Why Your Tankless Water Heater Is Not Working

If you’re like most homeowners in Burbank, you probably don’t think much about your tankless water heater repair. After all, everything appears to operate perfectly—until it doesn’t.

The “unless it doesn’t” part might be problematic. When anything goes wrong with a tankless water heater, the cause is not necessarily clear. 

Sometimes it’s simply a little malfunction that can be resolved by turning off the electricity or washing out some silt in the pipes, but more significant concerns might arise. And if you don’t know what they are, you might wind up spending money on unneeded repairs—or, worse, risking a home fire!

But what if we told you that there was an easier way? What if we told you that there’s actually another way to fix your tankless water heater so that it works again? Well, there is! And we’re going to show it to you in this article.

In this article, we are going to discuss some common reasons why your tankless water heater isn’t working and how to fix it. And when it’s time to call a professional tankless water heater maintenance service provider.

Let’s take a look:

Common Tankless Water Heater Problems and It’s Time for Tankless Water Heater Maintenance in Burbank

Low Water Pressure

If your water pressure is low, it will be impossible for your tankless water heater to heat up enough water at once to provide hot showers for everyone in your house (or even just one person). 

The best way to fix this issue is to install an on-demand water booster pump (which should be done by a professional tankless water heater service company in Burbank, CA, like Agent Rooter). This will increase the pressure coming into the house so that your tankless heater can function properly.

No Hot Water

If you’ve observed that there’s no hot water coming out of your faucet, don’t panic! It could just mean that it’s time for the maintenance of tankless water heater. Try turning off the power to the unit for approx—15 minutes and then turning it back on again.

If that doesn’t work, you need to check the shut-off valve. A tankless water heater should be connected to a cold-water line in order to function properly. 

If there is no cold-water line or the valve is closed, the tankless water heater will not work.

Insufficient Hot Water

If there isn’t enough hot water flowing out of your faucet or showerhead, it might be because there is too much demand for hot water in the house at the same time. This simply signifies that it may be time to contact Burbank plumbers to replace or install a new tankless water heater!

You also need to check the drain valve and ensure it’s open if there is insufficient hot water in the current water heater. 

A tankless water heater functions by heating as much water as possible all at once, allowing it to offer an uninterrupted flow of hot water for longer periods of time than traditional storage tanks. More efficient tankless water heater vs. tank. However, if the drain valve is closed or partially opened, this can cause your tankless water heater to malfunction and provide only small amounts of hot water at a time instead of continuously heating more from the cold tap until it runs out completely (which is what happens when you turn on your sink faucet).

Temperature Fluctuations

If your water heater is running on its own schedule, it could be due to temperature fluctuations. 

The temperature of the water coming into the heater should always remain between 120 and 130 degrees Fahrenheit, but if there’s a sudden change in temperature, this can cause problems with the thermostat or sensor.

Ignition Failure

The ignition system is what lights your burner when you turn on your hot water faucet. 

If this component isn’t working properly, then it won’t ignite and heat up the tank of water. 

If you notice that your burner turns on but doesn’t light up, then this is probably why!

Error Codes

If your tankless water heater is not working, you should check for error codes. 

By pressing the “Test” button on your tankless water heater’s control panel, you can see if there are any error codes present. If there are no error codes, then it’s time to take the next step.

Mineral or Sediment Buildup

If there are no error codes, but your tankless water heater still isn’t working, mineral or sediment buildup may be the culprit. 

Mineral and sediment buildup can occur when minerals in your water combine with calcium deposits inside the pipes of your tankless water heater. This will cause an electrical short and prevent it from heating up properly, so be sure to flush out your tankless water heater regularly or opt for tankless water heater maintenance services in Burbank, CA!

Water runs hot, then cold, then hot again.

This issue is usually caused by a faulty thermocouple. The thermocouple is what tells the pilot light when to turn on and off. 

If the thermocouple goes bad, it may not be able to sense the heat from the pilot light correctly, which causes it to burn out much more quickly than normal. 

You can call a tankless water heater service near me if you aren’t sure how to do it right away so they can get everything up and running again quickly!

The Water Smells Bad Or Looks Discolored

If the water coming out of your tankless heater smells bad or looks discolored, it’s probably because of an issue with the tankless heating element. That may be because it’s starting to corrode, which can happen over time if you haven’t been diligent about maintaining it. 

You may also have an issue with sediment buildup in your tankless heating element, which can also cause a bad smell and/or poor performance from your heater. 

In either case, you’ll need to call for a tankless water heater repair Burbank service company to replace the heating element in order to resolve the problem.

Water Leaking

The most obvious cause of a leaking tankless water heater is a malfunctioning pressure relief valve (PRV). These valves are intended to relieve excess pressure that accumulates in the tankless water heater while it is not in use. Nevertheless, they do not always function properly, resulting in leakage. Replace your PRV with an improved one with a superior design and seal better against leaks to solve this problem.

Gas Leak

If your tankless water heater begins to leak gas, it might be because you’re using the incorrect type of gas for your model. Be sure you’re utilizing natural gas instead of propane gas or another form of fuel since this can assist in avoiding future leaks!
