By following these steps, you can successfully fix a humming water heater in no time! With regular maintenance and inspection, your hot water heater should provide you with many years of reliable service.
Tips for How Do You Fix a Humming Water Heater
- Shut off the water heater power supply by switching off a breaker in the main circuit panel or turning the gas switch to “Off” for a gas unit.
- Allow time for the water in the tank to cool before proceeding with any maintenance work. It may take several hours for the water to cool down, depending on how long it has been since your last maintenance visit.
- Inspect the upper and lower elements of a tankless or electric-powered heater for corrosion, scale buildup, and debris in the heating chamber.
- Clean out any sediment that has collected on the bottom of an electric-powered heater with a putty knife.
- Use a wire brush to clean any corrosion off the element connections of either an electric- or gas-powered heater.
- Check the thermostat and reset it to its lowest setting, then gradually increase its temperature until the desired water temperature is achieved.
- Make sure that all electrical connections are tight on an electric-powered heater.
- Test the water heater’s pressure relief valve before restoring power to it, discharge any excess water, and replace the valve if necessary.
Follow maintenance tips and follow up with regular inspections of your water heater annually to keep your appliance running smoothly.
Has the Water Heater Been Regularly Inspected and Maintained?
If a humming water heater has not been regularly inspected and maintained, it might be the source of your woes. A few common culprits include mineral deposits from hard water buildup or corrosion in the tank. Either can cause obstructions that create excessive noise.
If there is too much sediment buildup, hot spots may damage the heating elements and even cause the tank to burst. Fortunately, most water heater hums can be fixed through regular maintenance, such as draining and flushing out the water heater or replacing corroded components. If your water heater has been regularly maintained, then it is likely that a different problem might be causing the noise.
For instance, loud noises from electric water heaters may be the result of a loose heating element. A loose heating element can cause electrical arcing, which creates a loud buzzing noise. Replacing the heating element or tightening it should fix this issue. If your water heater is gas-powered, then check for any leaks in the pipes or valves that could be causing excessive noise. You may need to call a professional if the issue is more complicated and requires special tools or expertise to fix it.
Is the Sediment Buildup Inside the Water Heater Tank Excessive and Causing Damage or Blockage?
If this is the case, you will need to flush the water heater tank. To do this, turn off the power or gas supply to your water heater and shut off the cold water inlet valve. Attach a garden hose to the drain valve at the bottom of the tank and run it outdoors or into a bucket. Open up both hot and cold water valves and turn the drain valve. Flush the tank until all sediment is gone. Reattach the hose, open the inlet valve, and turn on the power or gas supply to activate the heater.
If your humming water heater isn’t caused by excessive sediment buildup, it could be due to an obstruction in one of the pipes connected to the tank. Check for blockages, corrosion, and other water supply issues in both the cold and hot water lines. If you find any, you should take steps to fix them immediately. This could involve calling a plumber or replacing old parts with new ones.
Does Your Home Have an Electrical Grounding Issue?
If your water heater is humming, it could be caused by an electrical grounding issue. An electrical grounding issue occurs when the electricity flowing through your home and appliances isn’t correctly grounded. Electric current can build up in a loop without proper grounding instead of properly dispersing into the ground or surrounding materials. This loop causes a buzzing sound that can be heard in your water heater.
To fix this issue, you can try checking the grounding wires and ensuring they are properly connected to the metal frame of your water heater. If the wires are not correctly connected, you can use a wire cutter to remove them and then re-attach them securely. You should also check for any loose wires near the water heater and ensure they are properly connected.
If this doesn’t solve the issue, you may need to contact a professional electrician who can inspect the wiring throughout your home and determine if an electrical grounding issue needs to be fixed. The electrician will also be able to provide guidance on how to ground your water heater properly.
Has the Heating Element Already Been Replaced?
If the heating element of your water heater has already been replaced, then it is likely that the humming noise you are hearing is due to a buildup of sediment deposits on the bottom of the tank. To fix this issue, you will need to flush out the tank with clean water and remove any built-up sediment. The process for how to flush a water heater tank is outlined below.
- Turn off the electricity to the unit using the fuse box or breaker panel.
- Shut off the cold water line that supplies water to the tank, typically located near the top of it.
- Connect a garden hose to the drain valve at the bottom of your tank and run the other end of it to a nearby drain or outside.
- Open the valve at the bottom of the tank, allowing water to start draining out.
- Once all of the sediment has been flushed out, close off both valves and turn on your cold water supply line again.
- Turn back on your power source to the water heater.
After following these steps, your water heater should no longer be humming and you can enjoy hot water without any annoying sounds.
Could an Electrical Issue Be Creating the Hum?
If your water heater is humming, you should first check the electrical connections. If there are any loose wires, tighten them and see if that solves the problem. Additionally, check all of your circuit breakers to ensure they’re turned on and not tripped. While these steps may seem simple, they can effectively solve the humming issue.
If all of your electrical connections are secure and you’ve ensured all of your circuit breakers are working properly, the next step is to check for rust or debris that may be clogging up your pipes. Rust can build up inside your water heater, leading to a humming noise when it vibrates against the walls. Remove any debris or rust and see if that solves the issue.
If neither of these steps resolves your humming problem, you may need to replace some components in your water heater. If there is a cracked heating element or thermostat, it can cause vibrations which result in a humming noise. Replacing these parts will likely fix the issue. Finally, if you’ve checked all the above and your water heater is still humming, it may be time to call a professional. A qualified technician can diagnose and repair any issues with your water heater that could be causing the humming noise.
