Here's some pictures of a boiler breakdown from this morning {saturday}. Our customer was faced with a possible weekend of no heating and no hot water. Luckily he rang us and I was able to attend within the hour.
The boiler is an Ideal 'Isar' 30KW combination boiler that's around five years old. It was attempting to ignite before locking out and displaying the 'LF' fault code.
Here's the boiler with the front case and sealing panel both removed. 'LF' is a flame error fault code but it can be one of several faults.
The first thing I check is the ignition electrode which is highlighted below.
I was right first time. It has been distorted by heat making the gap too large for the spark to bridge. We look after a lot of these boilers and carry a spares kit consisting of every part enabling us to fix them in a single visit.
