LG Washer Error Code 888

The 888 code indicates a water level error where the BP pressure sensor is reading a frequency of 25.0 kHz or higher, which signals to the control board that there is insufficient water in the tub. This causes the washer to stop before running drain or agitate functions as a protective measure. The issue can stem from a water supply problem, a faulty sensing hose, or a failed BP sensor.

No, you should not attempt to run a wash cycle while the 888 code is active. The washer has detected that it cannot confirm an adequate water level, and operating the motor during agitate or drain without proper water could damage internal components. Resolve the underlying cause before restarting the machine.

Repair costs vary depending on the cause. If the fix is as simple as cleaning inlet screens or repositioning a kinked sensing hose, there may be no parts cost at all. Replacing a BP water level sensor typically runs in the range of $20 to $60 for the part, while a water inlet valve replacement generally costs $30 to $80 in parts. If professional labor is needed, expect an additional $100 to $200 depending on your location and service provider.

Several of the most common causes are DIY-friendly. Start by confirming both water supply valves are fully open, then check the inlet hose screens for blockage, and inspect the pressure sensing hose for kinks or disconnection. If those steps do not resolve the error, testing or replacing the BP water level sensor typically requires basic electrical tools and is within reach for experienced DIYers.

A power reset by unplugging the washer for a few minutes may temporarily clear the code, but it will return during the next cycle if the underlying problem is not fixed. The 888 error is triggered by a live sensor reading, so the root cause involving the water supply, sensing hose, or BP sensor must be corrected for the code to stay cleared.
