Water Heater Problems & Solutions

Read more to know why my hot water heater is not working.

Loose or Damaged In-Line Valve

Unlike a water leak near the bottom of your water tank, a water leak on top of your system is simple to repair. A faulty in-line valve is a frequent source of water tank leaks. This is a metal piece that you twist to stop or start the water from coming out. To obtain this, you’ll need to tighten the nut that secures the ball or in-line valve. If the leak gets worse after you’ve tightened it, you’ll need to go to your local hardware store and buy a new in-line valve for your water heater.

Damaged Pressure Relief Valve

Most water heaters come with a pressure release valve designed to release pressure from the water tank when it reaches an unsafe level. If the valve on your water heater starts to leak, you should buy a new one. You can buy it online or in your local store. Removing and replacing pressure relief valves is not hard.

 No Warm Water

If you have an electric water heater in your home, a broken heating element is the most common cause of a lack of hot water. Water heaters include two heating components responsible for heating water in the tank. You will have little to no hot water available if one heating element begins to fail.

Many problems can stop the warm water from coming out of a gas heater. A broken or malfunctioning gas valve or a blown-out pilot light might be blamed. A damaged thermocouple might also be the reason for the lack of hot water in your home. Although all these parts are replaceable, many can be replaced by simply replacing new components. If your hot water heater stops working, either obtain new parts or call a professional plumber to assist with a water heater repair.

Low Supply of Hot Water

Do you have a hard time keeping your water warm? A cracked dip tube might be the source of this problem. This tube is to push cold water down your tank. Cracks can form in the tube and cause the water to flow at the top or middle of your tank. Because the tank is too small, cold water will be sent to your home’s faucets and showers. Installing a new dip tube on your system is the only way to repair this hot water heater issue.

Because replacing the dip tube is time-consuming, we recommend getting assistance from a professional. If your water is not warm, this means that there may be a lot of dirt in your water tank. As your water heater nears the end of its life cycle, minerals in the water, such as magnesium and calcium, will accumulate at the tank’s bottom. As the minerals get bigger, there is less room in the water tank. To fix this problem, you need to flush your water heater.

Water Is Too Warm or Cold

Water temperature in your shower may be adjusted by changing the settings on your thermostat if it feels unpleasant hot, or cold. Setting your water to a high of 120 degrees Fahrenheit might help you save money on your energy bills. This is a great temperature to use if you’re concerned about scalding or skin burn.

Is this temperature too chilly? To make your baths more pleasant, you may adjust the thermostat to 140 degrees Fahrenheit. This indicates a faulty thermostat if your hot water heater stops working when the temperature is changed. To repair or replace your thermostat, get in touch with a licensed plumber or heating expert in your region straight away.

 Low Water Pressure

Low water pressure is not always the fault of your water heater. If you reside in an older home with smaller water pipes, the water flow will be restricted before reaching our kitchen or bathroom skins. The only way to fix the hot water heater problem is to connect new ¾ inch water lines. Another problem that may negatively impact your water pressure includes calcium deposits in water pipes.

When magnesium and calcium accumulate in your pipes, the diameter of your water lines will decrease. As a result, the water in your water heater will not be able to reach your sinks or appliances efficiently. Because drywall must be removed when replacing water pipes, an average homeowner who does not possess a plumbing license will be unable to repair this hot water heater problem.

Discolored Water

The water coming out of your sink should be clear. Do you notice discolored water in your house? This indicates deterioration in the water tank or the anode rod of your water heater. Fortunately, this problem can be fixed if it is detected early enough. If your home’s hot water heater isn’t working properly, contact a nearby plumber to perform repairs or adjustments.

A licensed plumber or HVAC technician will be able to remove and replace the anode rod in your system easily. When your water tank’s inside is corroded, tiny fractures may form. Water will seep onto the flooring and furnishings of your house as a result of this. Unfortunately, most types of water tank leaks cannot be fixed. You will need to buy a new water heater to fix the problem. It’s more cost-effective to report early indications of corrosion to a professional so they can be addressed.

Takes a Long Time to Produce Warm Water

It should not take more than a few minutes to restore hot water once your water tank is empty. If it takes an hour for your water heater to provide warm water, this is a sign of a clogged burner orifice. On the other hand, a decreased supply of hot water may be addressed by boosting the gas pressure in your water heater. If you have a problem with your hot water heater, it’s best to call someone licensed in your area. They will be able to help you when the problem happens.

What would cause a hot water heater to stop working?

There are a few common reasons why a hot water heater would stop working. The most common reason is that the water tank has simply run out of hot water. This can be due to either a lack of use or a leak in the tank that’s been going on for some time without being noticed. Another common reason is that the pilot light has gone out. If this happens, it could be because the gas has been turned off to the unit, something is blocking the flow of air to the pilot light, or the pilot light itself has gone out. Finally, the thermostat may have failed, preventing the heater from reaching the desired temperature.

Is there a reset button on a hot water heater?

On your electric water heater, you’ll find a reset button. It’s usually red and frequently situated near the thermostat. It may be hidden behind a detachable metal panel on the device—and then behind some insulation. Push and release the button after you’ve found it.

Why is my hot water not working, but my cold water is?

A control valve has three possible reasons: it’s stuck open; it failed internally (appearing to be turned on but really “off” inside due to a broken valve stem part); or a pipe elbow or valve may have become partially blocked.

How much does it cost to replace a water heater thermostat?

The average cost of replacing a thermostat is between $100 and $300. The majority of other repairs are equally inexpensive. There are two distinct sorts: gas and electric. A gas device works using a gas flame, whereas an electric device works with electric components or coils.

How do you check a thermostat on a hot water heater?

The thermostat on a hot water heater can be checked by turning off the power to the unit at the breaker box, removing the cover to the tank, and locating the thermostat. The thermostat is a small metal object with two wires attached to it. Touching these two wires together will cause the heater to come on. If this doesn’t work, there is likely a problem with the thermostat, and it will need to be replaced.

Is it normal for my water heater pilot light to go out?

It’s not normal for your water heater pilot light to go out, but it does happen from time to time. There are a few common reasons why this might happen: the gas has been turned off to the unit, something is blocking the flow of air to the pilot light, or the pilot light itself has gone out. If you’re having trouble getting your water heater pilot light to stay lit, there are a few things you can try to get it going again.

First, make sure that the gas is turned on to the unit and that nothing is blocking the air flow to the pilot light. If that doesn’t work, you might try relighting the pilot light using a match or a lighter. Finally, you may need to replace the pilot light assembly if all else fails.

Why is my electric hot water heater not working?

If an electric water heater is not producing hot water, it could be a simple problem like a blown fuse or tripped circuit breaker. Additionally, some electric water heaters have a circuit-style safety switch located near or on the thermostat.
