Dishwashers have become essential in our daily lives, making doing the dishes less tiresome and more efficient. However, like any other appliance, they can encounter issues that require troubleshooting. One of these error codes is the LG dishwasher IE error code.
This code usually indicates a problem with the water inlet in the dishwasher. In this article, we’ll explore the possible causes of this error code, how to fix it, and ways to prevent it from showing up on the control panel.
Causes of LG Dishwasher IE Error
What causes this error code? Is it an issue with the drain pump, thermistor, water level, heater, or temperature sensor? Or something related to a heating element, water temperature, or the drain hose outlet? Let’s explore some common causes below:
1. Clogged Water Inlet Filter
A common cause of the LG dishwasher IE error is a clogged water inlet filter. The filter prevents debris, other blockages, and sediments from entering the dishwasher. Still, over time it may become blocked, restricting water flow into the appliance, in other words, becoming a circuit breaker.
Regular use of the dishwasher, combined with minerals and sediments in tap water, can lead to the accumulation of dirt and debris in the filter, causing it to need repairs. If left unattended, a clogged filter can trigger the IE error code and put extra strain on the water inlet valve and other components, shortening their lifespan.
2. Faulty Water Inlet Valve
Another possible cause of the IE error is a faulty water inlet valve. The inlet water valve controls the flow of water into the dishwasher, ensuring a normal water level. It may not allow enough water to enter the appliance if it’s not functioning correctly.
The water inlet valve is an electro-mechanical component. Over time, it can wear out or become damaged due to various factors, such as corrosion, mineral buildup, or electrical issues. A malfunctioning water inlet valve can result in insufficient water flow, triggering dishwasher error codes.
3. Low Water Pressure
Low water pressure in your home plumbing system can also lead to a fault code. The dishwasher requires sufficient water pressure to function correctly, and if the pressure is too low, it may not fill up with enough water.
There could be several reasons for low water pressure, such as a partially closed water supply valve, blocked or frozen water pipe, or issues with your home’s water supply. It’s essential to identify and resolve low water pressure problems to ensure the proper functioning of your dishwasher and prevent IE errors.
4. Kinked or Damaged Water Supply Hose
The water supply hose connects the dishwasher to your home’s water supply. If this hose is kinked, damaged, or leaking, it can cause an IE error by restricting water flow into the dishwasher. Hoses can become kinked due to improper installation or movement of the dishwasher during use.
Additionally, hoses can develop cracks, holes, blockages, or other damage over time, leading to water leakage and reduced water flow or a water inlet error.
How to Fix LG Dishwasher IE Error?
You might consider hitting the power button several times for a reset, but this is not always a solution for dishwasher error codes. Sometimes the solution is different. Here are some solutions to fix the error code:
1. Clean the Water Inlet Filter
To fix a clogged water inlet filter, first deal with the water supply cut-off valve and disconnect the power. Next, locate the water inlet valve (usually at the bottom of the appliance) and remove the filter screen.
Clean it thoroughly with a brush and warm soapy water, then rinse it under running water to remove foreign objects. Once the filter is clean, reinstall it and reconnect the power and water supply. Run a test cycle to ensure the dishwasher fills up properly and the IE error has been resolved.
2. Replace the Water Inlet Valve
If the inlet water valve is faulty, it must be replaced. Disconnect the dishwasher’s power and turn off the water supply. Locate the water inlet valve, which usually is located beneath the kick plate or access panel at the bottom of the dishwasher.
Carefully disconnect the wiring and hoses connected to the valve. Remove and replace the old valve, ensuring it’s correctly placed and aligned. Reconnect the wiring, hoses, power, and water supply, and then run a test cycle to verify that the dishwasher fills up correctly and that the IE error has been resolved.
3. Check and Increase Water Pressure
If low water pressure is the cause of the IE error, you’ll need to determine if it’s an issue with your home’s plumbing system or the dishwasher itself. Check the water pressure at other fixtures in your home. If it’s low, you may need to contact a plumber to resolve the issue.
If the pressure is sufficient elsewhere, ensure the dishwasher’s water supply hose is connected to a high-pressure water source. Additionally, check the water supply valve and make sure it’s fully open. If the problem persists, consider installing a water pressure booster to increase the pressure specifically for your dishwasher.
4. Inspect and Replace the Water Supply Hose
First, turn off the water supply and disconnect the power to fix a kinked, damaged, or leaking water inlet supply hose. Remove the hose from the dishwasher and inspect it for kinks, cracks, or other damage. If the hose is damaged, replace it with a new one.
If it’s kinked, straighten it out and reinstall it, ensuring no sharp bends could restrict the water flow. Once the hose is reconnected, turn on the water supply and power, then run a test cycle to ensure the dishwasher fills up properly and the IE error is resolved.
Preventing LG Dishwasher IE Error Code
Here are some ideas to prevent error codes and keep your dishwasher in top condition:
1. Regular Maintenance and Cleaning
Regular maintenance and cleaning of your dishwasher can help prevent the IE error from occurring. Clean the water inlet filter and check the water supply hose for kinks or damage at least once every six months. Additionally, inspect the water inlet valve for signs of wear or damage and replace it if necessary.
Keeping these components in good condition can minimize the risk of IE error and maintain your dishwasher’s performance.
2. Monitor Water Pressure
Keep an eye on the water pressure in your home to ensure it remains at an adequate level. If you notice a pressure drop, address the issue promptly to prevent the IE error from occurring in your dishwasher.
Regularly check the water supply valve to ensure it’s fully open and functioning correctly. Consider installing a water pressure regulator or booster if your home’s water pressure is consistently too low or fluctuates frequently.
3. Install a Water Pressure Regulator
Consider installing a water pressure regulator if your home’s water pressure is consistently too high or too low. This device can help maintain a consistent water pressure level in your plumbing system, reducing the LG dishwasher IE error risk.
A water pressure regulator can also help protect your dishwasher and other appliances from damage caused by sudden pressure surges or drops.
4. Replace Aging Components
Over time, components such as the water inlet valve and water supply hose can wear out and become less efficient. Replacing these parts before they fail can help prevent the IE error and keep your dishwasher running smoothly.
Regular inspection and timely replacement of worn or damaged components can extend the life of your dishwasher and ensure that it operates efficiently.
