KitchenAid Dishwasher
Error Codes

1-1 Control Board Memory Fail High The wash program halts partway through, the door unlocks, and pressing Start has no effect until the power is cut and restored. View -> 2-1 Thermistor Fault Medium Without confirmed water temperature, the heated dry and sanitize steps may not run correctly, leaving dishes damp and poorly cleaned. View -> 4-1 Heating Element Failure Medium The heated wash and heated dry phases depend on the same circuit — when heating fails, dishes exit the cycle cold and dripping wet. View -> 5-1 Door Switch Failure Medium Pressing Start produces no response — the pump and water valve never activate — because the board does not see a confirmed latch signal. View -> 6-1 Water Inlet Valve Fail Medium During the fill stage the pump activates but the water level in the sump is low, resulting in poor spray arm pressure and incomplete cleaning. View -> 6-2 Overflow Float Triggered High Opening the door after the 6-2 code appears reveals water that exceeds the normal wash level and may be close to the door seal. View -> 7-1 Diverter Motor Failure Medium When the diverter motor stalls in one position, water pressure is directed to only one spray zone, leaving the opposite rack poorly rinsed. View -> 8-1 Drain Pump Failure High Opening the dishwasher door reveals two to three inches of murky water sitting in the sump, indicating the drain pump never completed its evacuation. View -> F2 E2 Keypad Shorted Key Medium Every key press is ignored because the control board has detected a continuously closed contact on the keypad and locked out all user input. View -> F3 E1 Wash Thermistor Out of Range Medium The dishwasher fills and the wash pump starts, but the cycle stops within the first ten minutes when the thermistor value is confirmed out of range. View -> F6 E1 No Water Fill Detected Medium The cycle initiates, the control board commands a fill, but no rushing water sound follows — the tub stays dry and F6 E1 appears within 90 seconds. View -> F8 E1 Overflow Flood Detected High In overflow events the excess water may escape through the door gasket, door vent, or under the appliance and spread onto the floor. View -> F9 E1 Drain Timeout Error High Regardless of which wash cycle is selected, the dishwasher always ends with two to four inches of water in the sump that the pump never removed. View ->
