What FF means on a GE dishwasher

The FF error code on a GE dishwasher indicates that a line power failure occurred during an active wash cycle. This means the dishwasher lost its supply of AC line voltage at some point while a cycle was running, causing the control board to register an incomplete or interrupted operation. The control system logs this event so that the user or technician is aware the cycle did not complete under normal conditions.

Because the dishwasher's control board relies on continuous AC power to execute cycle logic, sequence timers, and component commands, any interruption to line voltage forces the controller into a fault state. This can happen due to a tripped circuit breaker, a momentary utility power outage, a loose or failing connection at the wall outlet or junction box, or a problem with the home's electrical supply. The dishwasher itself is not necessarily faulty; the fault is often external to the appliance.

The first recommended diagnostic step is to reprogram the dishwasher by resetting its control system. This clears the logged fault and allows the user to attempt a fresh cycle. If power has been restored and is stable, the dishwasher should operate normally after reprogramming. Recurring FF codes point toward an intermittent power supply issue that warrants further electrical investigation at the circuit level rather than at the appliance itself.

Common causes of FF

  1. 01

    Tripped circuit breaker

    Wiring / connection

    A momentary overload or fault on the kitchen circuit can trip the breaker, cutting power to the dishwasher mid-cycle. Check the electrical panel for a tripped breaker and reset it before reprogramming the dishwasher.

  2. 02

    Utility power outage

    Wiring / connection

    A brief or extended outage from the utility provider will interrupt power to the dishwasher during a cycle and trigger the FF code. Once power is restored, reprogramming the control clears the fault.

  3. 03

    Loose wiring at the junction box or outlet

    Wiring / connection

    A loose wire connection at the dishwasher's hardwired junction box or at the wall outlet can cause intermittent power loss during operation. Inspect all connections for tightness and signs of arcing or heat damage.

  4. 04

    Faulty wall outlet or power cord connection

    Part replacement

    If the dishwasher is plug-connected, a worn or failing outlet can drop voltage intermittently under load. Test the outlet with a multimeter to confirm it is delivering consistent voltage.

  5. 05

    Control board power supply failure

    Part replacement

    In less common cases, an internal power supply component on the control board may be failing, causing the board to lose regulated power during a cycle even when line voltage is present. This is typically identified only after all external power sources have been ruled out.

Frequently asked questions about FF

What does FF mean on a GE dishwasher?
The FF code on a GE dishwasher means that a line power failure occurred while the dishwasher was running a cycle. The control board detected that AC power was interrupted before the cycle could complete. The code is a logged record of that event rather than an indication of an internal component failure. Reprogramming the dishwasher is the first recommended step to clear the code.
How do I fix the FF error code on my GE dishwasher?
Start by reprogramming the dishwasher to clear the fault from the control board. Check your home's circuit breaker panel to make sure the dishwasher's breaker is not tripped, and reset it if needed. Inspect the wiring connections at the junction box or outlet for looseness or damage. If the code returns repeatedly, investigate the home's electrical circuit for intermittent power issues.
Will resetting the dishwasher clear the FF code?
Yes, reprogramming or resetting the dishwasher is the first recommended diagnostic step and will typically clear the FF code. If the power failure was a one-time event such as a utility outage or a breaker trip that has since been resolved, the dishwasher should return to normal operation after the reset. If the code reappears after resetting, the underlying power supply issue has not been resolved.
Is the FF error code on a GE dishwasher a safety concern?
The FF code itself does not indicate a dangerous condition inside the dishwasher, but the cause of the power failure should be investigated. A repeatedly tripping breaker or signs of arcing or heat at wiring connections are electrical hazards that should be addressed by a qualified electrician before continuing to use the appliance. Once the electrical supply is confirmed to be stable and safe, the dishwasher can be reprogrammed and used normally.
How much does it cost to repair a GE dishwasher showing an FF code?
In many cases there is no repair cost at all because the FF code is triggered by an external power event such as an outage or a tripped breaker that requires no parts. If the issue involves a faulty outlet, wiring repair costs typically range from $75 to $200 depending on the work needed. If the control board requires replacement, parts and labor costs can range from $150 to $400 or more depending on the specific model and service rates in your area.
