Error E24 for a Bosch dishwasher
Housewives are not overjoyed with dishwashers, because they now have free time for their loved ones. However, if some error appears on the display, for example E24, and the machine stops washing, then panic begins, what to do? But there is no need to panic, it is better to mobilize your strength and knowledge to find the problem, and we will try to help you with this.
Error interpretation
The explanation of all Bosch dishwasher errors must be indicated in the instructions. However, decryption alone may not be enough; you need to know how to fix it yourself. Or maybe the machine is so faulty that only a mechanic can help. This is exactly the case with error E24.
Fault code E24 means that there is a problem in draining the water; the manufacturer indicates the cause is a kinked drain hose or a blockage. It would seem that everything is very simple, straighten the hose, clean it and that’s it. But that was not the case; dishwasher users who encountered the E24 error claim that blockages have nothing to do with it.
Most likely, they are right, because judge for yourself what kind of bend in the hose we can talk about if the machine is installed correctly and you do not touch the hose. Secondly, most often error E24, according to people, occurs at the very beginning of the cycle, about 1.5-2 minutes after switching on, when the dishwasher did not even have time to draw water, let alone start draining it. Therefore, it is very strange that the instructions write that error E24 informs about a faulty drain.
If we think logically, then in our opinion, in the case of error E24, the following reasons suggest themselves:
- there is a malfunction of one of the sensors, we have to figure out which one;
- drain pump malfunction;
- There was an error in the software of the control unit.
There are cases when error E 24 alternates with error E 22; how to eliminate it is described in the article Error E22 for a Bosch dishwasher.
Basic solutions
Since the manufacturer means by error E24 a problem with draining water, then let’s first figure out how to remove blockages in the drain system.
We think you won’t have any problems with how to clean the drain filter, because you need to do it regularly. The filter is located at the bottom of the dishwasher and can be removed quite easily. Using a cable and a brush, you need to clean the drain hose. In addition, you can remove the plastic plug under the filter, which will provide access to the drain pump gear. All debris must be inspected and removed. Very often, fruit seeds, such as lemons or oranges, get clogged under the filter, resulting in an error E24.
Important! There may be a clog in the joint between the dishwasher drain hose and the sewer outlet. It also needs to be cleaned.
Let's inspect the pump
The pump itself can become clogged, as a result of which it stops draining water and error E24 appears. To get to the pump in a Bosch dishwasher, you need:
- turn the car upside down;
- unscrew the back cover and side panels (if the machine is not built-in);
- unscrew the lower front bar, and under it another bar that holds the bottom of the case;
- remove the plastic holders on the sides of the machine;
- remove the bottom, after which access to the “insides” of the machine will open;
- a large plastic case with outlets for pipes is a flow-through heating element; there is a pump on the side; you need to turn the pump half a turn clockwise and pull it to the side;
Do not forget to first disconnect the wires and sensors from it.
- now inspect the impeller, there may be hair and threads wound on it, they need to be removed, it is best to pull out the shaft itself;
- After the entire procedure, reassemble the machine in the reverse order and run the wash to check for error E 24.
Tips from forum members
All of the above methods for troubleshooting problems associated with the appearance of error E 24 may not help. Having studied a large number of forums on this topic, we decided to offer a few more tips for troubleshooting this problem. For some, fault code E 24 in a Bosch dishwasher does not cause problems, and after blowing out the drain hose with a washing vacuum cleaner, the problem is eliminated.
One user, in a long struggle with the error, found the cause in the drain pump. It turned out that when it is turned on, the impeller refuses to rotate, and therefore the pump does not pump water. The problem is that the rotor is completely stuck to the walls of the hub or rotates, but is difficult. To solve this problem, you need to clean the walls of the bushing, the rotor itself and lubricate the bushing inside.
Some users write that error E 24 in a Bosch dishwasher can be reset by simply turning the machine on and off. However, we will not recommend this method of eliminating the fault code and will not describe it. Let's explain why - resetting error E 24 will not eliminate the cause itself, but can only force the dishwasher to work at maximum power, which will ultimately lead to even bigger problems.
Error E 24, which appears almost immediately after turning on the machine, can be eliminated after opening the machine door. Here's what users suggest:
- turn on the dishwasher;
- wait about a minute while the pump is running;
- We wait for a click and a noise reminiscent of water filling;
- After about 30 seconds, open the dishwasher door;
It is important to open the door at the right time.
- close the door and wait for the machine to complete the wash cycle.
According to users, the machine works fine, but constantly starting it this way is annoying. After diagnosing error E 24, some solved the problem by rearranging the magnet in the door sensor, which controls whether it is closed or not. Perhaps this happens, although to be honest it raises doubts, after all, error E 24 should be associated with the drain, and not with the door.
But we still found a rational way to eliminate the E 24 code in Bosch machines on the forums. It consists of the following:
- it is necessary to open the right housing cover and remove the seal;
- under the seal, you will see a plastic container, at the bottom of which there are tubes, as shown in the photo, they may be clogged;
- if the pipes are easily disconnected (it all depends on the Bosch dishwasher model), then remove them and clean them with a washing vacuum cleaner, while simultaneously pouring water into the drain hose.
We hope that the photo will help you, at least, understand where to look for the cause of the malfunction that generates error E 24. If none of the methods helped you, then you will have to look for a very good technician who will help you find the cause and correct the error. By the way, only a master can check the functionality of the controller; maybe the reason lies in it, since it does not recognize signals correctly.
In conclusion, we note that dealing with any error in a Bosch dishwasher on your own may not be so easy. It is best to be patient and understand the dishwasher. And by disassembling it, you will have a better chance of finding the cause of error E 24, good luck with the repair!

I took out this E24, and it’s been yelling all night like I’m broken - fix me, until the problem is solved, we’ll continue to monitor it.
Damn, it’s incredible, but the 30-second method helped! This Bosch has already bullied me... I didn’t expect this from them!
I’ve been using this method (30 seconds) for two years now! Enough!!!
The mistake made me nervous. I started from the stove... washed and cleaned all the pipes and outlets leading to the drain, including the receiving filters and the sump. I filled in the PMM cleaner. And lo and behold! Everything worked as before. You can't fool Bosch, you need to clean it more often.
Guys, it's simple. You buy a decongestant and pour it into the machine. Then 3-4 rinses and no error.
At the moment, a regular plunger helped. I pulled a couple of peppercorns out of the filter. Next, I’m thinking of using a congestion decongestant.
Guys, you won't believe it. The machine worked for 3 years after installation. Today I issued E 24.I moved it away from the wall and what was my surprise, how did it even drain the water? The reason is a heavily compressed hose. We tried very hard to push it as close to the wall as possible!
I cleaned and washed the filter inside and everything worked great :)
And nothing about a fairly common cause of this error. The brains do not receive the “tank is empty” signal. Where does it come from? Who knows, he will understand where to go :)
It gives me this immediately after installation. Everything is connected fine.
