Samsung Dishwasher Normal Light Flashing and Beeping: Fix It

You press start on your Samsung dishwasher, but the normal light keeps flashing and it starts beeping — very annoying, right? You might feel confused or even worried that something is broken. But don’t worry! In this article, you will learn how to fix this problem with simple steps.

Check the Dishwasher Door Is Closed Properly

When your Samsung dishwasher normal light is flashing and beeping, the first thing to check is the door. This is because the machine won’t start unless the door is fully closed and locked. Even if it looks closed, sometimes it is not tight enough. This is one of the most common reasons behind the flashing light and sound.

Open the door again and close it with a firm push. Make sure nothing is stuck inside the door area, like a fork or spoon, that could stop it from closing all the way. Look at the latch — this is the small lock that holds the door tight. If it’s dirty or broken, the machine won’t know the door is closed.

Sometimes the door latch can wear out over time. If the latch is loose or not clicking into place, it may need to be replaced. You can test this by opening the door and slowly closing it. Listen for a ‘click’ sound. That sound means the latch is working right.

Also, check the rubber seal around the door. This is the soft part that makes sure no water leaks out. If this seal is broken or dirty, it can stop the door from closing fully. Clean the seal with a soft cloth and warm water. If it looks damaged, you might need to get a new seal.

Make sure the dishwasher is not too full. Overloading it can push against the door and stop it from locking. Try removing a few items and then closing the door again.

  • Open and close the door again firmly
  • Check for any items blocking the door
  • Listen for the latch clicking sound
  • Clean the rubber seal
  • Don’t overload the dishwasher

Reset the Dishwasher with a Power Cycle

If your Samsung dishwasher is still flashing and beeping after checking the door, the next thing to try is a reset. This is like giving the machine a fresh start. A simple reset can fix many small problems.

To do this, turn off the dishwasher using the power button if it has one. Then unplug it from the wall. If it’s hard to unplug, you can turn off the circuit breaker instead. Wait at least 5 minutes. This gives the machine time to clear its memory.

After 5 minutes, plug it back in or turn the breaker on. Then try to start a new wash cycle. In many cases, the flashing light and beeping will stop after this step. This method works well if the machine had a glitch or software error.

If your model has a reset button, use that instead. Some Samsung dishwashers have a button combo like ‘Start’ and ‘Cancel’ that you press for a few seconds to reset. Check your user manual to find the right buttons.

Sometimes, a power surge or power cut can confuse your dishwasher’s computer. A power cycle helps it return to normal. Think of it like restarting your phone when it starts acting strange.

Also, make sure your power source is working right. If the outlet is bad, the dishwasher might start and stop, causing it to beep and flash.

  • Turn off the dishwasher
  • Unplug it or turn off the breaker
  • Wait at least 5 minutes
  • Plug it back in and start a new cycle
  • Use reset buttons if your model has them

Clean the Water Inlet Filter and Check the Supply

Water problems are another reason why your Samsung dishwasher may beep and flash the normal light. The machine needs the right amount of water at the right time. If the water is not coming in properly, it will give you a warning.

Start by turning off the water supply to the dishwasher. Then, find the water inlet valve. This is usually at the bottom front of the machine. The water goes into the dishwasher through this valve, and there’s a small filter inside it.

Take out the hose that brings water in. Then gently remove the filter. It can look like a small mesh screen. If it’s full of dirt or sand, water can’t flow through. Clean it under running water. Use a soft brush if needed.

Check the hose too. Make sure it’s not bent or twisted. A bent hose can stop water from getting in. Also, check if the water supply is turned on fully. Sometimes people turn it off by mistake.

Put the filter back in and reattach the hose. Then turn on the water and run a test cycle.

If your house has low water pressure, the dishwasher may not work right. Try using the dishwasher at night when other appliances are not using water.

  • Turn off water supply
  • Remove and clean water inlet filter
  • Check hose for bends or block
  • Turn water back on
  • Test with a new cycle

Make Sure the Drain Is Not Blocked

A blocked drain can also cause the flashing light and beeping. If the dishwasher can’t drain the dirty water, it will stop working to protect itself.

Open the dishwasher and take out the bottom rack. You will see a small filter at the bottom, usually round or square shaped. Twist or lift it out gently. Under this filter is the drain area.

Check for food bits, grease, or anything blocking the drain. Clean it with a soft cloth and hot water. If it’s very dirty, use a toothbrush to scrub gently.

Look inside the drain hose at the back. This hose carries water out of the machine. If it’s clogged or bent, water can’t drain properly. Remove the hose and clean it with warm water or a long flexible brush.

Also check where the hose connects to your sink or garbage disposal. Sometimes this area gets blocked too.

Run a short rinse cycle to see if the water drains out. You should hear a swishing sound as the water moves out. If not, the drain pump might be faulty, and you may need help from a repair person.

  • Remove and clean bottom filter
  • Check drain area for food or grease
  • Clean the drain hose
  • Make sure hose is not bent
  • Try a rinse cycle to test drain

Inspect the Float Switch and Sensor System

The float switch is a small part inside your dishwasher that tells the machine when there’s enough water inside. If the float gets stuck or the sensor does not work, it can cause the dishwasher to beep and flash.

