If your washing device Bosch once provides an F21 mistake and does not knock senseless the plugs at the same time, you are very fortunate. Having seen this failing, instantly disconnect the Bosch cleaning machine from the mains. Only after that call a specialist. Self-search for an issue remedy, specifically in a powered technique, increases the danger of electrical shock. Nevertheless, we will certainly not intimidate you beforehand, allow’s handle this mistake step-by-step.
Analysis as well as summary of the F21 code of the Bosch washing equipment
Error F21 in the Bosch cleaning maker may appear not only in the form of alpha-numeric code. Frequently it takes place as a set of blinking indications on a control panel This takes place since some versions of Bosch washing devices are not geared up with a display screen. Therefore, the F21 code can not be shown.
You can identify dozens of errors utilizing the system of blinking indicators. Professionals do it even without thinking as they have a lot of experience with such devices. A customer can likewise execute this complying with a special table of error codes.
In the picture below we show how the F21 code is revealed on the Bosch appliance without a display screen. The following stages happen. The washing maker ices up as well as quits responding to switch presses. After that, it transforms the program selector knob. Three light bulbs begin to flash or blink at the very same time (1000 transformations, 800 transformations, and also rinsing). If you have an older version of the washing maker, after that the indicators of 800/600 transformations as well as rinsing will turn on. Older gadgets perform spinning at 8 hundred revolutions, the optimum.
The mistake explanation is simple. But locating the reasons for its event is fairly made complex. Masters analyze the F21 mistake code the next way. There is no opportunity to rotate the drum of the Bosch cleaning machine. Actually, the home appliance tries to begin the rotation several times. And also if it does not prosper, the code F21 shows up on the control panel. So what causes the code look? Why the washing maker can not begin the rotation of the drum?
Tacho sensor is malfunctioning A component does not obtain details regarding the engine rate. So, it quits the Bosch washing machine and also gives the F21 error code.
The engine is out of order. If the electric motor is broken, it is unable to rotate. As necessary, the module makes several efforts to start the engine. After that it issues the defined mistake.
A chain which powers the motor or a Hall sensing unit (tacho sensor) is damaged. In this situation, the sensor and the motor remain in order, yet their feeding electrical wiring is broken or instead oxidized.
The reason for the F21 error can be a foreign object. It frequently obtains the container during cleaning and hinders the drum.
One more factor for F21 mistake code is a voltage drop in the keys.
Hall sensor (Tachogenerator tacho sensing unit) is malfunctioning.
There are no universal recipes for repairing. It’s needed to begin examining all the above factors in a hassle-free order. Do it up until you find a malfunction.
Let’s begin with the Hall sensor. Most likely, you attempt to pick a various order, from straightforward to made complex. Of course, it is quite sensible. As an example, it’s a good idea to check the turning of the drum for foreign objects initially. Then inspect the voltage in the mains as well as only then enter the case to check the engine and also the Hall sensing unit.
Many users get problems acquiring access to the tacho sensor as well as the motor of the Bosch cleaning maker. Exactly how to get to these details?
Gradually shut off the tool and also draw it out someplace, where is a lot more space.
Take down the back wall of the washing equipment body. Next, get rid of the transmission belt due to the fact that it will certainly prevent your job.
Utilizing your phone, take images of the cables as well as fasteners place in order not to mix it up later. Then eliminate the engine.
If you wish to rapidly get rid of the motor from the Bosch washing maker, do the following. To start with, detach the terminals from it. After this, unscrew the tightening bolts as well as press the body of the part. Slightly relocate forward as well as pull down.
The tacho sensor is located on the engine situation, so remove it and also thoroughly evaluate. There might be marks of oxide and oil on the inner surface of the ring of the tacho-sensor. Eliminate it. Next, take the multimeter and also check the Hall sensor. In instance it turns out that the tachogenerator is scorched, you need to change the part promptly.
Engine problems
The Bosch cleaning maker is commonly “marked” of significant engine concerns. The issue with the brushes is the simplest thing that can take place to this part. Brushes on collection agency engines are eliminated quite often. So, their substitute for the master is a common point. An amateur might have some problems when dealing with brushes. But anyhow this repair belongs to the classification of easy breakages. So you will certainly have the ability to fix it with your own hands.
It will certainly be much even worse if the electric motor provides a leakage present to the real estate. Or it has punctured a number of turns of the winding. In 99% of instances, you will certainly need to transform the electric motor completely. At the very least, it will be less costly than the restoration of an old engine. If there is no leak, inspect each turn of the winding, trying to discover the tear. The job is fairly painstaking, however it will certainly enable you to figure out specifically whether the engine remains in order or otherwise.
Other breakdowns
Prior to we proceed to various other malfunctions that trigger the F21 code, let’s uncover how to reset the mistake of the Bosch washing machine. What is the factor to reset the failure if in the case of its removal it vanishes? It’s a common inquiry. We’ll clarify whatever to you currently. The factor is that the mistake won’t disappear also if you carry out the repair work appropriately. If you do not drop the settings, the code will certainly still be right here and prevent the begin of the maker.
How to reset a mistake of the Bosch cleaning maker?
Transform the program selector to the off position.
Turn the selector to the spin. At this stage, you need to wait until the error shows up once again on the control board.
Press as well as hold the switch responsible for switching over the transformations of the drum. Hold it for a few seconds and after that launch.
Turn the program selector to establish the “drain” mode.
Press on the button of turns changing again and wait some secs.
If all the lights blink and the equipment is making the loud audio, the mistake is reset. Yet if absolutely nothing happens after you release the spin switch for the last time, after that you need to duplicate the above-described activities.
Some foreign item can cause the F21 error code in Bosch washing machines. It frequently gets involved in the tank, which is considered to be quite a common circumstance. It appears like masters have actually already removed every little thing from the washing makers containers. For example, coins, pins, bones from bras, switches, little details from youngsters’s toys, etc
. All this stuff positions a danger for cleaning maker information. For instance, there were some instances when sharp items jammed in between the tank and the drum. It brought about puncturing the tank and also leak.
Just how to make certain that the drum jams the foreign things and also do not take apart the cleaning device? It is necessary to open up the hatch door of the previously detached appliance. Attempt to transform the drum by hand. If you hear a metal rattle, as well as the component jams while spinning, after that something has struck the tank. An international item has to be right away eliminated.
If the Bosch cleaning machine refuses to work and shows the F21 code, it’s time to take extreme measures. The mistake may be brought on by foreign item damages. Furthermore, it happens due to a solid voltage drop in the power grid. Otherwise, once such a decrease can wear out all the electronic devices of the tool. And it will specifically send your “helper” to the garbage.
To sum up, the F21 mistake code of the Bosch washing equipment is an usual problem. The mistake’s factors are diverse. We attempted to describe the most typical of them.
