How are Neff fault codes deciphered?
The NEFF dishwasher malfunction warning system does not have a standard set of codes. Each model may have its own. Therefore, we included in the list all possible combinations of letters and numbers that may appear on the display of any PMM model of the Neff brand.
Let's consider the meaning of the codes available to the user without test (service) mode:
The error may appear after the control module has been replaced. Try rebooting your device. (How to restart the PMM, read after the list of errors.)
If any other alphanumeric combination appears on the screen (which is not in the list), then a technical malfunction has occurred. You can try to correct the situation by rebooting the device.
To restart the PMM, you should:
If reinstalling the PMM was unsuccessful, you need to contact a service center for repairing household appliances.
We figured out what this or that code means. But sometimes a signal that the dishwasher is not operating properly is accompanied by lights on or flashing on the control panel. Let's look at their meaning below.
Read below to see what other problems arise when the dishwasher is running.
Causes of malfunctions of the Neff dishwasher
Other malfunctions may also indicate a malfunction of the NEFF dishwasher. In most cases, they arise due to improper use:
We will tell you below how to eliminate other malfunctions in the operation of the Neff PMM with your own hands.

Bosch in some cases can be done independently.
If one of the burners or the entire device does not work when the power is connected, we carry out the following work:
Removing the hob
If you are repairing a glass-ceramic hob with your own hands, you should know that the incorrect operation of some structural elements can only be detected using a multimeter, by taking measurements on individual sections of the circuit. When considering a Bosh cooktop, you should pay attention to the following elements:
If there is no resistance or low readings, these elements should be replaced.
The operation of some structural elements can only be determined using a multimeter
Repair of NEFF dishwasher breakdowns
The decision to independently repair a dishwasher that is under warranty must be balanced. Since further repairs under warranty by service center specialists will be impossible.
Let's look at how to fix the most typical breakdowns of Neff brand PMMs.
Before starting repairs, make sure that the device is disconnected from the power supply and water supply.
Water leak
The most unpleasant situation that requires quick action. First of all, it is necessary to identify the location of the leak.

Problems in the drainage system
The drainage tract suffers most often, since many owners ignore the basic rules for operating equipment, namely:
Understanding why this is necessary comes only after the car “reacts” with a breakdown.
How to fix the drain system:
If the drain pump itself is faulty, it must be replaced.
Poor washing quality
Dirty dishes after washing indicate that the equipment has ceased to cope with its direct responsibilities. The reason should be sought in the following:

If the quality of washing remains the same, the problem should be sought in the malfunction of the circulation pump or heating element.
It is better to entrust the elimination of serious faults, such as failure of important components of the device or control board, to a specialist. After all, sometimes independent repairs can further aggravate the problem.
Connecting the hob to the mains
CONNECTING THE HOB TO THE ELECTRICAL NETWORK
— The protection of the electrical connection must comply with current requirements and
— Before connecting, you must check whether the voltage specified in the factory
plate with the actual network voltage.
— In case of a permanent connection to the electrical network, install a multi-pole disconnector
a device with a distance between open contacts of at least 3 millimeters. Will fit
fuses, protective current switches, etc.
— The connection must take into account the capabilities of the fuses and the current load of the electrical network.
— After installation, it is necessary to ensure complete protection from contact with conductive and
The device can only be connected to the electrical network by a specialist from an authorized service center. The warranty does not cover malfunctions associated with improper installation and connection of the device. Before any intervention, disconnect the device from the power supply.
Operating and Installation Instructions
To repair a dishwasher, you need to understand the processes that occur in it. This is the only way to determine the possible causes of the breakdown and eliminate them as soon as possible.
Let us describe the general principle of operation of a dishwasher. The operating algorithm is usually the same for all manufacturers, although some changes may occur. Next, we will describe the most time-consuming process - washing dirty dishes with time to “acidify” the remaining food.
Rinse water is supplied from all sides
Water is supplied from the nozzles under pressure
As you can see, a large number of sensors are involved in the process. All of them can fail and cause a breakdown. Filters, nozzles, and sprinklers may also become clogged. All these are causes of failure.
