Line of automatic washing machines Bosch Maxx 5 It is deservedly considered one of the most reliable and popular among household appliances of German production. These units, released more than a decade ago, are still actively used in many homes, demonstrating the enviable survivability of the main nodes. However, like any complex mechanism, they require proper care and timely diagnosis in case of failures.
Possession of such equipment implies an understanding of the basic principles of its operation, which will avoid expensive repairs in service centers. Electronic control system These models are able to self-diagnose, displaying or indicating the flashing of LEDs fault codes. Ignoring primary signals of water dialing or pressing problems can cause expensive components to fail, such as: electronic Or the engine.
In this article, we will discuss in detail the technical features of the series. WAE/WAS/WABThis is often referred to as Max 5. You will learn how to decipher alarms, what preventive measures will prolong the life of the device and whether to purchase a used model in the current conditions. Proper operation is a guarantee that your assistant will serve for many years to come.
Technical features and model range
Series Bosch Maxx 5 It covers a wide range of models, differing in the type of loading of linen, dimensions and set of functions. The main engine here is a classic collector motor with belt transmission, which has proven itself as a repairable and quite quiet unit. Unlike more modern models with direct drive, it uses a tank depreciation system, requiring periodic checks of the condition of counterweights and springs.
An important characteristic is the presence of a system. AquaStop (in most full-size models), which prevents flooding of the room when the hose breaks or the valve malfunctions. The design of the tank is usually made of durable plastic, not subject to corrosion, but sensitive to mechanical shocks during transportation. A unique feature of the early versions of the Maxx 5 is the ability to mechanically unlock the hatch even in the absence of electricity through a special cable located under the bottom panel.
The differences between the models often lie in the depth of the case and the maximum load. Narrow models are designed for small apartments, while full-size options allow you to wash up to 5-6 kg of dry linen. The control system can be either completely electronic with a display or combined, where the selection of programs is carried out by a rotary switch, and additional options are buttons.
- 🔹 Load: It varies from 4.5 to 6 kg depending on the specific modification (WAA, WAE, WAS).
- 🔹 Push: The maximum speed of rotation of the drum reaches 1000-1200 rpm, which provides low residual humidity.
- 🔹 Energy consumption class: A+ or A+ is a good indicator for the technology of the time.
⚠️ Note: When buying a used Max 5 series machine, be sure to check the condition of the rubber hatch cuff and the absence of a backlash drum. A worn cuff is a common problem of age models, leading to leaks.
Do not underestimate the importance of proper installation. Even the most perfect technique will vibrate and make noise if it is standing on an uneven floor. Adjustment of the legs is not just a recommendation, but a necessity for the safety of the bearing assembly.
Decoding error and malfunction codes
Electronics of washing machines Bosch It is equipped with a developed self-diagnostic system. When deviations from the normal operating algorithm are detected, the machine stops the cycle and signals an error. On models with a display, the code is displayed in an alphanumeric combination, for example E18 or F21. In models without a display, the malfunction is indicated by the blinking of certain LEDs or a combination of sound signals.
One of the most common problems is the error associated with water drain problems. The machine may hum trying to start the pump, but the water remains in the tank. Often the reason lies not in the breakdown of the pump, but in the banal clogging of the filter or pipes. Before calling the master, it is necessary to conduct an initial audit of the drain system. It is also common to have a water dialing error when the machine does not draw water in the allotted time.
Problems with the engine or the tachodilator are also fixed by the system. If the drum does not rotate or rotates with jerks, the electronics block further work to avoid fire of the windings. In this case, it is important to check the brushes of the engine - this is the consumablewhich is subject to scheduled replacement.
- 🔸
E18(or flashing plum indicator): A problem with water drainage. Check the filter, the hose and the pump. - 🔸
E09Engine error. Possible problems with brushes, tachodilator or control module. - 🔸
E11Engine symistor error. An electronic module diagnostic is required. - 🔸
F21: Engine error (long circuit). Often indicates wear of brushes or malfunction of the tachogenerator.
⚠️ Note: Resetting an error by turning the machine off the socket does not eliminate the cause of the breakdown. If the error is repeated after restarting, mechanical intervention or replacement of parts is required.
For accurate diagnosis, a multimeter vertebrae of elements is often required. For example, the resistance of the engine windings or the integrity of the TEG are checked in the resistance measurement mode (Oms). The absence of evidence indicates a break in the chain.
How to Reset the Error on Bosch Maxx 5?
To reset the error, try to turn off the machine, then press the "Plum" button (or a combination of buttons depending on the model) and turn the program selector to the "Off" position without releasing the button. Then turn the car on. Remember, however, that this is only a temporary solution.
Prevention and regular services
To make the washing machine Bosch Maxx 5 She has worked for many years and needs regular care. Preventive work takes a little time, but avoid serious breakdowns. First of all, attention should be paid to the drain pump filter, which is located in the lower right part of the body behind the decorative panel.
Clean the filter every 3-6 months, depending on the intensity of use and the degree of contamination of the linen. It accumulates coins, buttons, pile and threads that can block the impeller pump. Before unscrewing the plug, be sure to substitute a flat container for draining the remaining water, since it will flow out of the system by itself.
