Central Heating Controller/Valve

[Fredy]

Hi... When I set the Central Heating Controller to automatically switch the heating on or do manual overide, the Hotwater Controller shows the heating system to be ON, the pump either starts for a short period (say 10 mins) and then stop or the pump does not start at all. The Central Heating Controller shows it on all the time.

The Hot water works fine. Any ideas.
Thanks in advance

I am not a plumber or heating engineer, but if your pump has trouble stsrting or runs for a short periopd of time and you have changed nothing i would say the pump is on its way out
you can get one from
