What PF means on a Dacor dishwasher

The PF error code on a Dacor dishwasher stands for Power Fail, and it indicates that the appliance experienced an interruption in its electrical power supply. This is a system-level status notification rather than a component fault code. The dishwasher's control board monitors incoming power, and any disruption, whether brief or extended, causes the board to log and display this code when power is restored. The code also appears during initial installation, when the unit is powered on for the first time after being connected to the home's electrical supply.

The most common trigger for PF is a momentary loss of household power such as a brief outage, a tripped circuit breaker, or a GFCI outlet that has tripped on the dishwasher's circuit. Loose wiring connections at the junction box or at the terminal block inside the dishwasher can also cause intermittent power interruptions that register as a PF event. In some cases, voltage fluctuations or a weak connection in the home's wiring can produce repeated PF codes even without a full outage.

Because PF is fundamentally a power continuity notification, it does not necessarily indicate a fault with any internal dishwasher component. The control board simply records that supply power was lost and restores display function once power returns. Pressing START/CANCEL clears the code and returns the dishwasher to normal standby operation. If the code appears repeatedly without an obvious external power event, the circuit wiring and breaker should be inspected before assuming the control board itself is faulty.

Common causes of PF

  1. 01

    Household power outage or interruption

    Wiring / connection

    A brief or extended loss of power to the home will trigger the PF code when electricity is restored. Check whether other appliances or lights in the home were also affected around the same time.

  2. 02

    Tripped circuit breaker or GFCI outlet

    Wiring / connection

    The dishwasher's dedicated circuit breaker may have tripped, or a GFCI outlet on that circuit may have cut power. Inspect the electrical panel and any GFCI outlets near the dishwasher and reset them as needed.

  3. 03

    First-time installation power-on

    Wiring / connection

    PF is a normal display when the dishwasher is connected to power for the first time during installation. Pressing START/CANCEL clears it and the unit will operate normally.

  4. 04

    Loose wiring connection at junction box or terminal block

    Wiring / connection

    A loose or corroded wire connection in the home's junction box or at the dishwasher's internal terminal block can cause intermittent power loss that registers as a PF code. Inspect connections for tightness and signs of arcing or corrosion.

  5. 05

    Faulty control board

    Part replacement

    If PF appears repeatedly without any external power event, the control board itself may be misreading power supply continuity. This is the least common cause and should only be considered after ruling out all wiring and circuit issues.

Frequently asked questions about PF

What does PF mean on a Dacor dishwasher?
PF stands for Power Fail on a Dacor dishwasher. It indicates that the appliance detected an interruption in its electrical power supply at some point. The code also appears normally when the dishwasher is powered on for the first time after installation. It is a status notification, not a component failure alert.
How do I fix the PF error code on my Dacor dishwasher?
Press the START/CANCEL button to clear the PF code and return the dishwasher to normal operation. If the code reappears, check your home's circuit breaker panel for a tripped breaker and inspect any GFCI outlets on the dishwasher's circuit. Persistent or repeated PF codes may point to a loose wiring connection that should be inspected by a qualified technician.
Will resetting the dishwasher clear the PF code?
Yes, pressing START/CANCEL is the recommended step to clear the PF code on a Dacor dishwasher. If the underlying cause was a one-time power outage or initial installation, the code will clear and not return. If it reappears after resetting, there is likely an ongoing issue with the circuit or wiring that needs further investigation.
Is the PF error code on a Dacor dishwasher a safety concern?
In most cases, PF is not a safety concern and simply records that power was lost momentarily. However, if the code is triggered repeatedly by a tripped breaker or GFCI, there may be an underlying electrical issue on the circuit that should be evaluated by a licensed electrician. Loose or arcing wiring connections, if present, do warrant prompt attention for safety reasons.
How much does it cost to repair a Dacor dishwasher showing a PF code?
In many cases the PF code costs nothing to resolve since it clears with a button press after a power outage or at initial installation. If a service call is needed to address a tripped breaker, loose wiring, or a faulty control board, repair costs can range from around $75 to $300 or more depending on the nature of the repair and local labor rates.
