GE Washer Error Code D

Error code D on a GE washer is a Redundant Flood Condition alert. It means the backup processor recorded an extended period of pressure readings at or near 18.0 inches of water column, which is close to overflow level. This is a secondary safety system fault, meaning the primary flood protection may not have responded properly. The washer stops operation to prevent water damage.

No, you should not run the washer while error code D is active. This code indicates that water levels reached a near-overflow condition and the backup safety system had to intervene. Continuing to operate the machine without diagnosing the cause risks actual flooding, water damage to your home, and potential damage to the washer's electrical components.

A reset may temporarily clear the error code from the display, but it will not fix the underlying problem. Because this fault is logged by the backup processor after an extended period of high pressure readings, the same conditions will likely trigger the code again if the root cause is not addressed. It is important to diagnose and repair the pressure tube, sensor, or inlet valve before resuming normal use.

Start by checking the pressure tube for trapped water, kinks, or disconnections, as this is the most common cause. Drain any water from the tube and reattach it securely if it has come loose. If the tube is clear and properly connected, the next step is to inspect the water level pressure sensor and the water inlet valve for signs of failure. If those components are functioning correctly, the main control board may need to be evaluated.

Repair costs vary depending on the root cause. If only the pressure tube needs to be cleared or reattached, the cost may be minimal or involve only a service call fee in the range of $75 to $150. If a component like the pressure sensor or water inlet valve needs replacement, parts and labor typically range from $150 to $350. A main control board replacement is the most expensive scenario, often ranging from $250 to $500 or more depending on the model.
