The kenmore dishwasher f2 error code appears on Kenmore dishwashers built by Whirlpool, identifiable by a 665-prefix model number, and it specifically means a water leak has been detected inside the base of the unit. When the built-in leak sensor picks up water pooling where it should not be, the control board halts the cycle immediately, in most cases activating a drain pump to remove standing water as a protective measure rather than continuing to fill or wash.
What causes the F2 code
- A worn or cracked door gasket that lets water escape during the wash or rinse cycle
- A loose or failed hose connection at the water inlet valve or pump
- A cracked tub, sump, or spray arm allowing water to leak internally
- Excess suds overflowing the tub, which the sensor can also register as a leak
- A faulty leak sensor itself, triggering false readings with no actual water present
First checks you can do
- Open the dishwasher and inspect the door gasket for visible cracks, tears, or gaps
- Check underneath the unit (with power off) for any standing water or dampness
- Confirm you are using dishwasher-specific detergent, not dish soap, which produces excess suds that can trigger a false leak reading
- Look at the water inlet valve and hose connections behind the lower kickplate for visible drips
When to call a technician
Because the F2 error code specifically means a real or sensed water leak, this is not a code to ignore or reset repeatedly, since an actual leak can damage flooring and cabinetry if it continues unnoticed. Our dishwasher repair technicians can pinpoint whether the leak is coming from the door gasket, a hose connection, or the tub itself, and confirm whether the leak sensor is reading correctly. You can review other codes on Whirlpool-built Kenmore dishwashers at /error-codes/dishwasher/.
How to prevent it
Use only dishwasher-formulated detergent, inspect the door gasket periodically for wear, and avoid overloading the unit in a way that blocks the door from sealing fully. Catching a worn gasket early, before it fails completely, is far less disruptive than dealing with a leak that has already reached the floor.
A note on Kenmore’s OEM-built dishwashers
A 665-prefix Kenmore dishwasher was built by Whirlpool, while a 587-prefix model was built by Frigidaire and uses an entirely different problem system – see our guide on 587-series Kenmore dishwashers if that applies to your unit instead. Checking your model number confirms which platform you actually have.
Why leak sensors matter more than they seem
Whirlpool built the leak-detection sensor into these dishwashers as a genuine safety feature, not a nuisance alert, because a slow leak from a cracked hose or worn gasket can go unnoticed under a cabinet for weeks, eventually warping flooring or damaging surrounding cabinetry before it becomes visible. Treating the kenmore dishwasher f2 error code as an early warning rather than an annoyance to reset past is the safest approach, even on the occasions where the eventual cause turns out to be a false reading from a worn sensor rather than an actual leak.
Quick summary
In short, an F2 code on a 665-series Kenmore dishwasher means the unit sensed water where it should not be, and the fastest path to a fix is checking the door gasket, hose connections, and detergent type before assuming the sensor itself is responsible, since those three checks together resolve the majority of reported cases without any parts replacement at all.
If you suspect a real leak or the F2 code keeps returning, our experienced, independent technicians can diagnose and repair the issue using genuine OEM parts, backed by a 30-day labor warranty. Schedule service at /schedule/. General Kenmore information is available at kenmore.com.
