F9E4 covers the lower spray arm: mechanical binding or blockage, or an electrical fault in its sensor, motor or drive circuit.
Model compatibility: KitchenAid reuses codes across series and model years, so F9E4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Lower spray arm error: binding or blocked arm, loose or corroded sensor or motor circuit, open fuse, drive circuit, or the LSA motor or sensor.
The part
Down in the base of the tub, the lower spray arm spins and sprays water up at the lower rack. KitchenAid’s service entry for F9E4, “lower spray arm error,” puts mechanical and electrical reasons side by side for why the control may object to it.
Listed mechanical causes
Spray arm binding
Spray arm blocked
Listed electrical causes
A sensor circuit or motor circuit connection that is corroded or loose
Open fuse
Drive circuit
LSA motor or sensor (LSA means lower spray arm)
Owner involvement
No procedure for owners is given. If the arm turned strangely, or a rack or item sat close to it, pass that to the technician. Disassembly is neither suggested by the source nor advised here, and the electrical items require test equipment and wiring access.
One code, two kinds of fault
One code stands for both a jammed arm and a dead motor, so the display alone cannot tell you which it is.
How to read the list
Treat it as a menu of possibilities handed to a technician. Not every item will fit your machine, and the entry does not say they occur together. How common each item is goes unmentioned.
F4E4: a motor entry of its own, for the wash motor
