Worcester Greenstar 40CDI - No Heating, and No Fault Code

[chug1957]

Hi,
This boiler starts, when heating is demanded, but cuts out after around 30 secs. Pump body is hot, and I can feel the impeller vibrating, so not sure if it is the pump. When the heating cuts out, no fault code is displayed. Boiler is holding pressure.
Domestic Hot water is working fine, although there is a slight leak on the flow sensor which is not related.

Any ideas before I start to investigate further? I am tempted to remove the pump in any event, but would rather leave alone if this is not likely to be the fault.

Thanks
