Error code E1 in a Krona dishwasher
This error is the starting point of the self-diagnostic system's codebase. The E1 error in the Krona dishwasher is particularly noteworthy because it occurs very frequently, perhaps more frequently than any other error. That's why we decided to take a closer look at it and dedicate an entire article to this code.
Why did the error occur?
Understanding the reason for a particular error code is very difficult. So, in this case, we'll first decode the error and then begin digging into the possible causes. It all works like this: The Krona dishwasher's control module commands the system to fill with water and begins the countdown. In a normal situation, the dishwasher should draw a certain amount of water within the allotted time; if it does not do this, the electronics record an error and display the E1 code. It remains to be seen why the machine did not collect enough water?
- Because there is a blockage in the inlet hose or, most likely, in the flow filter.
- The inlet valve does not open well.
- The inlet hose had a leak and the leak protection system was activated.
Each of these causes could very well be your specific headache, but the most likely is clogs. Generally, the quality of tap water leaves much to be desired. Sand and rust particles are constantly appearing in it. All of these could easily cause a clog, so checking for clogs is the first step.
The inlet hose and flow-through filter are not protected from limescale deposits in tap water. Draw your own conclusions.
Clogged flow filter
Even a homemaker with little technical experience can check their Krona dishwasher. What should you do? First, shut off the water supply to the machine. If there's a tee between the inlet hose and the water supply, you can shut it off there. If there's no tee, you'll have to shut off the entire cold water supply. Second, disconnect the inlet hose from the tee and the inlet valve, take the hose to the bathroom, and inspect it thoroughly. You might find a blockage, although it's usually not in the hose itself.
Temporarily setting the hose aside, we turn our attention to the inlet valve fitting from which we just disconnected the hose. Inside the fitting is a flow-through filter that needs to be removed and inspected. It's possible that this filter is clogged, in which case a thorough cleaning will quickly restore the dishwasher to working order. If the filter and hose are clean, the leak protection system needs to be checked.
Leak protection activation
Krona equipment has unusual intake hoses. This Aquastop dishwasher hosesThey have a double liner, and when the inner liner ruptures, the system blocks the water supply to the machine, protecting the room from flooding. So, you need to check to make sure this protection hasn't been triggered. Otherwise, you'll have to remove the old hose and buy a new one, as hoses with Aquastop cannot be reused once they've been triggered.
Let's inspect the housing at the base of the Krona washing machine's inlet hose. There should be a small indicator there that alerts 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.
Problems with the intake valve
If the inlet hose is fine, we have to assume the inlet valve is faulty. It's not completely broken, otherwise the control module wouldn't have detected it and would have returned a different error. But with E1, the problem lies in the valve mechanics. How can we fix such an annoying problem?
- The inlet valve needs to be removed.
- Carefully inspect its mechanism and remove any suspicious debris.
- You need to check how the valve moves. If it jams for no apparent reason, repair may be impossible; the valve will need to be replaced.
To be on the safe side, you can check the resistance of the valve coil, but most likely everything will be fine. The valve's electrical system is usually unaffected by the E1 error. After replacing the valve, check how the dishwasher operates. Most likely, the error will disappear from the Krona display after this.
So, we've deciphered the E1 error code in your Krona dishwasher. We've not only identified the range of possible faults, but also explained how to fix them. We hope you'll boost your self-esteem by repairing your "home helper" yourself. But even if you encounter any difficulties, you can always contact our technicians. Good luck!

My washing machine was filling with water, displaying the e1 error, and then draining the water. The error was related to the water supply. It turned out to be a oxidized reed switch. The machine wasn't registering how much water it had added. 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!
