Blocked Exhaust

Depending on the type of water heater you have, you can use electricity, propane, or natural gas to create warm water. Natural gas or propane water heaters are connected to the drainage pipes leading out of your home. Pipes are designed to release toxic gases used during combustion.

 To prevent harmful gas leaks, a waterless water heater is designed to deliver the error code when the exhaust pipe closes. Since gas pipelines are connected outside your home, items such as a bird’s nest, rodents, chopsticks, or litter can form blockages that interfere with the flow of natural gas.

Do a plumbing test outside your home to make sure you see a nest or mice in the exhaust system. If your water heater without a tank shows an error code, the source of the problem may be a crack or a hole in the gas pipeline. In addition, do a check to make sure the pipe connection is secure. A loose exhaust pipe can cause gas leaks in your home. 

Accumulation of Minerals

If you own a water-free water heater or are moving from a conventional to a water-free tank heater, it is also important to check the water filter on your water heater, especially if you have a water source.
