The situation when Bosch washing machine stops pressing clothes at high speeds, familiar to many owners of this popular German equipment. Instead of dry things, you get a wet mass from the drum, and the display may light up alarm codes or there is no indication of the completion of the cycle. This is not just an inconvenience, it is a signal that one of the units of the unit is working incorrectly or completely out of order.
Before calling the master, it is necessary to conduct a primary diagnosis, since the problem can be hidden in elementary things that do not require disassembly of the body. Often users ignore the first symptoms, such as extraneous flushing noise or increased washing time, which eventually leads to more serious breakdowns of the electronics. In this article, we will discuss in detail why. Bosch washing machine It does not stop and how to locate the fault.
It is important to understand that modern models such as Series 4 or Series 6They are equipped with a complex self-diagnosis system. If the unit “realizes” that it cannot safely continue the spin cycle due to imbalance or drain problems, it forcibly stops the drum to prevent bearing damage or water leakage.
Checking the washing program and the pressing mode
The most common, but often occurring reason is a randomly chosen washing mode without pressing or with its minimum speed. In the lines Bosch Maxx and more modern series provides a function "Without pressing" or "Delicate washing", where the drum only slightly shakes off the water. Check the control panel: you may have inadvertently activated the Easy Iron or Crash Protection option, which leaves things wet.
It is also worth paying attention to the choice of the type of fabric. If you have set the wool or silk mode, the unit automatically limits the speed of rotation of the drum to 400-600 rpm, so as not to damage the structure of the fibers. In this case, the technique is good, just the algorithm does not imply aggressive centrifugation.
- 🔄 Check if the “No Spin” button is in the active position.
- 👕 Make sure that the program you choose supports high speeds.
- ⏱️ Pay attention to the remaining time: if it is “hanging” and does not decrease, the machine cannot move on to the next stage.
Sometimes the failure occurs in the electronic control module, which “forgets” user settings. Try restarting the device: turn it off the socket, wait 15-20 minutes and run the short cycle again. If the problem happens again, it is not a matter of settings.
Problems with draining water from the tank
One of the most likely reasons why Bosch washing machine It does not squeeze out the linen, it is impossible to completely pump water from the tank. The logic of the controller is simple: if the water level exceeds the permissible threshold, the launch of high spins is prohibited in order to avoid hydraulic shock and damage to the hatch cuff. In such cases, the error code often appears on the display. E18 or F18.
The first thing to do is check the drain filter located in the lower right part of the case behind the decorative panel. It is there that coins, buttons, pile and thread get, which eventually form a dense plug. Before unscrewing the filter, be sure to splash the cloth and prepare a flat container, as residual water will leak out of the hose.
⚠️ Before unscrewing the drain filter, make sure that the machine is disconnected from the power grid and the water inside the tank cools if there was was washing at high temperature before.
If the filter is clean, the problem may lie in the drain hose. Check it along the entire length: there are no clogs, transferred areas or blockages at the connection point to the sewer. Often users forget that the lift height of the drain hose also matters – if it lies on the floor, the water can go away by itself, but the pump will not be able to create the right pressure to pump quickly before pressing.
☑️ Diagnostics of the drainage system
Failures of the drain pump (pump)
When mechanical filter cleaning does not help, the probability of failure of the filter itself should be considered. drain-pump. A pump is an electromechanical device whose life is limited. Over time, the bushings wear out, the impeller can crack from hitting solid objects, or the winding of the pump engine burns. In models Bosch Classixx and Logixx There are different types of pumps and replacing them requires partial disassembly of the body.
Diagnosing a malfunction can be heard. Start the "Plum" or "Push" mode. If you hear a buzz but the water doesn’t go away, or the pump makes a crack and whistle, it’s likely to need to be replaced. It is also worth checking the contacts going to the pump: oxidation or burning off of the wires often leads to the fact that the control module does not see the pump and blocks the cycle.
The table below shows the main symptoms and possible solutions for drain problems:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The pump is buzzing, the water is not going away | Impergence or jamming | Cleaning or replacing the pump |
| Total silence on the drain | Chain break or burnt-out | Multimeter check, replacement |
| The drain is going very slowly. | Overgrowth of pipes or wear of the pump | Cleaning the system, replacing the node |
| E18 error on display | The plum problem (time-out) | Comprehensive drainage test |
If you have made the decision to replace the pump yourself, remember that in some models access to it is possible only through the bottom or requires removal of the front panel. Always use original parts or quality counterparts, as cheap Chinese pumps often have a back shaft, resulting in quick re-incapacity.
Wear of electric motor brushes
If you Bosch washing machine does not gain momentum for spinning, but the water merges normally, and the drum rotates at low speeds (for example, when washing), then the graphite brushes of the engine were worn with a high degree of probability. This is an expendable material, which, when rubbed against the collector, gradually wears off. When the brush length becomes critically small, contact is lost and the engine cannot develop the power needed for centrifugal pressing.
Symptoms of brush wear often appear gradually. First, the machine can stall when trying to sharp set speed, sparks may appear (seen through the hatch if it is transparent, or a characteristic crackle is heard), and then the spin mode simply stops starting. Electronics detects the rotor rotation desynchronization and blocks the program.
