When your LG dishwasher is working properly, it operates as a fantastic appliance that saves you time and effort in the kitchen. However, any sign of malfunction—like the normal light blinking—can cause frustration and confusion. This article explores the various reasons why this might happen and provides you with insights and solutions to get your dishwasher back to optimal performance.
Understanding Your LG Dishwasher’s Indicators
To effectively troubleshoot the issue of the blinking normal light, it’s crucial to understand the indicators and what they represent. LG dishwashers utilize a variety of lights to convey information about their current operational status.
Normal Light Indicators Explained
The normal light on your LG dishwasher typically indicates that the appliance is in operation or has completed its cycle. This light can blink for several reasons:
- Cycle Completion: The most common reason for the normal light blinking is that the unit has completed its wash cycle and is signaling the user.
- Malfunction or Error Codes: If the blinking persists, it could mean there is an error that needs addressing.
Understanding these indicators will help you identify whether your appliance is performing as expected or if action is needed.
Common Reasons for Blinking Normal Light
When the normal light on your LG dishwasher blinks, several underlying issues might be causing the problem. Below, we will explore these reasons in detail.
1. Cycle Completion
One of the most straightforward explanations for a blinking normal light is that the wash cycle has finished. If this is the case, the blinking might be a gentle reminder to open the door and unload your clean dishes. This is especially common in the following scenarios:
Power Loss During the Cycle
Sometimes, if there’s a temporary power disruption, the dishwasher might not fully complete its cycle. In such cases, it may restart or stop mid-cycle, causing the normal light to blink. If this occurs, simply checking the dishes inside might be sufficient.
How to Confirm Cycle Completion
To confirm that the cycle has completed, follow these steps:
- Open the dishwasher door slightly to see if steam escapes—this indicates that the cycle has been completed.
- Check the status display (if available) for any final cycle indications.
- Listen for the draining sound which generally occurs at the end of a wash cycle.
If there’s nothing wrong, you can safely unload your clean dishes.
2. Error Codes and Malfunctions
If the normal light is blinking without any sign of cycle completion, it may indicate an error or malfunction within the dishwasher. The blinking might correspond to a specific error code that needs troubleshooting.
Common Error Indicators
In LG dishwashers, the blinking light could indicate several error types:
- Water Supply Issues: This could occur due to blocked water inlet filters or issues with the water supply line.
- Drainage Problems: If your dishwasher is unable to drain water properly, it may trigger the blinking light to signal a fault.
- Door Lock Failure: A malfunction in the door lock system can prevent your appliance from starting or completing its cycles, indicated by a blinking normal light.
- Heating Element Failures: If the dishwasher does not reach the correct water temperature, typically due to a faulty heating element, the normal light might blink to indicate this malfunction.
3. Understanding Error Codes
The blinking normal light is often accompanied by other lights flashing in certain sequences. Understanding these patterns is essential to pinpointing the problem.
To identify the specific error code:
- Count the Blinks: Note how many times the normal light blinks in succession. Some models will also have additional lights blinking.
- Consult User Manual: Look up the error code in your dishwasher’s user manual, which will explain what the blinking sequence signifies.
- Contact Customer Support: If you cannot find an explanation, reaching out to LG customer support can provide you with solutions tailored to your specific model.
Troubleshooting Steps for a Blinking Normal Light
When faced with a blinking normal light, it’s essential to follow troubleshooting steps that could rectify the issue without requiring professional assistance.
Step 1: Power Reset
One of the simplest solutions to a blinking normal light is to reset the dishwasher. You can perform a power reset by following these steps:
- Turn off the dishwasher using the power button.
- Unplug the unit from the wall outlet or switch off the circuit breaker that powers the appliance.
- Wait for approximately 5 minutes.
- Plug the unit back in or turn on the circuit breaker.
- Power on the dishwasher and check if the normal light is still blinking.
Dining with different electronic appliances often requires resets to clear temporary glitches, and it works well with dishwashers too.
Step 2: Check Water Supply
If the normal light continues to blink, it’s essential to check the water supply:
- Ensure that the water supply valve is open.
- Inspect the hose for any kinks or blockages.
- Remove and clean the inlet filter to ensure water can flow freely into the dishwasher.
A consistent water supply is crucial for allowing your dishwasher to complete its cycle.
Step 3: Examine Drainage System
Drainage problems might prevent the normal light from stabilizing. To check the drainage system:
- Inspect the drain hose for clogs or bends.
- Remove and clean the filter at the bottom of the dishwasher, as a buildup of residue can impede drainage.
- Ensure the garbage disposal (if connected) is not blocked.
Addressing drainage issues helps in allowing proper operation and cycle completion.
Step 4: Investigate Door Lock Mechanism
If the door isn’t securely locked, the dishwasher won’t operate, and the normal light may blink as a warning. To ensure the door lock mechanism is functioning properly:
- Inspect the door latch for any visible wear or damage.
- Ensure the door seals are clean and intact.
- Replace the door lock if necessary.
Improper lid sealing can trigger safety mechanisms that halt operations and might lead to blinking lights.
Step 5: Inspect Heating Element
If your dishwasher isn’t heating water properly, it’s essential to inspect the heating element:
- Utilize a multimeter to check for continuity in the heating element.