What do the error codes that appear indicate?
To understand the essence of the problem, you need to figure out what caused the error in the dishwasher. Each manufacturer of a device such as a dishwasher may have completely different faults. Therefore, it is important to understand what exactly it means if your dishwasher shows error e15. Information about this must be indicated by the manufacturer in the user instructions that come with any product. Unfortunately, in most cases we turn to it only when something breaks, but there you can see how error e15 is deciphered, and you can understand what is burning, what is leaking, or what has become disconnected and led to the breakdown. Having determined the cause of the breakdown using the instructions in the instructions, it is possible to correct the situation.
Why is the i20 indicator blinking on the dishwasher screen? We recommend reading this article.
Deviations in the operation of the dishwasher can occur either due to software failures or due to serious breakdowns of components or spare parts. Here you can determine the malfunction thanks to the dishwasher diagnostic system:
Household appliances are replenished with new products literally every day. Such well-known companies as Bosch, Beko, Electrolux, Indesit, Samsung and many others indicate errors using digital and alphabetic values.
There are two options to reset the dishwasher errors that appear.
When you understand the reason for the unit error and have thought through a further plan of action, you can reset the error code that appears.
There are two simple options for this:
These are universal “recipes”, so you can safely use them, regardless of the brand of your washing machine.
In what form is error e15 presented?
If the dishwasher shows error e15, this means that the water stop system (Aquastop) has worked. This error is absolutely easy to fix, but here you need to pay attention to the tasks that are imposed on this function.
AquaStop is an improved system used in new models of dishwashers to protect against unauthorized spills and leaks. If a similar error appears in Bosch dishwashers, you should not ignore it, but immediately begin eliminating E15.
If the machine has an AquaStop system, then in the event of depressurization, leaks, overflows and other incorrect actions of water flows, excess water is automatically redirected to a special container. It is designed for a volume of 0.2 liters, therefore, when the container (tray) is filled with excess water, the float rises sharply. All these actions cause the contacts of the small switch to close. This blocks the flow of electricity to the safety valve and stops the water flow until the faults are fully adjusted. At the same moment, water begins to be pumped out of the base.
Typically, error E15 practically never occurs in Bosch dishwashers, since this manufacturer takes the leakage safety system very seriously. But in rare cases, you can cope with it yourself and without extra costs.
Frequent causes of breakdowns
For equipment with an electronic display, the causes of malfunctions in the form of codes are displayed on the screen. The instructions for the equipment tell you what to do if a particular error occurs. But in some cases, independent repair is impossible. The difficulty is that most of the Neff dishwashers are built-in; they must be disassembled to find the breakdown. In addition, special diagnostic devices are needed.
It is better to entrust Neff dishwasher repair at home to a professional who will promptly detect the breakdown and offer a solution.
The most common malfunctions:
Solving problems often requires installing new pumps, valves, and sensors. You can also replace the heating element and control unit.
Dishwashers of considerable age have natural problems associated with wear and tear. For example, it is necessary to replace cuffs and loops. Install new knobs, buttons, indicators. All this work is done quickly and is inexpensive, much cheaper than the cost of a new dishwasher.
Sometimes what is needed is not repairs with the replacement of components, but cleaning, adjustment, and tuning of equipment.
How to properly fix the breakdown?
What to do if your dishwasher displays error e15? The best solution is to read the user manual. If you bought a unit from Siemens, Veko, Electrolux, Neff, Indesit, then it occurs due to blocking of the AquaStop system. This means that more than 0.2 liters of liquid has accumulated in the pan, which slowed down the functionality of the machine.
You can restore the dishwasher to working order and remove error E15 as follows:
- First of all, empty the tray of excess liquid. Simply tilt the dishwasher and drain the water. Don't forget to prepare a container for excess in advance!
- Dry the unit thoroughly. Under good heating conditions in the room, a day will be enough for it to dry completely.
- The drainage system is being cleared of blockages. To do this, simply open the filters almost at the bottom of the machine and carefully check the drain into the sewer.
- These actions do not interfere with the further operation of the dishwasher in normal mode.