Can I replace the brushes myself?
This is one of the most common repair procedures. You will need to remove the engine, get to the brush holders, carefully remove the old graphite rods and install new ones. It is important to wipe the brushes to the collector, starting the engine at low speeds without load. However, if the collector has deep swelling or furrows, simply replacing the brushes will not help - grinding or replacing the engine will be required.
Replacement will require removing the engine, which in front-load models is usually done through the rear wall or, in some cases, through the bottom of the body. Pay attention to the condition of the collector: if it is blackened or has deep furrows, simply replacing brushes may not give a long-term effect. In that case, critical The condition for restoring operability is professional flow of the collector or replacement of the entire motor.
Failure of the TENS and problems with grounding
What is the connection between water heating and water heating? But in the washing machines. Bosch (as in many other) a breakdown of the TEG on the body can lead to a leakage of current. The control module, fixing the potential on the tank body or engine, can go into protection mode and block the execution of energy-intensive operations, such as spinning. Also, this is often accompanied by knocking traffic jams or ultrasound in the apartment.
Diagnosing a TEN breakdown can be done using a multimeter in resistance measurement mode. One probe is placed on the contact of the TEN, the other on its metal body (or central stud). The device should show infinity. If there is any resistance, the heating element should be replaced immediately.
In addition, a faulty TENG can give incorrect readings to the temperature sensor, because of which the machine “thinks” that the water is still hot, and does not go to press, waiting for cooling, or vice versa, blocks the cycle due to overheating. In some models, when the TEN is burned, the machine can freeze at the heating stage and not go to rinse and press.
When replacing the heater, always change the rubber gasket (cuff) of the heater. Old rubber after removal often deforms and will not provide tightness, which will lead to leakage.
Control module and sensor malfunctions
The most difficult and expensive option is the failure of the electronic control module or sensors. If Bosch washing machine It does not squeeze out because of the “glitch” of the brain, then repair requires qualification. Often burn simistors, controlling the engine, or tracks on the board. Also, the problem can create a tachogenerator - a sensor that controls the speed of rotation of the engine. If it is contaminated or damaged, the module does not receive the speed data and stops the machine.
A water level sensor (pressostat) can also give false signals about the presence of water in a tank, even if it is empty. In this case, the machine will endlessly try to drain the water or just stand waiting for the readings to change. Checking the pressostat involves removing the tube and purging, as well as vertebrating contacts.
⚠️ Attention: Diagnostics and repair of electronic control modules require special knowledge and equipment. Do not attempt to repair the board yourself without experience, this can lead to a complete failure of the machine.
Sometimes the problem lies in the cliff of wires going from the engine or the thermal power plant to the module. Vibration during pressing for years leads to rubbing of insulation and contact groups. Visual inspection of wire harnesses often allows you to find oxidized or burned contacts, the restoration of which brings the technique back to life.
If the machine makes an error, write down its code. In Bosch models without a display, the code is often displayed by flashing indicators in a specific sequence (for example, flashing wash and rinse indicators).
Laundry imbalance and overload
Modern machines Bosch function AquaStop The vibration protection system is very sensitive to the weight distribution in the drum. If you load one heavy thing (such as a wet blanket or plaid) or vice versa, too many small things that are lost in a coma, the vibration sensor will detect a strong imbalance. The machine will try to fluff the underwear by twisting the drum in different directions, but if this does not help, it will reset or stop so as not to break the bearing assembly.
The solution is simple: open the hatch, straighten the linen, add or remove things for an even distribution of mass. Also make sure that the machine itself is flat: leg adjustment is a mandatory procedure when installing. If the machine is on the floor unsteadily, even normal loading can be perceived by sensors as a critical imbalance.
Why doesn't the car pull one thing off?
One heavy wet thing (jeans, robe) sticks to one side of the drum, creating a powerful centrifugal moment. Sensors detect extreme vibration and emergency stop the pressing. Solution: Wash such things with others or use hand washing/delicate washing mode.
Frequently Asked Questions (FAQ)
Why is Bosch's washing machine buzzing but not pressing?
The buzzing in the absence of rotation of the drum most often indicates engine jamming, wear of drum bearings or malfunction of the starting capacitor (in older models). It can also be a sign that the engine is trying to start, but it is hampered by a foreign object caught between the tank and the drum.
What does the E18 error mean on the Bosch washing machine?
Error code E18 or F18) indicates a water discharge problem. The machine cannot pump water out of the tank in the allotted time. Causes: filter clog, hose overbending, malfunction of the pump or sewer pipe.
Can you use a car if it doesn’t work?
The car can be operated, but it is not recommended. Things will be too wet, which increases the load on the dryer or requires manual drying. In addition, ignoring the cause (e.g., drain problems) can lead to more serious breakdowns, such as combustion of the TECH or failure of the control module.
How to Reset an Error on a Bosch Washing Machine?
To reset the error, try to turn off the machine with a button, then disconnect from the network for 15-20 minutes. After turning on, start the program "Plum" or "Push". If the fault is fixed, the error will disappear. If the cause remains, the error will appear again.
