If your older LG Washer is showing error code 1E, the machine has detected a water level sensor fault or a water fill failure. Error 1E on older LG Washer models is equivalent to the IE error on modern machines — both indicate that the washer cannot confirm the correct water level in the drum. Here is how to resolve LG Washer error 1E.

⚡ Quick Fix – Top 3 Steps

1. Check that the water supply taps are fully open. Error 1E most commonly appears when the LG Washer cannot fill with water in the expected time. Ensure both the hot and cold supply taps at the back of the machine are turned fully anti-clockwise (open). Low water pressure or a partially closed tap is the most frequent and easily resolved cause of 1E.
2. Clean the inlet filter screens. The water inlet hoses connect to inlet valves at the back of the washer. Inside each inlet valve fitting is a small mesh filter screen that can become clogged with limescale, grit, or debris from the water supply. Turn off the water supply, unscrew the inlet hoses, and use a small brush or toothpick to remove any deposits from the filter screens. Reattach and turn the water back on.
3. Check the pressure sensor hose. Error 1E can also be caused by the water level pressure sensor (pressure switch) not correctly detecting the fill level. Inspect the thin hose that runs from the pressure sensor to the tub and check for kinks, blockages, or disconnection. Clearing a blocked hose often resolves 1E when water supply is confirmed good.

What Does LG Washer Error 1E Mean?

Error 1E appears on older LG Washer models and has the same meaning as error IE on modern LG Washers. It is a water inlet or water level sensor error — the machine could not fill to the required level within the allowed time. On some displays, the digit “1” can be mistaken for the letter “I”, which is why this error appears as both 1E and IE depending on the model’s display type.

Common Causes of LG Washer Error 1E

• Water supply taps closed or partially closed
• Kinked inlet hoses
• Blocked inlet filter screens
• Low water pressure
• Faulty or blocked pressure sensor hose
• Failed water inlet valve (solenoid)
