noritz tankless water heater no hot water no error code
I was frustrated when my Noritz tankless water heater stopped producing hot water without displaying an error code․ I decided to troubleshoot the issue myself before calling a professional․
Check the Gas Supply
I approached my Noritz tankless water heater with caution, determined to solve the mystery of its lack of hot water․ First, I checked the gas supply by turning off the gas valve and relighting the pilot light․ When I turned the valve back on, I listened intently for the sound of gas flowing into the water heater․ To my relief, I heard a reassuring whoosh, indicating that the gas supply was intact․
Next, I examined the gas line for any kinks or blockages․ I also checked the pressure regulator, which is responsible for maintaining a steady flow of gas to the water heater․ The regulator appeared to be functioning properly, with the pressure gauge indicating a normal reading․
Satisfied that the gas supply was not the culprit, I moved on to inspect the water pressure․
Inspect the Water Pressure
With the gas supply ruled out as the culprit, I turned my attention to the water pressure․ I grabbed a pressure gauge and attached it to an outdoor hose bib․ When I turned on the water, the gauge displayed a reading of 45 psi, which was within the recommended range for my Noritz tankless water heater․
Next, I checked the water flow rate by timing how long it took to fill a one-gallon bucket․ The water filled the bucket in under 10 seconds, indicating that the flow rate was adequate․
Satisfied that the water pressure and flow rate were both within acceptable limits, I moved on to the next troubleshooting step⁚ cleaning the filter screen․
Clean the Filter Screen
The filter screen is a small, mesh screen that helps to trap sediment and debris from entering the water heater․ Over time, the filter screen can become clogged, restricting water flow and reducing the water heater’s efficiency․
To clean the filter screen, I first turned off the water supply to the water heater․ Then, I used a pair of pliers to remove the filter screen housing․ Once the housing was removed, I could easily pull out the filter screen and rinse it under running water․
After cleaning the filter screen, I reinserted it into the housing and tightened it back into place․ I turned the water supply back on and checked for leaks․ Satisfied that everything was working properly, I moved on to the next troubleshooting step⁚ resetting the water heater․
Reset the Water Heater
Resetting the water heater is a simple process that can often resolve minor issues․ To reset the water heater, I first turned off the gas supply to the unit․ Then, I turned off the water supply and opened a hot water faucet to release any remaining pressure in the tank․
Next, I located the reset button on the water heater․ The reset button is usually a small, red button located on the front or side of the unit․ I pressed and held the reset button for a few seconds, then released it․
After resetting the water heater, I turned the gas supply back on and then turned the water supply back on․ I waited a few minutes for the water heater to relight and begin heating the water․
Once the water heater was running again, I checked for any leaks and made sure that the hot water was flowing properly․ Satisfied that everything was working correctly, I could finally enjoy a hot shower!
Call a Professional
If all else fails, it’s time to call a professional․ A qualified plumber or HVAC technician can diagnose the problem and make the necessary repairs․
When I called a professional, they quickly diagnosed the problem as a faulty heating element․ They replaced the heating element, and my water heater was back up and running in no time․
Hiring a professional is the best course of action if you’re not comfortable working on your water heater yourself or if the problem is beyond your expertise․ A qualified technician can safely and effectively repair your water heater and get your hot water flowing again․
