LG dishwashers are known for their innovative features and reliable performance, but like any appliance, they may occasionally experience technical issues. If your LG dishwasher is not starting, showing error codes, or failing to complete cycles, a reset can often resolve the problem. Resetting the dishwasher can clear minor software glitches, restore normal operation, and eliminate error messages that appear due to temporary malfunctions.
Understanding how to reset an LG dishwasher properly is crucial for troubleshooting common issues. This guide will explain the different types of resets, when they should be used, and what to do if resetting does not resolve the problem.
When Should You Reset an LG Dishwasher?
A reset is often the quickest way to restore functionality when an LG dishwasher experiences operational errors. While resetting the appliance can help resolve minor technical problems, it is not a universal fix for mechanical failures or damaged components. However, there are several situations where performing a reset is recommended.
If the dishwasher displays an error code, a reset may clear the message if it was triggered by a temporary issue such as a power surge or an unresponsive sensor. In some cases, dishwashers stop mid-cycle or fail to start properly. Resetting the appliance allows the internal system to reboot, potentially resolving these issues. Electrical disruptions, such as sudden power outages, can cause malfunctions in the control panel. A reset can restore communication between internal components and ensure the dishwasher resumes normal operation.
Before performing a reset, it is helpful to check for common problems, such as ensuring the dishwasher door is fully closed, verifying that the power supply is stable, and confirming that there are no visible blockages in the drain system.
How to Reset an LG Dishwasher
Basic Reset Method
A soft reset is the simplest way to restart an LG dishwasher when it becomes unresponsive. To perform a basic reset, begin by turning off the dishwasher using the Power button. If the dishwasher is not responding, unplugging it from the power outlet can help. For models that are hardwired, switching off the circuit breaker that supplies power to the appliance will achieve the same effect.
Once the dishwasher is powered down, waiting for approximately 10-15 minutes allows any remaining electrical charge to dissipate from the control board. After this time, plugging the dishwasher back in and turning it on will allow the system to reboot. Running a short wash cycle can confirm whether the reset was successful.
Factory Reset for Persistent Issues
If the basic reset does not resolve the issue, performing a factory reset can restore the dishwasher to its original settings. This is particularly useful when the control panel is malfunctioning or when repeated error codes appear even after troubleshooting.
To perform a factory reset, turn off the dishwasher and disconnect the power source. Press and hold the Start or Cancel button for at least five seconds before restoring power. This action clears stored memory from the control board, allowing the dishwasher to reset to its default state. After reconnecting the power, selecting a normal wash cycle can confirm whether the issue has been resolved.
For dishwashers with a Control Lock feature, ensuring that the lock is disabled before performing a reset is essential. If the buttons remain unresponsive, holding the Dual Zone and Energy Saver buttons together for three seconds can sometimes deactivate the lock.
Troubleshooting Common LG Dishwasher Problems After a Reset
Error Codes Persisting After Reset
If an error code remains on the display after a reset, it may indicate a hardware issue that requires further troubleshooting. Checking the LG dishwasher manual for specific error code meanings can help determine the next steps.
Dishwasher Not Draining Properly
A clogged drain hose or a blocked filter may cause drainage problems even after resetting the dishwasher. Checking for obstructions in the filter and ensuring that the garbage disposal knockout plug has been removed can help resolve this issue.
Dishwasher Won’t Start After Resetting
If the dishwasher remains unresponsive, checking the door latch and ensuring the unit is receiving power is essential. In some cases, a tripped circuit breaker may prevent the dishwasher from powering on.
For LG dishwashers connected to a smart home system, verifying that Wi-Fi settings are correctly configured can also be beneficial. Some models require re-establishing a connection after a reset, which can be done through the LG ThinQ app.
How to Prevent Future Dishwasher Issues
Regular maintenance and proper use can help reduce the need for frequent resets. Keeping the dishwasher’s filter clean prevents blockages and ensures efficient water drainage. Additionally, using the correct detergent and rinse aid minimizes residue buildup inside the dishwasher.
Running hot water in the sink before starting a wash cycle helps improve cleaning efficiency by ensuring the dishwasher starts with the optimal water temperature. Periodically inspecting the spray arms for debris and removing any obstructions ensures that water is evenly distributed throughout the dishwasher.
For homeowners in areas with hard water, using a dishwasher cleaner specifically designed to remove mineral deposits can prevent scaling and buildup on internal components. Keeping the dishwasher door slightly open after each cycle allows moisture to escape, reducing the risk of mold growth inside the appliance.
When problems persist despite routine maintenance and resetting, seeking professional appliance repair services may be necessary. A trained technician can diagnose underlying electrical or mechanical issues that a reset alone cannot fix.
Conclusion
Resetting an LG dishwasher is often an effective way to resolve minor technical issues, clear error codes, and restore normal operation. Whether performing a soft reset or a factory reset, understanding the correct steps ensures that the dishwasher functions efficiently.
However, if problems persist despite resetting and troubleshooting, professional assistance may be required. For expert LG dishwasher repair services in Northeast Ohio, contact My Appliance Guy to schedule a service appointment and ensure your dishwasher operates at peak performance.
