Error E25 in a Bosch dishwasher (Bosch) - causes, repair

Does your Bosch dishwasher show error E25 on the display? This indicates that the system is clogged. Find out how to find and fix the problem yourself below.

Most often, when a dishwasher malfunctions, it displays an error code. The control board controls the operation of the nodes, so as soon as one of them fails, fault icons are displayed on the display.

Fixing error e25 in the dishwasher

Household appliances have been faithfully serving people for many years, making their lives easier and taking on all the dirty work. Such items include a dishwasher. It is this that saves users from the need to wash a whole mountain of dirty dishes with their hands, because they also have time to go to work, and there is no time in the evening.

The code means the drain pipe is clogged

Currently, there are models on the market from the world's leading manufacturers. One of the most popular brands of dishwashers is the model from the German manufacturer Bosch. Household appliances from this manufacturer are popular due to their low prices.

Decoding

The factory interpretation of error E25—reduced coolant circulation—does not provide a complete understanding of the essence of the problem. In the instructions for various models of the Baxi boiler, the emphasis is on blocking the pump. But this is not the only reason such a fault code appears on the display.

Error e25 indicates an intense increase in temperature in the heating circuit. This parameter in Baksi units is determined by the difference in readings from sensors installed at the inlet and outlet of the boiler heat exchanger. When it grows at a speed above 1 0 C/sec, the operation of the unit is blocked by the protection circuit. A decrease in fluid circulation is caused by several factors, therefore there is no clear recommendation for eliminating error E25. The algorithm of actions given in the article will allow you to figure out the reason for the appearance of this fault code in a short period of time.

Meaning and reasons for the error

Code E 25 informs the user that there is a blockage in the dishwasher system. The literal interpretation is: problems with the drain pump or a clogged drain pipe.

Each dishwasher comes with instructions that indicate the exact meaning of all faults of this model.

The problem with the pump may be due to blockage of the impeller, which is caused by foreign objects falling into the drain during washing:

• bones;
• peels from fruits and vegetables;
• pieces of napkins;
• toothpicks;
• broken dishes.

Even if you carefully clean the plates of food debris, the filter could become clogged with grease. When your dishwasher is not cleaned properly, grease from the appliances accumulates in the drain system. As a result, it clogs the drainage filter, hoses, and pipes.

How to fix the problem yourself? You need to start cleaning the car.

Causes of problems

Error code E25 can appear on the display most often due to the drainage system being clogged with food debris or debris, when the owners themselves neglect the basic rules of operating the equipment when working with it. So, in the drain of the PMM system itself, a blockage can form from:

1. bones (even the smallest and softest meat/fish);
2. fruit seeds;
3. peels and napkins, as well as toothpicks;
4. fragments of broken dishes and so on.

And even if, before putting it into the system itself and starting the dishwasher’s wash cycle, you clean the dishes from food residues, this, as practice shows, may not be enough. The blockage of the pipes itself can occur due to the fact that they have not been cleared of accumulated fat for a long time. And, as a result, it can accumulate in the steam chamber and thereby create a traffic jam.

Accordingly, the pump cannot pump out water in this case. And in this case, the only question arises - what to do? The only way out is to clean the pipes and remove the blockage.

Restoring the operation of the Bosch PMM

Before you begin directly to work, rule out a failure in the electronic system at the very beginning. In this case, the equipment may mistakenly display this code on the display screen. And to reset such an erroneous “action” of the machine, follow these steps:

1. Disconnect the equipment itself from the power supply system to ensure the safety of all work - compliance with safety rules has not been canceled.
2. Let the equipment stand for 15 minutes - this will allow you to reconfigure the system during the next startup and return the settings to the previous operating parameters.
3. Connect the system to the power supply - if this code appears on the display again, you will have to have the equipment professionally disassembled and clean the blockage.

