Error E22 for a Bosch dishwasher
A Bosch brand dishwasher is quite reliable and breaks down infrequently, especially if the machine is built in Europe. However, sometimes this happens, the equipment stops working, and a system error code lights up on the display. The problem is that the dishwasher control unit contains quite a few coded errors, and the first thing the user will need to do is decipher the code that appears, and only then take action. Within the framework of this story, we will be interested in error e22, let's talk about it in more detail.
Circumstances under which the system error occurred
In most cases, error e22 on a Bosch dishwasher appears before the end of the washing program. There are literally 5-7 minutes left, the machine first pauses the program or cycle of programs, and then freezes and displays error e22. Sometimes after unplugging the dishwasher brand Bosch and turning it on again, it is possible to resume its normal operation, but after 2-3 programs it freezes again and the error “pops up” on the display again. Sometimes it's different.
- System error e22 on a Bosch dishwasher appears at the beginning of the program or in the middle.
- Then the user, trying to solve the problem on his own, turns off the dishwasher, waits a while, then turns on and starts the washing program again.
- The machine starts to wash the dishes, but after 10-15 minutes it freezes and displays another system error e24.
- In the future, if you restart the Bosch dishwasher many times, these two system errors may appear alternately or only error e22.
Important! Do not get carried away by suddenly turning off the Bosch dishwasher repeatedly, this can lead to damage to the control unit, and this is an expensive repair.
Explanation of the error and possible reasons for its occurrence
According to the data recorded in the instructions of several dozen models of Bosch dishwashers, error e22 stands for “filters are clogged or dirty”. This means that food debris washed off the plates has clogged the filter mesh at the bottom of the “dishwasher” or has entered the garbage filter and is interfering with the normal drainage of water. This is where, as a rule, the devil lurks (as we know, he is in the details). The user reads the instructions, takes out the dish baskets, checks the mesh - it’s clean, unscrews the filter, there’s not much dirt there either.
The user can only wonder how it is that the error is deciphered, how the filters are clogged, but the filters are clean - what’s the matter? In about half of the cases, to get to the cause of error E22, you need to go deeper into the Bosch dishwasher, because dirt has accumulated in the bowels of the device. We will tell you more about the progress of troubleshooting and troubleshooting a little later.
If error e22 alternates with error e24, then the cause may be more complex. In approximately 20% of cases, technicians indicate that error E22 alternates with error E24 in the event of a blockage in the drain hose, but more often such a cascade of errors is caused by a problem with the pump. On Bosch dishwashers, the pump is much weaker than on washing machines, however, it can throw such a trick that you will spend a long time figuring out what is broken in your “home assistant”.
Errors E22 and E24, which paralyze the operation of the Bosch dishwasher, can be caused by a thread or a piece of a green onion feather that has gotten between the impeller and the pump bushing. The reason is very banal, but you can fix the problem in ten minutes, if, of course, you know how to do it.
For your information! If errors e22 and e24 appear alternately when restarting a Bosch dishwasher, the problem may be that the drain pump impeller does not rotate.
Eliminating the causes of the error
It turns out that there are quite a few reasons why error E22 occurs in a Bosch dishwasher, and without delving into the depths of the machine, it is impossible to understand exactly what’s going on. Let’s not “pull the cat by the tail” and begin to step by step check the elements of the dishwasher that could potentially give rise to this system error.
- First, disconnect the “dishwasher” from the power supply and turn off the water supply tap.
- Open the door and take out the dish baskets and cutlery trays.
- We take out the plastic sprinkler from the bottom of the hopper.
- Unscrew the garbage filter and clean it.
- Remove the filter mesh and clean it.
- We unscrew the fastening bolts and pull out the pipe; you also need to check it for blockages.
- We turn the dishwasher upside down, unscrew the plastic tray holders and begin to pull the tray with the units up.
- In the middle of the tray there is a large plastic unit with outlets for pipes. It contains a heating element, which would also be a good idea to check. You can read about how this is done in the article replacing dishwasher heating element.
- There is a pump installed on the side of the heating block; you need to unscrew it after first removing the wires.
- Check how the impeller rotates and whether there are any foreign objects on it.If the impeller is difficult to rotate, remove the rotor from the bushing and check.
- We install the pump in place, and then check the drain hose for blockages.
- After this, the “dishwasher” can be assembled, if you clean all the above elements, error e22 will disappear.
To summarize, we note that, as you can see, eliminating the cause of error e22 is not so difficult; it is much more difficult to correctly identify it. But you shouldn’t be upset, even in the worst case scenario, you can deal with the problem yourself in a maximum of 30 minutes, the main thing is to carefully read the article and follow the advice of experts. And, of course, do not neglect reading the instructions.

Thank you for the article! What to do if the dishwasher is built-in?
And I have a built-in machine, and it gives the same error, what should I do about it?
It doesn't matter whether it's built-in or not. The algorithm is the same everywhere.
Thanks for the tip
Thank you!!!
Thanks for the advice :) There was no need to turn it over. I simply cleaned the filter.
