Let’s be honest, there are few modern conveniences we take for granted more than the dishwasher. Until, of course, it stops working. You open it expecting sparkling clean dishes, but instead, you’re greeted by a tiny, incessant, blinking light. It’s a moment that can send a wave of frustration through any homeowner. If you’re currently staring at that flashing LED and wondering What Is The Blinking Light On My Dishwasher, take a deep breath. You’ve come to the right place. That light isn’t a sign of doom; it’s your appliance’s way of trying to talk to you. And we’re here to help you translate.
First Things First: What That Blinking Light Usually Means
Before you start pricing new dishwashers, understand this: a blinking light is almost always an error code or a status indicator. Think of it as your dishwasher’s check engine light. It’s detected a problem—big or small—that’s preventing it from starting or completing a cycle.
The specific meaning can vary wildly between brands and models, but the causes often fall into a few common categories. We’ll walk through the most frequent culprits, from simple fixes you can do in 60 seconds to issues that might require a closer look.
Common Culprits Behind a Blinking Dishwasher Light
More often than not, the problem behind that blinking light is something you can solve yourself without calling a technician. Let’s roll up our sleeves and investigate the usual suspects.
The Door Isn’t Latched Properly
This is the number one cause, and thankfully, the easiest to fix. Your dishwasher has a safety mechanism that prevents it from running if the door isn’t securely closed and latched.
- The Problem: Sometimes, a stray utensil, a bulky pot handle, or an improperly loaded dish rack can prevent the door from closing all the way. The latch might click, but the sensor doesn’t fully engage.
- The Fix: Open the dishwasher and check for any obstructions. Rearrange any dishes that might be sticking out. Close the door firmly until you hear a solid, satisfying click. For many, the blinking light will disappear right then and there.
Water Supply Issues (It’s Thirsty!)
Your dishwasher can’t wash dishes without water. If it can’t draw enough water at the beginning of a cycle, it will typically stop and flash a warning light.
- The Problem: This could be due to a kinked water supply hose behind the unit or a closed or partially closed water valve under your sink.
- The Fix: First, check the valve under your kitchen sink that supplies water to the dishwasher. Ensure it’s fully open. If that doesn’t work, you may need to gently pull the dishwasher out to check the supply hose for any kinks or twists that are restricting flow.
Drainage Problems (A Clogged Artery)
If the dishwasher can’t drain the dirty water from the previous cycle, it won’t start a new one. This is a very common reason for a blinking light.
- The Problem: The most likely offender is a clogged filter. Food particles, bits of paper labels, and other gunk can accumulate in the filter at the bottom of the dishwasher tub.
- The Fix: Locate the filter (usually a cylindrical piece you can twist and pull out) at the bottom of your dishwasher. I’ve personally found everything from olive pits to small shards of glass in mine. Give it a thorough rinse under hot water. While you’re at it, check the drain hose for clogs and ensure the connection to your garbage disposal is clear.
Expert Tip from James Peterson, Certified Appliance Technician: “About 70% of the service calls I get for a dishwasher that won’t start are related to a simple clog. Before you call for help, always spend five minutes cleaning the filter. It’s amazing how often this solves the problem and saves the customer a service fee.”
The Wash Cycle Was Interrupted
Did you have a brief power outage? Or maybe you opened the door mid-cycle to toss in one last spoon? This can confuse your dishwasher’s electronic brain. It might pause the cycle and blink to let you know it needs instructions.
- The Fix: Try pressing the “Start/Resume” button. If that doesn’t work, you may need to cancel the cycle entirely (often by holding the “Cancel” or “Start” button for 3-5 seconds) and then start a new one.
A Step-by-Step Guide to Diagnosing the Blink
Feeling a bit overwhelmed? Just follow this simple, logical process.
- Observe the Pattern: Is it a specific light blinking, like “Clean” or “Sanitized”? Is it blinking a certain number of times, pausing, and then repeating? This pattern is often a specific error code.
- Do a “Soft Reset”: The oldest trick in the tech support book works for dishwashers, too. Turn the dishwasher off at the circuit breaker for about 5-10 minutes. This can reset the control panel and clear a temporary glitch.
- Check the Holy Trinity: Before doing anything else, always check the three most common issues:
- Door: Is it securely latched?
