Error E22 on a Bosch dishwasher

error e22Bosch brand dishwasher is quite reliable and breaks infrequently, especially if this machine is of European assembly. However, sometimes this happens, the equipment stops working, and the system error code lights up on the display. The problem is that quite a few encoded errors are embedded in the dishwasher control unit and the first thing the user will need to do is decrypt the code that appears and then take action. In the framework of this story, we will be interested in error e22, let's talk about it in more detail.

System Error Circumstances

In most cases, error e22 on a Bosch dishwasher appears before the end of the washing program. It remains literally 5-7 minutes, the machine first pauses the program or program cycle, and then freezes and gives an e22 error. Sometimes after turning off the brand dishwasher Bosch and its repeated inclusion, it is possible to resume its normal operation, but after 2-3 programs there is a hang again and the error again “pops up” into the display. Sometimes it’s different.

  1. System error e22 on a Bosch dishwasher appears at the beginning of the program or in the middle.
  2. Then the user, trying to solve the problem on his own, turns off the dishwasher, waits for a while, then turns on and starts the washing program again.
  3. The machine begins to wash the dishes, but after 10-15 minutes it freezes and gives another system error e24.
  4. In the future, if you restart the Bosch dishwasher repeatedly, these two system errors may appear alternately or only error e22.

Important! Do not get carried away, suddenly turning off the Bosch dishwasher repeatedly, this can lead to the failure of the control unit, and this is already an expensive repair.

Explanation of the error and possible causes of its occurrence

According to the data recorded in the instructions of several dozen models of Bosch brand dishwashers, error e22 stands for "clogged or littered filters". This means that food debris washed from the plates clogged the filter screen at the bottom of the dishwasher or got into the trash filter and interfere with normal water drainage. Here, as a rule, the devil lies (as he is known in the details). The user reads the instructions, pulls out the basket for dishes, checks the mesh - it is clean, twists the filter, there is also no special dirt.cleaning the filter in the dishwasher

The user can only be perplexed as to how, the error is decrypted, how the filters get clogged, and the filters are clean - what's the matter? In about half the cases, to get to the cause of the e22 error, you need to go deeper into the Bosch dishwasher, because the dirt has accumulated precisely in the bowels of the device. We will tell you more about the progress of troubleshooting in a bit later.

If error e22 is interspersed with error e24, then the reason may be more complicated. In approximately 20% of cases, the masters indicate that the e22 error alternates with the e24 error in the event of a blockage in the drain hose, but more often such a cascade of errors causes a pump problem. On Bosch dishwashers, the pump is much weaker than on washing machines, nevertheless, it can throw such a “fuss” that you will figure it out for a long time, but it still broke in your “home assistant”.

Errors e22 and e24, which paralyze the Bosch dishwasher, can be caused by a string or a piece of green onion feather that has fallen between the impeller and pump sleeve. The reason is banal, and you can fix the problem in ten minutes, unless of course you know how to do it.

Note! If errors e22 and e24 appear alternately when rebooting the Bosch dishwasher, the problem may be that the impeller does not rotate on the drain pump.

We eliminate the causes of the error

For all that, it turns out that there are quite a lot of reasons for the occurrence of the e22 error in Bosch’s “dishwasher” and without getting into the bowels of the machine, it’s impossible to understand exactly what it is. We will not “pull the cat by the tail” and begin to step by step check the elements of the dishwasher, which can potentially give rise to this system error.

  • First, turn off the dishwasher from the mains and turn off the water tap.
  • Open the door and take out baskets for dishes and cutlery trays.
  • From the bottom of the hopper we take out a plastic sprinkler.
  • We unscrew the waste filter and clean it.
  • We remove the filter mesh and clean it.
  • We unscrew the fixing bolts and pull out the nozzle, you also need to check it for blockages.
  • Turn the dishwasher upside down, unscrew the plastic tray holders and start pulling the tray with the units up.
  • In the middle of the pallet is a large plastic unit with outlets for pipes. It contains a heating element, which at the same time would be nice to check. You can read about how this is done in the article. replacing the ten of the dishwasher.
  • A pump is installed on the side of the heating block, it must be unscrewed by first removing the wires.
  • Check how the impeller rotates and if there are any foreign objects on it. If the rotation of the impeller is difficult, remove the rotor from the hub and check.

  • We install the pump in place, after which we check for drainage hose blockages.
  • After that, the “dishwasher” can be collected if you clean all the above items - the e22 error will disappear.

Summing up, we note that as you can see, it is not so difficult to eliminate the cause of the e22 error, it is much more difficult to identify it correctly. But you should not be upset, even in the worst scenario, you can deal with the problem with your own hands in a maximum of 30 minutes, the main thing is to carefully read the article and follow the advice of specialists. Well, of course, do not neglect to read the instructions.
