Most likey problem is the diverter valve, not energising fully. This in turn will not move the little plastic lever arm that actuates the microswitch on the side, sending the signal to ignite.
You can buy a diaghram kit from most local plumb centres, you need to replace the diaghram and seals, don't forget the silicon grease to ensure the plunger doesnt stick. Kits less than a tenner.
You should have noticed before it stopped working completely the water had reduced in temperature before the weeks it failed.
To make sure it is a diverter valve fault, depress the microswitch if you can, when the hot water is flowing and hey presto the demand for hot water light should shine.

You have a faulty diverter valve, this is a fiddly job, you need to call in a 'Gas Safe' engineer to diagnose and replace this
I hope this helps

SOURCE: I have a Honeywell ST499A/ST699B
I have an old Honeywell ST499A/ST699B thermostat. It still works OK but when we have a power cut I have to re-programme everything. Presumably this is because the battery needs replacing. I cannot find a way of opening the control box to get into the unit to replace the battery and in any case I’m not sure if the battery is renewable?
