This guide covers Understanding Kitchenaid Error Codes with practical, technician-backed advice.
KitchenAid appliances across ranges, refrigerators, dishwashers, and washers use error codes to flag specific problems, and while exact codes vary by model and appliance type, most fall into a handful of general categories. This glossary explains those categories in plain language so you can understand what’s likely wrong before calling for service.
Understanding the Understanding Kitchenaid Error Codes
Below, our specialists break down everything you need to know about the Understanding Kitchenaid Error Codes.
Sensor and Temperature Codes
Temperature Sensor Error — Indicates the appliance’s control board isn’t receiving a valid signal from a temperature sensor (thermistor), often due to a wiring issue or a failed sensor component, common on ovens, refrigerators, and dishwashers alike.
Overheat Error — Triggered when an internal temperature sensor detects heat beyond safe operating limits, which shuts the appliance down as a safety measure rather than allowing continued operation; this often points to a ventilation blockage or failing heating element.
Door and Latch Codes
Door Open/Not Latched Error — Common on dishwashers, ovens with self-clean cycles, and washers, this code means the control board isn’t detecting the door switch signal confirming the door is fully closed and latched, which is required before certain cycles can run.
Door Lock Failure — Indicates the electronic door lock mechanism (used on dishwashers and self-cleaning ovens) failed to engage or disengage properly, often due to a worn lock motor or a misaligned door.
Water and Drainage Codes
Fill Error — Appears on dishwashers and washers when the unit doesn’t detect water reaching the expected level within a set time, which can point to a closed water supply valve, a clogged inlet filter, or a failed water level sensor.
Drain Error — Indicates the appliance detects water isn’t draining within the expected time, often caused by a clogged drain hose, blocked filter, or failing drain pump.
Communication and Control Board Codes
Communication Error — Occurs when internal components, such as the main control board and a display or motor control module, fail to exchange signals properly, sometimes due to a loose wiring harness connection rather than a fully failed component.
Control Board failure — A broader code indicating the main control board itself has detected an internal problem, which often requires professional diagnosis to confirm whether the board needs replacement or whether it’s reacting to a failure elsewhere in the appliance.
Motor and Mechanical Codes
Motor Overload Error — Indicates a motor (in a washer, dishwasher pump, or garbage disposal) is drawing more current than expected, often due to a mechanical obstruction preventing normal rotation.
Spin Sensor Error — Specific to washers, this code appears when the control board doesn’t receive an expected signal confirming drum rotation, which can indicate a belt, motor, or sensor issue.
Power and Voltage Codes
Power Surge Error — Indicates the control board detected an irregular voltage event, which can trigger a protective shutdown; this is more common after a storm or power outage and doesn’t always indicate a hardware failure once power stabilizes.
Low Voltage Warning — Appears when an appliance detects incoming voltage below its normal operating range, which can point to a household electrical issue rather than a problem within the appliance itself and is worth having an electrician check if it recurs.
What to Do When You See an Error Code
Start by checking your owner’s manual for the exact code definition specific to your model, since the same letter-number combination can mean different things across different appliance types. Many codes can be cleared by power-cycling the appliance (unplugging it for a minute or switching off the breaker), which resets the control board and clears codes triggered by temporary glitches rather than genuine component failures. If the code returns after a reset, it’s usually pointing to a real underlying issue worth having diagnosed.
