LG Washer Error Code BALL PRESSURE SENSOR

This error means the washer's ball pressure sensor, which tracks the water level inside the drum, is disconnected or has failed. The machine signals this condition by blinking all water level LEDs on the control panel. In QC Test Mode, it is confirmed when the sensor output number is below 63 or above 70. The fault points to a wiring connection problem or a defective sensor.

It is not advisable to continue using the washer while this error is active. Without a functioning water level sensor, the machine cannot accurately control how much water fills the drum, which could lead to overfilling or improper cycle operation. The washer should be repaired before resuming normal use.

A simple reset is unlikely to permanently clear this error because it points to a physical issue, either a disconnected connector or a failed sensor, rather than a temporary software glitch. The error will return as soon as the washer attempts to read water level data if the underlying problem has not been corrected. The connector and sensor must be inspected and repaired or replaced to resolve the fault.

Start by locating the BLUE 3-pin connector that runs from the ball pressure sensor to the PWB assembly and make sure it is firmly and correctly seated at both ends. Inspect the pins for corrosion or damage and clean or reseat them as needed. If the connection is solid but the error continues, the ball pressure sensor itself should be replaced. Always unplug the washer before inspecting or handling internal components.

If the fix is simply reseating a loose connector, there may be little to no parts cost involved, though a service call fee will apply if you hire a technician. If the ball pressure sensor needs replacement, parts typically range from around $20 to $60 depending on the model, with total repair costs including labor generally falling between $80 and $180. Diagnosing the root cause first can help avoid unnecessary parts purchases.