- If the element is faulty, replacing it will often stop the normal light from blinking.
It’s wise to refer to detailed instructions or a professional if you’re unsure.
When to Call for Professional Help
While many troubleshooting steps can resolve a blinking normal light on your LG dishwasher, certain situations may require calling a professional service.
- Persistent Issues: If the light continues to blink despite multiple troubleshooting attempts, there’s likely a deeper issue at play.
- Electrical Errors: Understanding the electrical components can be complex; if you’re unfamiliar or unsure, it’s best to consult with a professional.
- Replacement Parts: If you suspect that certain parts need replacing, having a technician evaluate and replace them will ensure they are installed correctly.
Conclusion
Experiencing a blinking normal light on your LG dishwasher can be frustrating, but understanding its meaning is the first step in addressing the issue. By considering possible reasons—from simple cycle completion to potential malfunctions—you can troubleshoot effectively or know when to seek professional help.
Keeping your LG dishwasher in optimal condition ensures that it serves you well for many years to come. Regular maintenance and awareness of its operational indicators will make all the difference in your kitchen experience. Should you need assistance or more details, don’t hesitate to consult the user manual or reach out to customer service.

What does the normal light blinking indicate on my LG dishwasher?
The normal light blinking on your LG dishwasher generally indicates that the appliance is in operation or going through its wash cycle. It signifies that the machine is performing tasks such as washing, rinsing, or drying, and is functioning as intended. This light is part of the dishwasher’s built-in diagnostic system, which helps users understand the status of the machine.
If the normal light is blinking continuously or in a pattern not described in the user manual, it may require further investigation. Consult your user guide to determine if there are specific error codes associated with the blinking pattern, as these can provide insights into potential issues with the dishwasher.
How do I know if my LG dishwasher is malfunctioning?
If your LG dishwasher’s normal light is blinking alongside other warning lights or error codes, it could indicate a malfunction. Pay attention to any unusual sounds, leaking water, or failure to complete its cycle, as these symptoms often accompany the blinking light. Review the dishwasher’s manual for guidance on interpreting these signs and error codes.
Additionally, perform a quick visual inspection of your dishwasher. Check for obstructions, ensure that the door is closed properly, and verify that nothing is blocking the spray arms. If normal operation does not resume after resolving any visible issues, it may be necessary to contact a professional service technician for further diagnosis and repair.
What should I do if the normal light keeps blinking after a cycle?
If the normal light keeps blinking even after the wash cycle has completed, it may indicate that the dishwasher is stuck in a specific mode or is unable to finish its program due to an error. First, try resetting the dishwasher by turning it off and unplugging it for a few minutes before plugging it back in. This can often resolve temporary glitches.
If the blinking continues after resetting, check for any blockage or issue with the drain line and filters, as clogged systems can result in a cycle not completing. If problems persist, refer to the user guide for troubleshooting tips or seek professional assistance to ensure that there are no underlying issues.
Why is my LG dishwasher not starting while the normal light is blinking?
When your LG dishwasher’s normal light is blinking, yet the machine fails to start, it may indicate that the machine is not receiving power or is experiencing a door latch issue. Ensure that the dishwasher is properly plugged into a working outlet and that there are no blown fuses or tripped circuit breakers in your electrical panel.
If power is confirmed, check if the door is securely closed and latched. The dishwasher will not begin its cycle if the door is ajar or not sealed correctly, which could cause the normal light to blink. If both conditions are satisfied and the issue persists, consult the user manual or contact customer support for advanced troubleshooting steps.
Can I continue using my LG dishwasher with the normal light blinking?
Continuing to use your LG dishwasher with the normal light blinking is generally not advised unless you have verified that the blinking is part of the normal wash cycle. If the light is blinking in a pattern that you suspect indicates an error, it’s best to address the issue before proceeding to avoid potential damage to the appliance.
If the blinking is persistent and not improving after the cycle is finished, stop using the dishwasher to prevent further complications. Investigate the underlying cause, follow any troubleshooting steps outlined in the manual, or seek service assistance if necessary. This approach ensures you maintain the functionality of your dishwasher over the long term.
What maintenance can I do to prevent blinking lights on my LG dishwasher?
Regular maintenance is essential to prevent issues that may lead to blinking lights on your LG dishwasher. Start by routinely cleaning the filter, check the spray arms for blockages, and run a cleaning cycle with dishwasher cleaner. This not only helps improve the machine’s performance but also minimizes the chances of error codes occurring.
Additionally, ensure that the door seals are clean and intact to prevent leaks that could interfere with the dishwasher’s operation. Conducting these small maintenance tasks can significantly contribute to the longevity and reliability of your appliance, reducing the likelihood of encountering blinking light issues in the future.
Where can I find my LG dishwasher’s manual for troubleshooting?
You can find your LG dishwasher’s manual online by visiting the official LG website, where you can locate the appropriate document based on your dishwasher’s model number. Most manuals include troubleshooting sections that outline common blinking light issues and their significances, along with step-by-step guides for resolving them.
If you have the physical manual, refer to the troubleshooting section for detailed instructions on understanding blinking lights and error codes. If you cannot find a solution in the manual, you can also reach out to LG customer service for further assistance. They can provide guidance specific to your situation, ensuring you have the information needed to resolve any problems efficiently.