The second important element is the tray for detergents. It must be periodically extracted and washed under running water, removing the fossilized powder and mold. Old plaque can cause poor washing of chemistry and the appearance of an unpleasant smell. Also check the holes in the tray niche through which water is supplied.
☑️ Monthly maintenance of the washing machine
Do not forget about the external cleanliness. Wipe the body with a wet cloth, avoiding water on the control panel. The rubber hatch cuff after each washing is desirable to wipe with a dry napkin, removing moisture and small debris to prevent the development of fungus.
Replacement of consumables with their own hands
Technological skills Bosch It is convenient because many units are designed with maintenance in mind. Independent replacement of some parts is possible for a person with basic skills of working with the tool. The most frequently replaced elements include engine brushes, drain pump and hatch cuff.
The engine must be removed to replace the brushes. It is usually attached to the tank with two bolts from below. Removing the motor, you will see graphite brushes in plastic holders. If the length is less than 1 cm, replacement is required. It is important to wipe new brushes by running the car on a short cycle without laundry.
Replacing a drain pump also does not require complex equipment. After removing the bottom panel and disconnecting the pipes, the pump is easily removed from the seat. The main thing is to connect the wire chip correctly and make sure that the connections are tight after assembly. Use of original spare parts or quality analogues (for example, Askoll or Plaset) guarantees long service.
| Detail | Resource (exemplary) | Difficulty replacing | Signs of wear and tear |
|---|---|---|---|
| Engine brushes | 5-7 years | Medium | Sparking, loss of pressing power |
| Pump pump. | 3-5 years | Low. | Noise, hum, no water drains |
| Manhole cuff | 5-8 years | Medium | Cracks, leaks, black plaque |
| TAEN | 7-10 years | Low. | He doesn't heat the water, knocks out the machine. |
⚠️ Before starting any work on dismantling and replacing parts, be sure to disconnect the washing machine from the power grid! Working with electrical appliances under tension is deadly.
When assembling the machine, make sure that all the clamps are tightened, and the wires are not clamped by the body. Poor-quality assembly after repair is a frequent reason for repeated calls to the service.
Bearing and tank problems
One of the most serious problems that owners can face Bosch Maxx 5 After 7-10 years of operation, the bearing unit wears out. The symptom is the growing hum during spin, which resembles the sound of a plane taking off. If you do not react in time, the backlash of the drum will lead to the destruction of the osteum and the leakage of water to the engine.
In most models of this series, the tank is soldered at the factory, which formally requires its replacement entirely along with bearings. However, there are services and methods that allow you to saw-offpress new bearings and assemble the body back onto bolts and sealant. It is cheaper to buy a new tank, but requires a high qualification of the master.
Check the condition of the bearings can be manually. Open the hatch, press the top of the drum and spin it. If a crunch is heard, there is a jamming sensation or a rusty trace is visible on the cuff under the drum - bearings require replacement. Ignoring the problem can lead to a jamming of the engine.
To extend the life of bearings, try not to overload the machine with underwear over the norm and use special means to soften the water if you have hard tap water.
Replacing the tank in the assembly is a time-consuming process, requiring almost complete disassembly of the machine. It is necessary to remove the upper cover, control panel, counterweights, engine and shock absorbers. Therefore, the cost-effectiveness of such repairs is often questioned, especially for older models.
Frequently Asked Questions (FAQ)
Why does the Bosch Maxx 5 washing machine not open the hatch after washing?
Most often, the reason lies in the fact that the tank remained water, and the lock is not removed for safety reasons. Check if the water residue indicator is on. If there is no water, it is possible that the locking of the hatch (UBL) itself is faulty or the contacts are stuck. Try to turn the car off the socket for 15-20 minutes, then turn it on again. In emergency cases, use the emergency opening cable.
How to clean a car from scale without special means?
Citric acid can be used. Pour 100-150 grams of acid into the main powder compartment and start the wash cycle at a temperature of 60-90 degrees without laundry. However, this method should not be abused, since acid can damage rubber elements with frequent use. It is better to use specialized water softeners for each wash.
What does the flashing indicator "Key" on the panel mean?
This is an indicator of activated child protection function. While this symbol is burning or flashing, it is impossible to start or change the washing program. To disable the function, you usually need to press and hold the key button (or the button combination specified in the instruction) for 3-5 seconds before the confirmation sound signal appears.
Can I install a Bosch Maxx 5 washing machine on a wooden floor?
Installation is possible, but requires additional preparation. Wood flooring can resonate and increase vibration. It is recommended to use an anti-vibration mat under the car and make sure that the base of the floor is strong. If the floor bends, the machine will "jump" when pressed, which will lead to breakage of shock absorbers or tank.
Where to find the model number for ordering spare parts?
The full article (E-Nr) and the factory number (FD) are indicated on the information sticker. In Bosch machines, it is most often located on the inner end of the hatch, on a rubber cuff or under a removable lower panel. For the order of spare parts, it is the code that is required E-NrThe name Maxx 5 is not exactly suitable for the details due to the large number of modifications.
