Error E23 Bosch dishwasher how to fix

Modern household appliances, including dishwashers (hereinafter also referred to as dishwashers, PMMs), can diagnose themselves. In the event of a malfunction, electronic systems generate error codes for Bosch, Siemens, Electrolux dishwashers and units of other brands. This makes it easier to localize the breakdown and speeds up repairs, even if it is carried out not by a specialist, but by the user.

Without an error code, locating a problem can sometimes be difficult

How to fix error E23 on a Bosch dishwasher

An unexpected activation of the self-diagnosis system of a Bosch brand dishwasher is usually accompanied by a complete stop, until the “irritant” is eliminated and the unit is restarted. The “irritant” in this case is a breakdown or system failure, to which the self-diagnosis program reacts. In this publication we will look at error E23 in a Bosch dishwasher. We will focus on the causes of this error and how to quickly eliminate them, preferably with your own hands, so as not to overpay.

Washing does not start

In such cases, the machine turns on, the indicator lights up, but the wash does not start. Or the program freezes. What is the reason and how to repair the equipment:

• System failure. If the dishwasher does not work normally after a power outage, reboot.
• The car door is not closed tightly or the lock is faulty.

Let's look at the last problem in more detail. The lock secures the door electronically. The tightly closed door should click, after which water intake and washing begin. Press it tighter. If the lock does not work, it needs to be replaced.

• Open the dishwasher door.
• Remove the screws from the inside.
• Open the outer panel slightly.
• Disconnect the lock wiring and install a new element.

Closing problems can also arise for the following reasons:

• Incorrectly installed utensils. Check the arrangement of objects in the chamber, push the trays deeper.
• The dishwasher body is not installed level. The PMM should be located on a hard, flat surface, strictly level. Tilting the cabinet may cause the door to not seal properly.

Blockages in the filling path lead to the suspension of the PMM operation. Clean the systems to ensure normal water flow into the hopper.

We have listed the problems that most often occur in Bosch dishwashers. Due to their popularity, service calls are higher than for other brands. But now you know that many problems can be fixed with your own hands.

Why does it occur

Error E23, like any other, occurs suddenly. The machine stops and this can cause real panic in some users. The only universal solution that comes to mind is to turn the dishwasher on and off. This really helps, the error disappears, but after a few minutes it appears again. Why does error E23 occur? Experienced craftsmen identify three main reasons.

1. Inability to drain waste water with a machine. This is the main reason and should be considered first.
2. Water gets into the pan and, as a result, the Aquastop system activates. This is an additional reason, which on most models is identified by the self-diagnosis system as error E14 in a Bosch dishwasher.

It happens that a Bosch machine shows errors E14, E18, E23 in turn after each reboot of the unit. This directly indicates the presence of water in its pan.

1. The dishwasher control board is faulty. This is a universal reason, because due to a faulty board, the diagnostic system also fails and can show any error contained in the database.

It is very difficult to diagnose electronic malfunctions at home. We will not describe these malfunctions, but we will advise you to immediately contact an authorized Bosch service center if they are detected.

Water in the pan

It is not difficult to determine the presence of water in the tray of a Bosch dishwasher. You need to disconnect the equipment from all communications, then pull it out to a free place, having first laid something on the floor under the body, then tilt it on its right side. A strong roll to one side will cause water to leak from the pan, if of course there is any there.

If you managed to drain a lot of water from the pan, it means that one of the hoses or pipes has lost its tightness and has begun to leak. How can I fix this problem? You will have to remove the tray, exposing the insides of the dishwasher and inspect all parts that may be damaged. First, carefully inspect the barely visible seams inside the washing chamber. Sometimes, due to a manufacturing defect, a poor-quality seam begins to let water through, which flows from the chamber straight into the pan.

Next, inspect how correctly the garbage filter is installed. Often, after cleaning it, the user puts the part in place without proper fixation. This causes water to bypass the seal and begin to flow into the pan. You also need to inspect the rubber seal around the door, especially its lower part. A worn seal can cause a small amount of water to either spill onto the floor or drain into the tray, depending on your Bosch dishwasher model. If the leak was not detected after examining the external parts, then the problem lies inside and the pan must be removed.

