LG Dishwasher Touchpad Not Working

Is your LG dishwasher touchpad failing to respond, leaving you with a non-functional appliance? This issue can be frustrating, but before resorting to costly repairs or replacements, it’s wise to diagnose the problem and explore potential solutions. In this guide, we’ll delve into the possible causes and steps to troubleshoot an unresponsive LG dishwasher touchpad.

1. Power Supply Check


LG dishwashers often come equipped with a child lock feature to prevent unintentional use or tampering. If the touchpad is unresponsive, it might be because the child lock is activated. To deactivate it:

  • Locate the child lock button on the touchpad. It’s usually represented by a padlock icon.
  • Press and hold this button for a few seconds until you hear a beep or see a light indicator turn off.
  • Try using the touchpad again.

3. Keypad Lock Feature

Some LG dishwashers also have a keypad lock feature that can accidentally be engaged. To unlock the keypad:

  • Locate the keypad lock button (often labeled as “Lock” or “Control Lock”) on the touchpad.
  • Press and hold this button for a few seconds until the lock indicator turns off.
  • Test the touchpad to see if it’s working.

4. Restart the Dishwasher

Like many electronic devices, a simple reboot can resolve minor glitches:

  • Unplug the dishwasher or turn off its circuit breaker for about 5 minutes.
  • Plug it back in or turn the circuit breaker back on.
  • Attempt to use the touchpad again.

5. Inspect for Physical Damage

Examine the touchpad and surrounding areas for any physical damage, like cracks or signs of water intrusion. If you notice any issues, contact LG customer support or a technician for further assistance.

6. Check for Error Codes

LG dishwashers often display error codes when they encounter issues. These codes can help diagnose the problem. Consult your dishwasher’s manual for a list of error codes and their meanings. If an error code is displayed, note it down and refer to the manual or LG’s customer support for guidance on how to address it.

7. Software Update

Sometimes, touchpad issues can be related to software problems. Check if LG has released any firmware or software updates for your dishwasher model. Updating the software might resolve the problem.

8. Professional Assistance

If none of the above steps resolve the issue, it’s time to seek professional assistance. Contact LG customer support or a qualified appliance repair technician to diagnose and fix the touchpad problem. They can assess whether there’s a faulty touchpad or a deeper electrical issue within the dishwasher.

9. Conduct a Hard Reset

Performing a hard reset can clear any residual electronic glitches. To do this:

  • Unplug the dishwasher or turn off its circuit breaker.
  • Wait for approximately 10-15 minutes to ensure all capacitors discharge.
  • Plug the dishwasher back in or turn on the circuit breaker.
  • Try using the touchpad once it’s powered up.

10. Inspect the Touchpad Connections

Over time, the internal connections of the touchpad can become loose or corroded, leading to responsiveness issues. You may need to disassemble the dishwasher’s control panel carefully to inspect these connections. However, this should only be attempted by those comfortable with appliance repair. If you’re not experienced, it’s safer to call a technician.

11. Test Other Dishwasher Functions

Check if other functions of the dishwasher, such as the lights, display, or sound indicators, are working correctly. If these functions are also malfunctioning, it could indicate a broader electrical problem. This information can be helpful when discussing the issue with a technician.

12. Environmental Factors

Consider environmental factors that might affect the touchpad. Excessive moisture, humidity, or extreme temperatures can lead to touchpad issues. Ensure the dishwasher is installed in a dry and temperature-controlled area. Also, keep the touchpad clean and dry to prevent any interference with its operation.

13. Warranty and LG Customer Support

If your LG dishwasher is still under warranty, be sure to check the terms and conditions. Touchpad issues, if not caused by user error or external factors, may be covered by the warranty. Contact LG’s customer support and inquire about warranty service or repair options.

14. Replacement Parts

If the technician determines that the touchpad is faulty and needs replacement, ensure that genuine LG replacement parts are used. Generic or third-party parts may not function correctly and could void any remaining warranty.

15. Consider Upgrading

If your LG dishwasher is significantly older and the touchpad issue proves expensive to fix, it might be worth considering an upgrade to a newer model. Newer dishwashers often come with improved technology, energy efficiency, and features that can make your life easier.
