Help! KitchenAid Dishwasher Error Codes

How KitchenAid codes are built#

KitchenAid dishwashers share the Whirlpool control platform, so the F#E# code format and the diagnostic entry are identical to the equivalent Whirlpool models. The first character group is the system and the second is the specific fault, which means two codes that share an F-number are failures in the same subsystem even when the E-number differs. On KDTM top-control models the code shows on a hidden display at the door's top edge or as a blinking Clean light; on KDTE front-panel models it appears directly on the display. If yours blinks instead of showing text, count the blinks between pauses and map them to a code with the tech sheet — for example, seven blinks is F5E1, a door-switch issue. Reading the code correctly is what saves you from swapping parts by guesswork.

Common codes and what they mean#

How to pull the code yourself#

1. Cut power at the breaker before removing anything, and pull the toe plate (two 1/4-inch hex screws) to find the tech sheet taped inside.
2. Enter diagnostic mode with the model's three-button sequence — commonly a pattern such as Hi Temp, Heated Dry, Hi Temp, Heated Dry within a four-second window.
3. Let the control step through its tests; stored codes usually appear first when you enter diagnostics.
4. Match the F#E# code to the table above, or count blink patterns against the tech sheet on blink-code models.
5. Try a hard reset (breaker off for 10 minutes) before condemning any board — a surge-set code sometimes clears.
6. Confirm the fix by re-entering diagnostics and checking the code has cleared.

Prevent the repeat#

Most board-level codes on the F1 system trace back to power events — surges and breaker trips during an active cycle are exactly what corrupt the EEPROM. A surge protector on the circuit, and not running the [dishwasher](/blog/repair-or-replace-dishwasher) through a lightning storm, prevents a large share of F1E0 and F1E1 faults. For the F8 and F9 water and drain codes, keeping the drain path and the diverter clear stops the fill, level, and drain sensors from flagging a fault that is really just a clog.

Repair or replace?#

Most KitchenAid codes point to a switch, a valve, or a drain clog — inexpensive fixes. A repeat F1E0 or F1E1 after a clean reset means the main board, which on an older KDTM604K is where a repair-or-replace decision belongs. A technician can read the code and quote the exact part.
