Why Is My Dishwasher Light Blinking

In today’s fast-paced world, we rely heavily on household appliances to make our lives easier and more convenient. One such appliance that has become a staple in many homes is the dishwasher. It’s a true time-saver, allowing us to say goodbye to the tedious task of washing dishes by hand. However, what do you do when you walk up to your dishwasher, only to find its lights blinking in a perplexing pattern? Don’t worry; this article will unravel the mystery of why your dishwasher’s lights are blinking and what steps you can take to resolve the issue.

Understanding the Blinking Lights

1. Check for Error Codes

The first step in deciphering the blinking lights on your dishwasher is to understand if they are indicating an error code. Most modern dishwashers are equipped with a diagnostic system that uses these blinking lights to communicate problems. Refer to your dishwasher’s manual to identify the specific error code associated with the blinking lights.

2. Overloaded Dishwasher

Sometimes, a dishwasher might blink its lights if it’s overloaded. Overloading can obstruct the spray arms, preventing proper water circulation and cleaning. Ensure you’re not cramming too many dishes into the dishwasher and try running a smaller load.

3. Door Not Fully Closed

Another common reason for blinking lights is an improperly closed dishwasher door. Ensure that the door is securely latched shut. If it’s not closed properly, the dishwasher may refuse to start or display error codes.

Troubleshooting the Issue

Power Cycle

A simple power cycle can often reset your dishwasher’s electronics and resolve the blinking lights issue. Turn off the dishwasher at the power source, wait for a few minutes, and then turn it back on. This can help clear minor glitches.

Check Water Supply

Inadequate water supply can also trigger blinking lights. Ensure that the water inlet valve is fully open and there are no kinks in the water supply line. An interrupted water flow can lead to dishwashing problems.

Clean Filters and Spray Arms

Blocked filters and clogged spray arms can disrupt the dishwasher’s performance and cause blinking lights. Regularly clean these components to ensure proper water flow and optimal cleaning.

Seeking Professional Help

Call Customer Support

If the blinking lights persist despite your best efforts, it’s time to reach out to the dishwasher manufacturer’s customer support or a certified technician. They can provide guidance and may schedule a service visit if needed.


A blinking light on your dishwasher can be an unsettling sight, but it doesn’t have to be a cause for panic. By following the steps outlined in this article, you can troubleshoot and potentially resolve the issue on your own. From checking for error codes to ensuring proper dishwasher maintenance, understanding the reasons behind the blinking lights puts you one step closer to a cleaner and more efficient dishwasher.

If the issue persists, it’s best to contact the dishwasher manufacturer’s customer support or a professional technician for further assistance.
