Malfunctions of the Bosch Maxx 5 washing machine (Bosch Max 5): codes, diagnostics, repair

Service test Bosch Maxx 4

During the operation of German Bosch machines, malfunctions occur less frequently than with competitors; however, the manufacturer has equipped each Bosch Maxx model with a special service test, the so-called self-diagnosis mode, which can determine the performance of all system functions.
This function is very useful if several system components are broken. Launching the diagnostic mode is performed differently depending on the line: Bosch Maxx 4, Bosch Maxx 5, Bosch classixx 5, etc.

Let's look at the test using the Bosch Maxx 4 series as an example.

To start self-diagnosis of Bosch Maxx 4, turn off the machine. Simultaneously press the additional function buttons and turn the mode knob 30° clap. After a successful launch, you can begin selecting a test.

Bosch Maxx 4 programs comply with the following tests:

cotton 60° - check the electric motor;
cotton 60° economy - drain pump;
cotton 90° - heater;
spin - main valve;
drain - pre-valve.

To start the program on Bosch Maxx 4, press the “start” button. Faults are indicated by combinations of LEDs. In older Bosch Max models, error codes are displayed.

How to turn on the washing machine

Before starting work, you need to check the connection of the machine to the electrical network, prepare things for loading, having previously separated light, dark and colored laundry, which must be washed separately. The total volume of things must correspond to the nominal value of the unit: in no case should the drum be filled to the limit

Also pay attention to the fabric of the products; you can only wash items made from the same type of fabric at the same time.

Loading washing powder

Washing powder must be loaded into a special powder compartment, which usually consists of three compartments:

The left one is for the main wash.
The right one is for pre-washing.
Medium - for air conditioning.

This conditional distribution is typical for most brands of devices. If you want to clarify this information, please refer to the operating instructions specifically for your model.

Advice! When adding washing powder, it is important to follow the dosage indicated on the packaging. There is an opinion that the more powder you add, the better the quality of things stretch.

However, if there is an excess of it, the laundry, on the contrary, is poorly rinsed; stains and white stains may remain, which can subsequently affect the development of allergies.

Loading laundry into the drum

Before loading items sorted by color and material, carefully arrange them so that they do not lie in a lump. Thus, the washing and spinning process will be of better quality. After this, close the device door tightly.

Selecting a washing mode

The operating mode (program) is selected either by pressing a mechanical or touch button, or by rotating the switch, the pointer of which is directed to a specific mode. Some models of automatic machines combine both types of control.

The device can have the following washing programs, depending on the type of fabric and intensity:

fast;
careful;
delicate;
manual;
casual;
Clothing for babies;
cotton;
synthetics;
wool and others.

Modes and functions in the washing machine

Determining the washing temperature

The temperature range is set from 30˚C to 95˚C. Do not focus solely on choosing the maximum temperature; follow these recommendations:

the temperature is selected based on the degree of contamination of things; if you just need to refresh your laundry, just select a minimum temperature of 30˚C or 40˚C;
Synthetics are best washed at a temperature between 40-60˚C;
It is recommended to wash bed linen and bath accessories at maximum temperature.

Selecting the spin intensity of the laundry

The spin intensity is set by the number of revolutions per minute. The better the spin, the less moisture will remain in things, and they will dry much faster.

Important! For delicate items, you need to choose the minimum spin intensity. And especially delicate fabrics (silk, chiffon) are better not to be wrung out in the machine at all.

Starting the washing process

The automatic machine starts by pressing the “On” button. The cycle itself starts when you press the “Start” button, which, as we have already found out, can also combine the “Pause” function. If the process starts successfully, if there is an indicator, the washing time will be displayed on it.

Modern units are equipped with a delayed start function, which is very convenient. For example, you can set a time to turn on the device while you are away from home, so that your clothes have time to be washed when you arrive. Or you can set the start time to 5 am so that the washing machine will finish working when you wake up in the morning, and you can pull out the already clean clothes.

