Understanding The Issue: Flashing Lights On Lg Dishwasher

When it comes to your LG dishwasher, flashing lights can potentially indicate an underlying issue that needs to be addressed. These blinking lights serve as indicators, communicating that something is not functioning correctly with your dishwasher. By understanding the significance of these flashing lights and the possible causes behind them, you can effectively troubleshoot and resolve the problem. In this section, we will delve deeper into the subject, shedding light on the reasons why your LG dishwasher may have blinking lights.

Significance Of Blinking Lights On Lg Dishwasher

The blinking lights on your LG dishwasher play a vital role in alerting you to specific problems or errors that require attention. Each blinking light signifies a distinct issue, helping you identify the underlying cause quickly. It is essential to pay close attention to these lights, as they can help pinpoint the problem, ensuring prompt resolution.

Possible Causes Of The Issue

There are several potential causes for the blinking lights on your LG dishwasher. Understanding these causes can assist you in troubleshooting and addressing the issue effectively. Here are some common factors behind flashing lights on LG dishwashers:

• Micro switch malfunction: One possible cause is a problem with the micro switch inside the door latch assembly. A faulty micro switch can lead to lights blinking on the control panel. Testing the switch for continuity using a multimeter can help confirm if it is at fault. If there is no continuity, it may be necessary to replace either the switch itself or the entire latch assembly.
• Low rinse aid level: In some cases, a blinking “snowflake” light indicates a low rinse aid level. If this light is blinking, it means that the rinse aid needs to be refilled. Refilling the rinse aid can help resolve this issue.
• Control panel malfunction: Another possible cause of blinking lights on the LG dishwasher is a faulty touchpad or control panel. If none of the above issues are present and the lights continue to blink, it is recommended to consider the touchpad or control panel as a potential culprit. In such cases, it may be necessary to replace the faulty component.
• Moisture damage: Moisture entering the control panel can also lead to blinking lights on an LG dishwasher. If the lights blink or flash, and the buttons fail to work, it could indicate moisture damage. In such situations, thoroughly drying the control panel and ensuring it is properly sealed can help resolve the issue.
• Other potential causes: Additionally, low water pressure, dirty filters, or a malfunctioning pump can trigger blinking lights on an LG dishwasher. Checking these components and addressing any issues with them is essential for resolving the problem.

By considering these potential causes and systematically troubleshooting the issue, you can identify and rectify the problem causing the blinking lights on your LG dishwasher. Remember to follow the appropriate troubleshooting steps as outlined in your user manual or seek assistance from a professional if needed.

Testing The Micro Switch In The Door Latch Assembly

A dishwasher’s lights flashing or blinking could indicate a problem with a micro switch inside the door latch assembly. The micro switch is a crucial component that detects the position of the dishwasher door. When the door is closed, the micro switch sends a signal to the control panel to start the dishwasher cycle. If the micro switch is faulty or not functioning properly, it can cause the lights to blink and the dishwasher to malfunction.

Importance Of The Micro Switch In The Door Latch Assembly

The micro switch in the door latch assembly plays a vital role in ensuring the proper functioning of your LG dishwasher. It acts as a safety mechanism, preventing the dishwasher from starting when the door is open. It also signals the control panel to start the cycle once the door is securely closed. If the micro switch is not working correctly, the dishwasher may not start, or the lights may continuously blink.

Using A Multimeter To Test The Switch For Continuity

To determine if the micro switch in your LG dishwasher’s door latch assembly is faulty, you can use a multimeter to test for continuity. Here’s how:

• Disconnect the dishwasher from the power source to ensure safety.
• Locate the door latch assembly, typically located on the top edge of the dishwasher door.
• Remove the screws holding the control panel in place, allowing access to the micro switch.
• Set your multimeter to the continuity or resistance mode.
• Place one probe on the COM (common) terminal of the micro switch and the other probe on the NO (normally open) terminal.
• If the multimeter shows continuity or a low resistance reading, the micro switch is functioning correctly. However, if there is no continuity or a high resistance reading, the micro switch needs to be replaced.

Steps To Replace The Micro Switch Or The Entire Latch Assembly If Necessary

If the micro switch is found to be faulty, you can replace either the micro switch itself or the entire latch assembly, depending on the availability of parts and the complexity of the repair. Follow these steps:

• Ensure the dishwasher is disconnected from the power source.
• Remove the screws holding the control panel in place, giving you access to the micro switch and latch assembly.
• Disconnect the wires connected to the micro switch.
• If replacing the entire latch assembly, remove the screws securing it in place.
• Install the new micro switch or latch assembly in the reverse order, ensuring it is properly aligned and secured.
• Reconnect the wires to the micro switch if necessary.
• Reattach the control panel and secure it with the screws.
• Plug the dishwasher back into the power source.
• Test the dishwasher to ensure the lights are no longer blinking and the micro switch is functioning correctly.

By testing the micro switch in the door latch assembly using a multimeter and replacing it if necessary, you can resolve the issue of blinking lights on your LG dishwasher. Remember to always prioritize safety and consult a professional if you are unsure about any step of the process.

Low Rinse Aid And The “snowflake” Light Blinking

If you see the “Snowflake” light blinking on your LG dishwasher, it means that the rinse aid is low and needs to be refilled. To resolve this issue, refer to the user manual for instructions on how to refill the rinse aid.

Understanding The Indication Of The “snowflake” Light Blinking

If you’re experiencing a blinking “snowflake” light on your LG dishwasher, it is indicating that the rinse aid is low and needs to be refilled. The rinse aid plays a crucial role in ensuring that your dishes come out clean and spot-free. When it is low, the dishwasher alerts you with the blinking snowflake light. It’s essential to understand this indication, as addressing the issue promptly will ensure optimal performance and efficiency of your dishwasher.

Refilling The Rinse Aid To Resolve The Issue

Thankfully, resolving the low rinse aid issue is a simple task that can be done at home. Follow these steps to refill the rinse aid:

• Locate the rinse aid dispenser on your LG dishwasher. It is generally located near the detergent dispenser.
• Twist the rinse aid cap counterclockwise to open it. The cap may have a lock symbol to indicate the direction.
• Pour the rinse aid into the dispenser, ensuring not to overfill it. Most rinse aid dispensers have a maximum fill line. Refer to your dishwasher’s user manual for specific instructions.
• Close the rinse aid cap by twisting it clockwise until it is securely closed.

Once you have refilled the rinse aid, the blinking snowflake light should stop and your dishwasher will be ready to operate with optimal performance. Additionally, make sure to regularly check the rinse aid level and refill it as necessary to avoid future issues and maintain the efficiency of your LG dishwasher.

Random Flickering Lights And Irregular Noises

If you have an LG dishwasher with blinking lights, it could be a sign of a problem with the micro switch inside the door latch assembly. You can use a multimeter to test the switch for continuity and replace it if necessary.

Avoid a costly repair and try troubleshooting it yourself.
