The problem when the Bosch washing machine does not switch from washing to rinsing, most often indicates a malfunction of the intake valve of the water supply or clogging of the filter-mesh. At this point, the drum may remain dry or, conversely, overflow, and the program timer freezes at one stage, preventing the signal from moving to the next cycle. Electronic control module Siemens or Bosch blocks further actions, waiting for the fulfillment of conditions on the level of liquid, which creates the illusion of a complete stop of the device.
In some cases, the cause is the failure of the pressostat, which incorrectly reads the water level in the tank and sends false data to the control system. If the pressure sensor is βslippedβ or its tube is clogged with powder plaque, the machine simply does not understand that it is necessary to drain dirty water and dial clean. No accurate signal of completion of the main cycle laundry It cannot be completed programmatically.
In addition to hydraulic nodes, it is worth considering the likelihood of a software failure or a voltage surge that led to the βhangβ of the controller. Often users notice that the indicators are on, the engine is buzzing, but the transition to the next stage does not occur. In such a situation, a consistent check of electrical circuits and mechanical components is required to avoid costly repairs to the control module.
Failure of the intake water supply valveh2>
One of the most common reasons why Bosch washing machine does not go to rinse, is the failure of the electromagnetic valve. It is this node that is responsible for opening the water supply from the water pipe to the tank after draining the dirty liquid. If the valve coils are burned out or the voltage has stopped flowing on them, the water simply does not flow, and the machine endlessly waits for the tank to fill.
Inside the valve are solenoids, which under the action of current shift the membrane, opening the way to water. Over time, the coils may form oxidation, contacts burn, or there is a breakdown of the insulation. As a result, even if the control module sends an βopenβ command, the physical mechanism remains closed. Diagnosis of this part requires a multimeter vertebrae for resistance of the windings.
How to check the valve multimeter
To check, it is necessary to remove the upper cover of the machine, disconnect the wires from the valve and measure the resistance of each coil. The normal value varies from 3 to 4 kΞ©. If the device shows infinity or zero, the valve is defective and requires replacement.
It is also important to consider that the valve may be partially serviceable, but mechanically blocked by lime plaque. Hard water leads to the fact that the moving parts of the mechanism overgrown with sediments and lose mobility. In this case, even the working electrical signal will not be able to start the process of water intake for the rinse.
- π Breaking or burning out of the solenoid electric coil.
- π§ Mechanical jamming of the rod due to scale and rust.
- β‘ No tension on the contacts due to wiring problems.
- 𧱠Clogging of valve inlets with small debris.
Filter clogging and pressure problems
Often the reason for stopping before rinsing is banal - filter elements are clogged. At the entrance to the intake valve, a small mesh is installed, which traps sand and rust from the pipes. If it is completely clogged, the water either does not come at all, or flows in a very weak stream, because of which the machine does not have time to gain the desired volume for the time allotted by the program.
In addition to the external filter, it is important to check the internal circulation system and the tube going to the air. pressostat. If a water plug has formed in this tube or it is clogged with powder porridge, the pressure sensor will not be able to correctly track the water level. The machine may think that the tank is full when it is empty, or vice versa, that there is no water, although the tank is full.
Before calling the master, always check the water pressure in the tap. If the pressure is weak, the machine may not start the rinse mode simply because of a lack of pressure in the water supply.
Particular attention should be paid to the condition of hoses and pipes. Cracks, inflections or microscopic holes can disrupt the tightness of the system, leading to a drop in pressure. In such cases Bosch It can be an error or simply stop the cycle, fixing the inconsistency of parameters.
| Element of the system | Symptom of blockage | Elimination method |
|---|---|---|
| Intake filter | Water does not enter or flows in a thin stream. | Flushing with a tap brush |
| Pressostat tube | Misdefinition of water level | Blowing and washing with warm water |
| Drain filter | Residues of water in the tank after draining | Cleaning of coins, threads and garbage |
| Powder dispenser | Poor washing of detergent | Dismantling and mechanical cleaning of the tray |
Water level sensor (pressostat) and its malfunctions
The critical node, without which the transition to the rinse stage is impossible, is the pressostat. This sensor tells the electronic module how much water is in the tank. If it fails, the machine simply wonβt receive the βwater dialedβ command and wonβt start the engine to spin the drum at the new stage.Pressostats are mechanical and electronic. In mechanical models, a common problem is sticking the contacts inside the housing or loss of elasticity of the membrane. Electronic sensors can give incorrect readings due to oxidation of contacts or damage to wiring. In both cases, the logic of the machine is broken and the washing cycle is interrupted.
Checking the operability of the sensor often involves blowing the tube with the mouth (when the machine is disconnected) - characteristic clicks should be heard. If there are no clicks, or they occur incorrectly, the part must be replaced. It is also worth checking the integrity of the tube itself, as even a small cut will lead to air leakage and false readings.
