The “PF” error code on your LG dishwasher isn’t an error code in the traditional sense. It indicates that the dishwasher experienced a power interruption while it was running. This guide will help you diagnose and resolve the LG dishwasher PF error code, getting your dishwasher back to work quickly.
Understanding LG dishwasher PF Error Code
The PF code simply informs you that the dishwasher lost power during a cycle. It’s not a sign of a malfunction within the dishwasher itself, but rather a problem with the power supply. When power is restored and you press the Power button, the dishwasher will typically resume the cycle from where it left off.
LG dishwasher PF Error Code: Troubleshooting Steps
Before calling a technician, try these troubleshooting steps:
- Check the power cord and outlet:
- Ensure the power cord is securely plugged directly into a functioning wall outlet. Avoid using extension cords or surge protectors, as they can sometimes interfere with the dishwasher’s power supply. If you’ve been using one, remove it and plug the dishwasher directly into the wall.
- Reset the GFCI outlet:
- If the dishwasher is connected to a Ground Fault Circuit Interrupter (GFCI) outlet (often found in kitchens and bathrooms), it might have tripped. Look for a “Reset” button on the outlet and press it. A GFCI trips to protect against electrical shocks, and sometimes minor power fluctuations can cause them to activate.
- Check the circuit breaker:
- Locate your home’s circuit breaker panel. Find the breaker that controls the dishwasher (it should be labeled). If the breaker is tripped (the switch will be in the “Off” or middle position), flip it fully to the “Off” position, wait a few seconds (about 5 seconds is sufficient), and then flip it back to the “On” position.
- Test the Outlet:
- To determine if the problem lies with the outlet or the dishwasher, plug another appliance (like a lamp or a small kitchen appliance) into the same outlet. If the other appliance works, the problem is likely with the dishwasher’s internal wiring or connections (requiring professional service). If the other appliance doesn’t work, the issue is with the outlet itself, and you may need to consult an electrician.
- Check for loose wiring (for Direct Wired Units):
- If your dishwasher is direct wired (not plugged into an outlet), there may be a loose wire connection. Caution: Working with electrical wiring can be dangerous. If you are not comfortable working with electrical wiring, please contact a qualified electrician.
Important Electrical Information
- Dedicated Circuit: Your LG dishwasher should be connected to a dedicated 15-amp, 120-volt AC circuit. This prevents overloading the circuit and ensures a stable power supply.
- Grounding: Proper grounding is essential for safety. The dishwasher must be connected to a grounded electrical system.
- Professional Installation: It is highly recommended to have the dishwasher installed and electrically connected by a qualified technician in accordance with local electrical codes. This ensures safety and proper operation.
- Permanently Connected Dishwashers: If your dishwasher is permanently wired, it must be connected to a grounded metal, permanent wiring system, or an equipment-grounding conductor that must be run with the circuit conductors and connected to the equipment-grounding terminal or lead to the appliance. The ground wire should be connected to the green ground connector in the terminal box.
What Happens After Power Restoration?
As mentioned, when power is restored and you press the Power button, the dishwasher should resume the cycle from where it was interrupted. This is a normal operation and not a cause for concern.
