The electric ignition of a Bosch gas stove does not work

Signs of failure

Electric ignition of gas stoves can break suddenly: the switch turns, the gas goes out, but there is no spark. Failure of an additional function can occur for absolutely different reasons.

But first of all, it is worth determining that the ignition function of the gas stove is really out of order. This can be indicated by the following signs:

• The ignition function does not work when the control knob or burner button is pressed;
• automatic functions of the device operate in a continuous mode, a click-like sound is noted. At the same time there is no spark, the gas stove simply does not ignite;
• When releasing the knob or button, there is no shutdown of the system;
• The appliance works even without pressing the button;
• If a residual-current circuit breaker in the area of the fuse box breaks during switching on the device;
• The presence of a fault can be identified by the piezo- and ignition circuit, it may be closed.

Requirements for a stove with an electric ignition

Unlike a conventional gas stove, the device with an electric ignition must be connected to AC 220 volts. For this purpose, it has a three-core cable with a cross section of at least 1.5 mm, ending with a plug with grounding. Near the appliance, an earthing switch socket must be installed. On the input panel, be sure to install a standard circuit breaker. As an additional safety feature, a residual-current device can be installed that blocks the network in the event of leakage current.

Find the cause of the problem

If your gas stove burns badly or does not ignite the burner, you must first disconnect the equipment from the gas and electricity. Inspection and repair of the hob must only be carried out after the gas supply has been shut off.

Basic safety precautions should not be neglected here.

Whether or not you smell gas in the kitchen after burner fading. it does not matter, any manipulations on the servicing of gas equipment should be performed only with open windows and good natural ventilation of the room

Many modern gas stoves are equipped with electronics and automatic ignition systems that require electrical power. Often inexperienced home craftsmen forget about this feature of this appliance when working with a gas cooktop. The consequence is that methane vapors are ignited by sparks. Therefore, it is advisable to unplug not only the stove itself, but also all electrical appliances in the kitchen before beginning repairs.

Problems with gas stove burners are caused by:

• Improper operation of the solenoid valve and/or thermocouple;
• The gas will not be supplied to the consumer without such an agreement;
• Faulty ignition plugs;
• Long interruptions in the service of gas equipment.

Owners of private homes and apartments where there is a gas stove, must enter into a contract for regular inspection of the equipment in question with a specialized organization. Without such an agreement the gas will not be supplied to the consumer.

And gas workers should come at least once a year to check if the stove is working properly and if necessary to repair it as soon as possible. All other calls are charged separately.

If the problems with the stove occurred in the period between routine inspections, you will either need to call a master once again, or repair yourself

In this case, if you self-repair burners and other devices hob will be damaged, then without a gasman faulty device will not include. Even if the stove is more or less workable, then the annual check by a specialist from the gas company will identify the defect and immediately cut off the gas until the defects are corrected. And this is inevitable extra expenses. Plus, you can still get a fine.

To take up for repair of the gas stove with your own hands is recommended only if you are sure that you will do everything correctly. There are no particular difficulties in this work, but it is possible to break something through carelessness or ignorance.

• The color of the flame is not as blue as it should be. there is not enough oxygen or too much gas at the nozzle.
• The burner does not ignite. soot clogged spray holes or a faulty thermocouple or candle.
• The fire goes out. the gas supply is cut off due to faulty gas control or problems with the gas pipe.

You can clean or replace a burner on the gas stove yourself. But if the problem area is the meter, the tube with gas (cylinder) or an external gas sensor, it is better to refrain from self-abuse.

In such a situation you can call for help from the gas supply company that is responsible for the condition of the internal combustion chamber and the gas pressure system.

The ignition switch does not turn off

In the case of long-term operation, activation occurs through contamination of the pushbuttons by grease or food. Food and water get on the moving parts. The return spring is unable to overcome the resistance and push the mechanism back in, so the ignition continues to click after the burner is turned on. In this case, you should perform maintenance on the rotary knob and the pushbutton assembly. Remove the plastic handles (turntables). Moisten a cotton swab with ethanol. In the holes under the handles, carefully wipe each button. Grease can be removed with a dry cloth. Soak the handles in a soapy solution and rinse under running water.

Can the ignition switch be repaired by yourself??

Some faults can be solved by the user. However, you should understand that all work must be performed in accordance with the manufacturer’s recommendations. If the product is still under warranty, you should not do anything yourself, because the service company employees are obliged to fix all the problems according to their obligations. If any internal elements do not work, it is worth contacting professionals who will be able to say whether it is necessary to buy new parts, or you can repair the native components and bring the electric igniter back to life.

