Error Code: 1E Difficulty: Moderate
Problem: A problem with the water supply.
How to Fix 1E Error (Step-by-Step)
- Turn off the water supply to the washer. Unplug the washer from the wall outlet for safety.
- Check the water inlet hoses at the back of the machine. Ensure they are not kinked, bent, or crushed.
- Unscrew the hoses from the washer. Inside the connection ports on the washer, you will find small filter screens. Carefully remove these screens with needle-nose pliers.
- Clean the filter screens thoroughly under running water to remove any sediment or debris. Reinstall the clean screens.
- Reconnect the hoses securely, ensuring a tight fit to prevent leaks. Turn the water supply back on fully.
- If the error persists, the water inlet valve may be faulty. Access this part by removing the top panel of the washer. It’s the part the hoses connect to.
- Disconnect the wire harnesses and remove the mounting screws to replace the old valve with a new one.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
LG Washer 1E Checks Before Replacing Parts
- Confirm both water faucets are fully open and that hot and cold water flow strongly from the hoses into a bucket.
- Clean the inlet screens at the washer connections and inspect the hoses for kinks, crushed sections, frozen lines, or flood-safe shutoff behavior.
- Run a fill test on warm, hot, and cold settings; a failure on only one side can point toward supply or valve-side issues.
- Inspect the water inlet valve connectors and the pressure-sensor hose before replacing parts.
- Use the complete LG washer model number from the door or rear tag before matching any inlet valve, sensor, hose, or control-board category.