If the reason is a blockage and not a failure of the electronic settings, at the very beginning you remove the water that accumulates at the bottom of the dishwasher. But at the very beginning, so as not to electrocute you, be sure to de-energize it by disconnecting it from the power supply. And then proceed to these steps:

• Take out the basket with dirty and unwashed dishes and also remove the lowest trough so that it does not interfere with the cleaning process.
• Scoop out the remaining dirty water from the machine and carefully unscrew the filter cover without jerking.
• Next, remove the filter glass itself from the system.
• Inspect it and blot up excess moisture with a rag.
• Take long and preferably thin tweezers and carefully remove the flap covering the impeller of the nose.
• Inspect and remove the blockage itself and then check the operation of the impeller itself.

Upon completion of cleaning, all parts are placed in their working places in the system in the PMM. And if this does not help, then you will have to clean either the drain system hose itself or the pipe, reaching through the bottom of the machine.

After that, place it on the back wall, open the bottom, remove the panel and disconnect the wires. When the bottom is removed, the filling of the unit is revealed. After detaching the formwork, clean it. There is a hose connected to the pump - disconnect that too and rinse it completely. To do this, you should use a special cable with a brush. And after cleaning, return all the parts to their place, connect the unit to the electrical power supply.

If the drain pump fails, much will depend on the nature and type of failure. If the impeller breaks, it is replaced with a new one. But if the winding itself burns out in the system, the pump should be completely changed. Although, as many PMM owners and craftsmen note, if you do not have sufficient experience and knowledge in repairing equipment, it is better to call an experienced specialist.

Main causes of typical malfunctions

Even such reliable equipment as Bosch can fail for completely banal, everyday reasons, for example, due to loading excessively dirty dishes into the washing chamber. Residues of food washed away by the flow of water will clog the filter and cause clogging.

If the loaded dishes are too dirty and greasy, the unit will not be able to rinse them efficiently, and the housewife will have to additionally rinse the plates and cups by hand

To avoid this situation, it is better to first clean the food left on the plates before placing them in the machine.

An incorrect connection to the electrical network and a faulty socket have a bad effect on the dishwasher. A drain hose that is too long or poorly secured in the water supply area can also create problems, so installation and installation should be entrusted to professionals.

If the home master wants to do this himself, it is necessary to strictly follow the installation instructions and strictly comply with the requirements prescribed by the manufacturer in the passport supplied with the unit.

Dishwasher detergent must have a normal shelf life. It is recommended to buy it in a specialized store where the rules for storing household chemicals are observed.

A lot of inconveniences, and subsequently problems, are caused by improper loading of dishes into the washing chamber. Many users do not pay attention to this point and then encounter various problems.

In order for the washing process to proceed normally, the dishes in the sections must be placed compactly. Then it will not interfere with the rotation of the irrigation rockers, the timely opening of the dispenser, the free passage and uniform flow of water

Before loading plates, cups and cutlery, you must carefully study the instructions for loading dishes and take into account all the wishes put forward by the manufacturer of the equipment.

Dishes placed correctly will be perfectly washed and will not require any additional action from the housewife. In this case, the machine will not feel overload and will serve well throughout the entire operational period.

We recommend that you familiarize yourself with the operating instructions for your Bosch dishwasher in order to avoid problems in the future due to their violation.

What does this code mean

Error E25 in this German brand machine informs the user that the pipe that connects to the drain pump is clogged. On some models, this may not be a pipe, but the base of the drain hose connected to the pump.

Another interpretation of error E25 sounds like this: the drain pump is blocked or its cover is missing.

It is clear that the impeller in the pump is blocked by some foreign object or debris. This error can appear not only when there is a blockage, but also when there is no cover on the pump.

Causes

The cause of this error is most often clogged with debris and food debris when the user neglects the simple rules for operating this equipment. The following may get stuck in the dishwasher drain system:

• bones from meat (fish) or seeds from fruits;
• fruit peel;
• napkins;
• toothpicks;
• fragments that broke while washing dishes.

Even if you clear the plates of leftover food before placing them in the dishwasher basket, this is not enough. A blockage can occur if the user does not rinse the machine of grease for a long time. As a result, fat accumulates in the pipe, creating a plug through which the pump cannot pump out water. There is only one way out - cleaning.

Troubleshooting

So, if the dishwasher has stopped and a clogged error appears, then first of all you need to remove the water that is at the bottom of the machine. But first, disconnect the equipment from the electrical network, and then follow these steps:

1. Pull out the baskets with dishes.
2. Remove the lower rocker arm so it is out of the way.
3. Scoop out the dirty water into a separate container.
4. Unscrew the filter cover.

