Other Fault Codes you may encounter
If you see a spanner symbol this could mean two things. Firstly, your boiler is in service mode. Secondly, it could mean there is a blocking issue. It might be a temporary issue if the boiler is blocking the code. However, if the error keeps on showing, it might lock the boiler after few attempts.
