Quick answer
FAE4 and F10E4 are one KitchenAid entry: diverter valve error, with a power cycle as the step.
Model compatibility: KitchenAid reuses codes across series and model years, so FAE4 / F10E4 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
Diverter valve error; cycle power.
One entry, two names
KitchenAid’s help site covers “FAE4 or F10E4” in a single article. The potential cause is a diverter valve error, and the sole troubleshooting instruction is to cycle power. The title puts both forms next to each other without saying why, so whichever your display shows, this is the entry for it.
Cycling the power
Resetting the control sometimes clears problems, KitchenAid says, much as restarting a computer does. The dishwasher must be disconnected for 30 seconds.
Plugs into an outlet: unplug, wait 30 seconds, plug back in.
Hard wired: switch off the breaker feeding it at the home electrical panel, wait 30 seconds, switch the breaker on.
Role of the diverter valve
This is general explanation and not from the article. A diverter directs wash water to one spray path at a time, so a diverter valve error means the control has trouble with that part. KitchenAid’s owner help says nothing about testing or replacing the valve and lists no step beyond the reset.
A second appearance
Owners get nothing more from the article. If the code is back after the power cycle, book service and say the power was already cycled.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
