LG Washer Error Code dV

The dV code on an LG washer indicates a drain valve problem. The washer has detected that the drain valve is not operating correctly, either because of a loose or defective wiring connection or because the valve itself has failed. The machine stops the cycle to prevent potential water damage until the issue is resolved.

A reset may temporarily clear the dV code from the display, but it will not fix the underlying problem. If the drain valve connection is faulty or the valve itself has failed, the error will return as soon as the washer tries to use the drain valve again. The root cause must be repaired before the machine will operate normally.

If the fix is simply reseating a loose connector, there may be no parts cost at all, only the cost of a service call if you hire a technician, which typically ranges from $75 to $150. If the drain valve itself needs replacement, parts costs generally range from $30 to $90 depending on the model, with total repair costs including labor typically falling between $100 and $250.

Start by unplugging the washer and locating the drain valve wiring connector. Disconnect and firmly reseat the connector, checking the terminals for corrosion or damage. If reconnecting the wiring does not clear the code, the drain valve likely needs to be replaced. If you are not comfortable working with appliance wiring or internal components, contact a qualified technician.

It is not recommended to continue using the washer while the dV code is active. A malfunctioning drain valve can prevent water from draining properly, which can lead to water remaining in the drum, potential overflow, or further damage to internal components. The washer should remain unplugged until the issue is diagnosed and corrected.
