Have you ever been blindsided by an error code from your dryer and you realize you don’t have a clue what to do next? Don’t feel alone, we all have at some point. As usual, Neli is at your service! Today’s list of dryer error codes applies to Whirlpool’s Duet dryer models, and many will crossover to others. 

Please refer to our other lists for your particular model. More lists are coming, so be sure to check back for more. In the meantime, remember you can always contact us to set up a virtual appointment with one of our certified technicians. 

We’ll discuss the issue on the phone (optional, of course) and we can also stream live video and voice to help you pinpoint the problem and make the repair or we’ll get the correct part number if needed. Gotta love it! 


PF – Power Failure. This is a useful indicator that tells you anytime the dryer loses power while it’s running. When you restore the power, press CANCEL to reset the display or START to continue the existing cycle. It’s a good idea to find out why the dryer lost power. Maybe a failed breaker, loose or burnt power cord pigtail connections. 

L2 or F4E4 – Low Line Voltage. The L2 leg of the 240Vac is missing according to the control. To confirm, check the voltage at the terminal block at the back of the dryer. If you don’t know how, contact us right away and we can show you via video chat. You will need a multimeter for this. We can help you with that, too.  

If you have a meter and you’re comfortable using it, check the incoming voltage at the terminal block for 240 Vac. The L2 leg supplies power to the heater, providing 240 Vac at the heater terminals. 

Confirm all connections are tight (not just snug). A loose connection here causes eventual arcing and overheating at the block, sometimes melting the wire completely off. Replace or repair any connection that seems suspect to you. You need to err on the side of caution. Don’t take chances. Confirm every connection is in their proper place! You know what to do if you have questions. 

F1E1 – Main control or user interface (UI) control failure. Most times, this represents a communication fault between the main control and UI. Try cycling the power to the dryer and try again.

F2E1  – Stuck UI button. The control sees a stuck button somewhere on the user interface (UI). You can try rubbing your fingers across the buttons to free them up.

F3E1 or F3E2 – Outlet thermistor failure. Check the outlet thermistor wiring first. Repair or replace the harness when necessary. The resistance of the thermistor is about 10K ohms at room temperature.

F3E5 – The control is sensing connector P14 on the main control is loose or disconnected. Check and correct. 

F3E6 – Moisture sensor failure. The first place to check is the sensor connections. They tend to get damaged when the dryer is serviced and the harness is not tucked away before closing up the machine.

F3E7 – Moisture sensor shorted. Look for a metal object stuck under the two metal sensor strips. Sometimes, broken zippers and hairpins end up there. Remove any obstruction and then clean the sensor strips with rubbing alcohol. As usual, check the sensor harness, too. 

F4E1 – Heater relay failure. The symptom here is likely no heat. They locate the heater relay on the main control and is non-serviceable.

F4E3 or AF – Restricted or blocked air flow. There are three things to check for this error. A blocked lint screen, blocked or crushed vent, or the blower isn’t turning. Check the vent for proper airflow. If that’s good, confirm the blower is turning at the correct speed. If not, it might be stripped on the motor shaft or a belt might be slipping, too. Also, a foreign object like a sock or other garment might cause a restriction. 

F6E1 or F6E2 – Communication error. A loss of communication between the user interface (UI) and the main control. Try cycling power as with other errors, but this one is likely to stay. The problem is you can’t tell which board lost communication, but most times it’s caused by the main control.