1. First, we remove the front door panel and the decorative panel under the door.
2. We close the door, remove the closers along with the hinge protection and open the door all the way.
3. We remove sound insulation. Underneath it, on the outer part of the pallet, you can find screws connecting the pallet itself to the main body of the machine; unscrew them.
4. We remove the garbage filter along with the mesh, simultaneously cleaning out all the dirt from there.

The lower sprinkler can also interfere with disassembly, so we remove that too.

1. In the niche of the garbage filter we find 4 screws that also need to be removed.
2. Place the machine on the back wall.
3. We remove all the parts connecting the pallet to the main body: wires, hoses, pipes, everything that may interfere with pulling out the pallet.
4. We pull the pallet gradually, separating it from the main body.

Exposed pipes, hoses, connections of pipes and hoses with other parts must be carefully inspected. A damaged pipe must be replaced. Experts do not recommend wrapping it with electrical tape or filling it with sealant.

Problems with draining water

Malfunctions caused by the inability to drain water can be caused by a burnt out pump, damaged wiring or contacts powering the drain pump, as well as a damaged control board bus. How to fix problems like this?

We disassemble the Bosch dishwasher as described above. The drain pump is located on the side of the circulation block. Turn it half a turn counterclockwise and remove it, not forgetting to disconnect the wires. We test the pump using a multimeter and, if necessary, replace it with a new one. If the problem is in the power wire, you can also find it using a multimeter.

In conclusion, error E23 creates many problems, but the problems it causes are not that difficult to fix. The main thing here is desire, determination and readiness to strictly follow the instructions kindly provided by the masters. Good luck!

Errors E20, E21, E22, E23, E24, E25 in dishwashers - causes and solutions, Error E23 bosch dishwasher how to fix.

How to fix the problem

The priority actions when a malfunction is confirmed: turn off the power to the machine, disconnect it from the water supply, empty the tank of liquid through the drain filter, and remove laundry from it.

The search for the reason for stopping the car according to E23 begins with the simplest actions, gradually moving in the direction of complex operations, and eliminates the identified malfunction.

The algorithm for checking work items is as follows:

1. SMA pan - find out whether there is water in it, as reported by the sensor. If the information is not confirmed, a false shutdown command was sent, the reason is a failure of the protection system. When they are convinced of the presence of liquid, the search continues.
2. Powder receptacle - it needs to be removed and put back in place. Leakage occurs when the dispenser is not pushed in correctly.
3. Water supply and drain hoses - inspect for cracks, tighten connections if necessary. For ease of operation, lay the machine on its side, remove the tray, and clean it of debris, which can also cause a malfunction.
4. Tank - inspect for holes and abrasions. If a gap is found, you can seal it, but it is better to replace the tank with a new one. Check the bearing assembly: if the seal is worn, traces of drips are found nearby. Pay attention to the tightness of the pressure switch tube.
5. Aquastop sensor - it is used when the error cannot be corrected by other actions. To replace the device, disconnect the wire from it and remove it from the latches, using a screwdriver. A new sensor of the same brand is placed on the freed platform.

After eliminating the malfunction, a test run of the SMA is performed. If error E23 does not appear on the screen, the repair was performed correctly.

Errors e20, e21, e22, e23, e24 and e25 in Bosch.Siemens.Neff dishwashers

If during operation your dishwasher produces one or several errors from this series. And she stopped. Don't worry ahead of time. In some cases, repairs can be done independently without the help of a specialist. But to do this, you need to figure out what the error on the display is talking about.

So. Errors of the twentieth series indicate a possible malfunction of the pumps, of which there are only two in these brands (Bosch, Siemens, Neff.):

1. This is a circulation pump - it is directly responsible for washing (injecting water into the sprinklers)
2. Drain pump - responsible for draining water from the dishwasher during operation and at the end of washing

Errors e20, e21 are displayed if there are certain problems in the operation of the circulation pump.

Errors e22, e23 and e25 indicate a problem in the operation of the drain pump.

Error E24 - according to the fault codes, indicates blockages in the drain system and problems with draining water. However, you should be aware that this error can appear even if the Bosch dishwasher drains water. The error can be caused by problems in either of the two pumps, as well as problems with the electronics.

Any of these errors can be “floating”, i.e. disappear and suddenly appear at different times when the dishwasher is running.

