In most cases, Bosch CMAs have the function of displaying error codes in the event of a breakdown or sudden failure during the washing process. In certain situations, the user is able to fix the problem on his own without contacting a service center for help. One such example is error f04 in a Bosch washing machine, the meaning of which and solutions will be discussed below.
How to decipher error code f04
As a rule, the user does this intuitively. The problem is that error f 04 on the Bosch SMA reports quite obvious breakdowns that can be diagnosed visually.
In most cases, the appearance of this code is accompanied by a puddle formed under the Bosch washing unit, which is simply impossible not to notice. All that remains is to determine exactly where a leak has occurred. Sometimes only an experienced specialist can answer such a question, since not every user can independently detect damage.
The main reasons for the appearance of fault code f04
- Sharp metal objects get into the washing machine tank. Wedged between the drum and the tank, they cause damage to the walls of the latter. In older models, the tanks used to be made of metal material, and this problem did not have significant consequences. But today, for the manufacture of washing mashine tanks, plastic is used, which is less durable;
- defect admitted by the manufacturer. This is an insidious reason that can manifest itself after a certain time. It may be related to pipe, a pump and even a tank that can crack along the seam area;
- The water intake hose is damaged. It constantly experiences pressure created by water pressure. Any minor damage can cause a leak;
- The garbage filter is not screwed in tightly enough. This element needs regular cleaning, and sometimes it is not screwed into place very carefully, and liquid begins to seep through the remaining gap;
- a clogged washing powder tray can also cause a leak;
- damaged rubber cuff loading hatch.
How to reset error f 04
We found out what error f04 means. Now let's try to figure out what to do if a similar problem arises. First, it is recommended to check all the basic elements Bosch washing machine, to identify the likely location of the leak.
Water intake hose
It is checked for damage that could cause a leak. If the integrity of the element is not in doubt, the place where it is connected to the washing machine is inspected.It is likely that the gasket has worn out and will have to be replaced with a new one.
Drain filter
It is possible that the next time you clean the filter, you did not install it properly in place, not tightening it all the way along the thread. In this case, eliminating error f 04 is quite simple - the filter is unscrewed and installed again.
Metering tray and hopper
If traces of leakage are observed on the front panel of the Bosch washing machine, the problem should be looked for here. The compartments of the tray are filled with washing powders and are poured rinse aid, increasing the likelihood of blockages. In this case, the dispenser must be pulled out completely and the locking element must be pressed to remove the tray from the washing machine. The element is washed under running water and installed in place.
It happens that a leak occurs due to strong water pressure entering the dispenser. In this case, it is necessary to adjust the flow, reducing the pressure. All that remains is to activate the washing machine and check whether error f04 occurs or the problem is solved.
Loading hatch seal
If the cuff is worn out or damaged, water begins to leak from under the hatch of the washing machine, creating a puddle. To replace the element, you will need to open the washing mashine door, pull out the seal, and remove the fixing clamp. After this, the top cover of the Bosch machine is removed, and the mounting bolts securing the clamp are unscrewed. The cuff is released and can be replaced with a new analogue, proceeding in the reverse order.
Pipe branch
Bosch washing machine parts are in good condition, but the screen still shows error f04? It remains to check the fastening of the pipe. If this is the problem, the element is dismantled and dried. When installing it, glue should be used.Sometimes situations arise that the problem lies in the fluid inlet pipe. In this case, to perform the replacement, you will have to remove the top panel of the machine.
Repairing damage to the tank
Even it can get damaged, which can only be eliminated by completely replacing the element with a new analogue.
Conclusion
We looked at the main ways to fix error f04.
