(SOLVED) Why Dishwasher keeps Beeping and How to Stop it?

Why does my dishwasher keep beeping?

The main reason why a dishwasher keeps beeping are because of a faulty sensor, an open door, anti-flood mechanism, or power overload.


  • Incorrect use
  • Faulty parts
  • Open door
  • Anti-flood mechanism
  • Overload
  • Stuck float switch
  • Power outage
  • Obstruction to spray arms
  • Insufficient rinse aid


As mentioned above, the beep might also be due to a stuckfloat switch, a power outage, an obstruction to the dishwasher spray arms, or insufficient rinse aid.


The list mentioned highlights some of the key reasons for a beeping dishwasher. There are a few other reasons as well that can trigger the beep. The beep can be because of any one or more than one reason at a time. It’s important to check the cause of the problem and fix it before continuing to use the dishwasher.


How to stop a dishwasher from beeping?

You can stop a dishwasher from beeping by using it as intended, replacing faulty components, closing an open door, and removing water in the casing. Making sure that the dishwasher is not overloaded, resetting the dishwasher, clearing the obstruction to the spray arms, and adding the required rinse aid can also help.


The fixes in most cases are quite simple and can be done by yourself without the assistance of any technician or tools. They also take very less time to get done.


  1. Check your dishwasher manual to see if you’re operating the dishwasher as intended. You have likely missed out on a step or two. Attending these steps will stop the beep.
  2.  Look out for faulty components in the dishwasher and get them replaced to arrest the beeping sound. The dishwasher is equipped with a heating element and multiple sensors. There are chances that one or more of them have worn out due to wear and tear. A beeping sound after the wash cycle is often due to a defective heating element. In some cases, the heating element replacement can be expensive and a complete dishwasher replacement is more cost-effective.
  3. Watch out for an open door of the dishwasher and close it properly. The dishwasher has chances of beeping if you opened the door part way through the wash cycle or didn’t latch it properly. This is a good chance to check for a broken door latch that stops the door from getting closed and changing it.
  4. Check if the beeping sound is accompanied by blinking lights in the dishwasher. If so, it indicates that the anti-flood mechanism has been activated. In most cases, this happens when the sensors perceive water in the dishwasher casing and stop the dishwasher from working further to avoid water leakage on the floor from the drum. You can just tilt the dishwasher to drain the water if it’s a standalone unit or use a sponge to wipe the excess water in an integrated model.
  5. Ensure that you’re not overloading the dishwasher with too many utensils to get the work done fast. You must always remember not to exceed the specified weight limit.
  6. Reset the dishwasher if there is a power outage. You can do this by disconnecting the dishwasher from the power source and keeping it that way for at least five minutes and then connecting it once again.
  7. Check if there is any object that is preventing the free rotation of the spray or rotating arm of the dishwasher and remove it. This can be as simple as some food waste under the arm.
  8. Inspect the dispenser to check if there is sufficient rinse aid like coarse aid. You can look up the user manual to find out how much rinse aid is needed and fill the dispenser accordingly.
  9.  Clean blocks in the water outflow valve that prevents the water from draining out after the dishes are done and get this cleared at the earliest. These blocks will not allow you to open the dishwasher door to prevent the floor from getting flooded.
  10. Make sure that the seal of the dishwasher is in good condition and free of cracks. A cracked seal can cause a leaking dishwasher and result in inappropriate water levels. The inappropriate water levels can pave way for the beeping sound.
  11. Remove clogs in the filter system under the dishwasher due to debris, dust, and food particles. You’ll have to take it off to clean it by doing a quarter counterclockwise turn of the filter. Replace it properly after the cleaning is done.
  12. Seek the assistance of a professional to assess problems with the internal electrical system. This is especially needed if the beep sound occurs after a recent power surge resulting in the frying of internal circuits.

Why does my Whirlpool dishwasher keep beeping?

Your Whirlpool dishwasher keeps beeping because the door is opened, there is no soap, the reed sensor is faulty or there is loose wiring.


  1. Make sure that the door of the dishwasher is closed during operation. This is a good chance to check for and replace a faulty latch that prevents the door from getting closed properly.
  2. Ensure that the detergent dispenser is filled with the right type and quantity of soap. The dispenser shouldn’t be overfilled resulting in an overflow of the detergent.
  3. Check for worn out, malfunction, or breakage of the reed sensors and get new ones fitted in place of the damaged ones.
  4. Look out for loose wiring connections and reconnect them. If the wiring harness is broken, do a replacement.


Why does my GE (General Electric) dishwasher keep beeping?

Your GE (General Electric) dishwasher keeps beeping due to obstruction to spray arms, the start button is pressed twice or a momentary power cut.


  1. Ensure that the spray arms are capable of rotating freely by moving one or more utensils that are in the way and blocking the movement of the arms.
  2. Make sure that you press the Start button only once. If the button is pressed twice, it can trigger a restart and the dishwasher will beep during the restart process.
  3. Check if there has been a momentary power cut following which the dishwasher has restarted. The beep will stop automatically after two minutes.


Why does my Kenmore dishwasher keep beeping?

Your Kenmore dishwasher keeps beeping because the dishwashing cycle is complete, there are errors within the circuit board or a malfunctioning component.


  1. Check if the beeping sound occurs at the end of the dishwashing cycle. If so, this isn’t a cause of concern as it’s just an indication that the washing cycle is completed.
  2. Inspect for the possibility of electrical errors in the circuit board following a power outage or surge. You can try resetting the dishwasher to fix the problem and stop the beep sound.
  3. Look out for malfunctioning components in the dishwasher and get them replaced. The beeping sound will stop when the faulty components are replaced.


Why does my Samsung dishwasher keep beeping?

Your Samsung dishwasher keeps beeping due to leak detection, a stuck float switch, or overload.


  1. Look out for leakage signs and get the leaks set right at the earliest. The leaks can cause the anti-flood mechanism to get activated, which in turn triggers the beep sound.
  2. Tap the float switch with mild pressure to release it if it’s stuck. You can also remove utensils that are under the float out of the way resulting in getting stuck.
  3. Ensure that the dishwasher isn’t overloaded and you don’t put load it with more than the capacity specified in the user manual.


Why does my Bosch dishwasher keep beeping?

Your Samsung dishwasher keeps beeping because the dishwasher isn’t draining, the flow meter is broken or the cycle selector is stuck.


  • Remove the filters from under the dishwasher and clean them well. You can replace them if they are damaged. If the problem doesn’t get set right, seek professional assistance.
  • Check for a broken flow meter and get a new one fitted by a professional. This is a sensor that calculates the flow and amount of water in the dishwasher.
  • Choose a cycle apart from the one already selected and see if the dishwasher starts up while stopping the beep at the same time. A stuck cycle selector can prevent the dishwasher from processing the selected option.
