Since now we know that the problem lies with the ignition component of the water heater, what can be done to eliminate the error code?
We will discuss the different issues causing this error code with the solutions for them in this section.
Fix 1: Check the gas supply
The water heater utilizes gas as fuel to start up the ignition. If the gas supply is not sufficient or has completely run out, the heater will not initiate the ignition process.
There is a gas tank that has a regular supply of gas to the heater.
You will need to take a look at the tank and make sure that it has enough gas available for the heating to start.
The valves that need to be turned on for the gas supply to reach the heater can sometimes be absent-mindedly switched off due to negligence on your part. Make sure that it is not the case and that the valves are turned on.
Fix 2: The gas pressure and volume should be checked
Having a supply of gas is not an isolated requirement for the ignition. There are requirements about the correct pressure and volume of the gas that is present in the tank.
Unfortunately, if you are not a professional, there is a slim chance of you having any knowledge about this.
You will need external help with this issue.
Fix 3: Check if any of the valves have short-circuited
If the gas valves are turned on, they can still be the epicenter of trouble with the ignition. This can happen when the valves have short-circuited.
Everything might seem fine on the inside and when you take a closer look, you might notice a smoky smell or burned components.
Sometimes, only a technician can tell that the short-circuit has actually been in the picture as it is not visible at all.
Fix 4: The igniter might be broken
The igniter needs gas for the fuel but the function of ignition will still be carried out by the igniter.
The igniter might be broken or short as well.
You can take a look to see if there is any abnormal stuff that you can notice about the igniter. However, this is also a problem that can be only easily identified with the help of a technician.
Fix 5: Check the wiring
The wiring is an important component of any electrical appliance. If there are any wires that are bent or broken, it is a huge reason to worry.
Not only will your appliance not function correctly but you are also looking forward to safety and fire hazards in the near future.
Replace any wires that you notice are broken. Apply a cable protector for the new wires to prevent this issue in the future.
Fix 6: Contact a technician
The solutions that we have mentioned above are technical and while sometimes you might see the issue with the naked eye, most of the time you will need to get in touch with a technician to find out the issue for you.
They have a professional eye and professional tools for solving the problems with the appliance. They might immediately see the issue that you might not even notice with a watchful eye.
If the appliance is under warranty, absolutely call the support to help you with the issue. If the issue runs deep, you might be entitled to a replacement free of cost.
In either case, you will get the issue solved for little or no money.
We have suggested the solutions that make the most sense for the issue on the water heater but honestly if you are not sure about what you are doing, you should call an experienced person to solve it for you.
The electrical appliances can be dangerous to fix on your own in case there are deep issues. In these cases, ask for backup.
