GE Dishwasher Error Code F144

F144 indicates that the dishwasher's control system has detected an inverter error. The inverter module controls the wash pump motor speed and operation, and when the control board receives a fault signal from it, it logs F144 and stops the cycle. Diagnosis starts with inspecting the wiring harness and connectors, and may require replacing the inverter module if wiring is found to be intact.

A reset may temporarily clear the F144 code, but if the underlying problem with the inverter or its wiring is still present, the fault will return as soon as the dishwasher attempts to run a cycle. A reset is a useful first step to confirm whether the fault is persistent, but it does not substitute for proper diagnosis and repair of the inverter system.

If only the wiring harness needs to be repaired or reconnected, costs can be relatively low, typically in the range of $75 to $150 for a service call and labor. If the inverter module itself needs to be replaced, parts and labor combined can range from $200 to $400 or more depending on the specific model and local labor rates. Getting a technician diagnosis first is the best way to understand the actual repair cost before committing.

A knowledgeable DIYer can start by checking the harness connectors leading to the inverter for obvious damage, corrosion, or loose connections, and re-seating them if needed. However, if the inverter module itself has failed, replacing it involves working with internal electronics and electrical connections that are best handled by a qualified technician. Always disconnect power to the dishwasher before inspecting any internal components.

You should not continue operating the dishwasher while F144 is active. The code indicates a fault in the inverter, which controls the pump motor, and running the appliance in this condition could cause additional damage to the motor or control electronics. The dishwasher will typically halt operation on its own when this fault is detected, which is a built-in protection measure.
