When is a modern boiler just a malfunctioning computer?
Panicking my way through Worcester's immense user manual in search of 'pilot light' or some equivalent produced nothing but I noticed that it wasn't just the light but the entire display panel that had gone dark.
Just on spec, I tried the computer reset trick - turned the electrical supply to the boiler off and on again, in case that might tell me whether I'd have to replace the rather inaccessible fuse. The boiler then came back on, pilot light and all. Should that be the user's first recourse if their boiler suddenly goes dark?
