to be the case.
- Clogged Inlet Valve Screen/Filter:
- Insight: The water inlet valve usually has a small screen or filter designed to catch sediment and debris before it enters the sensitive internal components of the dishwasher. This screen can become clogged over time, severely restricting water flow.
- Solution: After turning off the water supply to the dishwasher and disconnecting the inlet hose from the valve, you can usually see and carefully clean this small screen. Use a soft brush or rinse it under a faucet to remove any accumulated debris.
- Faulty Float Switch:
- Insight: The float switch is a safety mechanism located at the bottom of the dishwasher tub. It rises with the water level and signals the control board to stop filling when the water reaches the correct height. If it gets stuck in the "up" position, the dishwasher thinks it's already full and won't initiate a fill cycle.
- Solution: Manually press down on the float (it's usually a small plastic cap or post inside the tub). Ensure it moves freely up and down without obstruction. Clean any debris or food particles that might be preventing its free movement.
Step-by-Step Troubleshooting for an LG Dishwasher IE Error
Before calling for service, try these practical troubleshooting steps:
- Verify Water Supply:
- Locate the water supply shut-off valve for your dishwasher (often under the kitchen sink).
- Ensure it is fully turned to the open position.
- Test the hot water faucet at your kitchen sink to ensure you have adequate hot water pressure there.
- Inspect Inlet Hose:
- Gently pull the dishwasher out from the wall a few inches (if safe and possible).
- Check for any visible kinks, twists, or sharp bends in the water inlet hose. Straighten them carefully.
- Ensure the hose isn't pinched against the wall, cabinetry, or other appliances.
- Clean Inlet Filter (Advanced Step):
- Important: Turn off the main water supply to the dishwasher before proceeding!
- Disconnect the water inlet hose from the back of the dishwasher.
- Inspect the small screen or filter located at the point where the hose connects to the dishwasher's inlet valve.
- Carefully clean any debris with a soft brush or by rinsing it under running water.
- Reconnect the hose securely, ensuring no leaks.
- Check Float Switch:
- Open the dishwasher door and look for the small plastic float (usually a cap or post near the front bottom, inside the tub).
- Gently push it down with your finger to ensure it moves freely and isn't stuck in the raised position.
- Reset Your Dishwasher:
- Go to your home's electrical service panel and turn off the circuit breaker that powers the dishwasher for a period of 5-10 minutes.
- Turn the breaker back on. This can sometimes reset the control board and clear minor electronic glitches.
- Run a Test Cycle:
- After performing these checks, close the dishwasher door and start a short wash cycle to see if the IE error has cleared and if the dishwasher begins to fill with water.
| Potential Cause | Quick Solution | When to Call a Professional |
|---|---|---|
| Water Supply Valve Closed | Fully open the valve. | If the valve is broken, seized, or difficult to access safely. |
| Kinked/Clogged Inlet Hose | Straighten kinks; inspect for internal blockages. | If the hose is damaged, cracked, or needs replacement. |
| Malfunctioning Inlet Valve | - | Immediately, as this is a component that requires replacement. |
| Low Household Water Pressure | Check other faucets; contact water utility or a plumber. | If the issue persists across your home's entire plumbing system. |
| Clogged Inlet Valve Screen | Clean the screen after safely turning off water supply. | If cleaning doesn't resolve the issue or the valve appears damaged. |
| Stuck Float Switch | Ensure it moves freely; clean around it for obstructions. | If the switch is physically broken, corroded, or doesn't respond. |
