    Hello!

    I am the owner of the TERMET G19-02 Electronic gas water heater.
    Some time ago, there were problems with the main burner lighting. The ignition pilot works, of course, it is cleaned. Replacing the battery did not solve the problem.
    To start this stove, you need to turn off the warm water and lightly tap (set in vibrations) the tube that reaches the stove.
    I measured the coil voltages.
    Coil (orange) - 1.1V
    Coil (green) - if it does not fire, 0.01V, after switching off the stove and tapping 1.1V.

    Here I found the service manual http://www.tukado.pl/file/electronic-aquapower.pdf
    Will it be the fault of the coil or is the problem deeper because it does not get voltage?

    What tube are you writing about?
    Check that the detection electrode is clean, including the entire cable to the controller.
    If the electrode does not confirm the presence of a flame on the remote control, the controller will not allow you to turn on the main burner.

    I have a Demrad water heater in which, despite the battery being replaced, the magneto does not work. I observed an interesting thing, namely on previous batteries the sparker gave a spark despite the twisted water. What could be the reason?

    If the spark gap gives the spark all the time when the valve is closed, the needle in the water unit acting on the microswitch or the microswitch itself is damaged.
    Depending on how it is included in the control system, in extreme cases it may even be a damaged module.
    If after replacing the battery the stove does not work, I would start by checking the correctness of battery insertion.

    I apologize for the late reply, but I was still waiting for the battery to be replaced because it was getting worse.
    I meant a tube that brings water to the junkers. It is next to the spark generator. TERMET G19-02 Gas Water Heater: Main Burner Ignition Issues, Coil Voltages & Troubleshooting
    The metering electrode has been cleaned.

    The coil is not guilty of not getting voltage. Because if it doesn't get voltage, it won't open the valve.
    Check for loose cable or temperature sensors.
    one is attached to the heater (heat exchanger) and the other is the chimney draft sensor or rather its lack.
    If you have a meter, check if one of these sensors is not open when the stove does not want to ignite the main burner.

    I could not find out how these sensors work (resistance will increase?). After disconnecting the sensors, it does not fire, and after bridging there are sometimes problems with firing. Of course, I removed bridging.
    I will add that I once had a similar problem as @R ... : the magneto worked all the time, even after switching the microswitch. Only pulling out the battery worked for a long time.

    Temperature sensors are contact.
    After exceeding the appropriate temperature, the contact inside them opens and breaks the circuit.
    If the bridging did not permanently fix the problem, either the connector on the module or the problem is inside the module itself.

    Module or spark generator?

    The only thing that puzzles me is the fact that tapping on the stove goes out solves the problem.

    The module is not just a spark generator.
    Inside is the electronics of the flame presence sensor connected to a monitoring electrode, systems controlling solenoid valves and controlling the degree of battery wear.
    If as you write when you tap or right into the vibrations, the problem disappears, it means that somewhere there is something loose, no contact.
    Unless the information you provided at the very beginning is incorrect and the problem is mechanical in nature associated with the gas unit.

    I meant that under this name "spark generator" they sell this module. I understand why this is an electronic problem. I repeated the measurements, in fact there is no voltage on the coil. I will probably make one more connection with the dosing electrode again, because the cable was short and the service technician has blocked it.

    It would be most convenient to replace the module for testing and then we would have confidence in what is damaged.

    This will be the best idea, because after making a solid connection with the electrode, there are still problems. I'll let you know.

    I have a similar problem with ignition (new battery), after unscrewing the water, the spark is a flame, mainly burners trying to catch fire - flame close. This condition lasts for a few minutes and the main burner fires or the wait is longer.
    I would like to add that blowing connotations favors faster ignition of the head. burners.
    I am asking for a hint where to look for the fault?
    best regards

Topic summary

The discussion revolves around ignition issues with the TERMET G19-02 gas water heater. The owner reports that the main burner fails to ignite despite a functioning pilot light and a battery replacement. Tapping the tube connected to the heater temporarily resolves the issue, suggesting a possible loose connection. Responses highlight the importance of checking the detection electrode, temperature sensors, and the control module for faults. The coil voltages measured indicate potential issues with the electrical connections or the module itself. Suggestions include testing or replacing the module to diagnose the problem accurately.
