CH/WH programmer not working

[mrtapir]

Hello all,

last week our programmer (british gas UP1) stopped working, the display started fading, and although we could change between on, timed, once and off, it would not send a signal to the heating/hot water. Over a couple of days the display completely faded away.

Ive bought a Drayton lifestyle programmer and the backplate is the same so i fitted that last night over the same backplate (as advised by shop) but nothing happened.

Ive checked the wiring in the backplate and also in the larger board where all the controls are wired into. However, i did notice that in the board there is a 2 amp fuse, whereas the programmer and also the cylinder instructions say it should be 3 amp. would this make a difference? Can i fit a 3 amp fuse 'socket' onto the exisiting wiring board? or would this be something else like a valve issue or something?

Thanks, Rich

Have you read the instructions.

Have you read the instructions.

yes i did, can you tell me does the original problem of the old programmer display disappearing suggest that the programmer was knackered?

Yes, or the battery is dead.

I would change the backplate first.

If you label all the wires you shouldn't get into too much trouble.
