Th reason I'm asking is that I need a new programmer. Ours topped working and my cousin fitted a Switchmaster SM300, but that only operates the heating- we have no hot water- I considered the Switchmaster SM400 but can't run water and heating independently so am thinking about the Switchmaster SM805 which is for fully pumped systems- so will it work with a Worcester 9.24 Electronic. Sorry for being such a plank but I haven't got a clue about plumbing or heating systems.

it's a combi you only need a single channel switch
Firstly thank you all for your advice so far. I'll tel you the full story of the problem we've had. It's a 15 year old Worcester 9.24 Electronic combi boiler with a fitted timer/programmer. There was no problem at all with the water, but even though the light was coming on to indicate that the timed central heating should be on, it wasn't. If I banged the front panel, it would come on- it switched itself off as normal at the end of timed period. My cousin is a plumber and he had a look at it and concluded that there was a fault with the timer so he wired from the boiler to a different timer- a Switchmaster SM300 and the heating works fine BUT since then we have no hot water. When we run the hot tap the boiler just isn't firing. My cousin thought maybe we needed a different programmer because the Switchmaster SM300 only has a switch for heating on/off/timed so I have been looking into getting a different model,hence all my questions about whether a SM400 or SM805 would work. But I've also been told that the water should still work irrespective of the timer switch- any help/advice greatly appreciated!
this is correct
It is likely to be the diverter valve stuck. Boiler will fire for hot water but diverter won't move when heating demanded so won't operate microswitches to fire boiler.
You need a suitably qualified person to check the live signal from the controls is geting to the boiler, then to remove microswitch hloder from DV depress both switches, boiler will fire, this is just to establish the fault. Then go out and geta DV and fit it. £77 plus vat from memory.
Reasonably good boiler, worth a DV.