To prevent your dishwasher from displaying error E15, you must be careful when using it, do not overload it, and pamper it with cleaning products and care accessories.

3 common breakdowns of the NEFF dishwasher: causes and repairs, deciphering error codes, Error E15 in the neff dishwasher, how to fix it.
Error codes for PMM Neff with display
Error codes on Neff dishwashers with display are displayed in alphanumeric format E<code>. But some malfunctions are reported not by an error code, but by the lighting or blinking of one of the indicators on the control panel.
Even in modern Neff PMM models, not all error codes are displayed in the normal operating mode of the machine: their full set is available only in the service (test or diagnostic) mode, which is launched by a special combination of buttons on the control panel. This section will provide a complete set of error codes, and in subsequent sections we will clarify which codes are available in the operating mode of the dishwasher, depending on the model.
Unfortunately, there is no single standard in the Neff dishwasher error code system: several sets of codes are known. In order not to clutter the page with repeated descriptions of the same errors, we have collected all known error codes in one table. Where the same code will mean different errors, we will definitely report this. Please note that the codes "E01" and "E1" (without zero) are different errors.
There is a failure in the dishwasher system software or the control module is faulty. If rebooting the PPM does not help, you need to call a specialist for diagnostics.

There is little you can do in this situation yourself, but you can still try:
Water heating does not start because problems have been detected with signals from one of the sensors or the heater:
See also: “The dishwasher does not heat the water: reasons”
Most likely, something happened to the heating element relay that controls the operation of the heater
As a result, the temperature of the water in the tank will differ from the set one, which will affect the quality of the wash:
Problem with the additional heating element relay that controls the operation of the heater
See also: “Dishwasher does not dry dishes: reasons”
Depending on the model, the dishwasher will either wait until the tank is completely filled with water (this was the case in early models), or the washing will stop after a minute (a more reasonable solution in modern models)
See also: “The dishwasher is humming and does not fill with water”
See description of error "E02"
A problem has been detected with the flow sensor (switch): it is in the wrong position, but the error can be caused by other reasons:
See also: “Dishwasher does not wash dishes well: reasons”
See description of error "E01"
A pressure sensor or float indicates that the machine is overfilled: usually the cause is a blockage or malfunction of the water supply path:
As a result, the electronics block the start of the wash. Possible reasons:
See also “Dishwasher door won’t close”
Cleaning continues assuming heavy soiling
See also: “The dishwasher leaves a residue on the dishes”
The suction hole (on the right side inside the appliance) can be blocked by dishes
The electronics do not allow heating because the circulation pump has detected that there is too little water in its cochlea
The heating element circuit is open, no signal is received from the heater
Either there is no signal from the sensor at all, or it shows incorrect data:
A too thick layer of limescale (scale) has accumulated on the heater, causing it to cope poorly with heating water and drying dishes.
See the article “How to descale your dishwasher”
The error occurs when the PMM is connected to hot water and water with a temperature above 75 degrees is poured in.
If there is no signal from the water fill sensor, while the circulation pump is working normally, the electronics blocks the wash, since there is no way to control the process of filling the tank with water. Standard actions for problems with the sensor: check the wiring and contacts, the sensor itself and the control controller.
A signal was received from the float of the Aqua-Stop leak control system, which indicates the appearance of water in the pan
See also: “The dishwasher is leaking”
A leak has been detected either through the fill valve or through the flow sensor (water meter): this may lead to spontaneous water intake
The fill valve is difficult to close due to too high incoming water pressure. As a result, too much water may fill into the tank.
The washing does not stop, although its quality is unlikely to be good. Most likely there is a problem with the fill valve, but there may be other reasons: see the description of errors “E3” and “E14”
See also: “Detergent remains in the dishwasher”
The control module has detected abnormal parameters of the electrical or electronic circuit of the pump motor
There can be many reasons for drainage problems:

The control module has detected abnormal parameters of the electrical or electronic circuit of the pump motor
What to do when the Neff washing machine gives an error?
The electronic sunroof lock is broken.
There may be the following reasons:
- The door is not locked tightly, or a foreign object has gotten into the hole where the latch goes. Inspect the cell for foreign objects.
