Electric, induction and gas hobs are used for cooking. Each of them has its own advantages and disadvantages, and there are also a number of malfunctions that can be eliminated independently if they occur. Do-it-yourself repair of the hob can be done subject to certain recommendations and with the necessary tools.

Electric hob repair

In some cases, you can repair your Bosch hob yourself.

If, when the power is connected, one of the burners does not work or the entire device does not work:

1. We check the voltage in the outlet with a multimeter. If it is, then the problem lies with the hob itself. You can check with an indicator, but it only indicates the presence of voltage. A significant change in the current indicators can lead to the operation of protective mechanisms.
2. We check the condition of the electrical cord and plug. If there is mechanical damage, it will be enough to replace the cord or plug. You can also check the supplied current on the panel itself, since mechanical damage is not always the cause of the cord and plug malfunction.
3. If the cord with a plug, the socket is in good condition, we dismantle the hob.

If you repair a glass-ceramic hob with your own hands, you should know that the malfunctioning of some structural elements can only be detected with a multimeter, by taking measurements in individual sections of the circuit. When considering a Bosh hob, you should pay attention to the following elements:

1. Thermal fuse.
2. Transformer.

In the absence of resistance or at low rates, these elements should be replaced.

Frequent problems with electric hobs

Another common problem is a broken wire in the hob connection block. Under certain circumstances, they can burn out or, due to poor installation, there may be poor contact. Checking such a malfunction can be quite simple.

Let's highlight a few more problems that lead to improper operation of the hob:

1. Some models have fuses that can blow out due to high voltage surges. Their cost is low, the replacement procedure is quite simple. In order to protect expensive equipment from such situations, you should install a surge protection device. If the fuses constantly fail, you should check the operating features of the equipment itself, since the problem may not be in the indicators of the supplied voltage.

2. The burner may not work due to the fact that the contact on the heating element has disappeared. If the wiring is unsoldered, you can resume work, for which you need to have a soldering iron and be able to use it. The problem may be associated with the power supply, which also often loses contact.

   

3. If the sensor does not work, you can rarely solve the problem yourself. First, you need to ring the sensor, check if voltage is supplied to it. As a rule, sensor failure rarely occurs due to contact loss. Often it is necessary to repair the touch panel in services, in some cases only a complete replacement is possible. An example of improper use of the hob is the use of a saline solution for cleaning, which leads to burnout of the control unit.
4. If the hotplate does not heat up completely or overheats, which can lead to a fire hazard, there is a high probability of failure of the thermostat. It is this structural element that controls the temperature of the heated surface. You can replace the thermostat yourself, for which you need to disassemble the hob. Depending on the model of the hob, the thermostat can be soldered to the microcircuit or connected via a special plug.
5. The appearance of a crack or other defect on a non-glass ceramic surface is a rare occurrence, but it still occurs. Often the reason for the appearance of defects on such a surface is an admitted defect in production, as well as improper operation. It will not be possible to carry out repairs on your own, if not a warranty case, then the repair work will be expensive.

The design of electric hobs is quite complex, but many of its elements are highly reliable.

Induction hobs

The principle of operation of an induction hob is to directly heat the contents of the cookware, and not the surface of the stove or the cookware itself. Due to the fact that the hob remains constantly cold, such kitchen appliances are very popular.

There are several problems in which you can repair an induction hob yourself:

1. If the hob does not turn on or does not turn off immediately, do not panic. Modern models from the manufacturer in question are able to determine the type of cookware, its absence on the hob. Therefore, if the cookware is not suitable for induction heating or if it is not installed, then a protective mechanism is activated. Do not forget that induction cookers do not heat the hob itself.
2. If the heat is weak, then initially you should check the type of dishes used, whether it fits the recommendations.
3. Repair of induction hobs, as in the previous case, you need to start by checking the circuit for the presence or absence of contact. Fuses often fail, as there are often power surges in the network. In this case, simply change the fuse.

The rest of the repair of induction hobs is similar to the repair of electrical panels.

Required tools

To repair the electric and induction hob, you need to have the following tools:

1. Set of screwdrivers. In order to carry out many dismantling work, you need to have several different screwdrivers, which may differ in size and type of tip. In addition to ordinary screwdrivers, you should pay attention to the need for an indicator that detects the presence of voltage.
2. The mounting knife is often used when carrying out electrical work. As a rule, it is necessary for changing the length, stripping wire strands and other similar work.
3. Pliers are often used during assembly work. However, they often have a sharp part that can be used for cutting the veins.
4. It is often necessary to have wire cutters.

In addition, a multimeter may be needed to determine the voltage value. It determines various parameters of the supplied current. A soldering iron may be needed when carrying out repair work.
