ERROR CODE: F07
ERROR TYPE: High Exhaust Gas Temperature Error
PROBABLE CAUSE: This occurs when the exhaust gas temperature exceeds 95°C.
SOLUTION:
1- Check if there is water in the boiler by turning on the drain valve.
2- If there is no water in the boiler and the pressure sensors are measuring pressure, replace the pressure sensors. Fill the boiler with water up to
1-1.5 bar.
3- See if there is a difference between the value read for the parameter “i06”in the inquiry Menu and the temperature you measure with the measuring device. If there is a difference between these two values, replace the flue gas sensor.
4- The pump connection cables may be loose or displaced or lose their conductivity. Check the connections. If there is a problem, replace the cables and reset the device.
5- Ensure that the pump is working properly. If there is a problem, replace the pump.
6- Check if there is congestion in the installation.
7- There may be congestion in the waste gas part of the heat exchanger or the space between the helical pipes may not be appropriate. In this case, clean the heat exchanger and make sure that the space between the helical pipes is not less than 0.4 mm.
8- If the problem persists, replace the mainboard.
