The Rinnai error code 14 is caused by a problem with the pressure switch. This error code can be caused by a variety of things, but the most common cause is a clogged pressure switch. The pressure switch is responsible for detecting the pressure in the gas line and signaling the control panel when the pressure is too low. If the pressure switch is clogged, it will not be able to detect the pressure in the line and will cause the error code 14.

1. Check that the gas is turned on
- Check the pilot light is on
- Check the gas valve is open
- Check the gas line is connected to the gas valve
- Check the gas line is not kinked
2. Check that the pilot light is lit
- Check the fuses. If the pilot light is not lit, the fuses are likely blown.
- Check the electric panel. If the pilot light is not lit, there may be a problem with the electric panel.
- Check the pilot light switch. If the pilot light switch is not working, the pilot light may be blown.
3. Check that the igniter is clean
To check that the igniter is clean, one would first need to remove the cover and inspect the igniter. If it is dirty or has any visible damage, it will need to be replaced. Additionally, if the igniter does not seem to be sparking and there is no heat coming from it, it may also need to be cleaned.

- Remove any obstruction from the burner orifices using a vacuum cleaner.
- Turn the gas on to the range and wait until the flame has come back on.
- Check that the flame is reaching all of the burner orifices.
- If the flame is not reaching all of the burner orifices, turn the gas off and check the orifices again.
- If the orifices are still blocked, call a professional.
Still not working? maybe try one of these options:
- Check for any loose connections.
- Check that the control valve is in the correct position.
- Check for any debris in the gas line.
- Check the pressure of the gas.
- Check the temperature setting.
