No spark in the gas column is often so frivolous problem, what to fix it on their own, not having skills in repair of household appliances and gas equipment. Moreover, most gas water heaters have the same principle and to understand their work on the example of any particular model.

If the column for a long time not used, then the reason for the lack of a flame could be the accumulation of air in the pipeline. As a rule, short-term grazing (1-1,5 min.) solves this problem. If, before taking measures to repair the user tried several times to turn on the heater, during these attempts the air out himself.

If gas heater does not ignite, first check the batteries that run all electronics and piezo ignition. The easiest way is to buy new batteries and change them. In 90% of cases this gives the desired result. Another thing, if the speaker is powered by built-in generator. In this case, and, if new batteries did not help, check for spark at the time of switching of the column. It is possible, due to a malfunction of the piezoelectric element or to supply the spark cable is in the wrong place. Inspect the electrode and wire for external damage.

If external damage is observed, check their condition with a multimeter. Checking resistance on both ends of the wire, you can determine whether it. In the case of internal rupture of the meter should show infinite ohms. If the cable is working properly, the reason lies in the piezoelectric element or the power button. Use a multimeter to check the electrode contacts in the ignition. The presence of the voltage will indicate that all items are serviceable, except of the piezoelectric element. If you have confidence, you can replace it yourself with a screwdriver and soldering iron.

Before replacing the faulty components, don't forget to clean contacts of the electrode, power cable and button ignition (automatic control of the ignition). Rarely, but it happens that the voltage of the banal oxidation of contacts.

Gas water heaters latest models with the control electronics and power supply from integrated generator is more complex than the speakers on batteries and push button ignition. The complexity of their self-repair is the difficulty of soldering and inaccessibility of spare parts. If you have skills of soldering of electronic elements and a good soldering iron, you can take on the job. If not – better not risk it. Spare parts it is better to look at specialized workshops. In stores that sell gas and water heating equipment, they are almost not sold
