Severity: ModerateWhat Does This Error Mean?
The F26 error means your Whirlpool washer has a door switch problem. The switch that tells the machine the door is closed is not working. The washer won't start without a confirmed door signal.
Affected Models
- WFW5620HW
- WFW6620HW
- WFW9620HC
- Most Whirlpool Duet front-load washers
Common Causes
- Door switch is faulty or has worn out
- Wiring harness connecting the door switch to the control board is loose
- Door not aligned correctly so the switch is never engaged
- Door hinge is bent or broken causing misalignment
- Control board fault not reading the door switch signal
How to Fix It
-
Open and firmly close the door.
Push the door in until you hear a solid click. Make sure nothing is blocking the latch.
-
Check around the door seal for clothing caught in the gasket.
A sock or towel edge in the seal can prevent the door from fully closing.
-
Unplug the washer for 60 seconds and plug back in.
A power reset clears temporary switch signal errors.
-
Try starting the cycle again.
If F26 returns immediately, the door switch or its wiring is faulty.
-
Contact a qualified technician to test and replace the door switch.
The switch can be tested with a multimeter for continuity.
When to Call a Professional
If the door closes fully but F26 persists after a reset — the door switch needs replacing. This is a standard repair for appliance technicians. Expect costs of $100–$200 including parts and labor. Contact Whirlpool support or a qualified technician.
Frequently Asked Questions
What is the difference between F22 and F26 on a Whirlpool washer?
F22 means the door lock mechanism has failed. F26 means the door switch that detects the door is closed has failed. They're different components — the lock holds the door, the switch senses it.
Can I test the door switch myself on a Whirlpool washer?
If you have a multimeter, you can test the switch for continuity. With the door closed, the switch should show continuity. If it reads open, the switch needs replacing.
How much does it cost to replace a Whirlpool washer door switch?
The door switch part costs $15–$45. With professional labor, total repair is $100–$200. It's a quick and affordable repair.
