Modern coffee grinders make it possible to make a coffee drink from real coffee beans at home. It should be borne in mind that these devices are intended only for grinding grains, if sugar and another component get into them, this can lead to failure of the device. To quickly bring the product in order, it is worth considering how to repair the coffee grinder at home with your own hands.
Using a coffee grinder
How to disassemble
Coffee grinder devices have a simple disassembly scheme that everyone can handle. The main thing is to study the sequence of the algorithm.
Coffee grinder model
All coffee grinders come in two types:
- with a knife device;
- millstones.
Models with a millstone device have a separate mechanism for disassembling the grinding mechanism. In addition, each model may have a different parsing process. But they have common features:
- it is worth paying attention to the fact that, for devices, conical knives are attached to the drive shaft with 3-4 bolts. They can be easily unscrewed with a screwdriver;
- when reassembling, it is important to ensure that the bolt heads fit exactly into the seats;
- If the bolts are not fully tightened, it may subsequently lead to failure of the device. Also, small metal particles will be constantly detected in the grinding, this may be due to the fact that the protruding parts of the fasteners will be in the area of movement of the grinding device;
- disassembling the case of coffee grinders is quite simple. To do this, several screws are unscrewed on the bottom plane, at the bottom of the device. Access to the mounting components may be open or the legs of the device may block it;
- a separate group of coffee grinders may have latches. To do this, use special probes or screwdrivers with which you can bend the latches.
Disassembled coffee grinder
An important part of the device is the engine. In order to dismantle and inspect this element, it is recommended to carry out the removal of knives. They can be removed using several methods:
- when the knife moves clockwise, the left thread is usually applied on the surface of the joint. To remove the screwdriver is placed in a special slot and rotates clockwise;
- when the knife moves counterclockwise, the right thread is applied to the joint. Accordingly, the probe screwdriver is also placed in the slot and rotates counterclockwise.
Engine and knife
Over a period of time, the fastener is clogged with particles from grinding. Also, oxides can have a negative effect on it. In order to remove all this, it is worth using special lubricants, also these tools can greatly facilitate the process of unscrewing the knife blocks.
If the clamping nut has a tapered thread and is made of bronze metal, then it is worth warming up the area with the connection a little. You can use a soldering iron for heating.
The subsequent process may depend on the model of the coffee grinder. In any case, the analysis of the device must be careful, accurate, during it it is necessary to monitor the stops, all elements must be correctly removed from the grooves.
After the knives are removed, you will need to perform only a few actions:
- the fixing nut is unscrewed from the plastic base. It provides fastening of a glass for grinding;
- when loosening the fastener, it is worthwhile to monitor the laying of the felt base. It must never be lost;
- then the axis washer is removed, which is made of a metal base;
- then the lock plate is removed. To do this, it is gently pushed down and out of the area with restrictive grooves.
Typically, for most coffee grinder models, the parsing process ends with the removal of antisplash washers and the dismantling of the power wire, switch. Often in the process of disassembling the device, it can be revealed that the failure occurred precisely because of the washer, for example, it burst or completely collapsed.
It is not difficult to repair the coffee grinder, the main thing is to disassemble the device correctly. During the analysis, the sequence must be followed, which will also need to be observed in the process of collecting the device back.
If during the analysis it is revealed that some element has broken or collapsed, then it is better to find out the details of the components for the model of a coffee grinder, this can be found on the Internet or in the instructions. Then it will be possible to go to the store or to the market to purchase the item exactly by number and series.
Types of malfunctions and their elimination
In order for the troubleshooting to be correct, it is necessary to consider the nuances of the repair. Damage may vary in degree of difficulty. Some of them can be eliminated on their own, but the repair of others may require the help of professionals.
To repair the engine or to establish its performance, you must have a multimeter. In addition, you need to have some abilities and knowledge to use the device.
At home, you can repair light damage, which can be eliminated in the absence of skills.
Power cable failure and lockout failure
Damage to the power cable can be seen visually without special diagnostics. If the bend area is located near the body, then you can detect a breakdown quite simply - just move the wire. If the device works, turns on, it means that it will be necessary to replace the cable.
Blocking failure may occur due to clogging of the mechanism. It is located on the line area of the lid groove. Also, this failure can occur due to the lack of pressure on the inner plate. Blocking can be easily done:
- for repair, you need a thin screwdriver, with which you click on the protruding element;
- if the coffee grinder is triggered when pressed, it is necessary to disassemble it;
- then you need to fix all the problems.
The device does not start
A household coffee grinder may not start due to several reasons:
- cable break inside the device. To fix it, you will need to have skills in working with a soldering iron;
- perhaps a contact has come off inside, which can be soldered into place with a soldering iron;
- if the appliance does not pray, this may occur due to a complete engine failure.
Internal cables and contacts
If there is a breakdown of the engine, then repair will require the availability of knowledge and experience. In this case, its repair will be ineffective, it can cost a good amount. This will require rewinding or the acquisition of a new engine. In these situations, it is better to buy a new coffee grinder.
Uneven movement of the knife, there is a sharp decrease in speed with an increase in grinding
The main reason for the appearance of this breakdown is a partial upset of the motor or the burnout of one of the windings. This also negatively affects the power of the device.
Anchor or engine
Repair can cause a lot of difficulties. It is advisable to take the device to a workshop for professional diagnosis.After it, the specialist determines the repair method - rewind or complete replacement.
The smell of burning appears during operation.
The main cause of this malfunction is the contamination or oxidation of the bearings and slide bushings. Additionally, the device reduces speed. This problem is often seen with Bosch 6000 Series coffee grinders.
Appliance cleaning
To troubleshoot the following steps are required:
- obligatory analysis of the device;
- checks the ease of sliding of all blocks;
- bearings are lubricated if necessary.
If this problem is observed with Bosch 6000 series coffee grinders, then the repair is performed as follows:
- remove the sliding sleeve from the top of the shaft;
- then the shaft is processed using an alcohol solution;
- in the presence of a corrosive lesion, its removal by special means will be required.
Everything is done using improvised tools.
Corrosion can be removed with an emery sandpaper. When cleaning, care must be taken not to damage important parts.
Safety rules for self-repair of the coffee grinder
Regardless of which model of the coffee grinder will be repaired - grain, millstone, during the repair it is required to observe important rules and recommendations during the repair. They will help to do everything safely without harm to health.
Detailing coffee grinder
Important safety rules include the following:
- work is recommended to be carried out in special gloves, they will protect from electric shock;
- in addition, you need to use special tools - a flat or figured screwdriver, pliers, electrical tape, pliers, a soldering iron and other necessary devices;
- during repair, the device should be disconnected from the mains;
- if there is damage or exposure of the cord, then do not touch it with bare hands, it is necessary to wear rubber gloves;
- splashed water should not get on the disassembled device, they can cause a short circuit;
- For replacement, use a part that exactly matches the model of the device. You can not use completely different components, they can quickly disable the coffee grinder;
