Your dishwasher allows you to wash your dishes after you’ve given them a rub down with water and removed all the extra food. Dishwashers use water at a high press and detergent to get rid of the extra foods and grease that’s remaining on your plate. You can load your dishwasher will all of your dishes, press a few buttons, and it’ll start working its magic. Usually, dishwashers work fine, but sometimes they can experience problems.
Having your Bosch dishwasher malfunction is a massive inconvenience, and this can force you to wash your dishes with your hands again. If your Bosch dishwasher is making a beeping sound and you don’t know why you can look at the reasons why. There are a few reasons why this can happen and there are some things you can do to fix it.
Why Is My Bosch Dishwasher Beeping?
If your Bosch dishwasher is beeping and the sound doesn’t seem to be going away, you can look at a few reasons why and use them to fix the problem. Chances are that you’re using something incorrectly, or a certain part of the dishwasher needs replacing. Bosch dishwashers come with an inbuilt electronic sensor that makes beeping sounds or causes the lights to start blinking to cause the user that something is wrong.
The beeping noise that you may hear 3 or 5 times is synonymous with the plus 44/46 dba model and you’ll commonly hear it when the dishwasher isn’t starting. The beeping noise might also happen mid-cycle which will indicate that a problem has occurred mid-cycle.
You’ll also notice that your Bosch dishwasher will be beeping with no error codes so you won’t be able to diagnose the noise quickly and why it’s happening. With error codes, you’ll be able to look up what it means, but since you’re not given one, trying to find out why it’s been is going to be an uphill battle.
You may also notice that your Bosch dishwasher won’t start and just beeps. If your dishwasher is unable to start but you notice that it beeps, then there’s a problem that’s causing it not to start which is triggering the beeping noise. Getting to the root of the problem that’s causing your dishwasher not to start might stop the beeping noise.

Warning: Dishwashers are electronic devices and therefore, you need to follow some guidelines when you’re trying to repair your dishwasher. If you think that there’s an electrical problem with your dishwasher, then the best option would be to call a professional to get the job done rather than do it yourself. Electrical components that malfunction in your dishwasher are usually located in the door or on the based and they can be accessed via an inspection panel or by removing the inner door.
1. The Cycle Is Done
A lot of Bosch dishwashers are fitted with alarms that are as loud as possible when the washing cycle is done. When you’ve finished washing your load, if your dishwasher continues to beep, then you’ll need to open the door and wait for it to stop. There’s an electronic device that triggers an alarm when the washing cycle has been done. The alarm then needs to alert the dishwasher user that the cycle is done, hence the beeping sound. This is called the completion signal and you can adjust the tone and volume.
2. Opening the Door During Cycle
If you opened your dishwasher door whilst the cycle was still completing, then this could be why it started beeping. In this case, you’ll need to close the door and wait for the cycle to complete. If the cycle was unable to complete, then you’ll need to turn your dishwasher off them to restart the cycle.
3. No Detergent
If you forgot to add detergent, this could be why the dishwasher started to beep. Dishwashers require detergent in order to wash dishes properly and break down the grease. If no detergent was broken down with water rushing out the inlet valve, then this might trigger your dishwasher to start beeping.
4. Broken Flow Meter
If the flow meter in your dishwasher is broken, this can trigger a beeping sound. The flow meter is a sensor that measures the flow and amount of water that your dishwasher is filled with. If your flow meter is broken, you’ll need to get it replaced and it’s best to get a professional to do this.
5. Broken Reed Sensor
Your reed sensors are the things that protect the dishwasher’s spray arms. The dishwasher’s arms spray hot water and stream under a high pressure to all of the dishes. If a dish is improperly positioned in the dishwasher, this can block the rotation of the spray arm. If the reed sensor is broken, you’ll need to get it replaced or checked out by a professional.
