Paloma Gas Water Heater Isn’t Heating Water!

Paloma gas water heaters are designed to last a long time, but like any other appliance, they may experience problems over time. One of the most common issues is the heater not heating water. The pilot light may be the culprit in many cases.

When the pilot light goes out, the gas supply to the heater is cut off, and the water does not heat up. To troubleshoot the pilot light, try relighting it, but if it goes out repeatedly, there may be an issue with the thermocouple.

Check for any blockage in the gas line to make sure that the gas is flowing correctly. If you are unable to identify the problem, it is best to contact a professional to diagnose and fix the issue.

Leaking Paloma Gas Water Heater!

If you notice water accumulating around your Paloma gas water heater, it’s important to identify the source of the leak. The most common causes of a leaking Paloma gas water heater are a faulty temperature-pressure relief valve or a leaking water inlet or outlet pipe.

Check for any visible cracks or damage to the tank, as this can also lead to a leak. Be sure to check the drain valve to ensure it is closed tightly. Once you have identified the source of the leak, it is recommended to contact a professional for repairs.

Ignoring a leak can lead to significant water damage or even a gas leak, so it is important to address the issue promptly.

Paloma Gas Water Heater Produces Lukewarm Water

Paloma gas water heaters are known for their durability and efficiency. However, at times, you may experience lukewarm water when using your heater. This can be due to a problem with the dip tube, which is responsible for directing cold water to the bottom of the tank for heating.

If the dip tube is broken or clogged, it can cause lukewarm water. Examining the dip tube should be the first step when troubleshooting problems with your Paloma gas water heater. You can either clean or replace the dip tube to ensure that your water heater works efficiently again.

By taking prompt action and following these simple steps, you can restore the hot water supply in your home in no time.
