To reach the main problem there are several pilot light diagnosing methods that you can follow. Hence, it is important to check why your pilot light of the water heater is not turning on or why it goes off.

Effective Diagnosing Tips to Light The Pilot Light On Water Heater
1. Water Heater Pilot Lights On Tankless Coils And Indirect Water Heater
Tankless coils and an indirect water heater work almost the same way. Their pilot light ignition-off problems come mainly from heat exchangers and boiler issues. This is much trickier to troubleshoot in DIY because you need to open the insides and inspect the activity of the heat exchanger inside.
2. Demand Water Heater Diagnose & Turn On Water Heater Pilot Light
For a demand-based water heater that switches itself on only during demand unlike the conventional type, the pilot light problem is potentially caused by a parallel sequence installation. You need to check your electric connection setup for the demand water heater to see if the power is not blocked up from there affecting your water heater pilot. This is mostly where the conflict on-demand water heaters lie and can immediately snuff out problems.
3. Water Heater Pilot Light Troubleshooting for Conventional Storage Water Heaters
Conventional storage water heaters are often powered by electricity, natural gas, oil, and propane. Their maintenance costs are more than the other water heaters because it will require that the heating mechanism be turned on forever even when you have no faucets open for a particular time period.
For this type, you will focus your attention on checking out the compression of the gas regulator valve or for potential blockages from within the system. Once you try flickering the gas regulator valve, you will have to monitor for the next few minutes up to intervals leading to an hour and see if your reset of the valve has already resolved the problem.
4. Heat Pump Water Heater Pilot Light Not Turning On
The heat pump water heater is considered to be some form of the reverse fridge because it operates under the same principle but applies it to heating instead of cooling. It is isolated and usually, it cools the area where it is placed. The furnace is a perfect spot for installing this type because it harnesses the air space filled with heat to generate heat for your water.
Pilot light malfunctions for this type of water heater happen when you do not install the water heater in the appropriate temperature range of 4°F to 90°F. Cold spaces also tend to bungle up their function so it’s often advised not to put this installation on cold areas of your home or office.
5. Solar Water Heater Pilot Light Problem
Some people are now going the renewable energy route and using solar power to help them have an optimized heating system. Typically, problems for this type involve a solar collector issue.
If your solar collector is working properly and you still find that the pilot light is not working as it should, you can also check out if the size of the solar water heater is sufficient for your home needs or if the thermosiphon, pumps, or connection to solar storage are not functioning properly.