- π Sticking of the contact group inside the sensor.
- π¬οΈ Violation of the tightness of the air chamber or tube.
- π Oxidation of contacts in the connection connector.
- βοΈ Displacement of the adjusting screw (in older models).
Failures in the electronic control module
The most expensive reason why a washing machine Bosch does not switch modes, there may be a malfunction of the control board. The chips and simistors responsible for switching valves can burn out due to a voltage surge in the network or moisture. In this case, the command to open the valve is not physically formed.
Often users face βglitchβ firmware when the program hangs in the loop. This can happen after a sudden power outage during washing. In such cases, a full reboot helps: disconnect the machine from the network for 15-20 minutes. If the problem recurs after inclusion, most likely, a reflash or repair of the board is required.
β οΈ Warning: Self-repair of an electronic module without special knowledge and equipment can lead to the final failure of the equipment. If you are not sure of your abilities, it is better to contact the service.
It is also worth checking the integrity of the plumes connecting the module with actuators. From vibration, contacts can move away, oxidize or rub. Poor contact in the intake valve control circuit will create a situation where the machine "does not see" the valve and does not apply voltage to it.
Diagnostics and inspection of the drain system
Before water starts to be collected for rinsing, the machine must completely drain the dirty water after the main wash. If the drain has not passed to the end, the water level sensor (pressostat) will fix the βexcessβ liquid and prohibit the start of the next stage. Therefore, the problem may lie not in the set, but in the quality of plum.
βοΈ Checklist for drain checklist
The drain pump (pump) may work poorly due to winding threads on the impeller or wear of bearings. A honky but non-pumping pump is a sure sign of mechanical locking. It is also worth checking whether the end of the drain hose is lowered too low - this can lead to spontaneous water draining during washing, which confuses the logic of the program.
A common mistake is to ignore cleaning the pump filter. Coins, buttons and pile are there to create a serious resistance to the flow of water. The machine tries to drain the water, the timer expires, and the program gets into error, and without reaching the rinse.
- π Blocking the impeller pump with foreign objects.
- π Burning out of the drain pump winding.
- π Clogging of corrugated water connecting the tank and the pump.
- π High location of the drain point in the sewer.
Programming errors and resetting settings
Modern washing machines Bosch They are equipped with complex electronics that are sensitive to voltage drops. A software failure can cause the machine to βforgetβ where it stopped. In this case, the procedure for resetting errors and restarting the program helps.
To perform the reset, you need to turn off the machine, disconnect it from the power grid for 15-20 minutes. After turning on, try running the "Plum" or "Grinse" program separately. If the machine executes these commands, then the mechanical part is in good working order, and the problem was the software freeze.
If after the reboot the machine again freezes in the same place, the problem is hardware in nature and requires replacement of parts.
Some models require a combination of buttons to enter diagnostic or reset mode. This information is usually contained in the user's instructions. If the machine is constantly giving out an error code (e.g. E18, F18 or similar for your model), decrypting that code will give you an accurate answer as to which node needs attention.
When a Master's Challenge is Necessary
If simple methods like filter cleaning and rebooting have not helped and the washing machine still doesnβt go rinsing, replacement components are likely required. Replacing the intake valve, pressostat or pump requires disassembly of the body and the availability of tools, which is not possible for every user.
A particularly difficult case is the malfunction of the control module. Here you need not just a replacement of the part, but also the correct setting, and sometimes soldering of elements on the board. Inept intervention can lead to short circuit and damage to other parts of the machine.
β οΈ Note: Do not ignore the repeated car stops. Operation of equipment with a faulty valve or sensor can lead to water leakage and flooding of neighbors.
Calling a specialist is also justified if the car is on warranty. Self-repair in this case cancels the manufacturer's warranty obligations. The wizard will conduct a full diagnosis using professional equipment and accurately determine the cause of the failure.
Frequently Asked Questions (FAQ)
Why does a Bosch machine draw water and stop before rinsing?
Most likely, the intake valve is defective or its filter is clogged. The machine cannot get the required amount of water in the allotted time and interrupts the cycle. The water level sensor may also fail.
Can I start the rinse mode manually if the car is hovering?
Yes, in many Bosch models you can choose a separate program "Grinse" or "Plum". This will help complete the cycle and take out the linen, but will not solve the underlying problem of the malfunction.
What does the flashing indicator of the door lock mean when you stop?
A flashing lock usually indicates an error related to water level or drain. The car locks the door, as there may be water in the tank. The drain filter and pump must be checked.
How often should the washing machine filters be cleaned?
The intake filter is recommended to be checked every 3-6 months, and the drain filter - every 1-2 months, depending on the frequency of washing and hardness of the water.
Can low pressure in the plumbing stop the car before rinsing?
Yes, if the water pressure is too weak, the machine will not have time to gain the required volume in the time interval allocated by the program and stop the process, issuing an error.
