If your cleaning equipment Bosch when provides an F21 error as well as does not knock out the plugs at the very same time, you are extremely lucky. Having actually seen this failing, promptly detach the Bosch cleaning equipment from the keys. Just then call an expert. Self-search for a trouble service, particularly in a powered method, enhances the danger of electric shock. Nevertheless, we will certainly not daunt you in advance, allow’s deal with this mistake step-by-step.
Analysis as well as description of the F21 code of the Bosch cleaning device
Mistake F21 in the Bosch cleaning maker might show up not only in the kind of alpha-numeric code. Typically it happens as a collection of blinking indicators on a control panel This takes place since some versions of Bosch cleaning makers are not geared up with a screen. Thus, the F21 code can not be revealed.
You can identify dozens of errors using the system of blinking indications. Professionals do it even without believing as they have a great deal of experience with such tools. A user can also do this following an unique table of error codes.
Aware below we verify just how the F21 code is revealed on the Bosch appliance without a display screen. The complying with stages happen. The cleaning device freezes and stops replying to switch presses. Then, it transforms the program selector knob. Three light bulbs start to flash or blink at the very same time (1000 revolutions, 800 transformations, and also rinsing). If you have an older model of the washing equipment, after that the indications of 800/600 changes and also washing will switch on. Older devices perform rotating at eight hundred revolutions, the optimum.
The mistake explanation is straightforward. Yet discovering the reasons for its incident is fairly complicated. Masters analyze the F21 error code the next means. There is no opportunity to rotate the drum of the Bosch cleaning machine. In fact, the appliance attempts to start the rotation several times. And if it does not be successful, the code F21 shows up on the control board. So what triggers the code appearance? Why the washing machine can’t begin the rotation of the drum?
Tacho sensor is defective A module doesn’t get information about the engine rate. So, it quits the Bosch cleaning maker and provides the F21 error code.
The engine is out of order. If the motor is damaged, it is not able to turn. Accordingly, the module makes a number of efforts to start the engine. After that it issues the defined error.
A chain which powers the electric motor or a Hall sensing unit (tacho sensing unit) is damaged. In this case, the sensing unit and the motor remain in order, but their feeding circuitry is broken or rather oxidized.
The reason for the F21 mistake can be a foreign object. It typically gets the storage tank during cleaning and hinders the drum.
An additional reason for F21 error code is a voltage decrease in the mains.
Hall sensor (Tachogenerator tacho sensor) is faulty.
Tacho Generator tacho sensing unit Hall sensor within electric motor Bosch washer
Tacho Generator tacho sensor Hall sensing unit within electric motor Bosch washer
There are no universal dishes for troubleshooting. It’s necessary to begin checking all the above factors in a practical order. Do it till you stumble upon a failure.
Allow’s start with the Hall sensing unit. Probably, you try to pick a various order, from straightforward to made complex. Naturally, it is fairly sensible. As an example, it’s a great idea to examine the rotation of the drum for foreign things first. Then check the voltage generally and also only after that enter into the instance to check the engine and the Hall sensing unit.
Several individuals get troubles acquiring accessibility to the tacho sensor as well as the electric motor of the Bosch washing equipment. Just how to reach these information?
Gradually turn off the gadget and draw it out someplace, where is a lot more space.
Take apart the back wall surface of the washing device body. Next off, remove the transmission belt due to the fact that it will certainly prevent your work.
Utilizing your phone, take photos of the cords as well as fasteners area in order not to mix it up later. Then get rid of the engine.
If you wish to promptly eliminate the electric motor from the Bosch washing equipment, do the adhering to. Firstly, disconnect the terminals from it. After this, loosen the tightening bolts and press the body of the part. Slightly move it forward as well as pull down.
The tacho sensor lies on the engine instance, so remove it and also carefully examine. There might be marks of oxide as well as oil on the internal surface of the ring of the tacho-sensor. Eliminate it. Next, take the multimeter and also inspect the Hall sensing unit. In case it turns out that the tachogenerator is burnt, you need to transform the component instantly.
Cleaning equipment electric motor Bosch
The Bosch cleaning equipment is frequently «marked» of severe engine issues. The problem with the brushes is the simplest point that can take place to this part. Brushes on collector engines are removed quite often. So, their replacement for the master is an usual point. An amateur may have some difficulties when handling brushes. Yet anyway this fixing comes from the group of simple breakages. So you will have the ability to fix it with your own hands.
It will be a lot worse if the electric motor provides a leak existing to the real estate. Or it has actually punctured numerous turns of the winding. In 99% of situations, you will certainly need to change the motor totally. At the very least, it will certainly be cheaper than the reconstruction of an old engine. If there is no leakage, examine each turn of the winding, trying to discover the rupture. The work is quite painstaking, yet it will certainly permit you to figure out exactly whether the engine remains in order or not.
Various other malfunctions
Prior to we proceed to other malfunctions that cause the F21 code, allow’s find exactly how to reset the error of the Bosch cleaning device. What is the factor to reset the failing if when it comes to its elimination it disappears? It’s an usual question. We’ll discuss every little thing to you now. The factor is that the mistake will not vanish also if you carry out the fixing correctly. If you do not drop the settings, the code will certainly still be below and also impede the start of the equipment.
Exactly how to reset a mistake of the Bosch cleaning device?
Transform the program selector to the off placement.
Transform the selector to the spin. At this phase, you need to wait up until the mistake shows up again on the control panel.
Press and also hold the switch in charge of switching over the transformations of the drum. Hold it for a few secs and after that launch.
Transform the program selector to establish the «drainpipe» setting.
Press on the button of turns changing once more as well as wait some secs.
If all the lights blink and also the equipment is making the loud noise, the mistake is reset. However if nothing happens after you launch the spin switch for the last time, after that you require to duplicate the above-described actions.
Some foreign item can trigger the F21 error code in Bosch washers. It often gets involved in the tank, which is taken into consideration to be rather a typical situation. It appears like masters have actually currently drawn out every little thing from the cleaning devices storage tanks. As an example, coins, pins, bones from bras, buttons, tiny details from kids’s toys, and so on
. All this stuff postures a risk for cleaning machine information. For instance, there were some situations when sharp things obstructed in between the container as well as the drum. It brought about puncturing the tank and leakage.
Exactly how to see to it that the drum jams the foreign object and do not take down the cleaning maker? It is essential to open up the hatch door of the formerly separated appliance. Attempt to transform the drum by hand. If you hear a metal rattle, and the part jams while rotating, then something has actually hit the container. An international things has to be instantly eliminated.
If the Bosch washing machine rejects to function as well as shows the F21 code, it’s time to take radical measures. The mistake may be caused by international item damages. Furthermore, it happens because of a solid voltage drop in the power grid. Or else, when such a decrease can stress out all the electronics of the device. And also it will precisely send your «assistant» to the garbage.
To summarize, the F21 mistake code of the Bosch washing maker is a common issue. The mistake’s factors are diverse. We tried to explain one of the most typical of them.
