What PF means on a Jenn-Air dishwasher

The PF code on a Jenn-Air dishwasher stands for Power Failure. It is not a fault with any internal component; it is an informational indicator that the dishwasher's control board detected an interruption in household electrical supply lasting longer than approximately 5 seconds. The control board monitors incoming power continuously, and when power is restored after a qualifying outage, it sets this flag in the display to alert the user that the active wash cycle was interrupted.

Because the dishwasher does not automatically resume a cycle after power is restored, the PF indicator blinks persistently until the user acknowledges it. Acknowledging the code requires either pressing any cycle or options pad on the control panel or unlatching the door. Either action signals to the control board that the user is aware of the interruption, and the display clears. No component repair or replacement is involved in a typical PF condition.

If the PF code appears repeatedly during normal operation without any known power outages, this points to an upstream electrical issue rather than a dishwasher fault. Possible causes include a loose connection at the wall outlet or junction box, a failing circuit breaker that intermittently trips, or voltage fluctuations from the utility supply. In those cases, the electrical supply circuit should be inspected rather than the dishwasher itself.

Common causes of PF

  1. 01

    Household power outage

    Wiring / connection

    A utility-side power outage lasting more than approximately 5 seconds will trigger the PF code when power returns. This is the most common cause and requires no repair.

  2. 02

    Tripped circuit breaker

    Wiring / connection

    A breaker that tripped and was reset will cause the dishwasher to display PF when power is restored to the circuit. Check the breaker panel for a recently tripped breaker serving the kitchen or dishwasher circuit.

  3. 03

    Loose electrical connection at outlet or junction box

    Wiring / connection

    A loose wire connection behind the dishwasher or at the wall outlet can cause brief, intermittent power interruptions that repeatedly trigger the PF code. Inspect the power supply connection and tighten any loose terminals.

  4. 04

    Intermittently failing circuit breaker

    Part replacement

    A breaker that is nearing the end of its service life may trip briefly without fully switching to the off position, causing brief power interruptions. If PF appears frequently with no apparent outage, the breaker should be tested and replaced by a qualified electrician.

  5. 05

    Voltage fluctuations from utility supply

    Wiring / connection

    Significant voltage sags or surges from the utility grid can cause the control board to register a power failure event. If this is suspected, a licensed electrician can install a line voltage monitor to confirm the issue.

Frequently asked questions about PF

What does PF mean on a Jenn-Air dishwasher?
PF stands for Power Failure. It indicates that the dishwasher's control board detected an interruption in electrical power lasting longer than approximately 5 seconds. The code blinks in the display after power is restored and will continue blinking until you press any cycle or options pad or unlatch the door. It is an informational alert, not a component fault.
How do I fix the PF code on my Jenn-Air dishwasher?
To clear the PF code, simply press any cycle or options pad on the control panel, or unlatch the door. Either action acknowledges the power interruption and clears the display. If the code returns frequently without a known power outage, inspect the dishwasher's electrical supply circuit for loose connections or a failing breaker.
Will resetting my Jenn-Air dishwasher clear the PF code?
You do not need to perform a full reset to clear the PF code. Pressing any cycle or options button or opening the door latch is all that is required to dismiss the indicator. If you choose to cycle power at the breaker, the PF code will reappear when power is restored and will still need to be acknowledged at the control panel.
Is the PF code on a Jenn-Air dishwasher a safety concern?
The PF code itself is not a safety concern. It is purely informational and indicates that a power interruption occurred. However, if the code appears repeatedly without any obvious outage, the underlying cause could be a failing circuit breaker or loose wiring, which should be inspected by a qualified electrician for safety reasons.
How much does it cost to repair a Jenn-Air dishwasher showing a PF code?
In most cases there is no repair cost at all, since the PF code only requires pressing a button to clear it after a power outage. If the repeated appearance of the code points to an electrical supply issue such as a faulty breaker or loose wiring, electrician service costs typically range from $75 to $250 depending on the scope of the work needed.
