CodeMeaning
577-0577-0 on a KitchenAid dishwasher is a control board internal fault code that appears in the service diagnostic mode rather than during normal operation. It indicates that the control board has logged a specific internal fault in its memory. This code is typically read during a service call using the built-in diagnostic sequence rather than appearing spontaneously on the normal display.
medium
8-4The 8-4 error code on a KitchenAid dishwasher means the control board detected a heater circuit fault - the heating element did not raise water temperature to the required level within the expected cycle time. This numeric code appears on KitchenAid models with a digital display and is equivalent to the Clean light 7-blink code on indicator-only models.
medium
9-1The 9-1 error code on a KitchenAid dishwasher means the diverter disc did not move to its expected position during a cycle. The diverter system routes wash water between the lower, upper, and (on KDTM models) third rack spray zones. When the diverter disc fails to advance to the next position, the control board registers 9-1. This is the same fault as Clean light 9 blinks on models without a numeric display.
medium
CLEAN-4-BLINKFour blinks of the Clean light on a KitchenAid dishwasher means the water temperature thermistor is open - the control board is not receiving a valid temperature reading from the thermistor that monitors wash water temperature. The dishwasher cannot regulate heating properly without this sensor.
medium
CLEAN-7-BLINKSeven blinks of the Clean light on a KitchenAid dishwasher means the control board detected a fault in the heater circuit. The dishwasher's heating element did not raise the water temperature to the target level within the expected time. This code corresponds to fault 7-1 in models that display numeric codes.
medium
CLEAN-8-BLINKEight blinks of the Clean light on a KitchenAid dishwasher means the control board has detected low wash performance - the dishwasher completed a cycle but the washing conditions (water pressure, temperature, or spray arm function) were below minimum thresholds. This is not typically a component failure - it is a performance fault that points to maintenance issues.
low
CLEAN-9-BLINKNine blinks of the Clean light on a KitchenAid dishwasher means the diverter valve or diverter disc motor has a fault. The diverter system controls which spray arm zone receives water during the wash cycle - routing water between the lower spray arm, upper spray arm, and (on KDTM models) the third rack spray bar. A failed diverter means water may only spray from one zone.
medium
E1 F9E1 F9 on a KitchenAid dishwasher means the control board detected that the drain cycle took longer than the allowed time - typically 2 minutes without the float switch being satisfied. The dishwasher shuts down to prevent flooding. The cause is almost always a physical restriction in the drain path rather than an electrical component failure.
medium
E4 F8E4 F8 on a KitchenAid dishwasher is the same fault as F8 E4 - a water fill failure or anti-flood float trigger. The code is displayed in two different orders across KitchenAid models depending on software version. Both E4 F8 and F8 E4 mean the dishwasher either did not fill with water in time or the base pan anti-flood float was raised by accumulated water.
medium
F8 E4F8 E4 on a KitchenAid dishwasher means the control board did not detect that the dishwasher filled with water within the expected time, or the anti-flood float switch under the unit has been triggered by water in the base pan. The dishwasher shuts down to prevent damage. This is the highest-volume fault code for KitchenAid dishwashers.
medium
F9 E1F9 E1 on a KitchenAid dishwasher is the same long drain fault as E1 F9 - the control board detected that the drain cycle exceeded the allowed time. The two display orders (F9 E1 and E1 F9) refer to the same fault and appear on different KitchenAid models depending on firmware version. The drain did not complete within 2 minutes.
medium
HUBKitchenAid dishwashers display fault codes in three formats depending on the model: alphanumeric codes (F8 E4, E1 F9), numeric codes (8-4, 9-1, 577-0), and blink codes on models without a numeric display (the Clean light blinks in patterns). Understanding which format your model uses is the first step to diagnosis.
medium
POPO on a KitchenAid dishwasher display is not an error code. It means the Delay Start feature is active and the dishwasher is waiting to begin its cycle at the programmed delay time. The dishwasher is counting down the delay period and will start automatically when the countdown reaches zero.
low
CodeMeaning
DOOR-ERRORThe 'Open/Close Door' error on KitchenAid microwaves is identical to the Whirlpool microwave door error because KitchenAid microwaves are manufactured by Whirlpool. The same 3 door interlock switches, door hooks, and diagnostic approach apply.
medium
F1 E5F1E5 on a KitchenAid microwave indicates the humidity sensor used for sensor cooking has failed or is reading out of range. KitchenAid microwaves are Whirlpool-manufactured, so this code is shared with Whirlpool models.
low
HUBKitchenAid microwave error codes are identical to Whirlpool codes because KitchenAid microwaves are manufactured by Whirlpool. The same F/E code system, door interlock switches, and touchpad membranes are used.
medium
CodeMeaning
F1 E0F1E0 on a KitchenAid oven means the control board's EEPROM (Electrically Erasable Programmable Read-Only Memory) has failed. The EEPROM stores the oven's calibration data, model configuration, and operational parameters.
high
F1 E1F1E1 on a KitchenAid oven indicates a communication fault within the control board or between the control board and a secondary board (on double oven models). The main board cannot verify its internal state.
high
F2 E0F2E0 on a KitchenAid oven specifically indicates the Cancel/Off key circuit is shorted. This is more specific than F2E1 which indicates any key - F2E0 points directly to the cancel key circuit on the keypad membrane.
medium
F2 E1F2E1 on a KitchenAid oven means the control board detected a keypad key stuck in the pressed position, most commonly the Cancel/Off key circuit. This is the same code as Whirlpool F2 E1.
medium
F9 E0F9E0 on a KitchenAid oven means the door latch will not release after self-clean. The latch motor ran the self-clean cycle but the bimetal lock mechanism has not cooled enough to release, or the latch motor itself has failed.
medium
CodeMeaning
HUBKitchenAid refrigerator error codes are based on the Whirlpool platform. The most common code is PO (Power Outage), followed by temperature and ice maker related faults.