To diagnose faults, you need to light the burner and observe how evenly the flame will burn, whether the fire is distributed over its entire surface. Normally the fire should turn purple, depending on the intensity of combustion. However, if the flame turns orange or yellow, you can immediately tell that this phenomenon is abnormal and that the device is not working properly. If the flame only appears on one side, it could indicate that the flame spreader is not working properly or that the hob is standing on an uneven surface, which leads to operating problems. As a rule, in this position, the ignition switch on the gas stove does not work. You can either deal with cleaning the nozzle or install a new model of diffuser. When the mixture is not evenly distributed, the ignition will not work. This is already the system of the device itself.

All components are connected in parallel. The power is supplied by the unit responsible for ignition. However, the ignition occurs through the use of various buttons or levers. If the spark does not appear and the gas is open, it is worth trying to use the second button without releasing the first. If nothing happens, then the breakdown is 100% real, and it is better to contact a specialist to fix such problems.

If for a long time the technique beeps or cracks, it means that the problem is in the clamping of contacts. Similar sounds can be observed when the electric ignition on the gas stove “Gefest” does not work. As a rule, this occurs due to grease, products that contribute to the oxidation of elements. In order to avoid this situation, you must periodically clean the hob and allow the parts to dry thoroughly. In this way you can take care of prolonging the life of the device or eliminate the problem. It is not advisable to forget about your own safety. Since the stove works under 220W voltage, you must first be sure to disconnect it from the mains, as well as shut off the gas supply.

What other malfunctions can occur?

Quite a common problem is considered disconnection of the gas burner during operation. If this is the case, you should first observe how well the fuel burns. You can either clean the nozzle or adjust the gas supply. If such actions were useless, it is recommended to contact the technician to determine the cause. Most likely, you will have to buy a new thermocouple, which can not be replaced by yourself without some knowledge.

BOSCH STOVE CLICKS BUT WON’T �� LITE—SUPER EASY FIX

Often the burner has a smaller flame. If no adjustment has been made up to this point, it is likely that the problem is in the nozzle, which should distribute the gas and supply it for combustion. Most often it is clogged with oil or grease, so all you need to do is just clean the part. If the gas stove. “Ariston”, the ignition does not work on models of this brand is often for this reason.

Principle of electric ignition

In contrast to the majority of household appliances repair of gas stoves with electric ignition forces you to master the technique of replacing resistors. Frequent, continuous process. Newcomers challenging the feasibility of the event cause general resentment from forum members. Call the layman offensive words, condescendingly explain, inside the high-voltage unit:

The electrical scheme is poured with compound on purpose, a sucker will not get inside. You’ll unscrew them, saving yourself 30 bucks. Self-taught ignores the thoughts of the manufacturer on the protection of products against unauthorized access.

Gas stove electrical ignition unit optionally contains control elements. thyristors, triacs. It takes a long time to explain the exact principle of operation of the components of the ignition switch. Worth noting: the behavior of the semiconductor products resembles a key (faucet. more usual thinking for plumbers). Semiconductor electronic elements are used to drive a power line by means of a voltage amplitude of 5-12 volts.

The analogy of a water valve is complete. Man applies a symbolic force to open the tap, releasing the pump’s inconsequential power. The minuscule voltage of the control electrode reaches the operating point, the thyristor opens, triggering the electric ignition circuit. Two positions: open, closed. Pure digital microelectronics. Any processor is formed by semiconductor keys minuscule, indistinguishable to the human eye. PCs are considered the logical evolutionary extension of electronic circuits.

A high-voltage transformer raises the voltage (units of kilo volts) of the output winding, the burner arcs light up. Gas is fed by the same name knob, triggering the ignition circuit. There are other models of devices. The spark ignites the gas:

• by pressing a button, the cook charges a capacitor with the rectified voltage;
• capacity begins to accumulate electrons;
• the voltage level of the control thyristor rises when it reaches the threshold value, the capacitor discharges, heating the transformer primary
• The output of the ignition circuit generates a voltage that triggers the arrester;
• The spark ignites the gas.

The principle of electric ignition is based on charging a capacitor through a rectifying diode to a certain level. Specific implementations of the circuit varies. be ashamed to read an electrical engineering textbook: to repair the ignition of the gas stove with his own hands is as easy as pie. Know a few rules, know how to solder.

Electric ignition provides the ability to ignite the stove safely. It reduces the possibility of getting burned to a minimum, because with piezo ignition it is not necessary to use lighters or matches. There is also no contact with the flame. With electric ignition, gas is ignited by actuation of the piezo element on the gas device. The piezo element produces a spark, which is followed by automatic ignition without the use of other devices. Repair of gas stoves with an electric ignition can be done with the help of a master and with your own hand: it all depends on the type of failure and knowledge of the work of construction.
