GE Dishwasher Error Code F218

F218 indicates that a fault has been detected on the machine control board of the GE dishwasher. The control board's own internal diagnostics have flagged an error it cannot resolve on its own. This code points directly to the control board as the faulty component, not to any external sensor or peripheral part. Replacement of the machine control board is the recommended corrective action.

A power reset is unlikely to permanently clear the F218 code because it reflects an internal hardware fault on the control board, not a temporary software glitch. The code may disappear briefly after a reset but will typically return once the dishwasher attempts to run a cycle. Board replacement is required to resolve the fault permanently.

The cost to repair the F218 error depends on whether you hire a technician or replace the board yourself. A replacement machine control board for a GE dishwasher typically ranges from around $80 to $250 or more depending on the model. Adding professional labor, total repair costs can range from $150 to $400 or higher. Comparing the repair cost to the age and overall condition of the appliance is a useful step before committing to the repair.

A knowledgeable DIYer comfortable with appliance repair can replace the machine control board, as it typically involves disconnecting a wiring harness and swapping the board. However, you should ensure the dishwasher is fully disconnected from power before beginning any work. Sourcing the correct replacement board for your specific GE model is essential to a successful repair.

It is generally not recommended to continue operating the dishwasher while the F218 error is active. A faulty control board can cause unpredictable behavior, including failure to stop filling, improper heating, or the machine not completing cycles correctly. Using the appliance in this condition could potentially worsen the fault or lead to other issues.
