LG Washer Error Code 5

Error code 5 on an LG washer signals a pressure sensor error, meaning the Sensor Switch Assembly is not functioning correctly. This component monitors the water level inside the drum. When it fails or sends an out-of-range signal, the washer stops operation and displays this code to prevent damage from incorrect water levels.

Running the washer while error code 5 is active is not recommended. The pressure sensor controls water fill levels, and operating without a functioning sensor could lead to overfilling, leaking, or running the drain pump without water present. It is best to stop using the machine until the fault is diagnosed and repaired.

A reset, typically performed by unplugging the washer for a few minutes and restarting, may temporarily clear the error display. However, if the underlying fault with the Sensor Switch Assembly or its associated wiring and hose is still present, the error code will return. A reset is useful for confirming whether the fault is intermittent, but it does not substitute for diagnosing and repairing the root cause.

Some causes of error code 5 are DIY-friendly. Checking the pressure sensor hose for kinks, clogs, or cracks and reseating the electrical connector at the sensor can sometimes resolve the issue without parts. If the Sensor Switch Assembly itself has failed, replacing it requires basic disassembly skills and sourcing the correct replacement part for your model. If you are uncomfortable working with appliance wiring, a qualified technician is recommended.

If only the pressure sensor hose needs cleaning or repositioning, there may be no parts cost at all. Replacing the Sensor Switch Assembly typically costs between $20 and $60 for the part alone, depending on the model. If a technician performs the repair, total costs including labor generally range from $100 to $200.