What can you do yourself if errors occur?

When error E20 appears, the control module has detected a winding break in the circulation pump.

• Try to turn off and turn on the machine again.
• Check the connector on the circulation pump (performed only if you have certain skills in working with equipment)
• If these procedures do not help, repair is required.

When error E21 appears, the machine has detected that the washing pump is blocked.

• A solid object gets into the pump with subsequent blocking of the impeller. — it is necessary to disassemble the PMM with subsequent removal of the pump to remove a foreign object (bone, splinter, etc.)
• Pump malfunction caused by wear. - Call a technician for a qualified replacement.

When error e22 or e23 appears, the control module has detected a broken winding in the drain pump

• Try to turn off and on again and restart the machine.
• Check the drain pump connector (performed only if you have certain skills in working with equipment)
• If these procedures do not help, repair is required.

When error e24 appears - Error in draining water.

If the water has not drained and is below or just below the filter mesh. Most likely there is a clog in the dishwasher

1. Remove the filter and rinse under the tap.
2. Check the drain hose for kinks.
3. Restart washing program

If there is no water in the machine, but an error is displayed on the screen immediately or after a few minutes, you need to call a technician for a comprehensive diagnosis.

When error e25 appears, the drain pump impeller is blocked.

When starting, you may hear clicks and strange sounds.

1.Drain the water (if any) manually using available means

2.Open the latch SM PHOTO

3.Remove the foreign object blocking the impeller

4.Build and restart the program.

If there is nothing foreign in the pump impeller. You need to call a specialist.

How to reset the program on a dishwasher, error codes and how to fix them, Error E23 bosch dishwasher how to fix.

Useful tips

Recommendations from service technicians always guide users toward preventive maintenance of household appliances, rather than repairing them. Compliance with the manufacturer's instructions for operating the washing machine guarantees its trouble-free operation for 10 years. Some tips from professionals on how to protect the SMA from leaks:

1. Do not use random washing agents for washing, use gels for automatic machines. This will protect the parts from exposure to chemicals.
2. Cleaning the dispenser (powder tray) of deposits once every 3 months is a measure against the formation of blockages and a decrease in the quality of washing.
3. A debris plug increases pressure in the hydraulic system, causing leaks in weak spots. Once every six months you need to check the cleanliness of the drain filter mesh.
4. Inspect the hoses before the next wash. If there are animals in the apartment, this manipulation is doubly necessary.
5. Abnormal voltage surges are eliminated by connecting the SMA through a stabilizer.

Experts advise starting the search for the cause of error E23 by checking the version about a foreign object under the float. If the machine body is tilted, the obstacle may roll out and the code will disappear from the display. The instructions require checking your clothing pockets before washing: small iron can pierce the pump body. The manufacturer's recommendations should not be neglected - this leads to the self-defense of the SMA.

Errors in Bosch and Siemens dishwashers

Sometimes situations arise when the question arises of how to reset the program on a Bosch dishwasher or another model. Cancellation is simple - just press the Start button and hold it for 3 seconds. The indicator lights should go out. After turning off the dishwasher, it will begin draining water. This happens within about 1 minute. But it happens that there is a problem with the dishwasher. Error codes start flashing on the display. In this case, you also need to know how to reset the settings.

Let's start by checking the sensor in the pan

In this paragraph we will tell you why it is important to check the sensor, even if you are sure and have made sure that there are no leaks. As mentioned above, the sensor is triggered by the rise of the float, and it can be raised not only by water, but also by debris or a foreign element that has fallen into the pan.

There are times when people transport washing machines from one place to another, as a result of which some small piece of plastic can fall off and hit the float, lifting it up. Then you just need to carry out diagnostics, understand the problem and remove all foreign objects from the pan. Most likely, after lowering the float, the E23 code will disappear by itself.

Attention! In addition, debris can cause sensor failure. After all, whatever one may say, this is a technique, and any irritating component can slow down its operation.

Ultimately, the code may be displayed due to a short circuit, as a result of which the sensor burns out or the contacts connected to it break. This often happens when DIY repairs are attempted by DIYers, or simply as a result of a power surge.

