GE Dryer Error Code 18

Error code 18 means the Drain Pump Clearing algorithm failed. The control ran the drain pump but the pressure sensor never confirmed the tub was empty before the maximum drain time was reached. This points to a problem with the drain pump, the drain hose, the standpipe installation, or the pressure sensor circuit.

You should resolve error code 18 before continuing to use the dryer. The drain system is not completing its cycle, which means water may not be properly clearing from the machine. Continuing to run cycles with a drain fault can lead to water sitting in the unit or incomplete drying performance.

A reset may temporarily clear the error code from the display, but it will return as soon as the dryer attempts another drain cycle if the underlying problem has not been corrected. Resetting alone is not a fix. You need to identify and resolve the root cause, whether that is a blockage, an out-of-spec pump, an improper standpipe height, or a faulty pressure sensor, before the code will stay clear.

Several of the most common causes are DIY-friendly. Start by checking the drain pump for blockages, inspecting the drain hose for kinks or clogs, and verifying your standpipe height matches the installation instructions. If you are comfortable using a multimeter, you can also test the pump resistance at the J512 connector on the control board and compare it to the specified 13.5 ohms. Pump replacement or pressure sensor replacement may require more comfort with appliance disassembly.

If the fix is simply clearing a blockage or adjusting the standpipe height, there may be little to no cost. A replacement drain pump typically runs in the range of $30 to $100 for the part, with additional labor costs if a technician is involved. A pressure sensor replacement is generally in the $20 to $60 range for the part. Total repair costs with professional labor often fall between $100 and $250 depending on what component needs replacement.
