What is it and how does it work?

Let’s talk about the pilot light, a small flame that plays a big role in gas water heaters. It’s essentially your heater’s heartbeat, working tirelessly to keep your water warm and ready.

A thermocouple sends electric signals powered by this tiny flame to the gas valve, ensuring it stays open so that the main burner can ignite when needed – giving us those lovely hot showers on cold mornings.

We understand having no hot water is frustrating, so knowing how your system works helps fix issues faster. If the pilot light goes out or doesn’t function correctly, it could mean cold showers until we sort it out! It relies on a consistent flow of gas to maintain its flame; any interruption here and you’re looking at troubleshooting gas water heater pilot light issues.

Keeping an eye on this crucial component is key for uninterrupted service from your heating element, making regular checks part of essential water heater maintenance.

How to visually inspect it

To visually inspect the pilot light, follow these simple steps:

  1. Turn off the gas supply to the water heater.
  2. Remove the access panel to locate the pilot light and burner assembly.
  3. Look for a small, blue flame at the end of the gas line near the burner.
  4. Check for any signs of soot, dirt, or rust around the pilot light and thermocouple.
  5. Ensure that no obstructions or debris are blocking the flow of gas to the pilot light.
  6. Examine the colour and size of the pilot flame – it should be a steady blue flame with a defined shape and size.

Common Pilot Light Problems and Troubleshooting Tips

If you’re experiencing issues with your gas water heater pilot light, there are a few common problems to look out for. From the pilot light constantly going out to it not staying lit, we’ve got some troubleshooting tips to help you get your hot water flowing again.

The pilot light constantly goes out

If your pilot light is constantly going out, it could be due to a dirty or damaged thermocouple. Check for soot, dust, or corrosion around the thermocouple and ensure it’s properly positioned in the flame.

If cleaning doesn’t work, you may need to replace the thermocouple. Another possible cause could be a faulty gas valve or draft issues within your home. To troubleshoot this problem, inspect for any draughts near the water heater and consider installing a wind guard if necessary.

When troubleshooting pilot light issues with your gas water heater, always prioritise safety first. Turn off the gas supply before inspecting or attempting any fixes and do not hesitate to seek professional help if needed.

The pilot won’t light

If your pilot light is constantly going out, it could be due to various reasons like a dirty or clogged pilot assembly, insufficient gas supply, or a faulty thermocouple. When the pilot won’t light at all, first ensure that the gas supply valve is fully open and check for any blockages in the pilot tube.

Next, try lighting the pilot according to your manufacturer’s instructions; if it still won’t light, there may be an issue with the thermocouple needing replacement. Moreover, make sure no draughts or strong winds are affecting the pilot light’s ability to stay lit.

Remember to always prioritise safety when dealing with gas appliances – if you’re unsure about troubleshooting such issues on your own, don’t hesitate to seek professional help for further assistance.

The pilot won’t stay lit

If your pilot light won’t stay lit, first ensure that the thermocouple is positioned correctly in the flame. Clean the thermocouple and make sure it’s not covered in soot or debris.

Next, adjust the position of the thermocouple so that it sits directly in the path of the pilot light flame. If this doesn’t solve the issue, check for any drafts near the water heater that may be blowing out the pilot light.

Pilot flame is too large or too small

If the pilot flame on your gas water heater appears to be too large or too small, it could indicate a problem with the gas pressure or the air mixture. First, check for any obstructions in the pilot tube that may be affecting the flow of gas.

Use a small brush or compressed air to clear away any debris. Next, if your unit has an adjustable air shutter, use it to regulate the amount of oxygen mixing with the gas. This can help achieve a more balanced and steady pilot flame.

Should you notice that adjusting these factors doesn’t resolve the issue, you may need to call a professional technician who can accurately diagnose and address any underlying problems with precision equipment and expertise in line with guidelines for ensuring safety at all times.
