GE Washer Error Code 0B

The 0B code on a GE washer means the machine detected that water is still remaining in the wash basket after the drain cycle. The washer uses a pressure sensor to monitor water level by reading a frequency output, and when that reading indicates water is still present, the 0B fault is triggered. The cycle stops to prevent further operation with undrained water. Common sources include drain system blockages, improper standpipe height, or a faulty pressure sensor.

It is not recommended to continue running the washer while the 0B code is active. The code indicates water is not draining as expected, and forcing additional cycles could lead to water remaining in the drum for extended periods or potential overflow. Address the underlying drain issue before resuming normal use.

Repair costs vary depending on what component is at fault. If the fix is simply adjusting the standpipe height or clearing a clogged hose, there may be little to no parts cost involved. Replacing the drain pump typically runs in the range of $75 to $200 for the part, while a new pressure sensor is generally in the $20 to $60 range. Adding professional labor costs can bring the total repair to anywhere from $100 to $350 or more depending on your location and the specific diagnosis.

Start by verifying that the drain standpipe height matches the installation specifications. Then inspect the drain hose for kinks or clogs and check the drain pump for any blockage from foreign objects. If the physical drain path looks clear, inspect the pressure sensor hose for cracks or disconnection and consider testing the pressure sensor frequency output to determine if the sensor itself needs replacement.

A reset may temporarily clear the 0B code and allow the washer to restart, but the code will return if the root cause has not been corrected. If the drain path is obstructed or the pressure sensor is faulty, the fault condition will be detected again during the next drain cycle. Clearing the code is only a lasting fix if it was triggered by a one-time event such as a temporary blockage that has since been removed.
