Error code E1 in the Crohn dishwasher
The code base of the self-diagnosis system begins with this error. Error E1 in the Krona dishwasher also occupies a special place because it occurs very often, almost more often than others. That is why we decided to pay closer attention to it and devote an entire article to this code.
Why did the error appear?
It is very difficult to understand the reason why a particular fault code appeared. In this case, too, we will first decipher the error, and only then begin to delve into the possible reasons for its occurrence. It looks like this: The Krona dishwasher control module gives a command to add water to the system and begins the countdown. In a normal situation, the dishwasher must draw a certain amount of water within the allotted time; if it does not do this, the electronics detect an error and display code E1. It remains to be understood why the machine did not take in enough water?
- Because a blockage has formed in the inlet hose or, most likely, in the flow filter.
- The intake valve does not open well.
- The inlet hose has leaked and the leakage protection system has activated.
Each of these reasons may well become your “headache,” but blockages are most likely to occur. In general, the quality of tap water leaves much to be desired. It constantly contains either sand or pieces of rust. All this may well cause a blockage, so we need to start by checking the blockages.
The inlet hose and flow filter are not protected in any way from lime deposits carried with tap water. Draw conclusions.
In-line filter clogged
Even a housewife who is far from technology can check her Krona dishwasher. What to do? First, you need to shut off the flow of water into the machine. If there is a tee valve between the inlet hose and the supply line, you can turn off the water there; if there is no valve, you will have to turn off the entire riser with cold water. Secondly, you need to disconnect the inlet hose from the tee and from the inlet valve, take the hose to the bathroom and have a good look at it there. You can detect a blockage, although, as a rule, there is none in the hose.
Temporarily putting the hose aside, we turn our attention to the inlet valve fitting from which we just disconnected the hose. There is a flow filter inside the fitting that needs to be pulled out and checked. Perhaps it was the one that got clogged, then a thorough cleaning will quickly return the dishwasher to service. If the filter and hose are clean, you need to check the leakage protection system.
Leakage protection triggered
Krona equipment has unusual inlet hoses. This Aquastop hoses for dishwasher. They have a double shell, and when the inner shell breaks, the system blocks the flow of water into the machine, protecting the room from flooding. So, you need to check that this very protection does not work. Otherwise, you will have to remove the old hose and buy a new one, since after operation, hoses with Aquastop cannot be reused.
Let's inspect the housing at the base of the inlet hose of the Krona machine. There should be a small indicator that notifies the user when the system is activated. If the indicator is on, you can safely change the hose, after which the machine will work as usual.
Intake valve problems
If the inlet hose is fine, we have to assume that the inlet valve has failed.Moreover, it was not completely broken, otherwise the control module would not have been able to detect it and would have issued another error, but we have E1, which means the problem is in the mechanics of the valve. How to fix such an annoying problem?
- You need to remove the intake valve.
- Carefully inspect its mechanism and remove all suspicious specks.
- You need to check how the damper moves. If it jams for no apparent reason, repair may not be possible; the valve must be replaced.
Just in case, you can check the resistance of the valve coil, but most likely everything will be fine there. In case of error E1, the valve electrics usually remain on the sidelines. After replacing the valve, check how the dishwasher will work. Most likely, after this the error will leave the display of the Crohn machine.
So, we have deciphered the E1 error code in the Krona dishwasher. We not only identified the range of possible breakdowns, but also told how to fix these breakdowns. Let's hope you will be able to increase your self-esteem by repairing your “home assistant” with your own hands. But even if difficulties arise, you can always contact our specialists. Good luck!

My machine took in water, showed error e1 and drained the water. The error is related to the water supply. It turned out that the reed sensor was oxidized. The machine did not understand how much water it filled. After cleaning the problem went away.
How did you clean it, where is this sensor located and what does it look like? We have the same problem!
