Mend Switchmaster 805 Heating Hot Water Programmer

Hot Water System?

Have got a Switchmaster 805 programmer connected to the central heating system, which i have had for many years. Over the last year the Hot Water System does not seem to work unless you put on the Central Heating Constant Button so in the summer you have to have the heating on just to get the hot water 'Hot'. Can you suggest what the problem might be. Does it mean a new programmer? Await to hear.
