Hold the phone microphone to the washer speaker and press Smart Diagnosis - the app decodes the diagnostic sounds. LG inlet valve screens are located inside the valve assembly at the back of the washer. LG uses dual-solenoid valves (hot and cold) - if one solenoid fails, the washer fills with only hot or only cold water, which may appear as not filling if the failed solenoid's valve is the only one open at the wall.