- Water: Is the supply valve fully open?
- Drain: Is the filter clean?
- Consult Your User Manual: I know, I know. But your dishwasher’s manual is the ultimate decoder ring. It will have a troubleshooting section that tells you exactly what a specific blinking pattern means for your model. If you’ve lost it, a quick Google search for your dishwasher’s model number followed by “manual” will usually find you a digital copy.
What is the blinking light on my dishwasher telling me about specific brands?
While the general principles are the same, some brands have their own quirks. Here are a few examples:
- Bosch: A blinking “Clean” light often indicates the cycle was interrupted. A blinking red light on the floor (for models with InfoLight) can signal a leak or a drainage issue.
- Whirlpool & KitchenAid: A blinking “Start/Resume” light often means the cycle was paused. You just need to press it to continue. Other lights may blink in a pattern that corresponds to an error code in the manual.
- GE: On many GE models, the start light will blink if the door is opened during a cycle. To resume, you often need to press “Start” again within a few seconds of closing the door.
This is why your manual is your best friend. It turns a mysterious blink into a clear, actionable piece of information.
Preventing Future Blinks: Smart Dishwasher Maintenance
The best way to deal with a blinking light is to prevent it from happening in the first place. Good dishwasher maintenance is key.
- Scrape, Don’t Rinse: Scrape large food particles off plates before loading, but don’t pre-rinse them. Modern dishwasher detergents have enzymes that need some food soil to work on.
- Clean the Filter Weekly: Make it a habit. A clean filter ensures proper drainage and better cleaning performance.
- Load It Properly: Don’t overcrowd the machine. Ensure nothing is blocking the spray arms or the detergent dispenser. Learning how to properly load a dishwasher can dramatically improve its longevity.
- Run a Cleaning Cycle Monthly: Use a dishwasher cleaning tablet or run an empty cycle with a cup of white vinegar in a bowl on the top rack to descale and deodorize the interior.

When to Call a Professional
You’ve tried everything. You’ve cleaned the filter, reset the power, checked the hoses, and the light is still blinking. Now is the time to call a qualified appliance repair technician. Don’t attempt complex electrical or plumbing repairs yourself unless you have the proper experience. Call a pro if:
- The blinking persists after all basic troubleshooting.
- You see any signs of water leakage around the machine.
- The error code in the manual points to a faulty pump, heating element, or control board.
- You hear unusual grinding or humming noises.
Frequently Asked Questions
1. Can I just ignore a blinking light on my dishwasher?
No, you shouldn’t. The blinking light is a signal that something is preventing the dishwasher from operating correctly. Ignoring it could lead to poor cleaning, water damage, or a more serious mechanical failure down the line.
2. How much does it cost to fix a blinking dishwasher light?
The cost can range from free to several hundred dollars. If it’s a simple fix you can do yourself, like cleaning a filter or un-kinking a hose, it costs nothing. If you need a technician, the service call fee alone is often $75-$150, plus the cost of any parts and labor.
3. Why is the “Clean” light blinking on my dishwasher?
A blinking “Clean” light is a common indicator that the wash cycle was interrupted before it could complete its drying phase. This is often caused by opening the door too soon or a brief power flicker. Try closing the door and pressing “Start/Resume” to see if it completes the cycle.
4. Does using the wrong detergent really cause a blinking light?
Yes, it can. Using regular dish soap instead of automatic dishwasher detergent can create a massive amount of suds. Modern dishwashers have sensors that can detect this “oversudsing” and will stop the cycle and trigger an error light to prevent a foamy flood in your kitchen.
5. How do I find my dishwasher’s model number to look up the manual?
The model number is usually on a sticker located on the inside edge of the dishwasher door, either on the top or along the side. It might also be on the frame of the dishwasher tub itself, visible when the door is open.
That Blinking Light Isn’t a Mystery Anymore
That once-dreaded blinking light on your dishwasher should now seem a lot less intimidating. In most cases, it’s a simple communication—a request to latch the door, clear a clog, or just resume the cycle. By working through these troubleshooting steps, you’ve not only learned what is the blinking light on my dishwasher but also gained the confidence to handle one of the most common household appliance hiccups. So next time a light starts flashing, you’ll know exactly what to do.
