Error E4 on a Korting dishwasher

Dishwasher error codes can be annoying, particularly if they interfere with your daily schedule. You undoubtedly want to know what the E4 error on your Korting dishwasher means and how to resolve it.

This error typically indicates a water problem, which can be anything from a small fix to a more serious issue requiring more care. Don’t worry, though; the first step to getting your dishwasher operating again is figuring out what’s causing the E4 code.

First, let"s find out what this code is

Error E4 alerts the homemaker that the Aquastop protective mechanism has been triggered because liquid has got inside the appliance’s tray. In this situation, the Korting dishwasher will immediately activate the drain pump to force water out of the tray.

Your "home assistant" will report a malfunction with a flashing indicator on the control panel that resembles a glass or shot glass if it lacks a display and the device is unable to display the error code. Additionally, some Korting brand devices with displays may display error E04 instead of E04.

E4 was provoked by something simple

Occasionally, a less serious issue that has nothing to do with the device’s internal components failing can be the hidden cause of the E4 error. Should this truly be the case, you can resolve the issue on your own without contacting a technician. How should I handle this?

• Perhaps the communications have leaked, on which the operability of household appliances directly depends. It is worth examining the inlet hose of the Korting dishwasher. In addition, you can check the tray of the dishwasher, probably water accidentally leaked into it after the liquid spilled on the countertop, and then penetrated into the PMM through the cracks.
• Perhaps a blockage has formed in the filter of the machine, which usually leads to a deterioration in water circulation during operation, as well as to an overflow of the washing chamber, due to which liquid penetrates into the tray, causing the Aquastop to be triggered. If the E4 error appeared because of this, then it will be enough to clean the filters, which is described in detail in the Korting dishwasher user manual.
• Probably, household chemicals for hand washing dishes were used. It is prohibited to do this, because if a regular detergent, such as Fairy gel, gets inside the dishwasher, it will provoke abundant foam formation in the washing chamber. Because of this, the foam along with the water will get into the tray, which will be followed by activation of the Aquastop protection and error E4. If this is the case, then in order to eliminate the consequences, you will have to urgently disconnect the equipment from the network and let it stand for a couple of days until it dries.

You should never use common household chemicals during automatic dishwashing because increased foaming can cause damage to the dishwasher control unit and disable it. This makes it extremely dangerous.

• Poor-quality detergents produced without observing safety precautions could have been used. In this case, increased foam formation and fluid entering the tray may also occur.
• There is a water overflow directly from the sewer. Most often, the Korting dishwasher drain is connected to the sink siphon, which gets clogged from time to time. If this happens, then instead of draining the waste liquid into the sewer, the water will return back through the drain hose. In this case, an overflow will occur, Aquastop will be triggered and the machine will report an error E It is easy to fix the situation – you need to remove the blockage from the siphon, and in the future, install a check valve on the dishwasher drain.

After taking out the Korting dishwasher to guarantee free access, the simplest method to get rid of extra water is with a dry cloth. Alternately, you can tilt the device back to empty the water from the tray. Lastly, if the machine needs to be used once a day or more, you can simply wait a few days for the liquid to evaporate on its own. However, this is not a viable option.

The tightness of the joints has been broken

The weakening of the connecting clamps and the increased wear of the oil and sealing laying seals may be the cause of the pallet overflow. Furthermore, solid food residues that harm the "home assistant’s" pipes and hoses are frequently the root of the issue. Less frequently, the described affects the inlet hoses. Usually, it affects the drain hoses and the hoses that circulate water.

Drying out of the seal rings on the drain pump is another common problem with Korting dishwashers. In such a scenario, the liquid will exit the location where the pump and drain system are connected.

In order to address the issue, you will need to disassemble the machine to a certain extent and thoroughly inspect every joint for potential leaks. To remove the possibility of the error code E4 "popping up" once more, you will need to replace any damaged seals, clamps, and other components.

The leak sensor is broken

Additionally, the housewife might be disturbed by the malfunction since the Aquastop sensor itself broke and could hang in the position that stops the leak. This typically occurs when the microswitch, a tiny, delicate component that can block even dust and tiny fat particles, fails.

You can attempt to gently clean it of dirt to reset its position, but this is frequently a time-consuming task. Replacing the microswitch—for which you will need to remove the tray and install a new part—is far simpler and more efficient.

Error E4 on a Korting dishwasher typically denotes a drainage problem with the water, which is frequently brought on by a blocked filter, a kinked hose, or a malfunctioning drain pump. To fix it, make sure the hose is positioned correctly, look for obstructions, and look for debris inside the pump. Resolving these typical problems can frequently fix the error and restore your dishwasher’s smooth operation.

Problem with the seal

The rubber seal on the washing chamber door is another frequently occurring issue that needs to be examined. This element may dry out and lose its ability to insulate during prolonged use. The Aquastop sensor will activate if this occurs because water will seep through the door and into the tray, as well as onto the floor.

The malfunction can be easily fixed by simply replacing the damaged rubber element with a new one that you purchase and install.

When a Korting dishwasher displays error E4, it typically indicates a problem with the water drainage system. A blockage in the drain hose, filter, or pump itself could be the source of this. Often, the issue can be fixed by inspecting these components and removing any debris.

It might be essential to check the pump for damage or malfunction if the error continues. In certain instances, the problem might be associated with the sensor or control board of the dishwasher, necessitating expert assistance to resolve.
