Before You Start:

As soon as you encounter this error message you first need to try a few simple techniques to get along with this error before moving on to any of the detailed fixes mentioned below. Some of the basic tips and tricks which you need to try beforehand are listed below:

  1. Turn “ON” the dishwasher and then wait for a couple of minutes. As soon as you hear the sound of filling open the front door for some time as this error might be occurring because of some malfunctioning of the door and not due to the drain system failure. Then close it again after one minute and see if the problem gets settled.
  2. If you have a doubt that the drain pump is not working properly you need to check the “Rotating Impellers” and “Rotors” since these parts require frequent lubrication.
  3. Another absolute reason for the occurrence of this error might be the clogging of the “Drain Pump” because of some leftover food, broken glass, thread, or hair stuck to the impeller. This will, in turn, result in stopping the drain water, therefore you need to clear this blockage as well in order to get rid of the error.
  4. Some users also state that the machine works perfectly fine but you aren’t able to use it in this manner every other day. It may work for some people but it isn’t the case for everyone. A lot many users have reported this one to be the most perfect solution as Bosch itself also states that the problem occurs mainly due to the drain system failure.
  5. Also, check the “Valves” of your drain system which must lie in their proper place, and the filters must also be unplugged. Secondly, check to see if the “Check Valve” (normally in white color) lies in its proper place near the sidewall at the bottom of the dishwasher tub. If it is kept in the proper place then move on to the next check mentioned below.
  6. Another potential check, in this case, is that you must hear a “Humming” sound upon pressing the “Cancel” button from the main menu. If there isn’t any sound produced it means some sort of problem exists with the drain pump and most probably it’s because of the “Low Power” of the drain pump. In this case, you might need to check if the power of the drain pump is complete “120V”.

Rectifying the bosch error code e24:

Solution 1: Check Dishwasher Inlet Hose

If the inlet hose which is meant to move water in and out of the dishwasher gets faulty or damaged it can, in turn, lead to the occurrence of this error. Therefore, as a first check, you need to confirm if the water hose is working fine and if not instantly resolve and adjust the inlet valve problem in order to get rid of the error.

Solution 2: Check Siphon Connection

You also need to ensure that the siphon connection of your dishwasher is sealed as if it gets broken the water will flow back to the bottom of your dishwasher and in turn, it can also be a cause of such error.

Solution 3: Check For Kinked Hoses

You certainly also need to check for any sort of kinks in the drain hose as it is likely to prevent the dishwasher from draining water in turn causing this error. So, it’s a necessary check before moving on to any other detailed fixes. You must also keep in mind that a high loop is required on the dishwasher drain to prevent any sort of faults. If the drain hose is disconnected with the air gap it means that it might be configured with the high loop which will eventually lead to the blockage of wastewater back into the dishwasher hence preventing this error. This should ensure that the Bosch Dishwasher works properly.

Solution 4: Clean the Dishwasher Filter

The Bosch dishwasher constitutes of a filter located at the bottom of the dishwasher and if it gets dirty it will lead to this error so make sure you try cleaning it out using warm water and then fix it back. You can locate the filter by removing the bottom dish rack and then detaching it from the dishwasher. Or you can also consult the user manual for filter removal instructions.

After cleaning the filter thoroughly then ensure if the error got removed. If the error still exists you might also need to clean the dishwasher thoroughly by using any detergent or cleaning solution. Bosch itself also manufactures a dishwasher cleaner that can be purchased and used for cleaning purposes or otherwise, you can also make a cleaning solution at home using a couple of easily available products such as white vinegar solution mixed with baking soda that helps effectively in clearing up the blockages. If you want to clear the blockage using vinegar and baking soda solution here are some of the detailed steps involved in it:

  1. First, you need to grab a “Dishwasher-Safe” bowl and then pour distilled “White Vinegar” in it.
  2. Then place the bowl on the “Top Rack” of the dishwasher safely.
    Note: Make sure the dishwasher must be empty and should not contain any dishes or detergent.
  3. Now run a “Normal Cycle” of the dishwasher and once done move on to the next step.
  4. Finally, take a cup of “Baking Soda”, sprinkle it into the dishwasher, and run a short “Hot Cycle”.
  5. Completing this procedure will make your dishwasher crystal clear and will remove any sort of blockages.
  6. Verify that the Bosch Dishwasher Error Code E24 is fixed after this.

