LG Washer Error Code Ed

The Ed code on an LG washer signals an abnormal water temperature error that occurs when water entering the drum during a Delicate or Wool cycle is 50 degrees Celsius or higher. It can also trigger when the water level pressure sensor produces an abnormal frequency of 24.5 kHz. In both cases, the washer automatically drains and runs a forced 2-minute drain to protect fabrics and the machine. The cycle will not proceed until the issue is resolved.

The washer intentionally stops and drains when it displays the Ed code, so it will not complete the cycle on its own. Running Delicate or Wool cycles repeatedly without resolving the cause risks potential fabric damage if the protection system were to fail. It is safe to use other cycles that do not trigger the temperature threshold while you diagnose the issue, but the root cause should be addressed before using heat-sensitive fabric cycles again.

If the fix is simply reconnecting reversed hoses, there is no parts cost involved. Replacing a faulty water inlet valve typically ranges from $50 to $150 for parts, while a thermistor or pressure sensor replacement can range from $20 to $80 in parts, with labor costs varying by region and service provider. Diagnosis by a qualified technician is recommended if the simple checks do not resolve the issue.

Powering the washer off using the power switch is the first recommended step and can clear the Ed code if the triggering condition was temporary, such as a brief spike in hot water supply temperature. However, if the underlying cause persists, such as reversed hoses, a faulty valve, or a failed sensor, the code will return on the next Delicate or Wool cycle. Clearing the code without addressing the root cause is only a short-term measure.

Start by turning the machine off and checking that the hot and cold water supply hoses are connected to the correct inlets on the back of the washer. If the hoses are correct, check whether your household hot water supply is crossing into the cold line. If plumbing connections look fine, a technician should test the thermistor resistance and inspect the water level pressure sensor and its hose for clogs, damage, or wiring faults producing the abnormal 24.5 kHz frequency.