You will find the float inside the bottom of the dishwasher, usually a small round or dome-shaped part. It should move up and down freely. Try lifting it gently. If it feels stuck, clean around it.

Sometimes food bits or hard water buildup can stop it from moving. Use warm water and a cloth to clean the area. If the float doesn’t move freely, the dishwasher thinks it is full of water and will not start.

Under the float is a switch. If the float works but the switch is broken, the machine won’t know the right water level. The switch may need to be replaced.

There are also sensors inside that read temperature, water level, and other things. If these sensors get dirty or fail, they can send wrong signals. This causes the normal light to flash and the beeping to start.

To clean sensors, remove the filter and spray area. Use vinegar and warm water to wash the inside. Run a short cycle to rinse everything.

  • Find and move the float switch
  • Clean around the float
  • Check if the float moves freely
  • Clean spray arms and inside with vinegar
  • Run a rinse cycle to test

Update the Control Panel or Call for Service

If you’ve tried everything and your Samsung dishwasher still has a flashing normal light and keeps beeping, it might be a control board issue. This is the part that controls all functions of the dishwasher.

Over time, the board can get damaged by moisture, power issues, or just regular use. Sometimes, it just needs a small update. Newer dishwashers might get software updates, and you can do this by checking the manual or Samsung website.

Also look for any blinking pattern in the lights. Some Samsung models show error codes through the lights. You can count the flashes and check what they mean in the user manual.

If the control panel is dirty or wet, it can also cause buttons not to work right. Clean it with a dry cloth. Do not use water on the buttons.

If none of this works, it’s time to call for service. A professional can check the control board, sensors, pump, and wiring. This will help you avoid guessing and maybe even save money by replacing only the part that is bad.

  • Check if software updates are available
  • Clean control panel gently
  • Watch for flashing patterns (error codes)
  • Read your user manual for codes
  • Call a repair service if all else fails

Final Thoughts

If the problem still continues after trying everything, don’t worry — a repair expert can help. Your dishwasher will work fine again soon with a little care and time.

Frequently Asked Questions (FAQs)

Is it normal for the dishwasher to beep during a cycle?

No, it is not normal for your Samsung dishwasher to keep beeping during a cycle. A small beep when starting or ending the cycle is okay. But if it keeps beeping, it usually means something is wrong. It could be the door is not fully closed, the drain is blocked, or water is not entering properly. You should check the control panel for blinking lights and try to reset the dishwasher. If the beeping does not stop after a power cycle, follow the steps above to find and fix the issue.

Can the beeping stop if I reset the dishwasher?

Yes, in many cases the beeping will stop after you reset the dishwasher. Resetting clears small glitches or software errors. To reset, unplug the dishwasher or turn off the power from the breaker. Wait for 5 minutes and then turn it back on. This simple action often stops the beeping and clears the flashing light. If it keeps happening after a reset, then it may be a hardware problem that needs more attention.

Do I need to clean the filters often?

Yes, you should clean the dishwasher filters regularly. Food, grease, and small bits can get stuck and block water flow or drainage. When the filters are dirty, your dishwasher might beep and flash a warning light. Try cleaning the filter once every week or two, depending on how often you use the machine. It only takes a few minutes and can help keep your dishwasher working properly without errors.

Is it okay to open the door while it’s beeping?

You can open the door if the dishwasher is beeping, but be careful if it is still running. Wait for the water to stop spraying. Opening the door may stop the sound, but it won’t fix the real issue. Check if the door latch is closing tightly. Also, look at the control panel for flashing lights. These signals help you understand what’s wrong. Opening the door can give you a closer look inside to start checking and fixing the problem.

Can a power cut cause this problem?

Yes, a power cut or power surge can confuse the dishwasher’s system. After the power returns, the machine might show blinking lights and make beeping sounds. This happens because it was stopped suddenly. The best thing to do after a power cut is to reset your dishwasher. Turn it off, unplug it for 5 minutes, and plug it back in. Then start a new cycle. This helps the machine start fresh and stop beeping.

Do I need tools to fix the flashing light issue?

No, most of the time you do not need any special tools to fix the flashing light and beeping problem. You can fix many of these things using your hands and a soft cloth. For cleaning the filter or checking the hose, maybe a soft brush or toothbrush is helpful. But usually, everything can be done at home with very simple items.

Is it dangerous if I ignore the flashing light?

It is not dangerous, but you should not ignore the flashing light and beeping. It means your dishwasher needs your attention. If you keep using it without fixing the issue, it may cause bigger problems like leaks or damage to parts. Fixing the small issue now can save you time and money later. It’s best to stop and find the cause before using it again.

Can I still use the dishwasher if it’s beeping?

No, you should not use the dishwasher while it is beeping and the normal light is flashing. These signals mean the machine has stopped working properly. Using it like this could lead to water damage or more errors. Always fix the reason behind the beeping first. After that, you can start a new cycle safely.
