LG washers are known for their efficiency and advanced features, but occasionally, they may encounter errors that require troubleshooting. One common error that users may come across is Error 03. This error code indicates a problem with the water level or pressure sensor in your LG washer.

Possible Causes of Error 03:

Troubleshooting Steps:

If you encounter Error 03 on your LG washer, follow these steps to troubleshoot and resolve the issue:
