F16
Whirlpool Dishwasher
Severity: MinorWhat Does This Error Mean?
The F16 error on your Whirlpool dishwasher means the control board thinks the door is still open, even when it appears to be closed. The door latch switch sends a signal to the board to confirm the door is securely shut. If that signal is not received — or is received incorrectly — F16 appears and the cycle will not start.
Affected Models
- Whirlpool WDF series
- Whirlpool WDT series
- Whirlpool 6th Sense series
- Most Whirlpool dishwashers
Common Causes
- The door latch is not fully engaged — the door was not closed with enough force
- Food debris or buildup is preventing the latch from clicking into the strike plate
- The door latch switch has failed and is not sending the closed signal
- The door hinge or strike plate is misaligned so the latch cannot engage properly
- Wiring damage between the door latch switch and the control board
How to Fix It
-
Open the dishwasher door fully. Check the latch area and the strike plate on the door frame for any food debris or residue.
Even a small buildup of grime can prevent the latch from fully engaging.
-
Clean the latch mechanism and the strike plate with a damp cloth. Remove all debris.
Use a toothpick or thin tool to clear any debris packed into the latch mechanism.
-
Close the door firmly and listen for a solid click. Push on the door to make sure it is fully latched.
Some Whirlpool dishwashers require a firm push to engage — the latch should click audibly.
-
If the door closes and latches physically but F16 still shows, press and hold the Cancel/Drain button for 3 seconds to reset the control board.
The control board may need a manual reset to recognize the door is now closed.
-
If F16 persists with a clean and properly latching door, the door latch switch has likely failed and needs replacement.
A technician can test the switch with a multimeter in about 30 minutes.
When to Call a Professional
If cleaning the latch and firmly closing the door does not clear F16, a technician should test the door latch switch. Door latch replacement is typically $80–$150 including labor. This is a relatively simple repair on most models.
Frequently Asked Questions
Why does F16 appear even though my door clicks shut?
The audible click means the door is physically latched, but the electrical switch inside the latch may still be failing. The latch switch is a separate component from the physical latch mechanism. The switch can fail even when the latch still engages mechanically.
Can I force-start the dishwasher with F16 showing?
No — the machine will not start a wash cycle if it believes the door is open. This is a safety feature to prevent hot water and detergent from spraying into your kitchen. Fix the latch issue before attempting to run the machine.
How long does door latch replacement take?
A technician can typically replace a Whirlpool dishwasher door latch in 30–45 minutes. The door panel usually needs to be removed to access the latch assembly. Parts cost around $20–$50 and labor adds $60–$100.
