What does the 'PF' error code mean on my LG washer?
### **What Does the ‘PF’ Error Code Mean?**
'PF' stands for **Power Failure**. LG has equipped its washing machines with a helpful "power failure recovery" system. When a cycle is interrupted by a loss of electricity, the washer saves its place. Once power is restored, the 'PF' code appears on the display to alert you to what happened .
This feature is designed to let you easily resume the cycle from where it stopped, saving your detergent and time. It is **not** an indication of a mechanical defect or a problem with the washer's internal components .
### **Why Did the ‘PF’ Code Appear?**
In most cases, the cause is external to the washing machine. Here are the most common reasons you might see this error:
- **Power Outage:** A brief or extended power cut from your utility company is the most frequent cause.
- **Loose Power Cord:** The washer's plug may have been knocked loose from the wall outlet .
- **Tripped Circuit Breaker:** Your home's electrical breaker for the laundry room may have tripped and reset itself, or a fuse has blown.
- **Using an Extension Cord:** Power strips and extension cords can have their own reset switches or can fail to deliver stable power, especially during the high-energy demands of a wash cycle. LG strongly recommends plugging your washer directly into a wall outlet .
- **Voltage Fluctuation:** A sudden drop (brownout) or spike (surge) in your home's electrical supply can be interpreted by the washer as a power failure .
### **How to Solve the ‘PF’ Error on Your LG Washer**
Before you call for service, follow these simple troubleshooting steps. In nearly all cases, one of these actions will resolve the issue.
#### **Step 1: The Simple Reset**
This is the most effective solution and should always be your first step.
1. **Clear the Code:** Press the **Start/Pause** button on your washer's control panel . This will often clear the error and resume the cycle. The machine should remember what it was doing and continue from the point the power was lost.
2. **Power Cycle the Machine:** If pressing Start/Pause doesn't work, turn the washer off. Wait about 10 seconds, and then turn it back on. If the 'PF' code is gone, you can select a new cycle or resume the old one.
#### **Step 2: Check the Power Connection**
If the code returns, you need to investigate your home's electrical supply.
1. **Inspect the Outlet:** Make sure the washer's power cord is pushed firmly and securely into the wall outlet .
2. **Check for Damage:** Look at the power cord along its entire length. If you see any cuts, fraying, or burn marks, stop using the washer and have the cord replaced by a professional.
3. **Test the Outlet:** Plug a different appliance, like a lamp or a phone charger, into the same outlet. If that device doesn't work, you have a household electrical problem. Check your home's **circuit breaker panel** or **fuse box** for a tripped breaker or blown fuse .
4. **Ditch the Extension Cord:** If you are using an extension cord or a surge protector, remove it immediately. Plug the LG washer directly into a wall outlet to ensure it receives the full, stable current it needs .
#### **Step 3: Run a Test Cycle**
Once you've confirmed the power supply is stable and the code is cleared, run a short test cycle (like Rinse & Spin). Stay nearby for the first 5-10 minutes. If the machine stops and shows 'PF' again, it indicates the power interruption is recurring, pointing to an issue with your home's wiring or a faulty outlet, which may require an electrician.

### **Preventing the ‘PF’ Error in the Future**
- **Avoid High-Power Sharing:** Do not run other high-powered appliances (like a space heater, iron, or hair dryer) on the same circuit as your washer. The combined draw can cause a voltage drop.
- **Consider a Surge Protector:** While you shouldn't use a standard power strip, a high-quality, dedicated **appliance surge protector** (designed for refrigerators or washers) can protect your washer's sensitive control board from damaging voltage spikes that can also cause PF errors .
- **Inspect Your Outlet:** If your plug feels loose when you insert it into the wall, the outlet's internal grips are worn. This loose connection can generate heat and cause intermittent power loss. An electrician should replace the outlet.
### **When to Call for Service**
While the 'PF' code itself is not a service issue, if you have performed all the checks above—ensuring a secure wall outlet, a working circuit breaker, and no extension cords—and your washer still frequently shuts off or will not turn on at all, there may be a different underlying problem.
In rare cases, a persistent power failure error can point to a faulty **control board** or **loose internal wiring** . Since working with internal electrical components is dangerous and can void your warranty, you should **contact LG Support or a qualified appliance repair technician** if the problem persists despite a confirmed good power source.
In summary, the 'PF' error on your LG washer is a helpful feature, not a defect. In the vast majority of cases, it is solved by pressing a button or simply plugging the machine in properly.
