LG dishwasher ie or 1e error

Every piece of technology, regardless of its sophistication or price, is prone to occasional hitches. This is also true for household appliances like LG dishwashers, which may display certain error codes from time to time. One such code is the ‘IE’ or ‘1E’ error, which many LG dishwasher owners have encountered.

A Look at LG’s Error Code System

LG employs an error code system in their appliances, including dishwashers, to alert users about potential issues. These codes consist of an alphabet or numeric character combination and display on the appliance’s screen when a problem occurs. Each code signifies a different issue, allowing users to identify the trouble area swiftly.

The ‘IE’ or ‘1E’ error code typically appears when there’s a problem related to water intake or water supply in your dishwasher. However, before you panic, it’s crucial to understand what this code implies, how it occurs, and most importantly, how to resolve it.

Understanding the ‘IE’ or ‘1E’ Error Code

The ‘IE’ or ‘1E’ error code on an LG dishwasher points to a water inlet issue. It essentially means that the dishwasher is unable to draw in the right amount of water required for a wash cycle. This could occur for a variety of reasons, including problems with water pressure, blockages, or issues with the water inlet valve.

Before jumping to conclusions and assuming the worst, it’s best to check the basics first. Verify that the water supply is turned on and functioning correctly. Examine the water supply hose for kinks or damage that might impede water flow. It’s also worthwhile to inspect the filter and the inlet valve for any clogs or blockages.

Troubleshooting the Error

The most straightforward step in rectifying the ‘IE’ or ‘1E’ error is to ensure the water supply is adequate and that there are no visible issues with the hose or inlet. If you can’t find any issues here, or if the problem persists, you may need to delve a bit deeper.

  1. Check Water Pressure: A common culprit behind the ‘IE’ or ‘1E’ error is low water pressure. You can test the water pressure by turning on the faucet that feeds your dishwasher. If the pressure seems low, you might need to address this with your water supplier or check for potential issues in your home’s plumbing.
  2. Inspect the Inlet Valve: If the water pressure seems fine, the next step is to examine the water inlet valve. This valve, responsible for controlling the water supply to your dishwasher, could malfunction or become clogged. If you suspect this is the issue, it’s recommended to hire a professional to inspect and possibly replace the valve.
  3. Look for Clogs or Blockages: Sometimes, the dishwasher’s filter or sump might become clogged, leading to the ‘IE’ or ‘1E’ error. If the filter is dirty, give it a thorough cleaning. If there’s a blockage in the sump, you might need professional help to remove it.
  4. Assess the Float Assembly: The float assembly is an important component that stops the dishwasher from overfilling. If it’s stuck or malfunctioning, the dishwasher may mistakenly believe it’s not getting enough water, triggering the ‘IE’ or ‘1E’ error. Inspect the float assembly and ensure it’s functioning correctly.


While the ‘IE’ or ‘1E’ error in an LG dishwasher can be frustrating, it’s usually a signal of an issue that can be rectified. It’s a mechanism that helps prevent bigger problems by alerting you to take action early. By understanding what this code means and learning how to troubleshoot it, you can restore your dishwasher to its normal functioning in most cases. Remember, it’s always best to consult with a professional if you’re unsure about any of the steps involved or if the problem persists after your troubleshooting efforts.
