The mixer is one of the most convenient household appliances used to mix ingredients at high speeds. The modern device is characterized by increased resistance to stress and advanced features. If for some reason it does not turn on, the whisk does not rotate or the speeds do not switch, it is necessary to disassemble the device and determine the cause of the breakdown.
Mixer Types
There are 2 types of mixers: stationary and submersible. Stationary models are automated kitchen systems that perform work in a special bowl installed under the whisks. Beating is done without manual control of a person. It is enough to set the settings and enable the necessary mode.
Submersible models are stand-alone appliances with removable nozzles that can be used to mix and whisk ingredients in any dish. Compactness makes them practical for operation. At the same time, submersible models must be kept in hand constantly in order to control the quality of mixing.
Design features of a stationary mixer
Stationary models are more complicated in technical parameters than submersible ones. But you can disassemble and repair any type of device. The design of the desktop model consists of the following elements:
- Gear wheel over gear shaft.
- Belt.
- Gear wheel drive gear.
- Gear mechanism.
- Removable whisk nozzle.
- Console lock buttons.
- Mode deactivation buttons.
- Mode switch.
Stationary are equipped with a 700 W engine. Their activation is performed by a handle equipped with a speed switch. It starts the motor shaft, which is equipped with a mechanism with gears rotating in the opposite direction and a ventilation system that controls overheating. Gears are responsible for the rotation of the corollas, which are inserted under them. Inside is a gearbox that rotates the beaters. Above it is a belt that rotates the wheel. The nozzle is attached to the top of the engine. All internal systems and structures are damaged, therefore, to clarify the causes of failure, it is necessary to disassemble both the mixer nozzle and the body itself, and then assess the likely damage.
Submersible Mixer Device
Many prefer to repair small household appliances on their own. The internal design of the submersible mixer is quite simple, but there are some nuances and tricks that you should know about in order to perform the job correctly. The device consists of several interconnected structures:
- Engine.
- Gear shift mechanism.
- Gear.
- Removable whisk nozzles.
- The fan.
- Ventilation holes.
- The straps of the cord.
All these structural elements are interconnected, and failure of one part can lead to complete deactivation of the device. Mixer repair can be done at home, most importantly, carefully disassemble the case without damaging the fasteners.
How to disassemble the mixer
The most common reason for disassembling the device is that the mixer does not turn on. Modern mixers have a die-cast housing. This allows you to make fasteners hidden. Most often they are at the bottom of the recess in the housing.
Sometimes they are covered with plastic plugs and in order to remove them, you need to gently pry the linings.Also, fasteners can be hidden under the sliding legs or self-adhesive labels. It is necessary to carefully examine the surface for the presence of recesses. In this way, gain access to the mount of the mixer, and then dismantle them.
Screws or self-tapping screws are usually used to connect the elements. Sometimes plastic latches are used, which must be handled very carefully. After the case is open, you need to take a photo of the contents, so that after the repair work is done, put everything in its place, otherwise the device simply will not turn on and all the manipulations performed will be in vain.
You can repair yourself any model of Philips (Philips), Bosch (Bosch), Kenwood (Kenwood) and other manufacturers mixers. If after opening the breakdown was not found or it is impossible to fix them manually, contact the service center for repairing small household appliances.
Common failures and their elimination
Mixers are characterized by failures associated with the electronics and the internal design of the device. The most common problem is lack of contact, damage to power in the cord, damage to the gearbox or motor parts. Consider the most common repair cases and instructions on how to fix them:
- Not all speeds work - problems with the switch. If the switch is autonomous, then it will be possible to repair it only in the service center. If it is mechanical, then you can visually independently evaluate the health of the contacts. It is necessary to check the position of the wires, to clean the contacts from dust and dirt. Blown wire must be replaced or contact restored.
- Noise during operation - lubricate the gearbox. You need to disassemble the case and inspect the plastic gear. She disassembled by unscrewing the screws. If during opening it is found that the white grease has shifted, you need to carefully adjust it with a screwdriver along the bearings of the gearbox. When there is no lubricant at all, you need to purchase and replace it. If the cause is not eliminated, then the noise may be due to wear of the bearings of the motor.
- No power - check the gearbox, as well as the condition of the fuse, the plug is correctly connected to the network, and there is no break in the cord. If there is no contact, replace it. Check the gearbox for proper operation. If the gear does not rotate, then it is easier to replace the gearbox with a new one.
- Vibration during operation - motor belt damaged. If the drive belt is stretched or the teeth are damaged, then it can create excess noise from the rotation of the electric motor. In this case, the gearbox will be static, and the corollas will not stop rotating. It is necessary to remove the cover and check the belt tension, moving it to the largest gear, to assess the external condition and the absence of visible damage. Replace belt if necessary and grease parts.
- The corolla does not rotate - the planetary mechanism is damaged. If the whisk does not rotate during operation, and when turned on, an uncharacteristic sound appears, check the planetary gear, the rotation of the gears and the integrity of the electric motor belt.
If you can’t install and repair the malfunction yourself, contact a service center for repairing small household appliances. Some problems are not repairable and cheaper to buy a new model of better quality. Over time, equipment becomes malfunctioning, especially after a certain number of cycles.
The silumin part cracked into two parts for attaching the corollas after they were inserted into the STERLINGG 7 speed mixer model ST-450. Help find this item. thank
