hi
I have a grant oil fired boiler that is approx 4 years old. Recently the burner has started locking out. If I press the reset button it will start and fire and heat enough water for a shower etc... but then locks out. Sometimes it will stay on for a couple of days and give hot water on demand but will then lock out again. This was serviced around 6 months ago and a new nozzle was fitted and a new filter at the discharge point of the tank. Is the ‘steam’ colour any indication of what is happening? When this was operating perfectly this was white but now sometimes it white but other times when running is is almost colourless. I am guessing not getting to high enough temperature. I have tried to bleed fuel a few times and each time it seems to bubble and ‘fizz’ a bit. Is air getting in? There are compression fittings at tank (filter), fire valve and at 90 degrees just after fire valve where it comes through the wall
Thanks
