LG Washer Error Code 1

Error code 1 on an LG washer is a water inlet error, meaning the machine failed to reach the correct water level within the allowed time. Specifically, the pressure sensor frequency target of 246 Hz was not achieved within 8 minutes of water supply starting, or the preset water level was not reached within 25 minutes. The washer stops the cycle to prevent running without adequate water.

The washer will not continue the cycle while error code 1 is active, so there is no immediate safety risk. However, you should not attempt to bypass the error or force the machine to run without resolving the underlying fill issue, as running the motor and pump without adequate water can cause component damage over time.

If the fix involves only cleaning clogged inlet screens or adjusting the water supply tap, there is no parts cost involved. If the water inlet valve needs replacement, parts and labor typically range from around 80 to 200 dollars depending on the specific model and service rates in your area. A faulty pressure sensor is a less common repair and costs are generally in a similar range.

Start by checking that both water supply taps behind the machine are fully open and that your home has adequate water pressure. Inspect the inlet hoses for kinks and check the small filter screens at the valve connection points for debris, cleaning them if clogged. If those steps do not resolve the issue, the water inlet valve or pressure sensor may need to be tested and potentially replaced.

Resetting the washer by unplugging it for a few minutes may clear the error temporarily, but the code will return if the underlying cause is not corrected. A reset is useful for ruling out a one-time sensor glitch, but persistent error code 1 requires actual diagnosis and repair of the water supply or related components.