Solution 5: Fix the Drain Pump Cover

Check out the pump cover beneath the filter and make sure it isn’t too loose. If you are unable to locate it yourself simply head to the user manual from here and you’ll get to know each of the relevant details. After fixing the cover properly now see if the error gets disappeared or not. Also, the drain pump may also get clogged sometimes leading to blockages so it’s necessary that you check for it as well but make sure to cover your hands properly by wearing protective gloves as the pump housing may contain several sharp objects.

You also need to make sure if the pump’s impeller turns freely, if you face trouble turning it, it means that the drain pump is defective and needs to be replaced. Another way to check if the drain pump is working or not is by lifting up the float which is located near the dishwasher filter. If it is working fine the dishwasher should be able to activate the drain pump upon lifting up the float and vice versa. But this needs to be done very carefully as one’s hands may get injured while lifting up the float. So, it’s better to keep your hands out of the drain pump area while doing so. After fixing it, check if the Bosch Dishwasher Error Code E24 is now fixed.

Solution 6: Clean the Air Gap / Garbage Disposal

The dishwasher is designed so that the drain hose connects to either an air gap or garbage disposal / S trap below the sink. Upon removing the drain hose you will easily get to know about the blockage that is causing this error and as a remedy, you can try cleaning the air gap, garbage disposal / S trap.

Solution 7: Remove Plug From Disposer Drain Connection

One thing you need to make sure of is that if the dishwasher drain hose is connected to the garbage disposals drain connection you should ensure that the plug is detached from the disposers dishwasher drain connection. If not, then remove the plug manually and check to see if the error code e24 got resolved.

Solution 8: Relocate the Dishwasher

One more important thing is that if the drain system is working perfectly fine and you aren’t able to find any bugs in it, it means that some other sort of problem exists with it. In order to find it out, you must dislocate the dishwasher from its original position (the cabinet where it is installed) and then inspect the matter in more detail. After removing the dishwasher from the cabinet locate the main control on the lower right corner, then from the right panel open up the seal. Keep in mind that while doing this the main supply to the dishwasher should be turned “OFF”. On removing the sealing you will get to see “Six” wires (three grey and three black). Remove the connectors attached to the wires and then you will be seeing “89” ohms on the grey wire going directly into the drain pump and “14” ohms on the black wire going to the circulation pump.

After looking into both of these things replace the main control. You will also see a plastic container inside having tubes at the bottom which get clogged often due to some sort of waste material. Detach these branch pipes carefully, clean them thoroughly and then place them back properly. Check to see if this has fixed the Bosch Dishwasher Error Code E24 issue.

Solution 9: Check For A Faulty Drain Hose / Drain Pump

If none of the remedies above prove to be effective in removing the error then it is quite probable that either the dishwasher drain hose or drain pump is defective. It is possible that the drain hose might have been blocked or the drain pump might have become faulty thus displaying this error. So take out the drain hose and clean it thoroughly to clear any blockages.

In order to access the drain hose and drain pump firstly, you need to disconnect the power supply from the dishwasher and turn “OFF” the water supply. Then take out all of the screws from the kick panel located in the top right corner. Now in order to check the drain hose, you first need to locate it, it must be connected to the drain pump. Then disconnect the drain hose from the drain pump by removing the wire clamps using a cutter and try to clear out the blockages using drain cleaner sticks. You can also detach the drain hose from the sink and then clean it by passing hot water to dissolve any needed particles/soap build-up.

You can also use a drain snake for this purpose and after cleaning it thoroughly attach the drain hose back to the dishwasher carefully. As a second check, you will need to examine if the drain pump is working fine or not. The drain pump won’t be able to drain the water properly mainly in two scenarios when either the pump motor has failed or if some obstacle is blocking it anyhow. Therefore it is necessary to check the pump motor for any obstructions and also that it turns freely. If the impeller does not turn freely it means that the drain pump needs to be replaced. Also, a continuity test can be done on the drain pump using the multimeter by keeping it on the ohms setting, and if the motor tests negative it means that it needs to be replaced.

Note: If doing so also doesn’t help you anyway it means that the control board may be defective and in such a case you will need to contact any trained professional or report your problem to the customer support service.