6. Dishwasher Beeping with Lights
If your dishwasher is beeping whilst the lights are bling, this can indicate the anti-flood device activation. This means that water has been detected in the dishwasher’s casing by sensors and has stopped the dishwasher from working. This is to prevent the water from leaking all over the floor.
7. Power Outage
If there was a power outage, then this can cause the dishwasher to start blinking. To fix this, you’ll need to unplug the dishwasher from the power or shut off the breaker to the dishwasher for 1 minute. Once you turn the dishwasher on again, the beeping noise should have stopped, and you can start your washing cycle again.
8. Dishwasher Not Draining
If you’re hearing the beeping sound and you notice that your Bosch dishwasher isn’t draining, then there might be a problem with the dishwasher drainage systems. To check this before calling in a professional, you can remove and clean the filters. If they’re damaged, then you can replace them. You should find them at the bottom of the dishwasher to remove them, you can twist and pull.
Another thing to check if your dishwasher isn’t draining if it’s connected to the waste hose. If the waste hose is being obstructed or it’s being pinched, then water won’t be able to drain properly, and this can cause a beeping sound.
If there’s a blockage in your sink, then this can stop your Bosch dishwasher from being drained. If the dishwasher’s water pipe is connected to the sink, then you’ll need to get a professional to check it out. If there are large pieces of food that go through the waste pipe, it’ll need to be removed. Another thing that can get in here is grease. Whilst the grease is hot, it gets into the waste pipe, then once it hardens, it can get stuck in here for good.
If your Bosch drain pump is blocked, this can stop the dishwasher from draining. Over time, food can get stuck in the drain pump. You can get a wet-dry vacuum tool to get rid of this or you can scoop it out with your hands. If you don’t know how to access the drain pump, then you’ll need to get a professional to check it out.
9. Cycle Selector is Stuck
The cycle selector on your Bosch dishwasher is what you use to choose the cycle that you want to start on. The dishwasher uses what the cycle selector is on to start the cycle. If the dishwasher hasn’t processed the cycle selector option you’ve chosen, then your dishwasher won’t be able to start and it’ll start beeping. You can try to choose a different cycle and hope that the dishwasher starts which will stop the beeping sound. Sometimes dishwashers don’t process the options chosen and it can remain stuck which can cause the beeping noise to start. Choosing a different cycle might trigger it to start.
10. Broken Timer
There’s a timer in your dishwasher that controls the cycle by controlling the amount of time power that’s sent to each of the dishwasher components. If the timer is broken, then it can trigger the beeping noise to start because the cycle won’t start. It’s uncommon to find that your dishwashers’ timer is no longer working and it’s also hard to diagnose that they’re malfunctioning but the beeping noise might be your first clue. If the timer doesn’t work properly, then some of your dishwasher’s components won’t get enough power to them, therefore it may not start. To test this, you need to use a multimeter (view on Amazon) to test the resistance.
- Disconnect the dishwasher from the power source.
- Locate the time and remove it. It’s likely that you’ll find it in the control panel behind the lower kick plate.
- Sometimes the timers can have multiple contacts/wires and if this is the case for your Bosch, you need to refer to the wiring diagram in the manual to check which contacts to test.
- Set the multimeter to Rx1000 and touch the probe with the contacts. A good functioning contact should bring back a resistance that between 2000-3500 ohms. This can defer between Bosch models.
11. Faulty Motor
Sometimes your dishwasher can start, fill up with water, then once the cycle is meant to start, it doesn’t start and you hear the beeping noise. If this is what you’ve experienced, chances are that the motor is broken. If you’re familiar with dishwashers, you can try and access the motor. You’ll need to look underneath the pump cover and filter assembly to check if it’s clogged. If it is, this could be causing the beeping noise.
12. Delayed Motor Relay
On some dishwasher models, there’s a motor relay on the main pump motor. The relay provides power to the motor to start windings until the motor is running and has a moving plunger inside that operates some contacts. If the motor relay is damaged and you try and start your dishwasher, it can cause your dishwasher to beep.