   

5. Pull out the filter cup.
6. Inspect what's inside and, if necessary, blot up all the water with a thick rag.
7. Take long tweezers and remove the flapper that covers the pump impeller.

   

8. Inspect the impeller, remove any stuck debris with tweezers, and check the operation of the impeller.
9. Put all the parts in their places, check the operation of the dishwasher.

If the work done did not help, then you will have to clean the drain pipe or hose. You can get to these parts through the bottom of the dishwasher. Let's free the car from dirty water, take it out to a free place, disconnecting it from the water supply and sewerage. Then place the car on the back wall and unscrew the bottom, be careful not to pull the tray, there may be wires going to it, they need to be carefully disconnected.

When you remove the bottom, all the details will immediately open. Disconnect the pipe from the drain pump and clean it. If a hose is immediately connected to the pump, then disconnect the hose and rinse it completely using a special cable with a brush. Then return all the parts to their places and check the operation of the equipment.

If cleaning the machine does not help, which is unlikely, then error E25 appeared in the Bosch dishwasher due to a broken drain pump.

If the drain pump breaks down, everything will depend on the nature of the breakdown. If the impeller breaks, replace this part in the pump, but if the winding burns out, then replace the entire pump. Don't rely on your abilities and capabilities? Call qualified specialists.

We will stop our story here. We hope now you know why error E25 may occur in your dishwasher. By the way, if it is interspersed with other errors, then their decoding can be found in the article Errors in Bosch dishwashers.

How to disassemble the machine and clean the filters

As soon as the display shows error information, you should not do it the old fashioned way - turn it off and on again. This method won't work. To clean the drain channel, you must perform the following steps:

• Disconnect the dishwasher from the electrical network;
• Turn off the water supply and disconnect the inlet hose;
• Collect all stagnant water in the bunker using rags in a bucket or any other container;
• Unscrew the cap from the filter;
• Remove the screw located at the very bottom of the hopper;

Before you begin disassembling the machine, collect any stagnant water.

In this case, it is not necessary to remove the pump - it is enough to use long tweezers or sharp tools to remove all the debris.

Now try running the dishwasher again. If that doesn't help, try disassembling the dishwasher by removing the tray to get to the drain pump. Here everything depends on the type of malfunction of the drain pump. These issues require consideration in a separate topic.

Spare parts for drain pump

Two ways to reset dishwasher errors

If the cause of the failure has been established, you can reset the program. You can withdraw using one of the following methods, which you can choose depending on the situation:

1. You need to press and hold the Power button for 15 seconds.
2. The PMM should be disconnected from the power supply for 20 minutes. During this time, the control module will reset the settings and restart.

Such simple recommendations will help you deal with the problem of any brands and models of dishwashers. You can watch the video as a sample of the work.

Baxi boiler error e25 how to fix

To eliminate error E25, you must first of all understand the reasons for its occurrence. The main, most common ones were described above. There is no need to thoughtlessly reset it and see what happens. If there is actual overheating on the heat exchanger, “boiling” during experiments can lead to its failure. Study the reasons for the error, perform the necessary checks, starting with the simplest ones. If nothing works, it is better to call a service specialist from a service organization. We hope that the material in this article was useful and if you have additional questions or suggestions, you can ask us via chat or feedback form. Finally, you can see what a boiler circulation pump looks like in disassembly and the main reasons for its malfunctions.

Bosch dishwasher heating error codes

Possible errors in Bosch dishwashers related to heating are reflected in the following block of codes:

1. Code E01 (F01) - lights up on the screen if the heating element (heating element) malfunctions, or if its circuit is broken. It is possible that the electronic module of the element that controls the heating element may fail.

How to fix the error:

• The heating element is checked. Zero resistance or a breakdown to the housing may be detected. The heating element cannot be repaired, but is completely replaced;
• the safety thermostat is checked;
• The temperature sensor is checked.

2. Code E2 (F2) - appears on the display in case of malfunction of the sensor that controls the water temperature. This error usually alternates with code E01 (F01). The temperature sensor should turn off the heating element after heating the water. In the event that it fails, the heating element overheats the water.

