You are not alone if your Kuppersberg dishwasher is giving you an Error E2. This problem can be a little confusing, particularly if you don’t know what it means or how to resolve it. Although error codes are intended to assist users in identifying issues with their appliances, they can occasionally be unclear.
Error E2 usually indicates a drainage system issue with the dishwasher. Knowing the cause of this error can help you troubleshoot it more effectively, whether it’s a clogged drain, a malfunctioning pump, or a problem with the water sensor. We’ll go over the typical causes of Error E2 in this post and provide you simple steps to fix it.
You should know more about how to resolve this issue and restore your dishwasher’s functionality by the time you finish reading this guide. Let’s examine the specifics and restore optimal functionality to your appliance.
Cleaning the main filter system
Starting with the most fundamental reasons for the malfunction will always make it easier to remove the error code. By doing so, you can identify the malfunction fast and avoid wasting time disassembling the machinery and inspecting difficult-to-reach areas. As a result, you must first inspect the cleaning filter, which is found in the dishwasher bin beneath the Kuppersberg. The device is next to the liquid spray arm; the dishbasket’s lower basket is right beneath the unit’s cover.
To make your work easier, remove all of the baskets from the washing chamber beforehand.
Food particles and foreign objects that may have remained on dirty dishes before they were loaded into the dishwasher frequently cause the garbage filter to become clogged. In order to avoid mold growth and the development of an unpleasant smell in the chamber, the filter element needs to be cleaned at least once every week. Furthermore, after washing, the cleaning filter clogs, which frequently stops water from draining. How should the filter element be cleaned?
- Disconnect the equipment from all communications.
- Open the door.
- Remove all water from the washing chamber.
- Use a rag or sponge to collect the debris that could have collected around the garbage filter.
- Remove the dust filter cover.
- Wash all the parts of the filter element with a stiff brush, or with a citric acid solution if the dirt cannot be removed.
- Wait until the filter dries, but do not rush to install it back in place, because first you need to clean the drain hole with a mesh filter.
- Remove all debris and dirt from the surface of the drain.
- Remove the parts from the drain and temporarily seal the hole with tape to prevent foreign objects from getting into it.
- Clean the components with a sponge or brush.
Take caution when working with the component to avoid stretching or deforming the rubber seal.
You can also use a citric acid solution or take a table vinegar solution if the dirt is too stubborn for you to remove with your hands.
Error E2 on your Kuppersberg dishwasher typically indicates a problem with the drainage or water supply. This error usually means that the dishwasher is having problems emptying its water or filling it correctly. The problem can be solved by inspecting the drainage pipes, hose connections, and water inlet valve.
Clogged drain hose
The drain hose in a Kuppersberg dishwasher may also give rise to an unpleasant error code E2. In a perfect world, you could just straighten the hose until the internal plug slides out and into the drain, but that’s not likely to happen, so you’ll need to take it apart and give it a wash. How can I accomplish this?
- Disconnect the "home assistant" from all utilities.
- Loosen the clamp to remove the hose from the sink nipple or from the tee tap.
- Move the dishwasher to the center of the room to ensure free access to all sides of the body.
- Place rags or unnecessary towels under the machine, and then lay the device on its side.
- Disconnect the filling hose from the Kuppersberg dishwasher, having first loosened the clamp.
- Thoroughly rinse the hose with a powerful stream of running water, or soak the hose in a basin with a solution of citric acid if the plug does not give in.
It is still necessary to verify whether the error code has "gone away" after the modifications have been made. In order to accomplish this, you must first initiate an idle working cycle devoid of dishes and closely observe how the device functions. Proceed to the next check item if you were unable to reset the E2 error.
Testing and replacing the water level sensor
To check the water level sensor in a Kuppersberg dishwasher, you will need to partially disassemble the appliance if a clogged filter or a broken hose plug is not the problem. It is preferable to trust this to a service center that will perform repairs for free if the machine is still covered by warranty. Go ahead and partially disassemble the item if the warranty has expired.
- Disconnect the machine from the power supply and water supply.
- Open the door of the washing chamber.
- Remove all baskets from the hopper.
- Remove the trash filter, and then use a sponge or rag to remove the liquid from its seat.
- Put the machine on its back side.
- Remove the clamps from the tray, and then remove the bottom of the dishwasher itself.
- Disconnect all wires from the float sensor, and then unscrew the bolt that holds the part.
- Find the water level sensor, which looks like a plastic box with a tube connected to it.
- Disconnect the pipe from the sensor using pliers.
The Kuppersberg dishwasher has been partially disassembled; the pressure switch diagnostics are the only thing left to do. Starting with the mechanics, you will need to listen to the sounds and blow into the part fitting. The sensor switch and the device itself are in good condition if you hear audible clicks.
Checking the electronics is even simpler and should be done with a standard multimeter. Put the tester in ohmmeter mode, attach its probes to the water level sensor’s contacts, and examine the information that appears. It is not necessary to replace the pressure switch if the indicators tend to zero out.
You should also check the pressure take-off tube, as it might be clogged. If this is the case, cleaning the tube will suffice. Repairing the unit is useless if a malfunction is discovered during any of the element’s inspection stages. Instead, a new part needs to be installed.
Once you purchase a new pressure switch from Kuppersberg that is appropriate for your "home assistant," the component needs to be installed in the opposite order specified by our instructions. After the part is replaced, make sure to check the machine’s functionality to see if the E2 error has disappeared.

When a Kuppersberg dishwasher displays error E2, it typically indicates a problem with the drainage or water supply. A kinked hose, a clogged filter, or a problem with the water inlet valve could be the cause of this issue.
Make sure the water filter is clean before attempting to fix the error. The water flow can be interrupted by a blocked filter, which sets off the E2 code. Next, look for any bends or kinks in the hose that could be preventing the water from flowing. Often, the problem can be fixed by straightening out the hose.
Should these measures prove ineffective, there’s a chance that the water inlet valve is malfunctioning and has to be replaced. Frequent upkeep and timely correction of such issues can help your dishwasher last longer and function more efficiently.
