What the F230 error code actually means

Your GE dishwasher has stopped working and is showing an F230 error because the main control board has detected a problem with the heating system's wiring or a safety device connected to the heater. This could be a loose wire, a tripped safety component, or a failed control board. A technician will need to inspect those connections and possibly replace the control board to get the dishwasher running again.

Questions people ask about F230

What does F230 mean on a GE dishwasher?
F230 indicates that the machine control board has detected a fault related to the heater circuit. Specifically, it flags a problem with the heater's thermal cutout (TCO) or the AC wiring harness connections. The dishwasher will stop operating until the underlying cause is identified and corrected. In some cases, the control board itself has failed and needs replacement.
Is it safe to use my GE dishwasher with an F230 error?
No, you should not run the dishwasher while the F230 error is active. This code can indicate a fault in the heater circuit, which involves high-voltage AC components. Operating the appliance before the issue is resolved could worsen the fault or create a safety hazard. Disconnect power until the repair is completed.
How much does it cost to repair an F230 error on a GE dishwasher?
Repair costs depend on which component has failed. A replacement heater TCO is generally an inexpensive part, typically in the range of $10 to $40. A new machine control board tends to cost more, usually in the range of $100 to $300 for the part alone, with additional labor costs if you use a professional technician.
How do I fix an F230 error on a GE dishwasher?
Start by disconnecting power to the dishwasher, then inspect all AC harness connections at the control board and heater assembly for loose, corroded, or damaged connectors. Test the heater TCO for continuity and replace it if it has failed. If the wiring and TCO are both in good condition, replacing the machine control board is the next step.
Will resetting my GE dishwasher clear the F230 error?
A reset may temporarily clear the error code, but it will return if the underlying problem is not fixed. The F230 fault is triggered by a condition the control board actively detects, such as a failed TCO or a loose harness connection, so resetting without repairing the root cause will not resolve the issue.
