We had a bloke come to give our boiler it's first year service, he took the front cover off the boiler via its 2 screws & then started using an electronic device.
he said he could tell that the boiler didn't need cleaning by the reading he got on his device so there was no need to open it up further.
was he telling the truth or have we been conned ?
