Gas geyser not turning on or not working: what to check

1. Is there gas?

Light a stove burner. If it will not light or burns very weakly, the problem is supply or pressure, not the geyser. Wait for supply or see our low pressure guide.

2. Are the valves open?

Check the gas valve on the pipe to the geyser is fully open. After plumbing work or a long holiday, someone may have closed it.

3. Does the igniter spark?

Press the piezo button and look or listen for a click and spark at the pilot. No spark means a faulty igniter or wire; you can still light with a long lighter while you get it fixed.

4. Does the pilot light?

Hold the knob on Pilot and spark. If gas is present but the pilot will not catch, air may be in the line after a long cut: hold the knob longer. If it still will not light, the pilot jet may be blocked.

5. Does it stay lit?

If the pilot lights but goes out when you release the knob after 30 to 60 seconds, the thermocouple is the usual culprit. If it stays lit but the main burner never fires, suspect the thermostat.

Not working after every load shedding?

If the geyser works fine once relit but is off every time gas returns, nothing is broken: the pilot simply went out with the gas. Automatic ignition fixes that pattern.
