Why Is No Hot Water In Kitchen Faucet?

Why Is No Hot Water In Kitchen Faucet?

Broken or Malfunctioning Heating Element

Hot water in the kitchen faucet comes through the water heater. There is a heating element in the water heater. If this heating element is broken or malfunctioning, it won’t heat up the water, and no hot water in the kitchen faucet.

The heating element is used to transfer its heat to the water. It brings the water to the desired temperature. In the faulty condition, it won’t be able to heat up the water and you will be left with cold water.

Sediment Buildup In The Water Heater

The buildup of minerals and sediment at the bottom of your water heater tank is among the most frequent causes of this annoying problem.

Minerals and other impurities may eventually be carried by the water that fills your water heater tank. The sediment from these pollutants may accumulate at the tank’s bottom. It may be difficult for the water to heat up if this sediment buildup forms a barrier between the heating element and the water. You might not be able to get hot water out of your kitchen faucet as a consequence.

Malfunction Thermostat

The thermostat is an essential part of the water heater. It is used to maintain the temperature of the water. It monitors the temperature of the water and when the temperature of hot water is below its set temperature, the thermostat sends signals to the heating element and raises the water temperature. But if the thermostat is malfunctioning, it won’t send the signal and you get cold or lukewarm water.

Leaks In Hot Water Supply Lines

Leaks in the how water supply lines cause a lack of hot water in the kitchen fixture. It may happen due to corroded pipes or wear and tear.

Corrosion can occur when pipes are exposed to water, air, and other elements, which causes the metal to deteriorate over time. This can cause cracks, holes, or other sorts of damage to the pipes, leading to leaks.


Wear and tear is another cause of leaks in the hot water supply line. Pipes can wear out over time owing to regular use or other causes such as high water pressure. This might create cracks or damage to the pipes, resulting in leaks.

Flushing The Water Heater Tank

To remove the buildup and sediment, flushing the water heater tank is a good idea. It restores the water heater to its initial state. If you flush the water heater once every six months, you can improve its water quality and lifespan.

Buildup slows down the water heating process and increases the water bill. Here are the steps to flush a water heater tank.

  • Switch off the water heater or the gas supply.
  • Turn off the heater’s cold water supply.
  • Connect a garden hose to the drain valve at the base of the water heater tank.
  • Run the hose outdoors or to a floor drain, keeping the hose end lower than the drain valve.
  • Open the drain valve and let the water in the tank drain until it runs clean.
  • Remove the hose and close the drain valve.
  • Switch on the cold water supply and allow the tank to refill before returning electricity or gas.

Replace The Heating Element

Replacing the heating element of the water heater is a relatively simple DIY solution that you can tackle with just a few tools and a bit of know-how.

First, make sure the power or gas supply to the water heater is turned off. It will make sure the water heater is in a safe condition to replace the heating element safely. Drain the remaining water from the water heater. To drain the water repeat the above flushing steps.

Use a screwdriver to open the outer body of the water heater. There are wires on the heating element. Disconnect those wires with a screwdriver. Also, remove the screw of the heating element and take it out from the water heater tank.

Install the new heating element in the water heater and tighten its screws and connect wires. When the installation of the heating element is completed, refill the tank with water and turn on the power supply.

Adjusting The Thermostat

If the temperature of the thermostat is too low, it won’t heat up the water, and hot water won’t come out from the kitchen tap. Adjust the setting of the thermostat to get hot water.

The water heater’s outside body has a tiny dial or knob with a label indicating the temperature in degrees Fahrenheit. Although most manufacturers advise setting the thermostat to 120 degrees Fahrenheit, you can raise the temperature if you feel like you’re not receiving enough hot water.

Increase the temperature setting on the thermostat. Only make minor changes at a time, and wait until the water heater has warmed up before checking the water temperature at the kitchen faucet.

Make sure the water is not too hot if there are kids in the house since hot water might burn their hands. Maintain a hot water temperature that is safe for kids.

Repair Leak of Hot Water Supply Line

  • Turn the hot water supply valve off.
  • Look for apparent indicators of wetness or water stains on the supply line to pinpoint the leak.
  • Tighten any loose connections with a wrench and replace any broken or worn-out parts as needed.
  • Remove and replace a damaged portion of the pipe as needed.
  • Reconnect the hot water supply valve once the repair is finished.
  • To ensure that the repair was effective, check the kitchen faucet for hot water flow.

How Do I Increase The Hot Water Pressure On the Kitchen Tap?

Increase The Hot Water Pressure

A blocked or filthy aerator can impede water flow and result in low pressure. Remove the aerator from the faucet and soak it for a few hours in vinegar to dissolve any buildup. Rinse it and reconnect it to the faucet.

Check that the hot water supply valve under the sink is completely open. It can impede the flow of hot water and produce low pressure if it is partially closed. Look for apparent evidence of damage, such as leaks or kinks, in the hot water pipes coming to the kitchen faucet. If you discover any damage, you may need to replace the damaged pipe parts.

If your water heater is not working correctly, you may have poor hot water pressure throughout your home. Check that the water heater’s temperature setting is suitable and that the tank is not too full or empty. If you suspect a problem with your water heater, you should contact a professional to diagnose and fix the problem.

No Hot Water In Kitchen Sink, But Everywhere Else

A blocked faucet aerator is one potential reason why the hot water in the kitchen sink isn’t hot enough. The tiny mesh screen known as the aerator, which is located at the tip of the faucet, can accumulate mineral deposits or debris over time. This accumulation may stop hot water from reaching the sink, leaving only lukewarm or cold water behind. Just use pliers or a wrench to remove the aerator from the faucet, clear out any debris, and then screw it back on.

A damaged or misaligned mixing valve is another probable reason why the hot water in the kitchen sink isn’t hot enough. If the mixing valve is malfunctioning, hot water may not be able to flow to the kitchen sink since it blends hot and cold water to provide the required temperature.
