The hot water function light is bright when I press advance and I get hot water but the light on the heating side fades and disappears and my radiators remain cold.HELP.

If I was checking this I would bridge out the live and c/heating connections in the back of the clock to see if heating comes on,if so the clock needs replacing,I would recommend a Horstmann CentaurPlus C27 programmer from Screwfix,they are as good but a lot cheaper