How to fix the error:

• the resistance of the sensor is measured at the contacts;
• if the resistance value is low, the sensor must be replaced.

3. Code E09 (F09) - lights up on the screen in case of malfunction of the flow heater built into the circulation pump.

How to fix the error:

• The device checks for breakage of the heating element;
• at zero resistance the heating element changes.

4. Code E11 (F11) - appears on the display if the heater is turned off. As a rule, in this case, the control signal does not arrive at the temperature sensor, or there is no supply voltage to the sensor.

To identify and eliminate errors, check:

• internal resistance of the temperature sensor;
• internal resistance of the control module;
• condition of the temperature sensor wiring.

5. Code E12 (F12) - lights up on the screen if there is an increase in scale or dirt on the heating element.

How to fix the error:

• The condition of the heating element is checked. If after a reboot the code E09 (F09) is displayed, then there is a lot of scale;
• the heating element is removed, cleaned and reinstalled.

Advice

When installing NTC in the boiler, do not forget to change the gasket (RTI is not reused) and apply a fresh layer of thermal paste to the Baxi internal circuit tube (for the clamp-on sensor).

Electronic board

Based on the information coming from the NTC, it generates error e26: the voltage is removed from the relay, through the contacts of which power is supplied to the Baksi boiler pump. If the cause of the problem is not identified when testing the heating system and unit, it is in the control module.

Baxi boiler control board

Self-diagnosis is impractical: you need a stand, detailed diagrams, and manufacturer’s guidelines. This is the case when a service technician is called. The cost of the board, depending on the modification, reaches a third of the price of the heating installation: experimenting or buying a new unit only if you suspect it may be a waste of money.

Dishwasher Error Codes

E1.

Heating error, heating element is faulty. In most cases, this error occurs due to contamination or failure of the heating element (heating element).

To check the serviceability of the heating element, you will need to disassemble the equipment and ring the element with a tester. It is better to entrust the solution to this problem to a specialist. If the heating element fails for any reason, the part will have to be replaced.

A new heating element costs at least 3000 rubles. Also, the problem of heating water and the appearance of error E1 can be caused by a malfunction of the safety thermostat, flow sensor and water level sensor (pressostat).

E3.

There are problems with filling the water. An error will appear if the required water level in the PM has not been reached for some time. There can be many reasons. It is worth paying attention to the following possible problems:

• The hose or Aquastop sensor is damaged (how to treat this problem, see error E15 just below)
• Drain pump faulty
• Intake filter clogged
• Water level sensor is faulty
• The inlet valve is faulty.

E4.

Faulty water flow switch. This part is responsible for distributing water in the sprinkler. If it is faulty, water will be spent irrationally (more water will flow to one part of the dishes, less to the other). The problem may be caused by a simple clogged switch. How to fix the problem - you just need to clean the switch.

Sometimes the problem may be due to a motor malfunction that moves the flow switch to one position or another.

E5

indicates that the water level in the machine is exceeded or the PM is overfilled. This will not always mean that the car is actually flooded with water. The real problem may be caused by a faulty water level sensor (pressostat), a clogged pressure switch tube and a faulty inlet valve.

To solve the problem, you will need to turn off the PM and get to the level sensor, carefully inspect the sensor tube for clogging. At the same time, you should use a tester to check the serviceability of the water level switch and, if necessary, replace the part.

E6

Aquasensor malfunction. The main function of the aquasensor is to determine whether dishes are dirty. If the dishes are not very dirty, the aquasensor can eliminate some washing steps, such as rinsing.

This allows you to further save water and energy. A faulty aqua sensor can also be replaced. It is located next to the PM heating element (heating element).

E8.

Occurs when the water level in the pan is low. The reason may be low water pressure (check, maybe there is temporarily no water in the house) or problems with water drainage (for example, due to improper connection of the dishwasher to the water supply and sewerage system).

E9.

Indicates a malfunction of the heating element. There may be a break in the heating element circuit.

E11.

The machine works without a heating element. Similar to the previous error, however, the problem here may be caused by a malfunction of the NTC sensor (see error E2), broken power wires, or a malfunction of the electronic module.

