KitchenAid Washer Error Code F15

F15 is a system leak detection fault. The control board uses the same logic as the FH code: it either detected no water entering the tub when it expected fill activity, or the flow sensor counted 10.5 gallons entering the machine without the pressure switch confirming that water accumulated inside. The code indicates water is not staying in the tub as expected, pointing to a physical leak or a sensor fault.

A reset may temporarily clear the F15 code, but if the underlying problem is not repaired, the fault will return as soon as the washer attempts another fill cycle. Resetting without addressing the leak or sensor issue is not a lasting solution and could allow water damage to continue.

Repair costs vary depending on the faulty component. Replacing a pressure switch hose or reconnecting a loose fitting is relatively inexpensive, often in the range of $10 to $40 for parts. A new pressure switch, flow meter, or water inlet valve typically runs $30 to $100 or more for the part, with labor adding $75 to $150 if a technician is needed. A cracked tub is the most costly repair and may approach or exceed the value of an older machine.

Start by inspecting the washer tub for any cracks or holes, then check the pressure switch hose for damage, kinks, or loose connections. If both look intact, test the pressure switch for proper operation and examine the flow meter and water inlet valve. Replacing whichever component is faulty should resolve the code.

It is not recommended to continue using the washer while F15 is active. The code indicates that water may be leaking inside or under the machine, which can cause floor damage, mold growth, or electrical hazards. The machine should remain off until the source of the detected leak is identified and repaired.
