Error code E1 in the Crohn dishwasher

With this error, the code base of the self-diagnosis system begins. 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 one or another trouble code appeared. So in this case, we first decrypt the error, and only then we begin to delve into the possible reasons for its occurrence. Everything looks as follows. The Crohn dishwasher control module issues a command to draw water into the system and starts the countdown. In a normal situation, in the allotted time, the dishwasher should draw a certain amount of water, if it does not, the electronics fix the error and display the code E1. It remains to be understood why the machine did not get enough water?

1. Because in the inlet hose or, most likely, a blockage has formed in the flow filter.
2. The inlet valve opens poorly.
3. The inlet hose leaked and the leakage protection system tripped.

Each of these reasons may well become exactly your “headache,” however, blockages are most likely to occur. In general, the quality of tap water leaves much to be desired. It constantly appears in the sand, then scraps of rust. All this may well become a cause of blockage, so you should start by checking for blockages.

The inlet hose and the flow filter are not protected in any way from the calcareous deposits that tap water carries with it. Draw conclusions.

Flow filter clogging

Even the mistress, far from equipment, can check her dishwasher Krona. What to do? First, you need to block the flow of water into the machine. If there is a tee tap between the inlet hose and the inlet, you can shut off the water there, if there is no tap, you will have to block 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 examine it thoroughly there. A blockage can be detected, although it usually does not occur in a hose.

Temporarily putting the hose aside, we pay attention to the inlet valve fitting, from which we just disconnected the hose. Inside the fitting there is a flow filter that needs to be pulled out and checked. Perhaps it was he who was clogged, then thorough cleaning will quickly return the dishwasher to service. In the event that the filter with the hose is clean, the leakage protection system must be checked.

Leakage protection triggered

The Krona technique has unusual inlet hoses. it 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 the flood. So, you need to check that this protection does not work. Otherwise, you will have to remove the old hose and buy a new one, since after working, the hoses with Aquastop cannot be reused.

We examine the housing at the base of the inlet hose of the Kron machine. There should be a small indicator that notifies the user about the operation of the system. 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 in order, it must be assumed that the intake valve is out of order. Moreover, it did not break down completely, otherwise the control module could not detect it and give another error, but we have E1, which means that the problem is in the valve mechanics. How to fix such an annoying problem?

1. It is necessary to remove the inlet valve.
2. Carefully inspect its mechanism and remove all suspicious specks.
3. You need to check how the shutter moves. If it gets stuck for no apparent reason, repair may not be possible; the valve must be changed.

Just in case, you can check the resistance of the valve coil, but most likely everything will be fine there. Valve electrical normally remains aloof with error E1. Having replaced the valve, check how the dishwasher will work. Most likely, after that the error will leave the display of the Crohn's typewriter.

So, we decoded the error code E1 in the Crohn dishwasher. We not only determined the circle of possible breakdowns, but also told how to fix these breakdowns. Hopefully, you will be able to increase your self-esteem by repairing your “home assistant” yourself. But even if difficulties arise, you can always turn to our masters. Good luck
