GE Washer, Dryer Error Code 18

Error code 18 means the drain pump clearing algorithm failed. The washer ran the drain pump for the maximum allowed continuous time but the pressure sensor never confirmed the tub was empty. This points to a drainage problem, most often a blocked pump, clogged filter, or restricted drain hose.

A reset may clear the code temporarily, but if the underlying cause is not resolved, the error will return as soon as the washer attempts another drain cycle. The pressure sensor must confirm an empty tub within the allotted drain time for the cycle to complete successfully. Resetting without addressing the blockage or faulty component is not a lasting fix.

If the fix is simply clearing a clog from the pump filter or hose, the repair may cost nothing beyond your time. Replacing a drain pump typically runs between $75 and $200 depending on the part cost and whether you hire a technician. Pressure sensor replacement is generally less expensive, often falling in the $30 to $100 range for parts, with additional labor costs if a professional is involved.

Start by checking and cleaning the drain pump filter, which is the most common source of blockages. Next, inspect the drain hose for kinks or clogs at the standpipe connection. If those are clear, test the drain pump for proper operation and inspect the pressure sensor air tube for cracks or kinks. Replacing a failed pump or pressure sensor will be required if the components themselves are defective.

It is not advisable to continue running the washer while this error is active. The machine stopped the cycle because it could not confirm the tub drained properly, and running additional cycles risks leaving standing water in the drum, potential overflow situations, or additional stress on the pump motor. Resolve the drainage issue before resuming normal use.