E14.

Error in the flow sensor, which does not detect pulses going to the control module.

E15.

Literally means that Aquastop has worked. That is, water no longer flows into the dishwasher. Possible reasons: There is a water leak. This is a rather unpleasant error, since it is not immediately possible to understand the nature of its occurrence.

After all, there can be many reasons why water leaks occur. The aquastop sensor may be malfunctioning, the water supply system may be installed incorrectly, or the hose may be damaged.

Often, the cause of error E15 is the installation of the siphon above the level of the Aquastop sensor. To fix this problem, you need to install a drain at floor level, directly into the sewer. How to fix this error is described in the following video:

E16.

Uncontrolled water intake. The system detects that excess water is entering the PM. Possible causes of the problem are failure of the intake valve or pressure switch. The problem may also be caused by excessive foaming.

E17.

Problem with water filling. Similar error to the previous one, but the problem here may be related to high inlet pressure. It's also worth checking the flow sensor.

E21.

The drain pump is blocked. Most often, this problem occurs due to improper operation of the machine. If you do not clear large items of food from the dishes before loading them, they will contaminate the drain pump and sooner or later the equipment will show you error E21.

Fixing the problem is not difficult. To do this, you need to remove the drain filter and rinse it under running water.

The problem may also be due to contamination of the water supply blades. The lower and upper blades can be removed very simply and can also be cleaned with a stream of water.

E24.

Problems with draining water. The probable cause is a clogged, broken or jammed drain hose. It is not difficult to check and fix the problem.

Article on the topic: When a plotter cannot be repaired

E27.

Low voltage in the network. The error occurs when the network voltage is low, for example during peak hours on the local power grid. This problem may occur in the evening. To make sure of this, you should check the voltage in the outlet (trust a specialist). Options to fix the problem: 1. Just wait until the voltage rises. 2. Install a voltage stabilizer.

How to proceed

Check electrical parameters

Imported boilers are sensitive to U, f. Manufacturers do not take into account the nuances that we constantly encounter: voltage surges, increased/lowered values, phase imbalances and other “surprises”. With an autonomous power supply, error E98 of the Baksi boiler is caused by incorrect operation or failure of the source (diesel, gas generator). Check, make adjustments - for this, the owner of the object does not need the help of a service technician.

Advice . Connecting the Baksi boiler via a UPS eliminates the risk of error E98 due to instability of the network voltage.

Expert opinion

Uninterruptible power supply SKAT

Check grounding

This is the main reason for the appearance of error E98 in Baksi boilers installed in apartments. In houses built according to old designs, grounding is not provided. It is easy to verify by removing the cover from the socket: two wires enter the nozzle box - phase and zero.

In the private sector, circuit testing is carried out with a device - a megohmmeter. When measuring resistance, R should show no more than 4 ohms.

Grounding the baxi boiler

Check the potential on the metal part of the boiler

Error e98 may be associated with interference (stray currents). They appear for various reasons (a power line is located nearby, a powerful radiation source, the insulation of a power cable is damaged, or something else), but the result is the same: where there should not be potential, it is present.

Advice . The gas pipe is metal, laid in the ground, so the energy going into the ground is “collected” on it. To eliminate the influence of interference on the electronic board, you need to install a dielectric coupling on the main line (between the shut-off valve and the Baxi boiler). Helps get rid of error E98 and a number of others.

Connecting a dialectical coupling

one dielectric coupling

Check boiler settings

One of the reasons for error E98 after replacing the Baksi electronic board. The code appears if the parameters (F03, 12) are entered incorrectly. To correct the configuration, you do not need to call a service technician - the instructions describe in detail the setting method.

How to prevent blockages in the future?

In this case, you should follow a number of simple rules and recommendations:

1. After eating, carefully clean the dishes from food residues before placing them in the dishwasher chamber itself.
2. After each dishwashing or dishwashing cycle, make it a habit to clean the drain in your machine from food debris and grease accumulation.
3. Carry out a complete professional cleaning every six months using both physical and chemical methods. So, all parts should be cleaned manually and after installation, run the machine at idle speed.