End of cycle

When the operation is completed, the device will stop and a corresponding sound signal will sound. After thirty seconds, the door lock will unlock and you will be able to remove the washed items. If the door does not open, this will indicate some kind of breakdown of the device.

For general care of your car, wipe the drum and rubber seal on the door frame with a dry cloth, as this is where a lot of water often accumulates. To dry the drum compartment and prevent the formation of mold and mildew spores, leave the door slightly open.

Bosch washing machine under warranty: what to do?

If a machine whose control board has broken is under warranty, then with a high degree of probability the cause of the malfunction is a manufacturing defect. The manufacturer Bosch provides a 1-year warranty on its household appliances.

To receive service, you must have a standard nameplate on the device. The manufacturer considers its removal as depersonalization of the equipment and a violation of the rules of use.

If a breakdown is detected, you must contact a retail outlet or a Bosch service center. You must have proof of purchase with you in the form of a check or receipt. They are needed to confirm the date of purchase of household appliances.

The service center is required to repair or replace the faulty control board free of charge during the entire warranty period. In this case, the consumer must be provided with a certificate stating that the machine was sent for diagnostics and repair. It states the date and time of the request, and also indicates the client’s complaints.

The manufacturer may refuse service in the following cases:

the machine was opened and an attempt was made to repair it outside the service center;
it will be proven that the cause of the breakdown is a violation of the rules for transporting equipment;
the manufacturer finds out that the malfunction occurred due to the user’s fault, due to improper handling of the device or for some other reason;
the board has burned out or been damaged by rodents and insects;
The malfunction occurred due to instability of the power grid parameters.

If the consumer does not agree with the refusal of warranty repairs, he needs to order an independent examination and go to court with its results.

Elimination of major machine malfunctions

After a thorough diagnosis, malfunctions of Bosch washing machines are strongly recommended to be eliminated as soon as possible. This will help extend the life of your household appliances.

Let's look at the Bosch Maxx 4 as an example. If the Bosch Maxx washing machine does not turn on, then you should first figure out whether this is due to faults in the wiring and its individual components, or whether the reason is in the device itself. First of all, the voltage in the network is checked. If it is, then the next step will be to check the power cables, sockets and circuit breakers.

The reason may be a faulty power button. If it sinks or does not move, it must be replaced. Less common reasons are failure of the main chip and control module of the equipment, breakdown of the electric motor or drum.

If attempts to troubleshoot a Bosch washing machine do not lead to stabilization of the operating process and startup, you must contact qualified specialists for further diagnostics.

Bosch Maxx 4 door malfunctions If depressurization occurs or the integrity of the rubber braid is damaged, you should replace it with a new one yourself or in a specialized service. The error code during normal operation may be cleared when the washing machine is restarted.
Problems with draining or supplying Bosch Maxx 4 water to the system. It is necessary to check the position of the supply and drain valves and open them. If the error continues to appear, the filters need to be cleaned and replaced. If the pressure in the system is too low, check and clean the pipes and replace the water level sensor.
Long-term drainage of Bosch Maxx 4 can be solved by replacing the water level sensor and cleaning the main pump.
Incorrect water heating , prolonged heating requires checking the thermostat, replacing the heating element, and temperature sensor.
Damage to the drum can be eliminated by loading the correct amount of laundry - frequent overloading leads to abrasion of the belts and complete failure of the unit.

Errors associated with partial collection of detergents in Bosch Maxx 4 or Bosch Maxx 6 can be eliminated by cleaning the container. To prevent such malfunctions of the Bosch washing machine, do not load too much powder and leave it inside the machine for a long time (especially important if the device is built in a damp room).

The presence of noise during operation of the Bosch Max device must be diagnosed more carefully. If the noise is periodic and appears at the beginning or end of the operating cycle, then the cause is the presence of foreign objects in the corrugated pipes. It is necessary to remove them as quickly as possible to avoid penetration into the system and the occurrence of short circuits and depressurization of individual elements.

If the noise resembles a metal grinding sound, then this indicates a bearing failure. Quickly replacing them with working ones can prevent complete failure of the electric generator.

