F9E1
KitchenAid Dishwasher
Severity: ModerateWhat Does This Error Mean?
F9E1 means your KitchenAid dishwasher's diverter valve has faulted — this valve directs water from the pump alternately to the lower spray arm and the upper spray arm (and third rack where fitted). When the diverter valve fails, one or more spray zones stop receiving water, resulting in poorly washed dishes. The fault is usually a failed diverter motor, a jammed valve plate, or a blocked water path.
Affected Models
- KitchenAid KDTM354DSS
- KitchenAid KDTE334GPS
- KitchenAid KDFE104HPS
- KitchenAid KDFM404KPS
- KitchenAid KDPM604KPS
Common Causes
- Failed diverter motor not rotating the valve to the correct position
- Broken or cracked diverter valve disc or vane jammed in one position
- Food debris or broken glass fragment lodged in the diverter valve chamber
- Wiring harness connector to the diverter motor loose or corroded
- Control board not sending the correct signal to the diverter motor
How to Fix It
-
Cancel the current cycle, switch off the circuit breaker, and allow the machine to drain any standing water. Remove the lower dish rack.
Accessing the diverter valve requires a clear, dry tub bottom.
-
Remove the lower spray arm by pulling it straight up (no tools needed on most KitchenAid models). Then unscrew or unclip the spray arm hub and set aside.
The diverter valve is directly beneath the spray arm mount in the sump assembly.
-
With a flashlight, inspect the visible parts of the sump area for broken glass, fruit pits, bones, or any debris that could be jamming the diverter valve plate.
Small items that pass through the filter can still reach the diverter valve area and wedge in the rotating disc.
-
Remove any debris found with tongs or needle-nose pliers — never use bare hands if you suspect broken glass. Reassemble the spray arm components.
Even a small shard of glass can prevent the diverter disc from rotating.
-
Restore power and run a short wash cycle. Listen for the diverter switching — you should hear a soft thunk approximately every 60–90 seconds as it switches between wash zones.
If you hear the switching sound and F9E1 clears, a debris blockage was the cause.
-
If F9E1 returns or you hear no diverter switching at all, the diverter motor or valve assembly has failed mechanically. Schedule professional repair.
Diverter valve assemblies typically cost $30–$70 and a technician can usually replace one in 30–45 minutes.
When to Call a Professional
The diverter valve assembly is located in the sump area below the tub and requires partial disassembly to access. Replacement is straightforward for a technician but involves removing the lower spray arm mount and sump cover. Contact KitchenAid service or a qualified appliance repair company with your model number.
Frequently Asked Questions
What does the diverter valve actually do in a dishwasher?
The wash pump runs continuously during a cycle, but most dishwashers have separate upper and lower spray arm zones. The diverter valve acts like a traffic controller — it rotates to direct the water flow alternately to the lower spray arm, upper spray arm, and (on some models) a third-rack spray bar. This way one pump can service all spray zones.
My dishwasher washes the lower rack fine but the upper rack dishes come out dirty — could this be F9E1?
Yes — this is a classic symptom of a diverter valve stuck in the lower position, delivering water only to the lower spray arm. Even if F9E1 has not yet appeared on the display, a partially failing diverter can cause this uneven wash performance. Inspect the diverter area for debris and listen for the switching sound during a cycle.
Can I use the dishwasher while waiting for a diverter valve repair?
Technically the machine will run, but wash performance will be poor — typically either the upper or lower rack will not be cleaned properly. For lightly soiled loads you may choose to hand-wash the poorly served items. However, if F9E1 is actively displayed, the machine may lock out the cycle completely.
