Glowworm Economy Plus Not Lighting

Was called by a customer today because they had no heating or hot water. The boiler sounded as if it was working but there was no flame. When I looked at it I could hear the fan running so I knew it was receiving demand. There was no flame visible and there was no sound of ignition.

Usually in most cases I would assume that the fan was running slowly or that the air pressure switch was not working. However, I have seen this problem happen a number of times on these boilers and new it was likely to be a blocked air pressure switch hose. I pulled off both the hoses at their connection to the fan and 'rodded' the connections using an Allen key (with the boiler off obviously). I then reconnected the hoses, replaced the cover, and fired up the boiler succesfully.