Preventive measures

Washing machines, like any household appliance, sometimes break down. But with proper care and operation, the machine will last longer than usual without malfunctions.

In order for the device to last longer, you must follow certain rules that many washing machine owners ignore:

Before loading items into the drum of the machine, you must carefully check all pockets. If this is not done, small objects may get into the tank of the machine. This may cause blockage or malfunction.
Do not overload the washer. However, it’s also not worth driving it idle. Load a medium amount of items into the machine drum. If you follow this rule, the drive mechanism and electric motor will last longer.
Use your Bosch washing machine at least once a month. Leaving the equipment idle for a long time will cause its rubber bands to fail.
Do not pour excessive amounts of washing powder into the detergent drawer. Excess powder will clog the pressure switch tube and pipes. And this will cause a malfunction.
If possible, it is necessary to purchase a voltage stabilizer and connect the machine to the electrical network through it. This way you can protect the electronics of the washing machine from possible breakdowns.
After each wash, you need to wipe the hatch cuff with a cloth. The same needs to be done with the powder receptacle. The hatch must be left open. The detergent drawer must be pulled out. You should also drain the remaining water to prevent it from stagnating.

How to properly reboot the machine

Before restarting the product, carefully study the instructions for your particular washing machine model, since each brand of machine has its own design features and certain methods for urgent stopping. We will look at general recommendations for properly rebooting the machine.

How to stop the program: options

Most washing machines have two unified options for urgently resetting the installed program.

First option

Healthy! If water has already accumulated in the washing machine, drain it manually using the drain filter (a small hatch at the bottom of the machine).

Second option

By pressing the "Start/Pause" button, the program is completely reset. In this case, turning off is not done by pressing it once, but by holding the button for a long time (5-6 seconds). Further events will develop depending on the modification of your device:

Why do you need to reset the program correctly?

Many users believe that the problem of urgent work stoppage can be solved by simply disconnecting the device from the electrical network. Yes, this will allow you to turn off the washing machine, but the previously selected mode may not be reset, since often automatic machines “remember” the last settings and will start them again after turning them on. In addition, due to a sudden disconnection from the network, an important part of the unit - the control board - is at high risk of breakdown.

If the power is out

In the event of a sudden power outage, first of all, disconnect the device from the network. To do this, you need to remove the cord from the outlet so that the washing machine is not subject to a sudden voltage drop.

When the power supply is restored, plug the device into the mains. If the previously installed program has not been reset, the automatic machine will simply continue to operate. Some models will drain the water when turned on and stop washing. In this case, you will need to select the desired mode again and start it.

Internal failure

If the unit suddenly fails, it is necessary to find out what kind of problem arose: software or mechanical. If the software fails, the control panel is locked and the buttons do not respond to pressing. Try unplugging the machine for 15-20 minutes to reboot the control unit, then turn it on and try to run the program again.

Recommendation! To return the automatic machine to its factory settings, you may need the help of an electronics technician; do not try to cope with this task yourself without the appropriate training.

Signs of a control module failure

It is not difficult to guess that the electronic module in a Bosch washing machine has broken down. Signs of malfunction:

The machine doesn't work. It does not turn on at all, or does not respond to commands. This is the most dangerous sign, as it indicates 100% failure of the part.
The device turns on, one of the following codes appears on the screen: F00, E00 - firmware failure, F67 - control board failure.
If individual tracks on the module burn out, any other code may appear. It will correspond to the element whose operation is controlled by the faulty part of the board.
The program starts, but it crashes, after which the cycle starts over. This can happen an infinite number of times.
The water does not heat up or gains temperature very quickly.
The water is drained and collected in the drum, but the wash does not start.
The drum rotates quickly or slowly.

These are the most common signs of a board malfunction, indicating its failure. However, you should not panic; first you need to eliminate the possibility of its one-time failure. The machine is restarted by holding down the “Start” button for 5 seconds.

After turning off the device, leave it alone for 15 minutes and then turn it on. If the error code appears again or the machine continues to operate abnormally, repair is required.
