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.