- Check the electronic sunroof lock for damage to the wiring and the quality of the terminal connections. If a defect is found, correct it.
- Error in the control unit. To test it, special devices are required, so you will have to entrust this to a qualified technician.
e01
The Aquastop sensor has tripped. This happens when water leaves the drum, that is, a leak has occurred. Carry out a visual inspection of the units where there is water. Pay special attention to the rubber seal on the door.
If you find a small hole, you can patch it yourself. Also, often where a leak occurs, this is the tray where the powder is poured, or rather, in the hose that is connected to it. Tighten the couplings.
e05
There is no water in the tank. A similar error often occurs when an emergency drain is triggered or the drain pump breaks down.
- Check the system for leaks, if found, fix them.
- Next, you need to make sure that the pump is working properly; very often it is enough to clean or replace the brushes. And if you find a break in the winding, you will have to buy a new one.
- Also, the problem may lie in the pump, in which case it is necessary to install a working one.
e06
Water does not drain. This could be caused by:
- Broken wiring between the pump and the module. Inspect it and call, if you find a damaged area, isolate it or install a new cable.
- The drain pump is broken. Clean, ring the winding, if necessary, purchase a serviceable one.
- Problems with the control board, this will require consultation with a specialist.
e07
A leak has been detected for devices where drying is provided. The reason lies in the violation of the tightness of the connections and pipes, or the rubber seals have lost their elasticity. Check the valve located near the inlet hose.
e16
The control unit did not receive a signal to close the door.
This could happen due to the following:
- The door was not closed properly.
- The door locking mechanism is broken and needs to be replaced.
- The handle or hinges are broken.
- The electronic circuit of the UBL and the control unit is broken, or the contacts are oxidized, this often happens because it is installed in a room with high humidity.
e17
Water does not enter the tank, reasons:
- Low pressure in the water supply network, or you completely forgot to open the tap.
- The fluid intake system is clogged; to remove it, wash the inlet hose and filters.
- The pressure switch on the Neff machine has failed. You need to take it out, clean it and test it; if it is faulty, replace it.
e18
During the time allotted by the program, the liquid did not drain from the tank:
- This may be a consequence of a blockage that has formed in the drain filter; remove the filter and wash it.
- The pump is broken, it may be depressurized, look at the condition of the pump, if necessary, clean it, if necessary, replace it with a working one.
- The controller on the control unit responsible for the draining process has failed.
e19
The liquid heating temperature does not meet the parameters specified by the user/program:
- Broken heating element, replace or clean. Often, the scale problem occurs as a result of poor water quality, or constant operation at high temperatures. To avoid such troubles, it is necessary to use special products that soften the liquid and prevent scale accumulation. And do not set high temperature programs unless necessary.
- Problem with the temperature sensor, replace with a new one.
- The wiring contacts are broken, call, identify the area of the break, and restore it.
e20
Fluid temperature rise:
- The heating element relay is faulty; diagnostics and subsequent replacement are necessary.
Washing machine relay
- The sensor is reading incorrectly. Buy a new one.
- The motor brushes are worn out, replace them. When installing new ones, there may be some extraneous noise during operation for a short time, this is considered normal, the grinding process is in progress.
- The motor is broken and cannot be repaired; a new one will have to be installed.
- Problems with the control unit. It is necessary to carry out a thorough diagnosis, after which it will become known which element has failed. Perhaps it will all cost by reflashing it.
e21
The motor is faulty, reasons:
e22, e29
Fluid intake occurs uncontrolled:
- The problem is in the pressure switch or one of its elements. Replace the handset or the device itself.
- The control board is faulty. It requires re-flashing, replacement of complete or individual elements. It can be determined exactly after its complete diagnosis.
- The fluid intake hose is not in the correct position or is damaged, correct it.
- The pressure switch sensor is stuck. Clean it.
e23-e28
Problem with the sensor controlling the water level:
- The sensor tube is clogged, clean or replace.
- The tube is kinked or torn off, if possible, return to its original position, or buy a new one.
