Why Does My Dishwasher Keep Beeping? Reasons Behind a Beeping Dishwasher

Dishwashers have a beeping mechanism that lets the user know that something is wrong. Whether it be just a shortage of detergent or a more serious problem identifying the problem is very easy.

Here are some common problems that make the dishwasher beep constantly:

Unlatched Door

One of the most common and overlooked reasons behind the beeping is an unlatched door. If the door is not properly closed the dishwasher will do the beeping once you start your wash.

It could be something is obstructing the door way not letting it shut properly or a damaged door latch. If the door is not aligned properly it will not close all the way.



The easiest solution is to open the door wide and properly shut it. If that does not do the trick you may have to check for damages on the latch. Check the condition of the door latch.

Overload of Dishes

Dishwasher beeping constantly can also come from a dish overload. There is a standard for the amount of dishes that go in a single wash cycle.

If you are overloading the dishwasher with dishes, it will start beeping to let you know there is a problem. The spray arm in this case can’t move freely inside the dishwasher because of too many dishes.


Overloading can strain the motor and prevent water distribution and flow inside the compartment.


Not only does it make the dishwasher start beeping but it will reduce the cleaning performance of the dishwasher as well if you force the overload.

The fix is very easy. Make sure the dishes are evenly distributed and follow the right way to load the dishwasher. Pull some dishes out when the beeping starts until the sound goes away.

Problem in the Settings

Dishwashers have different settings like rinse only or heavy duty. It also has different modes to control the dishwasher’s behavior.

The beeping can be from a setting like the control lock, sleep mode, or schedule wash being activated. If you select the wrong type of wash or open the door mid-wash it will start beeping.



Double-check the type of wash selected. Rinse only for stuff that is not that dirty and heavy-duty when the whole dishwasher is stacked with dishes.

Do not open the dishwasher mid-wash. Check the control panel to see if any lock setting is on. Turn it off and run the dishwasher. 

If it does not deactivate, try unplugging the dishwasher from the outlet and wait a few minutes before turning it on again.

Short of Detergent or Dishwasher Salt

A deficiency of the dishwasher is also a reason behind the dishwasher beeping constantly. If you do not put in enough detergent or cleaning agent it will start beeping because it cannot fully clean the dishes.

Hard water is also a culprit. If the salt runs out, the detergent will not be able to get rid of the minerals and there will be deposits on the dishes and the bottom of the dishwasher.

This can clog the detergent dispenser causing the dishwasher to start beeping noises.


Check the dispenser to see if it is clogged. Clean it with a thin stick and rinse the excess off. If it is just a shortage of detergent, pour some more into the dispenser.


For hard water issues, get a good dishwasher salt like the Finish one. You can also use all-in-one detergent tablets that have some amount of dishwasher salt in them.


If you want to go toxin-free Ecover has a biodegradable tablet that is nontoxic and based on plant. 

Low Water Levels: Code H2O

Low water levels in the dishwasher are a major reason for the beeping to start. Problems with the water supply can cause low levels inside the dishwasher. If that happens the dishwasher will not be able to function properly.

Dishwashers have a water inlet valve that lets water into the main compartment. If you have a General Electric dishwasher it will throw up a “H2O” error code on the display.


The GE dishwasher randomly beeping is from the H2O code and it will be on the screen on top of the door.


Check the water supply hose for leaks. If it is kinked straighten it up and put the plumber’s tape on the leak spots.

Clean the water inlet valve inside the dishwasher and make sure the main water supply is working. If you need to change the valve or float switch make a call to a pro and let them fix it for you.

Clogged pathways and Filters

Dishwashers have water and drainage filters that often get clogged with food particles or debris. When this happens the water can’t escape causing it to leave standing water inside.

If the dishwasher is not able to drain the dirty water it will start beeping constantly.


Regularly clean the filters and drainage hose. Use running water to rinse off the excess debris on them.

Also, check the drainage hose for blockage or leaks. If there are leaks, it will drain the water but the debris will not be able to escape and will stay inside the hose.

Dishwasher Beeping Constantly: How to Fix Reed Switch and Sensor Fault

Reed sensors detect obstructions in the dishwasher’s spray arms and door. If it detects anything blocking the door it will make the dishwasher start beeping.


A faulty reed switch will send a false signal making the dishwasher’s control panel think that something is obstructing the arms or the door when it is not.

Here is how to check for reed switch issues:

  1. Set a multimeter to resistance and put the crocodile clamps on the reed blades.
  2. Take a strong magnet and slowly pass it around the reed switch.
  3. If the multimeter starts beeping, then the switch is fine. If it does not make any noise, then you will have to replace the switch.

Get a reed switch from Amazon and follow this video on how to replace a reed switch. It should stop the beeping. Also, make sure the door has a strong magnetic seal so the reed sensor does not send false signals.
