Lights
The lights on your KitchenAid dishwasher are indicator lights, meaning they help you figure out what your dishwasher is doing and why. For example, there is generally a light for each cycle. Some models also have a light to indicate the current load is clean. The number and position of lights will vary depending on the model. For a complete list of indicator lights in your model, check its use and care guide.
Electricity Problems
If the indicator lights on your dishwasher won’t light at all, the first thing to check is the electricity. Make sure the power is on and the dishwasher is plugged into a working outlet and the fuse or circuit breaker isn't blown or tripped.
Blown Out Bulbs
Another reason your indicator lights aren’t working is that the LED bulb has blown out. This is especially evident if some lights are working and others aren't. This simple problem requires disassembling the door, which should only be done by a certified KitchenAid repair technician. Otherwise, you may void your manufacturer’s limited warranty or any extended warranty you paid for.
Blinking
Some KitchenAid dishwashers blink or flash their indicator lights when an error has occurred. Depending on the model, it may be just the start button, or all of the indicator lights blinking in unison. The unit shuts down and you can’t run any cycle while the error lights are blinking. The number of blinking lights can tell a technician which error the unit is experiencing. Call for service through KitchenAid’s customer service line at 1-800-422-1230.
