No heating or hot water

Hi I have an Ideal E type conventional flue gas boiler. On Tuesday night there was a power cut in the area. Since then the boiler has gone a bit funny.
The fuse in the spur that supplies the boiler had blown. I have found the electrical fault that caused this, and rectified it (I'm a sparky).
The programmer and zone valves are all working fine and the pump is whirring away (but I'm not sure if it is pumping).

When you turn on the programmer (either heat or hot water) once the zone valve(s) have opened the pump starts, and the boiler fires up.
The boiler will stay lit until the stat clicks off (the thermo couple jobby on the front of the boiler).
By this point the pipe coming out of the top left of the boiler is properly burning hot, but stays cold above the gate valve and on the pipe that the pump is on.
It seems to me that no water is flowing through the heat exchanger but I don't know.

I have checked the little header tank in the loft and this is full, as is the one in the airing cupboard above the cylinder.

I took a few photos to hopefully give you a clue. (Sorry they arn't very clear but only had my phone)

Does the water not circulate with either HW or CH?

Are you sure all the gate valves are open? Did you close any of them recently? Even if you opened it again, the inner gate may have remained shut.

Check the pump by opening the screw cover on the end and touching the spindle inside. You should feel it rotating. It is still possible that the impeller has detached from the spindle, but checking that would involve removing pump.

Even if the feed tank is full, you might have a blocked feed pipe and therefore a lack of water in the system. Check this by venting a little water from some rads (via air vents).

Hi, All sorted now thanks.

I feel a bit special now
