GE Dishwasher Error Code F145

F145 means the inverter board has detected that the incoming AC voltage is incorrect or outside its acceptable range. The inverter is a critical component that drives the wash motor, and it monitors supply voltage continuously. When the voltage falls outside expected parameters, the inverter shuts down and stores this fault code to alert a technician.

No, you should not attempt to run the dishwasher while this code is active. The fault indicates a voltage irregularity that could damage the motor, the inverter board, or other electronic components if the appliance is forced to operate. Address the root cause before resuming use.

A reset may temporarily clear the code, but it will return if the underlying voltage problem has not been corrected. Resetting without addressing the root cause, whether that is a house voltage issue, a faulty harness, or a failed inverter, will not provide a lasting fix. Always complete the full diagnostic sequence before relying on a reset.

Some steps are DIY-friendly, such as checking and resetting the circuit breaker, verifying outlet voltage with a multimeter, and inspecting visible harness connectors for corrosion or loose fit. However, if the inverter board itself needs replacement, that repair involves working near line-voltage components and is best handled by a qualified technician.

If the fix is as simple as addressing a wiring connection or a house voltage issue, costs may be minimal or limited to a service call fee, typically in the range of $75 to $150. If the inverter board needs replacement, parts and labor combined can range from $200 to $450 depending on the specific model and local labor rates.
