Help Needed. Dead Programmer????

[bantam]

Can anybody help?
I came home to find that the boiler (glowworm) would not fire up when I advanced the programmer to ch or hw.The programmer is a ACL LS522. The pilot was still lit though.
I turned the programmer off at the wall and turned it back on again only too find out that no digital reading appeared. is it dead i thought? i then unscrewed the device from the back plate and took out the battery which was rather corroded at the bottom. I cleaned up the battery and put it back in and a faint reading appeared, however this soon went. I replaced the device on the wall plugged it in and nothing!

Would a dead battery mean that the programmer would not come on when turned on at the mains?
And why initially would my boiler not ignite when the programmer was working (or seemed to be)
Could i have a serious problem with my boiler also?
what do i do next?

Check the fuse in the fused spur that provides power to the programmer.
If its blown it could be cos one of the wires has shorted somewhere in the electrical control system.
Dont replace a fuse more than once get it checked out if it blows again.

Is it a back boiler you have and if so has it been serviced lately

I checked the fuse in the plug from the programmer to the mains and this was fine. Plugged in another electric al item and this worked.
No its not a back boiler.
The boiler is a glow worm space-saver mk2

Likely to be a loose wire in the back of the programmer.
Battery health affects some programmers and not others so try changing that as well.