We talked about situations that cause an error that are not related to leakage. They cause errors even more often than the corresponding problem codes. In any case, you must first inspect the pallet and then try to fix the damage.

Basic error codes and ways to solve them

Modern dishwashers are highly functional, including self-diagnosis. It prevents many serious breakdowns. Based on the error codes, you can track the status of the device. Each code has its own meaning and description. Different manufacturers have their own indicators.

There are several general categories. Errors are classified according to them:

• electrical failures;
• problems with water heating;
• malfunction of sensors and switches;
• problems with filling/draining water.

Typical faults

If the machine gives an error, then there is probably one of the following typical situations:

• the appearance of water under the machine;
• failure to turn on the device;
• poorly washed dishes;
• no water heating;
• no drying of dishes;
• loud noise during operation.

The washing program is stuck

While the dishwasher is operating, various errors may appear. Experts say the most common problem is that the washing program freezes. Which is why you need to switch the program, that is, reboot it. Many errors have codes, the decoding of which can be easily found in the instruction manual. Brief data is displayed directly on the display.

The control module program describes system failures. This allows the machine to perform self-diagnosis and alert you to various problems. Often the error does not disappear even if the device is turned off/on or rebooted. In this case, there is no choice but to determine the cause and eliminate it completely.

Program freezing is caused by a number of reasons. But often this happens because the user does not perform periodic cleansing and prevention. As a result, the filters become clogged, the sensors are triggered and the control module blocks the functioning of the device components. Once the blockage is cleared, everything returns to normal.

Sometimes during work several errors of different types accumulate. They do not interfere with washing and are not considered serious. But after some time, the dishwasher may malfunction or not start and stop switching programs. And this is dangerous because more serious breakdowns will appear in the future.

In some machines, the old program can be reset in a certain way. First, the user opens the door and turns on the appliance. Then simultaneously press and hold program buttons 1+3 for 3 seconds. Afterwards the door is closed. Then it is opened again, and the dishwasher is unplugged. Press and hold the reset button for 3 seconds. Close the door again and wait for the signal to finish washing. After this, the door is opened and the machine is turned off.

There is an overflow of water

If the PMM overflows water, this may indicate:

• violation of installation rules;
• intake valve malfunction;
• illiterate connection;
• breakdown of the water level sensor;
• control module malfunction.

Sensor operation

Before you figure out how to cancel the program in the Bosch Silence Plus, SMV D RU, SMV EX R, SP, Supersilence dishwasher, as well as Electrolux ESL LO, Siemens, you need to study the operation of the sensors. Sometimes there is a malfunction in their work.

Let's look at the error codes using the Bosch Super Silence machine as an example:

• E6 (F6). Appears when the water level sensor and its flow control for the sprinkler fail.
• E15 (F15). Occurs when there is a water leak. Happens only in models with the Aquastop system.
• E14 (F14). Triggers if the water control sensor fails and does not respond to commands from the electronic unit.

The dishwasher is electrocuted

This is a rare problem, which indicates that the electric heating element is not broken, but there is a hole. It occurs due to long use, manufacturing defects or very hard water. Diagnostics and repairs are performed at the service center.

Coding of blockages in the drain system

Many malfunctions of Bosch occur due to their improper use - for example, before washing the dishes are not cleared of food residues. In particular, untimely cleaning of filters leads to the stoppage of the PMM operation. The table below shows defect codes, their descriptions and reasons for their occurrence.

These breakdowns are the result of improper maintenance of dishwashers. This is untimely cleaning of filters and unwillingness to clear dishes of food waste before putting them in the dishwasher.

Showing common error E22 on the display

The video demonstrates what actions need to be taken to eliminate the cause of the E25 code appearing on the Bosch PMM display:

Emergency actions if an error occurs in the dishwasher

All methods of handling the dishwasher are described in detail in the instructions. There is not always time to choose and think for a long time about what actions to take. In such situations it is necessary to interrupt the program. To do this, turn off the device for 20 minutes or press the Start button for 15 seconds. After this, they begin to understand the cause of the problem.

If the breakdown is simple, for example, the water drain hole is clogged and the PMM has not completed the program, then you can fix it yourself. In the first case, the drain is cleaned, in the second, the program is restarted. But there are situations when the reason is completely unclear. This requires the help of a master.

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.
