What is the Navien Error Code 003
If you have a Navien tankless water heater, you may have seen the error code 003 before. This code indicates that there is a problem with the water heater’s exhaust fan. The fan is responsible for venting the combustion gases from the unit, so it’s important that it is working properly.
There are a few things that can cause the error code 003 to appear. One possibility is that the fan itself is defective and needs to be replaced. Another possibility is that there is something blocking the fan from spinning freely, such as a piece of debris. If this is the case, you’ll need to remove the obstruction and then restart the unit.
If you see the error code 003, it’s important to take action right away. A malfunctioning exhaust fan can cause the unit to overheat and potentially catch fire. If you’re not sure what to do, you can always contact a Navien service technician for help.
What causes the Navien Error Code 003
Navien Error Code 003 can be caused by a variety of factors, but the most common cause is a clogged or restricted heat exchanger. The heat exchanger is responsible for transferring heat from the boiler to the water, and if it becomes clogged, it can prevent proper heat transfer. This can cause the water to become too hot, which can lead to the error code. Other potential causes of the error code include a faulty pressure relief valve or a problem with the circulator pump. If you are experiencing this error code, it is important to contact a qualified technician who can diagnose the problem and make the necessary repairs.
How can the Navien Error Code 003 be fixed
If your Navien tankless water heater is displaying the error code 003, it is likely due to a problem with the heat exchanger. The heat exchanger is the part of the water heater that actually heats the water. It is possible that the heat exchanger is not getting enough water flow, which would cause it to overheat and display the error code.
There are a few things that you can do to try to fix the problem yourself. First, make sure that there is nothing blocking the water flow to the heat exchanger. If there is, remove it and see if that fixes the problem. If not, you may need to descale the heat exchanger. This involves using a special solution to clean any build-up off of the heat exchanger.
If neither of these solutions works, you will likely need to call a professional to come and take a look at your water heater. They will be able to diagnose the problem and give you an estimate for repairs.