- If the contacts of the pressure switch are stuck (clean), or there is a break in its electrical wiring, in this situation it is possible to either replace the damaged section or restore it.

It is better to entrust the elimination of serious faults, such as failure of important components of the device or control board, to a specialist. After all, sometimes independent repairs can further aggravate the problem.
No water coming in or not enough water being collected
Dishwasher malfunctions are often water related. And one of them is that you don’t get enough water. It could also be that the detergent is not washed off and does not rinse well. All these dishwasher malfunctions can be caused by one reason - insufficient pressure. It is checked first. The pressure in the system must be above the minimum threshold at which the PM can be operated (found in the passport). If the pressure is normal, there may be the following reasons for this failure:
To check whether the lack of water is really the reason for the shutdown, pour water inside and start the unit
To make sure that the problem is in the water supply system and not in others, pour 4 liters of water into the machine, load some dishes and start it up. If the machine does not clean, there is likely a problem with the dishwasher control.
Knocks out the circuit breaker
Dishwasher malfunctions associated with electrical problems usually appear after power surges. Then the control also crashes. Therefore, during installation, it is advisable to take care of installing a stabilizer. If not general - for the whole apartment or house, then at least local. This could be a low-power unit for connecting a dishwasher, or maybe a more powerful one, to which you can connect several electronically controlled appliances.
Electrical diagram of a dishwasher
If, when you turn on/start the dishwasher, the circuit breaker in the panel is knocked out, the reasons may be the following:
Identifying the exact cause of most of these faults (other than seal failure) assumes that you know how to use a multimeter. Take the electrical diagram of the dishwasher, first check the condition of the fuses, then follow the diagram.
These are, perhaps, all the main malfunctions of dishwashers that you can fix yourself. If these measures do not help, you will have to resort to the services of specialists.
How to fix the problem?
Let's figure out what needs to be done to correct the situation and normalize the flow of water, preventing it from getting into the pan. First of all, we check and clean the filter, because this is where the most powerful and unpleasant blockage can occur, stopping the normal operation of the Neff dishwasher. The algorithm of actions is as follows:
- dishwashing equipment is disconnected from all systems and moved to the center of the room to make it more convenient to work;
- We recommend laying out a lot of rags at its right panel and preparing a bucket to wipe the floor;
- tilt the dishwasher to the right so that the liquid completely flows out of the washing compartment;
- if there is too much liquid, you can substitute a basin or other container that is more convenient;
- Having removed the water, you must take all measures to ensure that the body inside the dishwasher is completely dry (install the equipment near the heating radiator, use another method);
- Having opened the loading hatch of the Neff machine, remove the lower tray for dirty dishes and put it aside;
- There is a garbage filter in the washing chamber, which should be unscrewed and cleaned thoroughly. We do the same with the mesh located near the filter;
- We install all the elements in their places, connect the dishwasher and perform a test run. In most cases, error code E15 does not recur.
There are cases where blockages in the filter have a negative impact on the sealing elements. As a rule, due to excess pressure generated by a clogged dishwashing system, the modular ring in which the filter element itself is installed fails.
The worn seal is clearly visible; it should simply be removed and replaced with a new analogue. To keep your conscience clear, we recommend checking the pipes. It is likely that a crack has formed in one of them, through which water is leaking. The problem is probably related to loose mounting clamps. If you have already removed the side wall, check all the elements of the Neff dishwasher that appear before your eyes.
Dishwasher error codes
Alarm about malfunctions, self-diagnosis of electrical and hardware circuits - error codes for dishwashers. Over the past 6-7 years, manufacturers have been introducing dishwashers into the mass segment. A partial list can be found in the instruction manual. The table from the manual describes the encoding associated with minor and easily fixable problems - you can fix it yourself. The functionality of fixing a dishwasher with your own hands, according to the manufacturer, comes down to three areas:
Point 3 can be easily accomplished only with PMMs from the BOSCH group; the rest do not provide easy access to the pump.
For other dishwasher signals, contact a Good Master. Information on videos and forums is always silent about the subtleties, and that’s the whole point. Error E15 Bosch dishwasher is a classic example.
Common problems and coding are described below.
